Blegging re human ability to taste the change in ocean acidity
Ocean acidification has changed pH from about 8.2 to 8.1, so far.
My question - can we taste the difference? Might be an interesting factoid that we've altered the oceans so much that we can taste the difference, so imagine the effect on creatures whose biochemistry is dependent on that system.
I can't find the answer - anyone care to enlighten me? Please comment.
Reading around about acid manipulation in wine-making suggests this level of pH change is detectable to taste, but I'm not certain, and that's also starting at a very different level of acidity.

So the first ones not tasting the difference (by eating less) will be organisms who depend on carbonate forming organisms at the bottom of their food chain. I'm pretty sure that includes a bunch of humans.
It's a log scale for H+ ions IIRC. So 0.1 is more like a 10% concentration difference.
10% fewer stones means a lot if you are building a wall..
The change is about 25%, but as in most things concerning taste you would have to train the palate, using appropriate buffers. The added issue here is that there would be no associated odor, and smell is a huge part of taste discrimination.
There is a wide spread variation for "sensitivity" to bitterness among humans based in part on genetic variation. The ability to taste bitterness also depends on the passage of signal molecules passing from taste buds to neurones.
There are nearly 30 genes that code for tasting bitter which means there is a spectrum of bitterness 'sensitivity'. So it might, might be possible for some people to taste the pH difference of 0.1, especially if they carry all the dominant 'bitterness' genes.
Evolutionary geneticists theorise that the ability to taste bitter things helped our ancestors to avoid eating toxins which generally(?) have a bitter taste. Primitive cultures are supposed to have used the oldest clan member as a food tester to see how safe it was to eat never-seen-before, possible food sources.
Under Burgindy's cheerfully draconian medieval wine laws, any merchant caught messing with natural levels of alcohol, sugar or acidity was forced to drink a large measure of the adulterated product and put in the stocks to watch the executioner of Dijon smash and burn his stock in trade.
I suspect anyone can detect a .1 pH shift, for though lemon juice , which has a pH of ~ 2- 2.5, is only about ~%% citric acid, just a cc makes a glass of water refreshingly tart.
Where % unshifted = 5, if it's a fresh lemon.
the seas are average between 7.5 and 8.2.
The EPA regulations allow coastal waters to be between 6- 8.5.
Though we can say that a reduction in ph from 8.2 to 8.1 is acidification( the correct term is becoming less base) this is a term for the process not the outcome where the seas will never become acidic.

the pH of surface ocean waters will continue to decline. However, the term can also lead to confusion

less basic, but not acidic. Such a phenomenon could

The Market Failure
"While ocean acidification is well documented in a few temperate ocean waters, little is known in high latitudes, coastal areas and the deep sea, and most current pH sensor technologies are too costly, imprecise, or unstable to allow for sufficient knowledge on the state of ocean acidification"
WTF. You can measure pH of ocean water to 0.001 units and better. What are they actually moaning about? Automated systems, better sampling, satellite measurements?
mr Rabett i suggest you contact them and tell them they are wasting their money, or send them your own accurate measuring device and claim the reward,
http://oceanhealth.xprize.org/competition-details/overview
Wabbett:
"Automated systems, better sampling"
Mostly, yes. Affordable, accurate and efficient monitoring of ocean pH from shallow waters to the ocean depths.
So add affordable and efficient deployment oceanwide to the list, I guess. Sort of like Argo but a lot cheaper and more comprehensive coverage, and targetting pH?
Eli says: "WTF. You can measure pH of ocean water to 0.001 units and better."
The expanded measurement uncertainty of NIST's standard buffer solutions for pH is +/- 0.01 -- and these are under controlled laboratory conditions.
Given the reference solution has an uncertainty of 0.01 (NIST pH Metrology), measurement uncertainties for devices using these reference solutions will be even larger.
I'm not sure why Eli thinks we can measure pH an order of magnitude better than the uncertainty claimed by a National Laboratory under controlled conditions.
not sure satellites can measure ph of the seas either!!

"Effects of pH on coastal marine phytoplankton"
Most of the testing I have seen of the Ph of the sea has been done in coastal waters, the problem with this is the coatal waters vary by quite a range.
"Fig. 5 provides another view of the pH variability for
surface waters of lower Chesapeake Bay. The most frequent measurements are near pH 8.0 to 8.2, as would
be expected for seawater in equilibrium with the atmosphere. However, there are many measurements having pH well above and below the median pH"

Well, perhaps there is a difference in what NIST is after, and what someone measuring pH is after. pH is -log(aH), where aH is the activity of H+. The activity is molar concentration times the activity coefficient. Ideally the activity coefficient would be 1. Problem 1: activity coefficient depends on the environment. NIST is trying to achieve something like a standard suitable for SI units. In the IUPAC paper about this, from the appendix (pg 2194):
"As discussed in Section 5.2, the uncertainty due to the use of the Bates–Guggenheim convention
includes two components:
i. The uncertainty of the convention itself, and this is estimated to be approximately 0.01. This contribution
to the uncertainty is required if the result is to be traceable to SI, but will not be included
in the uncertainty of “conventional” pH values."

Spectrophotometric measurement routinely get a standard deviation for pH below 0.001. For example:
Purification and Characterization of meta-Cresol Purple for Spectrophotometric Seawater pH Measurements, Xuewu Liu , Mark C. Patsavas , and Robert H. Byrne,Environ. Sci. Technol., 2011, 45 (11), pp 4862–4868
"pHT(measured) = 8.0226 +/- 0.0002"
Go to wikipedia, look up pH, in the section called seawater, for what pHT is.
Rib Smokin' bunny
richard seems to confuse lack of a sensor with lack of a method for measuring. We can "accurately" measure ocean pH from its shallowest waters… to its deepest depths, a sensor would allow it to be done simply and in situ.
Rib Smokin' bunny
The bunnies need to remember how to search Rabett Run for all things. This is indeed a solved problem
Both the paper rib smokin' links to and the earlier post Eli links to state accuracy or uncertainties *relative* to a reference.
It is the accuracy of the reference - not the standard deviation of the measurements - that dominate the uncertainty calculation.
The Liu et al paper rib smokin' linked to also shows reproducibility between manufacturers can be 0.01 pH alone.
and we have another winner for the measuring of the seas PH at depth with any kind of accuracy

I hope it gives an accurate account of the ph of the seas from now on,, the only problem is what data are you comparing it against ( Sci. Technol., 2011) for the last 150 years.
Kevin said:"It is the accuracy of the reference - not the standard deviation of the measurements - that dominate the uncertainty calculation."
NIST is concerned with an absolute standard that meets SI qualifications for a standard. As of now pH is NOT an SI unit. The reason that NIST is so interested in activity is the tie to thermodynamics via fundamental theory. It MUST be measured by electrochemical potential by the definition they are using
People measuring ocean "pH" are not interested in what the activity coefficient is, just [H+], since they realize that
-log(a*[H+]) = -log(a) - log[H+]
Differences between pH and -log[H+] are exactly the same if a is relatively constant, no matter what the uncertainty in the value of a is.
Kevin also said:"The Liu et al paper rib smokin' linked to also shows reproducibility between manufacturers can be 0.01 pH alone."
and that purification leads to uncertainty in pHT of 0.0002. These corrections can be applied retroactively to old data.

Now you can rest easy that acid base chemistry is on a firm foundation, dissolving more CO2 makes water more acidic, always has, always will.
Rib Smokin' bunny
rib smoking bunnny,
ahem!!!! not acidic, the seas might be becoming less base,
remember
everything above 7 is alkaline everything below 7 is acidic , and we know the seas will never become acidic.
my little bunny, let me help you again,
"currrent projections of ocean acidification suggest that
the pH of surface ocean waters will continue to decline. However, the term can also lead to confusion
when it is wrongly assumed that the oceans will become acidic, when in reality, ocean pH is never expected to fall below 7.0; i.e., the oceans are becoming

I said: "CO2 makes water more acidic, always has, always will."
richard said:"ahem!!!! not acidic"
Acidosis in blood is pH below 7.3. It means more acidic than regular blood, not "acidic". In other words, claiming "more acidic" can't apply to anything where the end result is above pH 7 is idiotic.
Rib Smokin' bunny, who just happens to be teaching acid-base chemistry this week
my little bunny,
don't you worry, you can call the process of change from 8.2. - 8.1 acidification if you like, it would normally be called becoming less base , but i don't mind what words you use, just don't assume this will lead to the seas actually becoming acidic.

so
“The pH of marine waters is usually quite stable (between
7.5 and 8.5 worldwide)
so if are worried what will happen between the ph of 7.5 and 7 then so be it,
in other words and quite right too, you are worried about the change from an alkaline ph level of 7.5 to a possible neutral ph of 7.
Anon-101a here:
"don't you worry, you can call the process of change from 8.2. - 8.1 acidification if you like, it would normally be called becoming less base"
Most people would call it being more acidic. Normally it would be called "more acidic". Less base is more accurate, but it's abnormal to call it that.
Moreover, if you're now in the acid range, it would STILL be "less base" if you made it more acidic.
More acidic is the normal term.
Less base is the abnormal one.
less base was the term used until 2003 when Ken Caldeira coined the word acidification in one of his papers,
But as we know the seas will never become acidic,
Anon-101a here:
And less base is an abnormal term to use: more acidic is the normal term.
Anon-101a here:
"But as we know the seas will never become acidic,"
It will, however, become MORE acidic if you add carbon dioxide since CO2 and H2O produce Carbonic ***ACID***.
Adding an acid makes something...
MORE ACIDIC!
Anon-101a here:
And I believe you mean "acid" not "acidic". But even that presumes it is not possible to drop the pH to that of a chemical acid.
It's definitely possible to do this, just monumentally infeasible with the resources available to us on planet earth.
The reason that scientists use more acidic is that alkalinity is defined in a complex way for good reasons.
Another honey trap that dyslexic citizen scientists fall happily into.
A question for Eli:
As we know, the denialists LOVE to point out that the pH of sea water is above 7 and so basic. However, as we know, pH is defined a -log[H+], and the dissociation of H2O is endothermic. If we raise the temperature, the pH will drop. Has the warmed water become acidic? Certainly if we put the water under pressure and allow it to superheat above a couple hundred degrees C, it will dissolve rock.

ken Caldeira was the man who in 2003 coined the phrase Acidification in one of his papers, in his own words( see below) rhe seas are becoming "less base" not acidic.
he then goes on to write,
rent projections of ocean acidification suggest that
the pH of surface ocean waters will continue to decline. However, the term can also lead to confusion
when it is wrongly assumed that the oceans will become acidic, when in reality, ocean pH is never expected to fall below 7.0; i.e., the oceans are becoming

the seas are already between a ph of 7.5 and 8.5 without any chance of going below a ph of 7.

so anon and Mr Rabett will you join me in acknowledging that the seas will never become acidic,
as for arguing over whether a change in ph from 8.2 - 8.2 should be less base or increasing acidification, well that is up to the individual ,
Ken Cladeira uses both terms.

Freshwater acidification doesn't mean that freshwater is an acid:

So richy, will you agree with everyone else here that more acidic is correct and the more normal phrasing of even a alkaline solution that becomes "less base"?
PS do you not agree that fresh seawater if under extreme pressure and temperature will become actually acid as per discussion by arids.
PPS as for as for arguing over whether a change in ph from 8.2 - 8.2 should be less base or increasing acidification, well that is up to the individual, which you have insisted was not the case and that it was WRONG to use "more acidic", so please acknowledge your change in assertion.

anon,
well pointed out though the soil acidification was actually making the soil acidic down to a ph of 4. so perfectly fine to use that term.
when above 7 you are in alkaline territory and the term should be less base, but i am fine if you want you use the term acidification, just t be aware the seas will not become acidic.

I think best to use the words of Ken Caldeira , it has led you to be confused .
However, the term can also lead to CONFUSION
when it is wrongly assumed that the oceans will become acidic, when in reality, ocean pH is never expected to fall below 7.0; i.e., the oceans are becoming

Anon-101a here:
"well pointed out though the soil acidification was actually making the soil acidic down to a ph of 4."
So agricultural lime doesn't work unless the soil is ALREADY pH7.0 or less is your claim?
Because that's wrong.
If it isn't, then your claim about "it's pH is above 7.0, ergo cannot be acidification!" is bunkum.
And still note: acidification used in a paper in the 1980 when you claim it was "invented" in 2003.
Tell me, are you also claiming that 2003 is earlier than 1980.
And I note that you've elided COMPLETELY freshwater acidification.
What's the pH of freshwater, dearie?
Anon-101a here:
"I think best to use the words of Ken Caldeira ,"
I think that's rubbish. It has no bearing on your original claims, you've merely morphed your claim into something else and are now pretending that somehow Ken's words support your claims will stop anyone noticing that you yourself now rescind your claims, but insist that it's still only you that is right.
This is delusional.
well let's make this simple for you,
if you want to use the term acidification then absolutely use that term. But the seas are between 7.5 which is alkaline and 8.5 which is alkaline and not expected to go below 7 which is neutral.
If Ken Caldeira was not the first to use the term acidification then i am fine with that but he is generally known as the fist person to use the term specifically for the oceans.
Just be aware the seas will never become acidic,
at the moment the seas are between a ph of 7.5 and 8.5 naturally which is quite a range though a change of 8.2 - 8.1 through acidification has been bandied around, whatever even at 7.5 the seas are alkaline and in a stable state as mentioned previously in one of my earlier comments
Anon-101a here:
"well let's make this simple for you,"
The problem isn't that you're being too smart. Quite the opposite in fact.
The problem is you're wrong, have changed your claims, and have elided the fact of your change of stance to retain your claims that everyone else is still wrong.
You claimed ph drop from 8.2 to 8.1 is not getting more acidic. Now you claim it is "up to the individual". Most individuals claim "more acidic".
You then claimed Ken invented the term acidification in 2003, when this was false, and then skipped past it to go "Oooh, soil! Can be pH4.0! That's acid!" when that's neither the point nor actually true (as in "the whole truth"). Again eliding that freshwater acidification doesn't mean pH4.0. And ignoring that acidification of soil does not start from pH7.0, else lime would not be added nor acidic soils exist since they'd start from a non acid loam and become acidic from leeching soils.
And you still insist that somehow Ken's words make you right when they do not.
Farcical in its delusion.
For a conversation over rather basic terms, it is certainly becoming rather acerbic. One might even make a case that the dialog is trending toward the downright vitriolic.
I prefer the less technical but nevertheless accurate term "debased."
Anon-101a here:
you can bang on about pH of 7.0 and less being acid, but that doesn't say that going from 8.2 to 8.1 is not becoming more acid.
It is.
Your incapacity to see the irrelevance is why you're correctly claimed to be a delusional freak.
i am happy for you to use that term though remember 8.1 is heavily alkaline!
the problems for measuring the seas for a ph level is the following
The effect of solar radiation on pH is twofold: it
promotes photosynthesis and increases surface tempera-
tures, both of which decrease the amount of free carbonic
acid and consequently raise the pH (Skirrow 1965; Wetzel
1983). For example, at a depth of 23 m in the Beaufort
Sea, an average pH of 7.79 was recorded, whereas surface
pH measurements averaged 8.1content),

Richard, of course, is nitpicking over standard chemistry terminology because he wants people to believe that if ocean acidification doesn't actually cause the ocean's pH to drop below 7, then it is harmless.
Which is, of course, totally stupid, but we all recognize that he is, right?

A lot of scientific jargon causes confusion amongst those unfamiliar with the field.
BFD.
The general public doesn't need to know of the pH levels are going to be pH 7.2, 7.0, or 6.8.
The general public is interested in what effect ocean acidification will have, and this can be communicated to lay people without reference to specific specific pH values.
I think we all know that you believe that since pH levels will still be above 7.0 that ocean acidification isn't really a problem, and that scientists are intentionally using "confusing" language to promote the CAGW fraud on unsuspecting people who need to be rescued by modern-day Galileo's like you ...
That, after all, is the only reason for you to bitch about standard chemistry jargon, and to insist that the term was "invented" by Caldeira (in order to sensationalize results and push the CAGW agenda, right?)
i see so it will be easy for you to answer the following
are the seas acidic now or will they ever be?
richard:
"are the seas acidic now or will they ever be?"
I could easily, if I wanted to, but it is irrelevant.
Your question confirms my suspicion, though. You think this jargon, around for decades, was invented by Caldeira et al to hoodwink the public and to make CO2-driven ocean acidification look harmful when actually it won't be bad because, well, because you don't understand science.
When the weatherman says "today's high was 0F, but temps are warming, and tomorrow's high will be 15F", is she lying because it will still be cold despite warming?
Do you call the TV station accusing them of meteorological fraud because they didn't say "less colding"?
," is she lying because it will still be cold despite warming?"
i agree, as you illustrate with the weather( it will still be cold) you realize that even with a 0.7 unit change in the ph, the seas will still be alkaline!!
"I could easily, if I wanted to, but it is irrelevant"
you just did!!
well done
Richard:
"i agree, as you illustrate with the weather( it will still be cold) you realize that even with a 0.7 unit change in the ph, the seas will still be alkaline!!"
And we still have winter despite global warming.
WTF is your point?
At this point I have to assume you're not sharing your last name because whatever institution you've been committed to only issues name tags with first names.
In other words, you are nuts, pure and simple.
Oceanographers studying ocean acidification have never claimed it will lead to oceans actually becoming acid. Never. We all know that. Lower pH will be dangerous to a wide variety of marine organisms, we all know that, too. Ocean acidification is the proper term, we all know that, too.
You'll a drool-spittled idiot, and we all have learned that, too, albeit a bit more recently due to not having had the mispleasure of meeting you decades ago.
"Oceanographers studying ocean acidification have never claimed it will lead to oceans actually becoming acid"
not sure what the point of using the term acidification is for then as whatever happens the seas will be always be alkaline,
so where does that leave us, well we know the seas are stable at between an alkaline ph of 7.5 and 8.5 and we know that
that the seas will never go below the neutral state of a ph of 7. so then we look at the paper of
Ken Caldeira and he states that the seas will never become acidic and more importantly !!
"there may be a pH decrease of ~0.7 units"
"may" sounds uncertain, so not sure what you are worried about.
so now I will word it and i will be correct in saying it
"there may be a decrease in alkalinity of the seas"
not so scary is it!!!!

Richard:
Thank you for proving my point. We now return you to your regularly scheduled medications …
your point being?
"there may be a decrease in alkaninity?
so far nothing has happened that illustrates there is a problem.
the seas are stable at a ph of 7.5 - 8.5.
and we know there are changes in the ph of the seas within 23m of the surface - from 8.1 to 7.9 .
So nothing to be alarmed about. The ph of the seas fluctuates quite naturally.
as for the meds, will you be contacting the following suggesting they take them.
let me see now,
I quoted in comments above,
the EPA -rules and regulations of coastal waters
Caldeira and Wickett,
2005)" - who first used the term acidification of the seas but point out the correct term is "less base"
and

you in turn quoted nothing except to bang on about the term acidification , oh and meds,
you need to do better than that!!!
pH does not measure alkalinity, sweetie, it measures the concentration of hydrogen ions in a solution, and thus acidity. Regardless of the starting pH level, increasing the H+ concentration lowers pH, which is defined as acidification. Every chemist on the planet knows that.
Rome continues to heat up while fools with agenda fiddle with semantics.
It's all very well for people to argue about this being an issue of terminology for chemists who are, be honest, a very very small proportion of the population.
Life would be a lot easier if we referred to the language of people who are a much larger proportion of the population, gardeners and farmers and other agricultural/ horticultural folks. If you watch a very few hours of television on these topics, you'd know that "acidification" is very common terminology regardless of measured pH.
MinniesMum
richard shows his complete ignorance of chemistry especially as it relates to pH. He thinks that adding CO2 to sea water will reduce its "alkalinity". That is complete rubbish, adding CO2 to sea water will reduce its pH i.e. make it more acidic but it wil not reduce alkalinity.
Alkalinity has got nothing to do with the pH of a solution. Alkalinity is measured in “mg/L as CaCO3″. Incidentally, addition of CO2 to water does not change the alkalinity but does change the pH.
Thread has become rather caustic.
Maybe bitter.
yes the ph can be low with a high alkininity,
but
"make it more acidic"
yes but anything above 7 is alkaline!!!
and as i keep repeating the seas are stable between an alkaline ph of 7.5 and 8.5 with the seas never ever ever going below a ph of 7,
there is no problem with the ph of the seas.
So sure if it makes you feel better the seas are stable between a ph of 8.5and a lower ph, where it is more acidic, a ph of 7.5 though this is still actually alkaline ,
there are you happy,
or as i posted above in the bEaufort sea the surface water has a ph of 8.1 and 23m lower where it is more acidica ph of 7.79, though as we know this is still alkaline,
now then guys tell me what you are worried about
or lets turn to the EPA regulations up to 19 kilometers
off shore the US they allow a ph of between an acidic ph of 6 up to an alkaline 8.5.
though what astounds me is the the guy who actually used the term acidification for the first time in a paper about the ph of the seas spells it out so clearly.
I repeat again,
"However, the term can also lead to CONFUSION
when it is wrongly assumed that the oceans will become acidic, when in reality, ocean pH is never expected to fall below 7.0; i.e., the oceans are becoming
less basic, but not acidic. Such a phenomenon could
only occur in the unlikely event that CO2 emissions
reach more than 10,000 Pg C (Caldeira and Wickett,

anon,
really what is your point,
i told you , you can use the term if you like but so what are you trying to prove using that term, what does it mean, at any point wherever you stop on the ph scale down to a neutral ph of 7 the seas are alkaline.
the seas will never be acidic,
they are at a stable ph of between 7.5 and 8.5
even the guy who used the term acidification for the first time says it leads to confusion , he even says the seas MAY decrease by 0.7 , decrease from what , he never says, was he using 8.5, 8.4. 8.3. as his starting point, as the seas are STABLE between 7.5 - 8.5 his views are rather limited.

pH
pH is a measure of the acidity or alkalinity of a substance and is one of the stable measurements in seawater. Ocean water has an excellent buffering system with the interaction of carbon dioxide and water so that it is generally always at a pH of 7.5 to 8.5. Neutral water is a pH of 7 while acidic substances are less than 7 (down to 1, which is highly acidic) and alkaline substances are more than 7 (up to 14, which is highly alkaline). Anything either highly acid or alkaline would kill marine life but the oceans are very stable with regard to pH. If seawater was out of normal range (7.5-8.5) then something would be horribly wrong.

What? The wrong words?
You've consistently claimed that the ocean cannot become acid, such as when you claimed the paper on soil acidification supported your claims because acid soils can have a pH below 4.0. The ONLY WAY that could be the case is if it had to be acid before it could be acidification, and the ONLY WAY that could make "ocean acidification isn't happening" true is if you're claiming that the process cannot happen until it's acid.
Just because your claims rest on a causal logical link (that is incorrect in this case) that you don't explicitly state doesn't mean your claims do not rest on that causal logical link.
You've been wrong
a) the ocean is becoming more acid because we're adding carbon to it
b) acidification doesn't require being acid at the end of the change to be acidification
c) acidification was not invented in 2003
d) more basic would be correct if you added a base to the ocean, which we aren't.
e) "Ocean acidification has changed pH from about 8.2 to 8.1, so far" was never said in the comment thread
but your "best answer" to your failures are
a) "I HAZ PATENCE!"

This same terminology is used when measuring pH. In a process called “titration”, you measure how much acid it takes to neutralize an unknown basic solution. If you add too much acid, the pH drops below 7.0 and the mixture becomes acidic. Add too little acid, and the mixture remains basic. Your goal in titration is to add just enough acid to neutralize the basic solution. Then you can tell how alkaline it was, by the amount of acid that it took to neutralize the basic solution.

We already know the solution we're putting the acid into: water.
And it's not alkaline or base, else adding alkaline or a base to water would not make it less acidic.

so do you see a slight problem there in your thinking,
how does something actually become more acidic until it reaches a neutral state!!
remember a ph of 7 is neither acidic or Alkaline

imagine burning all the fossil fuels in the world will not make the oceans acidic but might make them get to a neutral state,

Scallops, co2 or just plain pollution!!
Canada flushes some 200 billion liters of raw sewage directly into natural waterways every year, from the St. Lawrence River to the Strait of Juan de Fuca and the Pacific Ocean. That’s only a fraction of the three trillion liters of sewage Canadians produce annually—about 6 percent, in fact—but it’s still enough to fill more than 40,000 Olympic-sized swimming pools.
A Dangerous Brew
According to Macleans, Canada’s leading news magazine, the sewage is a mixture of water, human waste, microorganisms, toxic chemicals, heavy metals, excreted pharmaceuticals and, potentially, pathogens such as cholera, typhoid and hepatitis B.
"It is widely recognized that inadequate or no waste water treatment have negative impact on aquatic life, human uses of water, fisheries and human health,” Environment Canada told Macleans. “Therefore it is unacceptable and shortsighted not to maintain and upgrade infrastructure."
Richard, you did not answer my question.
The EPA guidelines refer to SURFACE water and are set to allow for the natural and human-pollution related pH of rain, which may vary considerably.
Also, a pH of 7.5 allows different life than that of 8.5. You might want to see what a few degrees of annual difference in average temperature does to biotopes, despite the enormously larger intra-annual variation in temperature. Now tell us how the biotopes that work best at pH 8.0 move to the regions where the pH used to be 8.5, but is now 8.0.
Finally, please tell us what special expertise you bring that allows you to contradict the scientists who work on this topic on a daily basis for decades.

I couldnt' be bothered to read it all, but is Richard an illiterate (i.e. doesn't understand that the -ation ending means becoming, moving towards) or anti-science (i.e. denying that such changes in pH as we are experiencing and will see will be a problem)?
illiterate or anti-science
He's an inventor! Or more properly, an inventionator.

I stopped responding because it became clear that it is the latter: he doesn't think such changes are a problem and that the term "acidification" is being fraudulently used to scare people, not because it is jargon.
He's not only an inventor with a patent, he's also an inventor of sockpuppets.
i.e., Wabbett, he's using "rspung" in one thread and "richard" here. if you don't have rules against sockpuppets this would be a good time to implement one and ban both …
i have used and quoted as a basis for my comments above.

the replies from anon and his other names regarding PH of any substance have so far come from a piece about soil Ph and a piece about blood ph.
1/ 10 you must try harder
"Also, a pH of 7.5 allows different life than that of 8.5"
and yet this is the stable state of the seas with a ph of 8 being an average.

7.5 – 8.5, that is quite a range.

unless we think NOAA are cranks for stating this,

We don't.
However, this has nothing to do with your whining streak on here, dearie.
Anon-101a:
"i have used and quoted as a basis for my comments above."
WRONG.
Lies by omission are still lies, dearie.
Anon-101a here:
Given your hysteric posts to hide it, this question must have you REALLY frightened, dearie:
What is it called when blood pH levels drop below pH7.35?
what is it called when the range of ph of the seas are stable between 7.5 and 8.5 now and into the future as quoted from NOAA and the Canadian water board.
Anon-101a here:
"Tell that to those farming calcium carbonate shell marine species, dear patent-holding chemical engineer."
Remember that AIG have several PhDs in geology on their staff.
Remember too that his "invention" is merely a process patent, the most worthless kind, and merely one that extends the work of others who did some ACTUAL innovation.
His is the chemistry equivalent of the AUS patent on "Swinging in a circular pattern on a swing".
In short, his degree is likely of no actual utility to determining his ability.
Meanwhile his "theory" that acidification was invented in 2003, that it's the wrong term unless the mix ends acid and the theory that varying ph by 1.0 is "stable" indicate most strongly that he has absolutely no clue what's going on in chemistry.
And most tellingly of all, he's unable to answer the question of what a blood pH below 7.35 is called.
Why?
The same reason the PhDs at AIG insist that YEC is absolutely proven science.
Anon-101a here:
"what is it called when the range of ph of the seas are stable between 7.5 and 8."
pH variation isn't stability, dearest.
what is it called when it will take 600 years for the ph of the seas to be 7.49, a fraction below the stable 7.5 and 8.5 we have today as quoted by NOAA.
what is it called when we know the seas will never become acidic as quoted by
— Christopher L. Sabine, Supervisory Oceanographer, NOAA Pacific Marine
Environmental Laboratory, USA
but anon do carry on and ask me questions about blood and the soil.
Anon-101a here:
"what is it called when it will take 600 years for the ph of the seas to be 7.49"
A prediction.
What is it called when someone asks a question of no relevance?
A diversion, dearie.
The seas are not stable, they are more acidic, they are becoming more acidic due to human release of fossil carbon. Acidification was not invented in 2003, the normal term for the process is acidification.
Live with it.
Anon-101a here:
"what is it called when we know the seas will never become acidic as quoted by"
A failure to understand what you did.
What is it called when blood pH is below 7.35?
Anon-101a here:
Dearie, until you take notice of your questions being answered, no questions of yours will be answered until you agree to answer a few of everyone else's.
I am afraid richard will never ever understand anything that does not fit what he has already decided must be true. Acidification? Wrong term, because he has decided it sounds "alarming". pH of the oceans between 7.5 and 8.5? Then a drop of a few units does not matter!.
The illogic in his thinking will simply not get through. Ever. Complete waste of time, just as the various attempts at wottsupwiththatblog/andthentheresphysics at educating him. Sigh.

pH of the oceans [vary] between 7.5 and 8.5? = Stable!
FTFY.
I wonder if dicky here is Oprah's dietician: "Don't worry, Ophrah, your body weight is stable between 8st and 20st!"
yep the seas are stable between the ph of 7.5 and 8.5
sort of like the blood but with more latitude, the normal pH of arterial blood lies between 7.35 and 7.50
yes stable between the ph of 7.5 and 8.5 ,
sort of like blood but with more latitude,
the normal pH of arterial blood lies between 7.35 and 7.50
Anon-101a here:
A number that varies is not stable, dearie.
And, like oceans, blood doesn't have to be acid to become acidic.
Anon-101a here:
Tell us all, o fount of all f-wittery, what does "yep the seas vary between the ph of 7.5 and 8.5 " have to do with "Ocean acidification has changed pH from about 8.2 to 8.1, so far."
?
would you say the blood is stable between the normal 7.35 and 7.50.
Ocean acidification has changed pH from about 8.2 to 8.1, so far."
and?
the seas are stable between 7.5 and 8.5 and will take another 600 years to get to a ph of 7.49.
the beufort sea has a surface ph of 8.1 and 23 meters down has a ph of 7.79 so what about 8.1!
Anon-101a here:
"would you say the blood is stable between the normal 7.35 and 7.50."
I refer the right dishonourable shithead to my earlier comment.
Anon-101a here:
"Ocean acidification has changed pH from about 8.2 to 8.1, so far."
and?"
Yes.
And?
And so what does "yep the seas vary between the ph of 7.5 and 8.5 " have to do with "Ocean acidification has changed pH from about 8.2 to 8.1, so far."
Anon-101a here:
dicky #1:"what is it called when the range of ph of the seas [vary] between 7.5 and 8."
dicky #2: "what is it called when it will take 600 years for the ph of the seas to be 7.49"
Dicky dear, is 7.49 within the range 7.5 and 8?
Do you even know enough maths to be able to answer?
My prediction: No.
don't worry, the canadian marine authorities state marine waters should fall between a ph of 7- 8.7
