What’s the opposite called — alkalinisation if you’re old-school or basicisation (basicise?) if you’re younger?

There is some good reliable data at Sea Friends, a New Zealand site. Among much else, there is this (summarised):

Ocean pH occurs in a range from about 7.8 to 8.3. The lowest pH occurs in upwelling areas and the highest pH occurs in the centres of ocean gyres (rotating areas). It would be difficult to calculate the ‘average’ pH for the oceans, let alone whether they have become more or less acidic. Note that upwelling areas are more acidic because high-CO2 bottom water surfaces, warms up and makes CO2 more readily available, a bonus for photosynthesis by marine plankton.

They say there are few time series of ocean acidity, so few conclusions should be drawn, especially about the cause of any increase in acidity in a region. Natural variability is regular and fairly large. There appears to be a maximum pH, as there are no excursions to pH higher than about 8.15, but frequent excursions to lower pH levels such as 8.02.

There are some interesting graphs.

Careful if you go swimming in the ocean this summer then

Acidification means, becomes more acidic, i.e the pH of the oceans is reducing. The pH scale is a measure of hydrogen ion concentration in a solution. More acidic means more hydrogen ions.

go figure

FYI: Samoth’s, or Thomas’ last name is most probably Palm. He’s nicked TTTP by Swedish blog-writers, which spells out: ‘Thomas The Tippingpoint Palm’ and he is truly making full cred of that nick. His style of writing/’discussing’(?) and general appearance [here] are identical to what can be seen/read [though in Swedish...;) ] at: http://www.theclimatescam.se – there, though, he is Thomas.

“It is a VERY interesting development given the position of the GISS ModelE in the simulation arena i.e I think there is some desperation here by GISS.

ModelE is a “conventional” model that is in danger of becoming on the outer in comparison to newer generation models that incorporate Cloud Resolving Models (CRM’s)to such an extent that it may be irrelevant or cause a rift in the “narrative”.

I see some strategic positioning to deflect attention from this and to try to discredit the opposition. There is even in-house NASA rivalry at play.”

I asked Richard S. Courtney to comment on my analysis:-

My question:

Is my analysis way off?

His answer:

It is spot on and not “way off”

Chris, the PH scale runs 0 – 14, 7 is neutral, 7 -14 is alkaline, 0 – 7 is acid, the ocean is 8+

Go figger!

Try doing a search on ocean acidification. The CO2 cycle is well understood. The PH of the oceans are significantly changing because of increased atmospheric CO2. The reduction in PH is threatening many species of shellfish. Setting aside AGW – which should be of serious concern – Ocean acidification is also a serious threat to sea life.

Thomas I do resent being assessed as someone who is ‘desperately fishing for confirmations to … preconceived ideas’ by someone not prepared to provide his full name;
Are you prepared to provide however the basis upon which you made the assumption that I am ‘desperately fishing for confirmations to … preconceived ideas’?
It’s a bit of a generalisation from someone with a physics degree.

“Rebuttals” from either Sceptical Science or RealClimate (probably the two most ill-named site on the internet) don’t hold much credibility for me.

The latter was set up partly by one William Connelly, now topic banned from Wikipedia for overly biasing climate pages in favour of his own views.

It’s hardly a recomendation for impartiality is it?
