Covering about 71% of the planet's surface, the world's oceans play a fundamental role in shaping climate zones we see on land. This is a good reason to measure various parameters of the different oceans and determine where these parameters were in the past and where they will be in the future.
Of the numerous risible calamities to be associated with the climate change science, "Ocean Acidification" must be one of the poorest studied and wildly narrated of climate change science topics.
As you can see, the IPCC WGI AR5 has rolled out the High Certainty Welcome Wagon concerning this topic. With such a high degree of certainty, one would think that there would be a large amount of observational data to accompany such a judgement. Think again.
From Richard Telford's blog is a comment by Latimer Alder that is quite an eye opener:
There are only these three (BATS, HOTS and ESTOC) long term datasets, and only Bermuda (BATS) goes back to 1983. An IPCC observational Working Group I reports, with High Certainty the sum of all data:
Verified with this concluding Discussion remark in Hofmann et.al. (2011):
In summary, together, these pH time series create a compelling argument for the collection of more continuous data of this kind. Specifically, these data represent a critical step in understanding the consequences of ocean change: the linkage of present-day pH exposures to organismal tolerance and how this translates into ecological change in marine ecosystems ,. Long-term datasets exist, but many are in open-ocean locations (HOTS, BATS, ESTOC) and do not capture environmental variation in the coastal marine habitats that are of such critical ecological and economic value . Additionally, they often do not capture changes in pH at physiologically relevant timescales since they are limited by ship-board sampling frequencies.
Obviously, all the other datasets are modeled somewhere else.
Special thanks to Latimer Alder for pointing this comment out.
