WUWT: Claim: New Global Maps Detail Human-Caused Ocean Acidification

Do they avoid the salinity level deliberately? When the salinity level drops, then the water becomes more acidic or more accurately less alkaline … The water in the northern regionhave normally low salinity, so …

Watts Up With That?

In northern winter, the Bering Sea, dividing Alaska and Siberia, becomes the most acidic region on earth (in purple) as shown in this February 2005 acidity map in pH scale. Temperate oceans are less acidic. The equatorial Pacific is left blank due to its high variability around El Niño and La Niña events. (Takahashi)A team of scientists has published the most comprehensive picture yet of how acidity levels vary across the world’s oceans, providing a benchmark for years to come as enormous amounts of human-caused carbon emissions continue to wind up at sea.

“We have established a global standard for future changes to be measured,” said Taro Takahashi, a geochemist at Columbia’s Lamont-Doherty Earth Observatory who published the maps with his colleagues in the August issue of the journal Marine Chemistry. The maps provide a monthly look at how ocean acidity rises and falls by season and geographic location, along…
