The RATS did it, wethole. This guy and his friends pissed in the water:
Crosstard, you know we aren't going to have oyster larvae, for awhile, in the Northern hemisphere, and the South is gathering data, but they should have a report, in our Fall. Why don't you try to be more like this guy, while we wait for fresh reports:
Here's something I didn't know. The water which upwells is basically the same water, which was at the surface, 50 years ago. So as the upwelling cycle matures, the water will be even more acidic, but it will tend to be from half-century old assimilation, of atmospheric carbon:
Along the Pacific Northwest coast, that ongoing process is intensified by a natural ocean circulation pattern, the seasonal upwelling that pulls water from the deep ocean onto the continental shelf each spring. According to a 2008 study by researchers at the National Oceanic and Atmospheric Administration, the water stirred up by that natural upwelling has reached levels of acidity that scientists once believed wouldn't occur until 2050.
But that fast-forward is also a look backward. The deep ocean water stirred by the annual upwelling is the surface water of 50 years ago, increasingly richer in CO2 as the proportion increased in the atmosphere.
Now, as that old water resurfaces, it is creating new problems for shellfish growers.
