Sentences with phrase «by ocean alkalinity»

Modulated by ocean alkalinity, at 400 ppm atmospheric CO2, surface seawater declines to pH 8.2 or 8.1 (blue curve).

Not exact matches

The CDR potential and possible environmental side effects are estimated for various COA deployment scenarios, assuming olivine as the alkalinity source in ice ‐ free coastal waters (about 8.6 % of the global ocean's surface area), with dissolution rates being a function of grain size, ambient seawater temperature, and pH. Our results indicate that for a large ‐ enough olivine deployment of small ‐ enough grain sizes (10 µm), atmospheric CO2 could be reduced by more than 800 GtC by the year 2100.

So perhaps there could be a thread on effects of declining ocean alkalinity, where people would be asked to back up whatever scientific view they take by citing a published paper?

The last time I looked, the oceans were pronouncedly alkaline, and even the mad IPCC says the acid - base balance has been altered by only 0.1 acid / base units in the direction of slightly reduced alkalinity.

Climate engineering by enhancement of ocean alkalinity: impacts on the Earth system and a comparison with solar radiation management.

The increased carbon dioxide absorbed by the oceans is being recorded as a measured decrease in ocean alkalinity.
