Sentences with phrase «ocean reservoir»

This deep ocean reservoir exchanges carbon with the surface on time scales of hundreds of years.

My question is, what is the average time for the excess atmospheric CO2 produced by burning fossil fuels to mix into the deep ocean reservoir.

Co-author Hayley Hung, a scientist with Environment Canada's Air Quality Division who studies toxic organic pollutants in the Arctic, said that in recent years, researchers had posited that warmer conditions would liberate POPs stored in land, ice and ocean reservoirs back into the atmosphere.

Some deep ocean reservoirs peaked after that point.

Moreover, the radiocarbon community has suggested the use of local calibration curves to better account for regional MRE offsets in the heterogeneous ocean reservoir, but a reasonable method for their construction has not yet been proposed.

It has become clear over the past few years that the importance of Southern Ocean upwelling for our understanding of climate rivals that of North Atlantic downwelling, because it controls the rate at which ocean reservoirs of heat and carbon communicate with the surface.

The estimated uptake timescales are within the range he reports for his data - driven calculation, 50 years or so, even though the mean uptake time of the ocean reservoirs in that model, weighted by their sizes, is 600 years.

... not intended to suggest that the heat capacity exchange / transfer / transport rates used are a realistic representation of actual ocean circulation, although from what little I know, it could be a step in that general direction from using one upper and one deep ocean reservoir.

The ocean reservoir stored 155 ± 30 PgC.

The size of the deep ocean reservoir is big enough that it could buy us a few decades.

The emissions and their partitioning only include the fluxes that have changed since 1750, and not the natural CO2 fluxes (e.g., atmospheric CO2 uptake from weathering, outgassing of CO2 from lakes and rivers, and outgassing of CO2 by the ocean from carbon delivered by rivers) between the atmosphere, land and ocean reservoirs that existed before that time and still exist today.
