Sentences with phrase «through iron fertilization»

Far riskier is intentional acceleration of carbon dioxide removal by enhancing the biological uptake in the ocean through iron fertilization.

According to Ingall, removal of iron by diatom - dominated phytoplankton communities may dampen the intended outcome of enhanced carbon uptake through iron fertilization by reducing the productivity of other phytoplankton, which take up carbon dioxide more efficiently.

Not exact matches

Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient exported.

MIT's Sallie «Penny» Chisholm, one of the world's top biological oceanographers, finds the idea of geo - engineering the earth's atmosphere through oceanic iron fertilization to be anathema.

Following the SOFeX iron - fertilization experiment in the Southern Ocean, deep - diving Carbon Explorer floats continuously collected data for over a year, straight through the Antarctic winter.

A second general method for cooling the planet involves removing carbon dioxide (CO2) from the atmosphere, either via sequestration or CO2 capture, or possibly through ocean iron fertilization to promote the growth of CO2 - consuming algae.

Potential carbon dioxide (CO2) drawdown through dust - induced iron fertilization of ocean biota is restricted to high - nutrient, low - chlorophyll (HNLC) regions, mainly the Southern Ocean and northern Pacific where iron is the limiting micronutrient (6, 13).
