The Organic Carbon Cycle In The Arctic Ocean - tuareg.tk

is the arctic ocean a carbon sink national snow and ice - in a new study from mit dutkiewicz found that with decreased sea ice the arctic ocean is becoming more of a carbon sink the team of scientists modeled changes in arctic sea ice temperatures currents and flow of carbon from 1996 to 2007 and found the amount of carbon uptake in the arctic increased by one megaton each year, oceanography university of washington -
