It’s humbling going out to sea and realizing everything you can see from the ship is but a single data point." Zachary Erickson is an oceanographer at Goddard. He studies how ocean life takes in carbon dioxide and how that process affects Earth's climate. Erickson uses satellite images to track the movement of phytoplankton in the ocean, to gauge how these microscopically tiny plants absorb carbon. He would like to understand the potential benefits and risks of processes that look to the ocean to help address climate change. Image 1: Ocean color in the North Sea. The influence of physical motions on biology is obvious in the small-scale stirring of phytoplankton biomass (green colors). Credit: NASA/MODIS Aqua/Norman Kuring」2月25日 3時29分
