Getting a Grip on Biogeochemistry

MIT/WHOI Joint Program student Louie Wurch (top) and chemistry research assistant Justin Ossolinski recover a conductivity-temperature-depth (CTD) rosette from the Sargasso Sea in April 2008. Marine chemist Ben Van Mooy led the interdisciplinary research cruise on the Oceanus, which included scientists working on the biogeochemistry of the region; specifically, how phosphorus and other nutrients affect and limit the growth of phytoplankton in the ocean.
