Meg Estapa is a biogeochemical oceanographer who uses sediment traps, satellite ocean color data, and in situ optical sensors to study the ocean’s biological carbon pump.  Her interests include the controls on small-scale variations in the sinking flux of particulate carbon out of the surface layer of the ocean – an important, but hard-to-predict part of the ocean’s carbon cycle.  Dr. Estapa’s work on observations of the biological carbon pump started at Woods Hole Oceanographic Institution, where she most recently was a postdoctoral researcher.  She is currently an Assistant Professor of Geosciences at Skidmore College in Saratoga Springs, NY, whre she teaches courses in oceanography and remote sensing of the Earth.
