Bio: Dr. Margaret (Meg) Estapa earned a BA in Chemistry from Carleton College (Northfield, MN, USA) in 2001 and a Ph.D. in Oceanography from the University of Maine in 2011. From 2011-2013 she was a Postdoctoral Scholar at the Woods Hole Oceanographic Institution where she studied variability in the biological carbon pump at short spatiotemporal scales and worked on new methods for quantifying the strength of the pump using bio-optical sensors and autonomous profiling floats. From 2014-2020, she was an Assistant Professor of Geosciences at Skidmore College, while also serving as a member of the Science Team for NASA’s Export Processes in the Ocean from RemoTe Sensing (EXPORTS) program and as lead PI for the sediment trap observations. In 2020 she moved to the University of Maine where she is the Libra Assistant Professor of Chemical Oceanography. Dr. Estapa’s broad research focus is on the chemical transformations and physical fluxes of naturally-occurring particles in the ocean, with an emphasis on rapid processes that alter these particles as they cross major earth system boundaries—e.g., into the ocean across coastlines, downward from the sunlit surface ocean through the “twilight zone”, and upward from the bottom through sediment resuspension, or through hydrothermal vents into cold, deep waters. The unambiguous observation of these processes in the ocean requires measurements at spatiotemporal resolutions that are sufficient to separate physical gradients, biological processes, and chemical transformations of particles. Dr. Estapa’s projects involve the development of novel applications for in situ, optical particle sensors; process models incorporating the results of laboratory experiments under controlled conditions; interdisciplinary field observations; and synoptic, remote-sensing observations.
