photo: Karen MarksKaren Marks has worked as a Geophysicist since 1990 at the NOAA Laboratory for Satellite Altimetry of the U.S. National Oceanic and Atmospheric Administration in Silver Spring, Maryland, USA. She received a B.S. in Geology from the University of Florida, an M.S. in Geophysics from Boston College, and a Ph.D. in Geophysics from the University of Houston, with a dissertation on the geophysics of the Australian-Antarctic Discordance Zone. Her current research includes analyzing errors in altimetric bathymetric models, evaluating bathymetric datasets for United Nations Law of the Sea applications, and the detection of seamounts in satellite gravity and satellite-derived bathymetry. Her research also encompasses marine tectonic and geodynamic applications of satellite altimetry with emphasis on plate tectonic histories and seafloor spreading. She advises the General Bathymetric Charts of the Oceans (GEBCO) Technical Sub-Committee on Ocean Mapping (TSCOM).
