Maria Liste has joined the U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts. Liste will work collaboratively to apply a fully three-dimensional coupled modeling system to investigate how forces created at the seabed by currents and waves mobilize and transport sediment across the coastal region and inner continental shelf offshore of Fire Island, New York. The inner continental shelf at this location is characterized by a series of large shoreface-connected sand ridges. Recent geophysical investigations have identified mobility of these ridge features, and locations of sediment deposition on the inner continental  shelf. Liste will conduct targeted numerical experiments to study the hydrodynamic forcings and processes that transport sediment in this region. Results will help scientists to understand the larger coastal response to storms, including the response to Hurricane Sandy in 2012.

Originally from Spain, Liste studied oceanography and earned her Ph.D. at the University of Cantabria in Santander, Spain. Her thesis research focused on ocean circulation patterns on the Spanish coastline to assess the probability that an oil spill would impact a certain area of the coast. Other previous experience includes working at University of Leuven (KU Leuven) in Belgium, where she studied river-plume dispersion in response to flash-flood events and improved models in fluid dynamics codes to better simulate deformation and flow of cohesive sediments.
