Satellite Remote Sensing & Ocean-Atmosphere Interactions
Dr. Walker’s research centers on satellite remote sensing of Gulf Coast ocean dynamics, from Loop Current eddies to hurricane–ocean interactions. She fuses real-time multisensor imagery, field data, and circulation models at LSU’s Earth Scan Laboratory to sharpen hurricane intensity forecasts, track oil spills, and guide coastal management.

The Gulf of Mexico can be a complicated body of water. We know the water is hot but there are various currents and eddies that are sometimes cold. All of these can have big impacts on hurricanes both good and bad. Dr. Nan Walker is a James P. Morgan Distinguished Professor of Coastal Studies in the Department of Oceanography & Coastal Sciences at Louisiana State University. She is also Director of LSU’S Earth Scan Laboratory. Her areas of expertise include physical oceanography, satellite oceanography, air-sea interactions and tropical cyclone intensities, the Gulf of Mexico Loop Current and eddy circulations.

Impacts of a major Mississippi River freshwater diversion on suspended sediment plume kinematics in lake Pontchartrain, a semi-enclosed Gulf of Mexico Estuary
Estuaries and Coasts2021
MODIS satellite imagery and in situ water measurements were used to quantify inorganic sediment concentration (ISC) and, subsequently, sediment plume motion and evolution during the 2016 diversion of the Mississippi River through the Bonnet Carré Spillway (BCS) within Lake Pontchartrain (LP) estuary in Louisiana, USA. Satellite images revealed that sediment plume areal distribution was closely linked to BCS discharge rate. The plume flowed eastward along the southern LP coastline at an average speed of ~ 0.3 m s−1 during the first week of the event and attained its maximum areal extent (~ 1117 km2; 68% of the total LP area) on 23 January.
