Research Interests

Dr. Friedrichs uses numerical models to better understand how and why primary production, and the associated export of carbon, varies among diverse marine environments. Her research involves the application of a number of different types of marine ecosystem models in combination with data assimilation and remotely-sensed ocean color data to study a variety of interdisciplinary oceanographic questions of direct marine biogeochemical relevance.
