Research Interests

Coastal organic carbon cycling - Blake's research focuses on carbon cycling in the coastal ocean. He uses process-based experiments to construct and inform biogeochemical models to investigate carbon cycling on multiple time and space skills. He has ongoing research in the Chesapeake Bay estimating organic matter cycling and fluxes in a tidal marsh influenced estuary, focusing on the export of dissolved organic matter from marshes and the role tidal marshes play in estuarine biogeochemistry. Blake's current focus has shifted to the Arctic where he will take his skills developed in the work in the Chesapeake Bay and apply them to study the organic carbon dynamics of the Yukon River plume.

Biogeochemical model development - Incorporating new and important processes into biogeochemical models requires precise field and laboratory measurements to inform mathematical models. Part of his work focuses on identifying current gaps in the biogeochemical modeling frameworks in use. Once identified, targeted sampling and experiments can build data sets that can be used to build a mathematical model. These mathematical models can be implemented on multiple scales to quantify the importance of any given process to elemental cycling as a whole.


Blake Clark is an early career scientist with a focus on land-estuary-ocean biogeochemistry and carbon cycling. He completed his PhD in 2019 at the University of Maryland Center for Environmental Science, Horn Point Lab under the advice of Dr. Raleigh Hood. There, he worked on developing and applying a model that represented the processes of tidal inundation and marsh-estuary linkages and organic matter cycling. Upon graduation in 2019, he began a NASA Postdoctoral Program (NPP) fellowship at Goddard in the Ocean Ecology Lab with Antonio Mannino as his advisor. Dr. Clark's research focus shifted towards modeling and remote sensing of the coastal Arctic. He is now an associate scientist with USRA/GESTAR and hopes to continue advancing the understanding of coastal environments and how the land and ocean carbon and nutrient cycles are linked via rivers and estuaries.
