Overview
My research focuses on studying the distributions, sources and sinks of dissolved (DOM) and particulate organic matter (POM) in the ocean to enhance our understanding of carbon cycling, especially in the coastal zone. A primary objective is to link the optical properties of DOM and POM (such as absorption, scattering and fluorescence) to carbon in the ocean to be able to examine the carbon cycle using ocean color satellite measurements. Dissolved organic carbon (DOC) comprises nearly all (>97%) of the organic carbon in the ocean and constitutes one of the largest pools of organic carbon in the biosphere (equivalent to carbon dioxide in the atmosphere). Studying the distribution, sources and sinks of DOC and particulate carbon within the ocean is essential to understanding the Earth and ecosystem variability.
Current Research Projects
DYNAMICS OF COASTAL OCEAN DISSOLVED ORGANIC MATTER
Supported by NASA’s New Investigator Program
The main objective of this project is to examine the sources (terrigenous and algal) and sinks (photo-oxidation and microbial mineralization) of dissolved organic matter (DOM) and the distribution of dissolved organic carbon (DOC) in coastal ocean waters of the Chesapeake Mid-Atlantic Bight (CMAB), which encompasses the continental margin region off the coast of Virginia, Maryland and Delaware. Our approach includes using ocean color satellite data products (from MODIS and SeaWiFS), field measurements from the ocean, and laboratory experiments. Exploring these issues will improve our models of the carbon cycle and help us better predict how natural processes and anthropogenic activity impact the ocean and coastal ecosystems.
EASTERN U.S. CONTINENTAL SHELF CARBON BUDGET: MODELING, DATA ASSIMILATION, AND ANALYSIS
Supported by NASA’s Interdisciplinary Science Program
The overall goal of this project is to develop carbon budgets for coastal ocean waters of the Mid-Atlantic Bight (MAB) and South Atlantic Bight (SAB) of the east coast of the United State (from Cape Cod, Massachusetts to Cape Canaveral, Florida).
