Research Interests

I am interested in factors that affect the distribution of phytoplankton in space and time. This work has focused on coccolithophores, which are one of the main sources of calcium carbonate in the global ocean, and a major source of light-scattering in the sea. More recently, we have focused on ocean acidification and its effects on coccolithophores. My studies have crossed interdisciplinary lines in five areas:

Biocalcification: My laboratory has been studying the factors which regulate biocalcification. This has involved considerable time at sea and in the laboratory. We are synthesizing surveys of calcification in the equatorial Pacific, Arabian Sea, North Atlantic, Patagonian Shelf, Gulf of Maine and the Southern Ocean.

Bio-optics: These studies have focused on the bio-optical impact of suspended calcite in seawater and remote sensing algorithms used to quantify calcium carbonate concentrations from space. Since 1998 we have maintained an active field program in the Gulf of Maine involving a comprehensive time series of hydrographic, biological, optical and chemical properties (the Gulf of Maine North Atlantic Time Series, or GNATS). We also have participated in the Atlantic Meridional Transect program between 2004-2016.

Ocean Color Algorithms for Satellite Remote Sensing of carbon production: My laboratory has maintained a long–standing interest on remote sensing algorithms for suspended calcium carbonate (aka particulate inorganic carbon), biogenic silica (from diatoms), as well as rate estimates of primary production and calcification.

Ocean acidification: My lab has examined the impact of ocean acidification on phytoplankton. Specifically, we are following changes in phytoplankton community structure, biomass, calcification, and the standing stock of particulate inorganic carbon as a function of increased partial pressure of CO2.

Coccolithophore mixotrophy: We have recently begun a new study of coccolithophore mixotrophy in a combined laboratory and field project.

I balance my life of science as a jazz trombonist with the “Novel Jazz Septet”. See for more information on my jazz activities.
