The study of phytoplankton dynamics in Chesapeake Bay by remote sensing of ocean color from aircraft

Principal Investigator:

Lawrence W. Harding, Jr.

Start/End Year:

1997 - 2001

Institution:

Horn Point Laboratory, University of Maryland Center for Environmental Science

Description:

The objective of this research is to use ocean color data from aircraft remote sensing to determine the distribution of chlorophyll in Chesapeake Bay. We will use a combination of the data from aircraft overflights with two instruments, the Ocean Data Acquisition System (ODAS) and the SeaWIFS Aircraft Simulator (SAS III), with those from shipboard and satellite studies to assess the relationship of principal forcing functions in the Bay to seasonal and interannual variations in phytoplankton abundance. A series of 25-30 flights is proposed for 1997, spanning Iate February through October. This project represents a continuation of the regional remote sensing program we have developed in recent years, entails the use of a modified aircraft instrument with additional capabilities and the addition of a modeling component based on our work in quantifying long-term trends of chlorophyll in the Bay.
