Physical and Biological Processes Affecting the Distribution of Hypoxia on the Louisiana Continental Shelf

EPA Grant Number: R827785E02
Title: Physical and Biological Processes Affecting the Distribution of Hypoxia on the Louisiana Continental Shelf
Investigators: Rabalais, Nancy N. , Justic, Dubravko , Turner, R. Eugene , Wiseman, William J.
Institution: Louisiana State University - Baton Rouge
EPA Project Officer: Winner, Darrell
Project Period: March 17, 2002 through March 16, 2003
RFA: EPSCoR (Experimental Program to Stimulate Competitive Research) (1999)
Research Category: EPSCoR (The Experimental Program to Stimulate Competitive Research)



The main objective of this research project is to better define the physical and biological processes affecting the distribution of low oxygen through experiments with instrumentation, empirical relationships, and modeling. Development of technological capabilities and expanded modeling efforts will provide the necessary data sets to improve our research competitiveness, as well as support the development of human resources, particularly in public and graduate education. The project will address research questions about vertical and horizontal transport of oxygen, timing and duration of low oxygen, cross-shelf and alongshore dynamics, transformation of hypoxic water masses, and integration of the physics (winds and currents) with biological processes.
