We have reorganized our Research Programs. Most of the research projects from this program are now organized under the Ecological Prediction Research Program.
GLERL AQUATIC CONTAMINANTS and BIOGEOCHEMISTRY RESEARCH PROGRAMS
There are two primary components within this research program:AQUATIC CONTAMINANTS and BIOGEOCHEMISTRY
AQUATIC CONTAMINANTS RESEARCH
Task Leader: Peter Landrum
The Aquatic Contaminants Research Program combines process studies and mathematical modeling focused on toxic organic contaminants to increase our understanding of the dynamics and effects of pollutants in the ecosystem.
The purpose of this research is to 1) determine
processes that govern contaminant fluxes into and out of
sediments, that mix contaminants within sediments, and that
control the transfer of contaminants from sediments into the food
chain, 2) develop methods for assessing the extent or degree of
sediment contamination and for determining bioavailability and
bioaccumulation of sediment associated contaminants, and 3)
improve methods for interpreting the hazard of bioaccumulated
contaminants by developing the time-dose response relationships
based on accumulated body residue. 
Current Projects
- Contaminant Effects: Investigations on the Utility of Body Residue as the Dose Metric.
- Sampling the Resuspendable Pool of Sediments and Associated Contaminants and Measuring Mass and Contaminant Fluxes in Lake Michigan Using Sediment Traps
- Bioavailability of Sediment-Associated Toxic Organic Contaminants

BIOGEOCHEMISTRY RESEARCH
(Task Leader: John Robbins)
The Biogeochemistry Research Program is designed to help answer questions and address issues about the ecosystem's biogeochemical response to stressors.
Employ radioactive and stable isotopes to establish
geochronologies and probe major Great Lakes and coastal ecosystem
processes and their alteration by anthropogenic stresses such as
contamination and climatic variations, with emphasis on the
carbon and nitrogen cycles, and the use of natural and fall-out
radioisotopes.
Current Project
This project is divided into the following sub-projects:
