Description:

Objective:

This research project seeks to integrate information obtained from physical, geochemical, and remote-sensing measurements to better understand the fate of particle-reactive contaminants in a shallow coastal environment: Lake Pontchartrain, LA. The contaminants examined (e.g., Cu, Cr, Mo, Zn, Pb, U, polycyclic aromatic hydrocarbons [PAHs]) represent a spectrum of pollutants that enter the coastal zone primarily as particulates (i.e., contaminated sediments). We will examine the fate of these contaminants on daily, monthly, seasonal, and decadal timescales.

Progress Summary:

Results to date include the successful collection of monthly cores for the past year. These include cores and water-column samples collected as well as samples from the automatic sampler interfaced with the platform monitoring instruments. Analyses of the first 14 months of samples collected are complete.

Future Activities:

For the subsequent reporting period, we plan to perform sample analyses for the remaining samples, which are expected to be completed in June 2003. The two preliminary manuscripts on which we currently are working will be completed shortly after the sample analyses are complete. Submission of both manuscripts is anticipated in July or August 2003.
