5th Bi-Annual Basics of the Basin Symposium
The U.S. Geological Survey has supported research in Lake Pontchartrain Basin for the last five years.
As part of that study, we have co-sponsored and co-hosted a bi-annual research symposium that is organized
by the Pontchartrain Research Committee, formed in 1992 shortly after the first Basics of the Basins Research
Symposium was held. The mission of the committee is to promote good science for the Pontchartrain Basin.
Other sponsors include the Lake Pontchartrain Basin Foundation, the Freeport-MacMoran Project Pontchartrain
Ecosystem Research and Education Program, the Coalition to Restore Coastal Louisiana, and NOAA Coastal
Services Center, South Carolina.
Jim Flocks answers a question
about Lake Pontchartrain surficial sediments and geochemistry at the poster session/ice breaker during the
2000 Bi-Annual Basics of the Basin Symposium.
The 5th Bi-Annual Basics of the Basin Research Symposium was held May 18th-20th at the University of New
Orleans (UNO). An invited session focusing on the results from the CMGP's Geologic Framework and Coastal
Processes Study of Lake Pontchartrain Basin opened the symposium. Jack Kindinger and Shea Penland
were moderators for the opening session. There were nine oral presentations given by USGS personnel
and collaborators including Jack, Jim Flocks, and Marci Marot (SPFC), Frank Manheim (Reston), Rich Signell
(WHFC), and Shea, Jeff Waters, and Gordon Yamazaki (UNO).
Jack presented a synopsis of the Pontchartrain
cooperative studies that took place between 1994 and 1999 and described the geologic framework of the study
area. Jim gave results from downcore trace-metal studies that indicate that metals concentrations have increased
over background levels during the last 60 years. Frank summarized how geochemical databases developed
during the study can help understand sediment geochemical and environmental relations within Lake
Pontchartrain. Marci discussed surficial sediment dynamics and use of the Be7 depositional indicator in
recent sediment-accumulation patterns. Rich provided a very good overview of circulation, waves, and
sediment resuspension in Lake Pontchartrain.
Video demos: As part of the display, video clips
were used to demonstrate the deployment and recovery of vibracores. Also, computer-simulated visual
models were used to show how winds and currents move sediments around in Lakes Pontchartrain and
Borgne. Here, Rich Signell is illustrating current circulation within the lakes.
There were several talks by collaborators including Shea,
Jeff, and Gordon. Following these talks, Jack presented a short synthesis of the overall project and opened
discussion to the audience for remarks and possible future direction for basin research. The session was
well attended with good audience participation. Besides oral presentations, a project-overview exhibit was
presented during the poster session.
