Field trip to LUMCON, Cocodrie, Louisiana,

September 16-17, 2001

 

One of our regular field trips is to visit the Louisiana Universities Marine Consortium (LUMCON) facility, located at Cocodrie, near the end of Bayou Petit Caillou. Here we get a chance to observe firsthand the deltaic ecosystem we learn about in class. During the trip we took two boat tours. The first, on Saturday, was to visit the freshwater marsh inland from Cocodrie. The class took three small boats up to the Minor Canal. Along the way they sampled water for temperature, salinity, and dissolved oxygen. They also got to view freshwater vegetation and to learn about the effects of saltwater intrusion along the Houma Navigation Canal.

On Saturday night we participated in a teaching lab at LUMCON. Here we discussed the ecosystems in the delta and how they relate to the Mississippi River. We specifically focused on problems involving nutrient enrichment in the Gulf and the associated hypoxic area west of the mouth of the Mississippi (the Dead Zone). We were able also to discuss some of the water samples obtained during the afternoon trip as well as look at plankton in samples obtained right off of LUMCON.

On Sunday we took the same three boats to Trinity Island, one of the remaining fragments of Isle Deniers, the westernmost major barrier island in coastal Louisiana. Isle Deniers has suffered significant erosion, especially from Hurricane Andrew in 1993. We visited to learn about the barrier island ecosystem and to discuss barrier island restoration projects. During our time on the island we also took part in an ongoing project to clean up the Gulf Coast beach, as well as took time for a little fun. On the way out we took some more water samples and did a little trawling for fish (not very successful). On the way back in we stopped at a fragment of eroding salt marsh to examine the sediments and to discuss issues of marsh erosion in coastal Louisiana.

L) Scott and J.J. fell the power of the sediments; R) On the way out of Cocodrie we saw this modern cemetery placed on an Indian mound. The landscape of the delta reflects how humans have been influenced by the natural processes of the Mississippi River and its tributaries. Here past and present are intertwined and at times indivisible.
