Skidaway Institute Fall Lecture Series begins Monday, September 20

The Skidaway Institute of Oceanography 2010 Fall Lecture Series, “Crystal Ball: Changes Afoot for Our Oceans and Coast in the 21st Century,” will kick-off on Monday, September 20, at 7 p.m. at the Jewish Educational Alliance (JEA) on Abercorn Street. The same program will be repeated on Thursday, September 23, also at 7 p.m., in the McGowen Library Auditorium on the Skidaway Institute campus.

The first program in the four-week series will feature speakers Skidaway Institute director Jim Sanders and Gray’s Reef National Marine Sanctuary superintendent George Sedberry.

In his talk, entitled “Our Impact on the Ocean,” Sanders will address how human beings alter and influence the oceans.

“These effects include greenhouse gas emissions, nutrient enrichment, habitat modification, overfishing, and more,” said Sanders.

The talk will provide an overview of these processes and summarize evidence that the scope and scale of human activities now have the oceans on a new trajectory towards an uncertain future.

In the second lecture of the evening, Sedberry will discuss reef fisheries and their management off the southeastern United States coast. Sedberry will describe some problems and possible solutions in the regional reef fish fishery.

“Reef fishes are particularly vulnerable to overfishing because they grow slowly, mature late in life at a size where they are marketable but have not yet spawned, are site specific and therefore easy to find, and have complicated reproductive behavior that includes aggregations and sex change,” said Sedberry. “Traditional management tools like quotas and limits have not worked, and more draconian measures, such as large closed areas, have been proposed to restore the populations and maintain sustainable fisheries.”

The lecture series will continue for three additional weeks, with programs at the JEA on Mondays, September 27, and October 4 and 11. The programs on the Skidaway campus will continue on Thursdays, September 30, and October 7 and 14.

All programs will begin at 7 p.m.

Admission to the lectures will be $5 per program for adults. Students and members of the Skidaway Marine Science Foundation and The Learning Center will be admitted free.
