Survey season for Alexander lab

Surveying season is now officially here for the Clark Alexander lab.  After the successful completion of Wassaw Sound last year, Mike Robinson, Claudia Venherm and Lee Ann DeLeo will be surveying Ossabaw Sound for bathymetry and benthic habitat this summer.

During June, the lab team (Alexander, Jennifer Colley, Robinson, Venherm) were busy on Sapelo Island working within the context of the Georgia Coastal Ecosystems – Long Term Ecosystem Research (GCE-LTER) program.  They collected cores near sediment-elevation monitoring sites to compare seasonal/annual sediment accumulation rates to 100-y average rates.

“This comparison highlights the relative importance of daily and episodic sediment input to marsh accretion,” Alexander said. “In addition, we probed and augered transects from the upland out into the marsh to gather stratigraphic information for an upland runoff manipulation experiment.”

This experiment will modify the flow of groundwater from the upland to the marsh over a period of years to detect changes in salt marsh community structure, as a proxy for drought and development impacts to natural groundwater flows.


MAREX partners in LTER Workshop on Sapelo Island

MAREX partners annually with UGA Marine Science faulty, UGA Marine Institute and Sapelo Island National Estaurine Research Reserve (SINERR) to provide logistics and instruction for teachers enrolled in the Sapelo Island Long Term Ecological Research Workshop. John Crawford provided natural history instruction and lead nightly sea turtle walks on the beaches of Sapelo.

Green Eggs and Sand a success

The annual Green Eggs and Sand Horseshoe Crab Teacher Workshop was held May 2-4. It was co-hosted by the University of Georgia Marine Extension Service and the Sapelo Island National Estuarine Research Reserve. Twenty nine educators from South Carolina and Georgia came together to learn about and better understand the issues, science, and management of the horseshoe crab/shorebird phenomenon. The highlight of the workshop was viewing spawning horseshoe crabs and migratory shorebirds in the field. The workshop funded in part by Sapelo Island National Research Reserve provided a unique environmental education experience for teachers and a curriculum package that teachers can take back to their classroom.
