Spring tides and Ice storms

on January 8, 2018

Spring tides are the highest tides of the monthly lunar cycle, and this month’s spring tide was one of the highest of the year (sometimes called a “King Tide”).  By coincidence, this spring tide corresponded with a very rare ice storm on January 3rd; something that hasn’t occurred on this part of the Georgia Coast in over two decades.

The storm prompted the Sapelo Island ferry to shut down for over 24 hours and UGAMI to close for two days.  The spring tide, which was accentuated by high winds, caused minor flooding in particularly low-lying spots such as Shell Hammock Road and Beach Road.  Tree limbs bowed under the weight of the ice, many crashing to the ground. The electricity flickered on and off throughout Wednesday morning, and finally gave out at about noon.  Power remained off for 28 hours, as the temperature plunged to the low 20’s F.  UGAMI’s backup generator kept the lights and heat on in the main lab building, which became a refuge for many of Sapelo Island’s inhabitants.  UGAMI staff and other island residents gathered to warm up and watched a Harry Potter movie in the auditorium on Wednesday night; a few people opted to spend the night in the auditorium and library rather than to return to their cold, dark homes.

In the end, the ice storm and spring tide created minor inconveniences on Sapelo Island.  No significant damage occurred and everything was back to normal by the next afternoon. And it offered a good excuse to take a break, admire the frozen beauty, and watch a movie with friends and neighbors.

Seafaring gators connect marine and freshwater habitats

on November 2, 2017

Research conducted at UGAMI shows that American alligators are an important link between freshwater and coastal marine ecosystems.  James Nifong and Brian Silliman, part of the NSF-funded Georgia Coastal Ecosystem – Long-Term Ecological Research Program, used radio telemetry and GPS trackers to follow the movements of alligators, and discovered that they spend a lot more time in marine environments than previously thought. Their research demonstrates that gators are an important ecological link between freshwater and coastal marine systems.  See a description of Nifong and Silliman’s work on the NSF website.

Hurricane Irma Hits UGAMI

on September 22, 2017

Hurricane Irma hit UGAMI pretty hard.  About ¾ of our buildings had some storm surge flooding, including research & teaching labs; the BIRL dormitory; The Powerhouse (lecture hall/dining hall/kitchen); administrative offices; electrical, auto & carpentry shops; houses; and storage facilities. The main lab and nearby buildings suffered the worst damage, with over a foot of water inside. Electrical power to Sapelo Island was out for a week.

The good news is that none of our vehicles, vessels, or vital instruments were damaged.  The UGAMI campus is a mess but the contractors are already well into the cleanup/restoration process, so we should be back operating at 100% capacity by Thanksgiving.  We’re also trying to use this as an opportunity to improve some facilities and make them less prone to flood damage in the future.  It’s a setback, but it’s temporary, and we’ll come out of it stronger in the end.

UPDATE, 11:00 AM 9/7/17: UGAMI Closing for Hurricane Irma

on September 7, 2017

The Governor has just ordered a mandatory evacuation for Georgia’s barrier islands. To comply with this order UGAMI will be officially moving its closure to 4:30 PM today. We will remain closed through at least Tuesday Sept 12. Check back at this web site for further updates as the situation unfolds.

UGAMI Closing for Hurricane Irma

on September 7, 2017

Due to the approach of Hurricane Irma, UGAMI will close at 12:00 pm on Friday Sept 8 and remain closed through at least Tuesday Sept 12.

A state of emergency has been declared for the coastal counties of Georgia, including McIntosh. The eye of Hurricane Irma is forecast to pass just east of Sapelo Island on Monday afternoon. Regardless of the path that the storm takes, Sapelo Island will likely experience high winds, heavy rain, and storm surge.

UGAMI staff members have been working for the past few days to secure the facilities and preparations are being rushed to completion. The staff will return to Sapelo Island to assess any potential damage as soon as it is safe to do so. Information about UGAMI’s re-opening will be posted on this web site.

12th Annual Sapelo Island Lighthouse 5K Run

on July 5, 2017

Participants, spectators, and organizers of the 12th Annual Sapelo Island Lighthouse 5K Run

 

One of the Independence Day traditions on Sapelo Island is the Sapelo Island Lighthouse 5K Run.  The race course goes from the Nannygoat Beach Parking Lot to the iconic Sapeolo Lighthouse and back to the beach.

 

GCE LTER technicians dominated the field of 30 participants (28 humans and 2 dogs).  Dontrece Smith jumped out front early and built a 100-m lead by the turn onto Lighthouse Road.  His labmate, Alyssa Peterson, started out conservatively, running an even pace throughout the race and steadily working her way up through the field. She passed Dontrece by the halfway mark and kept widening her margin of victory over the second half of the course.

 

Special recognition goes to the members of the University of Florida’s GCE LTER research team, led by graduate student Sinead Crotty.  After finishing the race, they all went back to work on their field experiments in the marsh.  While most of the runners were recuperating on a couch or lounge chair, Sinead’s crew was performing physical labor in mid-day heat, all in the name of science. That’s dedication!

UGAMI Staff Appreciation

on May 12, 2017

On Thursday, May 11, the staff of UGAMI gathered for our annual staff appreciation.  Even that infamous pirate, Captain E.C., was in attendance.  There was much merriment and cake, too.

Sapelo Island’s remote location often means that extra effort is required to get things done.  This group goes the extra mile, every day.

UGAMI installs new seawater system

on March 31, 2017

With funds from an NSF Field Stations and Marine Laboratories grant, we completed renovations of the systems supplying water to UGAMI’s seawater laboratories.  These facilities allow us to maintain a large variety of tanks and aquaria for studying marine organisms in a controlled setting. The new system is far superior to the one it replaced.  It can supply up to 75 gallons of seawater per minute; monitors the creek level and only runs the pumps when the intakes are submerged (preventing damage caused by the pumps running dry); incorporates five 3,000-gallon modular storage tanks to supply seawater at low tide (when the pumps are off); actively manages the pressure in the seawater line to maintain consistent flow; and provides several filter options, including bag filters, a radial flow settler, bead filter, and in-line UV sterilization, so we can supply seawater to suit the needs of any research user. In addition, we have just taken possession of three 1,000-gallon tanks for maintaining and studying larger fish and two 8’ sink trays for washing and processing samples of marsh plants.

Fresh off the boat! Three new 1,000-gallon tanks were just delivered to UGAMI aboard the R/V Spartina. These tanks will be used to study larger fish.

Chris Craft publishes new book on wetland restoration

on March 15, 2017

Prof. Chris Craft with his new book at Sapelo Island, site of much of his work.

Indiana University Professor and UGAMI Faculty Affiliate, Christopher Craft, has just published a new book titled Creating and Restoring Wetlands: From Theory to Practice. Given the challenges and opportunities facing wetlands in the coming century, this book will undoubtedly become an essential tool for restoration practitioners.

Publishing a book of this magnitude is a monumental achievement.  But Chris is quick to credit the UGAMI scientists who came before him for creating this field and building the foundation on which his research is based.

So now, whereas the rest of the world knows him as “that famous scientist who wrote the text book,” we just know him as “Chris, our good-natured colleague who is devoted to mentoring students, loves Sapelo Island, and has a weakness for oysters.”  Congratulations, Chris!
