Oceanwise 2019


The Friends of the GTM Reserve held its annual Oceanwise fundraiser on Saturday, September 28, 2019. This year’s celebration was especially meaningful as GTM celebrated its 20th anniversary as a designated National Estuarine Research Reserve (NERR).

“The money we raised will help fund GTM’s education programs for local youth, research by local and visiting scientists and stewardship of the reserve’s unique and precious landscape,” said Ellen Leroy-Reed, executive director of Friends of the GTM Reserve.

Friends raised more than $47,000 this year through ticket sales, generous donations, a silent auction and interactive games. As the 10th year hosting Oceanwise, this signature fundraiser has become a staple occasion in the Ponte Vedra and St. Augustine communities. More than 200 guests who attended this sold-out event enjoyed food from local restaurants serving sustainable seafood and other locally-sourced dishes, as well as fine wine and beer. Attendees also relished in live music and participated in unique games like migration plinko and flip flop fishing, all while the sun set over the scenic Guana River.

Thanks to our incredible Oceanwise restaurants and caterers: Aunt Kate’s, Bold City Brewery, Cap’s on the Water, The Floridian, Purple Olive, The Reef, Sawgrass Events and Catering, Starbucks Coffee, and The Vintage Baker.

Special thanks to our Oceanwise sponsors: Fletcher Davis, Northrop Grumman, Serenata Beach Club, Gate Foundation, Rayonier, Applied Technology & Management, Amanda Morrow, REALTOR, Howard Services, Davis & Davis CPAs, Mr. John Upp, Herbie Wiles Insurance, Dr. Greg Dent and Mrs. Nancy Osborne, and VyStar Credit Union.
