Outstanding in their Field: Featured REEF Field Station, Cape Eleuthera Institute


REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.

The Cape Eleuthera Institute (CEI), a marine research facility, is located at the south end of Eleuthera in the Bahamas. Much like REEF, CEI realizes the importance of collaboration and encourages students, visitors, and community members alike to partake in ongoing scientific research with the overarching goal of marine conservation.

CEI works closely and shares facilities with the Island School, a semester abroad program for high-school students. All of the research programs that operate out of CEI teach a project-specific research class each semester to the students. REEF surveys have been successfully incorporated into a number of these projects. Most notably, the Patch Reef Ecology project uses REEF surveys for long-term monitoring of fish communities that are resident to the network of patch reefs in Rock Sound, the vast, watery, “backyard” of CEI. REEF surveys have been used to collect reef fish species and abundance data for this project for nearly a decade now! Students assisting with the data collection learn Caribbean reef fish ID skills and become well versed in the REEF Roving Diver Method. All data collected by students are contributed to the REEF database and available for use by others.

Most of the reefs that are surveyed by students are located in shallow waters adjacent to mangrove creek habitat. These reefs are small, isolated coral heads that provide important transitional habitat for many reef species that begin their life in mangroves and eventually head to deep water to reproduce. Due to their location and abundance, these reefs are easy to access and make great project sites for conducting research. In fact, Lad Akins, REEF’s Director of Special Projects, and Stephanie Green of Simon Frasier University, are conducting a long-term research project monitoring lionfish impacts on reef fish communities using a network of these shallow scattered patch reefs. Skylar Miller, employed by both REEF and CEI and based in Eleuthera, is responsible for monthly data collection for this important project.

REEF members are at the heart of our grassroots marine conservation programs. Over 50,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.

This month we highlight Valerie Lyttle. Valerie joined REEF in 2004 and has conducted 437 surveys. She is a member of REEF's Pacific Advanced Assessment Team. Here's what she had to say about REEF:

When and how did you first volunteer with REEF? How did you first hear about REEF?

I started doing REEF surveys in 2004 after taking Janna Nichols' PacNW Fish & Invertebrate ID courses. I was learning on my own and trying to remember at least one new fish/critter each dive, but the course really helped solidify things. The idea of being able to contribute my observations to the greater good really appealed to me.

What inspires you to complete REEF surveys?

I like knowing that I’m contributing to a large database and that others may benefit as a result. Seeing how dive sites and critters change from times of day, seasons of the year, etc. keep me going. Even surveys from winter dives where few species are noted have value, as it helps illustrate trends. I love being able to “speak fish” & be a critter geek with like-minded people.

Do you dive close to where you live, and if so, what is the best part about diving there?

I dive locally because otherwise I’d only get to dive once a year or two otherwise! I think it’s important to practice stewardship of your local waters and sites on whatever level you are able; every bit counts. My favorite local site is Redondo (Highline MaST Pier) for several reasons; it’s close, it never disappoints, and it’s diveable just about any time. Many of my “firsts” were there; my first Six Gill shark, my first Big Skate, the only Pacific Electric Ray and Mola Mola sightings I’ve ever had, my first Grunt Sculpin, my first Giant Pacific Octopus (or GPO, as we call it here), my first Stubby Squid. This is a site for all abilities and there are interesting things to see at every depth.

Do you have a favorite local (or not) REEF field station or dive shop?

There are two favorite local REEF fields stations, both of them dive charters. Bandito Charters know the Puget Sound waters and its critters solidly, and always provide a great experience. Pacific Adventures, based in Hood Canal, Washington, are also heavily involved in local REEF and other projects that promote the health of Hood Canal waters. Both organizations promote stewardship and love talking critters!

What is the most fascinating fish encounter you’ve experienced? What is your favorite fish or invertebrate?

The first time my buddy and I encountered courtship behaviors of Painted Greenlings at a local dive site. The male was sporting full mating colors and clearly had only one thing on his mind. Even though it was winter and the water was very cold, we stopped and watched the dancing and flirting for a good 10 minutes. My favorite critters hands down are jellies, in particular Lion’s Mane, aka Sea Blubber jellies. Their vibrant reds, oranges and yellows make them look like an underwater fireball that I find simply mesmerizing.

Do you have any surveying, fishwatching, or identification tips for REEF members?

Go slow, don’t be in a hurry. Get to know your local critters and their behaviors. Carry a magnifying glass. Dive at different times of day and different seasons so you can appreciate the entire spectrum.

Honoring Our Golden Hamlet Club Members

No, it's not a club of Shakespearean enthusiasts! Rather it's a club of citizen scientist superstars - those REEF members who have conducted 1,000+ surveys in the REEF Volunteer Fish Survey Project. The very first Golden Hamlet member was Linda Baker, achieving the status in 2005. Today, there are are sixteen members of the Golden Hamlet Club. We recently created a plaque, now hanging at REEF HQ in Key Largo, with the names of our honored volunteer surveyors -- Lad Akins, Linda Baker, Judie Clee, Janet Eyre, Dave Grenda, Doug Harder, Lillian Kenney, Peter Leahy, Rob McCall, Franklin Neal, Mike Phelan, Bruce Purdy, Linda Ridley, Dee Scarr, Linda Schillinger, and Sheryl Shea. Congratulations to you all. Thanks to their dedication, and those of the 14,000 other volunteers who have participated in the Survey Project since its inception in 1993, we have generated the largest marine fish sightings database in the world. Who's going to be the next Golden Hamlet surveyor?

Grouper Moon Scientists Talk Live with School Children From Under the Waves

Grouper Moon researchers, Brice Semmens, Christy Pattengill-Semmens, and Steve Gittings, join educator, Todd Bohannon, for a live-from-the-field chat with Caymanian classrooms. They explained a typical research day and showed much of the research equipment used.

It was a science lesson with a difference, broadcast live from beneath the waves with thousands of endangered fish in attendance. Earlier this month, Grouper Moon Project scientists, Dr. Brice Semmens from Scripps Institution of Oceanography, and Dr. Christy Pattengill-Semmens from REEF, hosted three live-from-the-field web chats with students from 18 classrooms at 13 schools in the Cayman Islands, The Bahamas, and Washington State (US). The first of the three web chats was broadcast from the Grouper Moon base of operations on Little Cayman, and featured scientists explaining the research objectives, day-to-day activities, and research equipment used during the project. The other two featured Brice diving and answering questions from the students, first on the Nassau Grouper spawning aggregation and then on the famous Blood Bay Wall. The webcasts are archived online here.

Now in its third year, the Grouper Education Program presents students with a multi-faceted view of Nassau Grouper, in which students create their own understanding of this important species. Key curricular concepts include: the historical role of Nassau Grouper in the Caribbean, its role as a top predator and its positive impact on local reef health, and the conservation challenges facing the species.

Brice Semmens, who presented the underwater webcasts, said students were excited to witness science in action. “As they explore the aggregation with me, the immediacy and reality of the experience really touches them. We are giving students their first diving experience – and it happens to be with thousands of huge, endangered reef fish.”

The work of the Grouper Moon research project – a collaboration between REEF and the Cayman Island Department of Environment has led to fishing restrictions at the aggregation sites and an increase in numbers of the endangered fish.

In-kind logistics and technical support is provided by Southern Cross Club, Little Cayman Beach Resort and Reef DiversCayman Airways, and LIME.

Putting It To Work: New Publication on Effectiveness of Lionfish Culling

REEF staff co-authored a new publication in the scientific journal PeerJ that features research findings from our Invasive Lionfish Research Program. The paper, titled "Setting the record straight on invasive lionfish control: Culling works", evaluates the effectiveness of lionfish removal efforts. Frequent culling of the invasive Indo-Pacific Lionfish throughout the Caribbean has been shown to cause a shift towards more wary and reclusive behavior by lionfish, which has prompted calls for halting culls. The paper addresses those concerns and reviews research conducted by REEF and other efforts. Culling successfully lowers lionfish numbers and has been shown to stabilize or even reverse declines in native prey fish. Partial culling is often as effective as complete local eradication, yet requires significantly less time and effort. Abandoning culling altogether would therefore be seriously misguided and a hindrance to conservation. The authors also offer suggestions for how to design removal programs that minimize behavioural changes and maximize culling success. The paper is available for online viewing here.
