REEF Welcomes New Trips Program and Communications Manager

Next time you sign up for one of REEF’s Field Survey Trips, you’ll be greeted by a new voice. REEF has added a new member to the team; welcoming Jamie Dietrich as the new Trips Program and Communications Manager! As Jamie’s position title implies, her main responsibilities revolve around managing REEF’s Field Survey Trips Program. Each year, REEF leads 10-15 week long international Field Survey Trips to diving destinations across the world. Led by marine life experts, participants learn about the ocean while contributing to marine conservation as citizen scientists. Anyone can join REEF and likeminded divers for an itinerary of diving, seminars and fun! Jamie will also be managing communications and marketing efforts for all of REEF’s programs.

Jamie is a midwesterner at heart, but comes to the Keys from the Big Apple where she spent eight years after university working in Experiential Marketing; listing several Fortune 500 companies among her clients. These days, her clientele seem a bit fishy, as she’s traded in the boardroom and business suit for the beach and a wetsuit. Jamie recently became a certified Divemaster and Coral Reef Research Diver, and she spent the majority of the last year developing her conservation expertise on a volunteer marine mission in Fiji. After leaving her island home and returning to the States, she decided to make “island-time” a permanent staple in her life by relocating to the dive capital of the world. Jamie is excited to get her feet wet and continue to contribute towards meaningful work that aids in the protection of what she’s come to love most, the ocean.

We are excited to announce that Lad Akins, REEF Director of Special Projects, is a 2016 recipient of Diving Equipment & Marketing Association (DEMA)’s Reaching Out Award! First presented in 1989, this award honors leaders in the diving community whose significant contributions to the sport have elevated the industry on all levels. Lad will join distinguished past recipients including Jacques Cousteau, Dr. Sylvia Earle and Dr. Eugenie Clark, as well as REEF Co-Founder Paul Humann, and Board of Trustees Members Peter Hughes and Marty Snyderman.

Lad has worked tirelessly since REEF’s founding in 1990 to educate divers around the world about the marine environment and how to actively engage in conservation efforts through citizen science. Due to Lad’s efforts and dedication over the past 26 years, REEF is one of the largest citizen science organizations in the world with more than 60,000 members and over 200,000 fish surveys submitted to REEF’s online marine sightings database.

Lad spearheaded REEF’s efforts to combat the lionfish invasion over a decade ago. Lad has worked with scientists, government officials, the dive industry and the public to spread awareness and to facilitate the management and effective removal of these prolific invaders. His contributions to this issue have been numerous, widespread, and inventive. He pioneered the concept of lionfish derbies, and has authored or co-authored 30 scientific publications, as well as other publications, including “Invasive Lionfish: A Guide to Control and Management” and “The Lionfish Cookbook: The Caribbean’s New Delicacy”, now in its second edition.

Without Lad, REEF would not be where it is today. We are happy that he is receiving the recognition for his work to conserve our oceans and his impacts on countless divers and citizen scientists.

Congratulations, Lad!

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 Laurie Fulton. Laurie lives in Colorado, and has been a REEF member since 2012. She is an Advanced Surveyor (Level 3) in four of REEF's regions. She participated in the REEF Expedition to the Azores last summer as part of REEF's expansion to the Eastern Atlantic and Mediterranean. To date, Laurie has completed 197 surveys. Here’s what Laurie had to say about REEF:

When and how did you first volunteer with REEF?

My first REEF trip was in 2012 to the Sea of Cortez on the Rocio del Mar. I had done volunteer trips with other non-profit groups, and was looking to combine my love of diving with volunteer work. REEF provides the perfect combination of both passions.

If you have been on a REEF Field Survey, where and what was your trip highlight?

Since 2012 I have been hooked on REEF trips and try to do a few each year. Every trip is filled with remarkable experiences, and I consider every new fish added to my life list as a highlight. That being said, it’s hard to beat the extraordinary experience of having whale sharks swim by in the Philippines!

What is your favorite part about being a REEF member?

I really enjoy expanding my knowledge and appreciation of the undersea world combined with the opportunity to dive with like-minded people and contribute to research data. I compare it to birdwatching. In addition to observing, identifying and counting, we get to add our data to a vast online database that is available to researchers around the world. It is citizen science at its best!

Where is your favorite place to dive?

Living in Colorado I don’t get to do much local diving, so I love having the great variety of REEF trips available to me. One of my favorite destinations has been Fiji for the calm warm waters and huge diversity of fish to count!

What is the most fascinating fish encounter you’ve experienced?

A stand out for me was in Hawaii watching a Peacock Grouper coax a Whitemouth Moray out of its hole for a session of cooperative hunting. The grouper kept rubbing up against the eels head until the moray plunged down into jumbled coral and rocks while 5 groupers raced along above it. Just like using a dog to hunt.

What is your favorite fish or invertebrate?

One of my favorite marine creatures has to be the octopus. I have had many encounters with these intelligent animals over the years and am always thrilled to see them on dives. Just watch Hank on ‘Finding Dory’!

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

Before each REEF trip I spend time watching the Fishinars for the region. I also take the survey paper and mark the page number from the book for each species next to it. That way I look at each fish and become familiar with the layout of the survey paper.

What is your most memorable fish find and why? What fish do you really want to see underwater?

Last year in the Bahamas I found a Golden Hamlet, which is pictured on the cover of the Humann and DeLoach book. It is my only sighting after years of diving in the Caribbean, so it was very exciting. It was not a REEF trip so no one on the boat quite got it. I would love to swim with a Mola Mola, it’s just such an odd fish.

The Faces of REEF: 2016 Volunteer of the Year, Janet Eyre

REEF is proud to announce Janet Eyre as our 2016 Volunteer for the Year. Janet has been a REEF member since 2002, and she is one of REEF’s most active surveyors. She is a Golden Hamlet member and to date has conducted 1,612 surveys (and counting!).

Janet spent her early years with REEF climbing the ranks of surveying in the Tropical Western Atlantic and Hawaii. In recent years, she has been instrumental in REEF’s expansion efforts to the tropical Pacific, including the South Pacific and Central Indo-Pacific regions. She is a Level 5 Expert Surveyor in all four of those regions. She has also conducted surveys in our Tropical Eastern Pacific region, and Janet participated in our REEF Expedition to the Azores Islands last summer to assist with our expansion to the Eastern Atlantic and Mediterranean. She has participated in 18 REEF Trips and several Advanced Assessment Team projects.

Janet’s expertise in tropical Pacific fish taxonomy rivals any academically-trained scientist. She has documented over 2,000 fish species in her REEF surveys, and 1,478 of those species have been in the tropical Pacific regions. She holds the record for the most fish seen on one REEF survey: 260 species in 73 minutes at the dive site “Edy's Black Forest” near Waigeo in Indonesia.

Janet volunteers countless hours helping REEF staff create new survey and training materials, and she assists with the error checking and quality control of topical Pacific surveys. She is looking forward to working with our staff on developing the next region for the Volunteer Fish Survey Project, the Indian Ocean and Red Sea.

Janet loves to find new-to-her species, which, after all the surveys in the different regions of the world, is getting harder and harder. She gets particular satisfaction finding undescribed species. In 2015 her quest for getting a fish named after her finally became a reality when she found an unidentified goby in Fiji. It was later described as Eviota eyreae, Eyre's Dwarfgoby.

Janet spends about 100 days a year diving (or traveling to dive). When she is home, she splits her time between San Francisco and Nantucket. We are so grateful for Janet’s enthusiasm and dedication to REEF and our mission. Janet - thank you and congratulations!

Announcing the 2018 REEF Lionfish Derby Series presented by Whole Foods Market®

Derby staff processing invasive lionfish removed from a Florida reef.

Divers and snorkelers in Florida will once again sharpen their spears and hone their lionfish hunting skills to compete in the annual REEF Lionfish Derby Series presented by Whole Foods Market®. This summer marks 10 years of lionfish derbies, and will feature an exclusive partnership between REEF and Whole Foods Market for six derby events around the state. Whole Foods Market introduced lionfish to all Florida stores in April 2016, which is perfect for those who want a delicious, nutritious, and eco-conscious choice. Invasive lionfish are voracious predators from the Indo-Pacific that threaten Florida’s marine ecosystems by devouring more than 170 species of our native fish and invertebrates. Defended from predators by 18 venomous spines, lionfish rule the reefs and reproduce as often as every four days, year round. Though lionfish may seem unstoppable, divers and snorkelers can significantly reduce local populations and allow native fish populations to recover. Lionfish derbies serve to educate the public, provide samples for researchers, and encourage market development, on top of removing thousands of ecologically devastating lionfish.

Recent Manta Ray Sightings in the Florida Keys

In the first few weeks of July we have started receiving reports of several Manta ray sightings at French Reef, near Key Largo, Florida. Mantas are found in the temperate, tropical, and sub tropical waters world wide. However, sightings in Florida waters are uncommon. Some observers saw the mantas swimming in large vertical loops, leading them to think that these animals were coming into the shallow reefs to feed on coral spawn.

Mantas inhabit near-shore and pelagic waters, and can grow up to ~14ft in width. They are primarily filter feeders, using large cephalic fins located on the head to help 'funnel' plankton into their mouths.

So, if your diving in the Florida Keys keep an eye out for one of these magnificent animals swimming by - and be sure to record it on your survey!

Putting It To Work: New Publication with REEF Data Reveals Link of Caribbean Fish Biodiversity Patterns and Sea Temperature

We are excited to share the newest scientific publication that includes data from the REEF Volunteer Fish Survey Project. The study, published in the Journal of Biogeography, used the power of the people in the form of citizen science to produce a new map of marine fish biodiversity across the Caribbean and tropical western Atlantic.

The work, performed by scientists from the Center for Macroecology, Evolution & Climate in Denmark and the Marine Biological Association, studied REEF’s extensive data base collected by our volunteer surveyors to produce the map and find that fish biodiversity is strongly linked to sea temperatures. However, results also show that while fish biodiversity is higher in warmer waters, the very hottest sites in fact have fewer species than sites with intermediate temperatures, something not shown before in previous studies. These results will be of concern given the rising water temperatures in the region.

This ground-breaking research is based on data collected by thousands of marine citizen scientists working within the REEF program. These volunteers have been recording data on the fish species they see during dives for over 25 years and inputting their records into REEF database. This work has enabled researchers to compare different coral reefs and other coastal sites across this tropical region for the first time. The resulting map shows high diversity areas in the Dutch Antilles and the Florida Keys, whereas relatively few species were found in Bermuda, the Gulf of Mexico and Northern Florida.

In order to examine potential explanations for these patterns, the research team looked at potential environmental factors that might be associated with them, including natural factors, such as temperature, salinity and depth, and human-based factors, such as population density. Analysis proved the number of fish species recorded at a site could be predicted by how warm the water was at that site, and, to a lesser extent, how deep the site was. While a positive relationship between temperature and biodiversity has been demonstrated in previous research of global patterns, the fine-scale detail provided by this huge citizen science dataset facilitated the discovery of important details of this relationship within the wider Caribbean. Senior author Dr Ben Holt said:

"Rather than being a simple relationship, whereby warmer waters equal more fish species, the relationship seen in the REEF data was “hump-shaped”; warmer sites tend to have more species up to an optimal temperature of around 27C and then the hottest sites become less diverse.”

Further analysis suggests that this result may be partly driven by a few species being adapted to the warmest temperatures. The findings of this study will inevitably be of concern given the fast-rising temperatures of Caribbean water, but the research team urge caution extrapolating their results based on future climate predictions. Dr Holt said:

“The efforts of citizen scientists have provided an invaluable opportunity to study spatial patterns of marine biodiversity. Their data suggest that the hottest reefs are not the most biodiverse but it does not necessarily mean that the diversity of any particular site will change as seawater temperatures change. This is an important area for further research given the importance of these habitats within the Caribbean and around the world.”
