Adding to Your Life List - Horned Blenny!

One of the most rewarding and fun aspects of being a REEF surveyor is finding a new species to add to your "Life List" (a lifetime compilation of all fish species seen). Even the most experienced surveyors, after hundreds of surveys, occasionally add new species to this list. Expert Caribbean surveyor, Patti Chandler, recently emailed us about one such find. Despite having over 900 REEF surveys under her (weight) belt, she and her husband Scott recently came across a little mystery while diving in front of CocoView Resort on Roatan - a brilliant blenny with BIG cirri on its head. After emailing the photo to a few experts, they discovered that they had captured what is likely the first in situ photos of the species, and also documented the first record of the species in the Western Caribbean. Not only does their sighting of a Horned Blenny (Paraclinus grandicomis) represent a "lifer" for their lists, it was also a new record for the TWA REEF database. Great find, Patti and Scott!

If you have a First Sighting story to share, email us at And did you know? - If you are a REEF surveyor, your Life List can be accessed under the 'My REEF' menu when you are logged in to the REEF website.

Putting It To Work: Who's Using REEF Data, February 2016

Every month, scientists, government agencies, and other groups request raw data from REEF’s Fish Survey Project database. Here is a sampling of who has asked for REEF data recently and what they are using it for:

- A PhD student at University of Washington is using REEF data to evaluate the distribution of Giant Pacific Octopus in the Pacific Northwest, and how their abundance is related to urbanization.

- REEF data were provided to researchers from University of Miami for use as part of the project, "NOAA RESTORE: Ecosystem modeling efforts in the Gulf of Mexico: current status and future needs to address management and restoration activities." Data will be used to produce maps depicting stressors in the Gulf.

- Researchers from the Sea Doc Society are using REEF data to evaluate Salish Sea fish and invertebrate assemblages and population trends over the last 15 years.

- A student from Indiana University is using REEF data to evaluate fish populations at the Florida Keys artificial reef, Hoyt S. Vandenberg. REEF Advanced Assessment Team members have been annually monitoring the Vandenberg since it was deployed in 2009.

We are proud to announce that on July 1st 2017, the number of REEF Volunteer Fish Survey Project surveys conducted by volunteers in the Tropical Western Atlantic (TWA) region topped 150,000! The 150k surveys have been conducted by 11,123 volunteers at 8,837 sites in the TWA region (which includes the Caribbean, Bahamas, and Gulf of Mexico). The first surveys in the TWA were conducted 24 years ago in Key Largo. Since then, REEF's citizen science program has grown to ocean waters world-wide and has generated the largest database on marine life population status and trends, recently surpassing 217,000 surveys! Visit our Top 10 Stats page to see the most frequently sighted species, the most species-rich locations, and our most active surveyors. We would like to say a huge thank you to all of our volunteers, supporters, and those who make use of these data! We couldn't have done it without you.

REEF's mission is to protect biodiversity and ocean life by actively engaging and inspiring the public through citizen science, education, and partnerships with the scientific community. The REEF Volunteer Fish Survey Project is a key component of our success. The program allows volunteer SCUBA divers and snorkelers to collect and report information on marine fish populations in marine waters world-wide (and invertebrates and algae in temperate waters). Visit the About REEF page to find out more and to see where our volunteers are conducting surveys.

Advanced Assessment Team (AAT) Wrap-Up for July

Upper Keys AAT - Mike Smith, Brian Hufford, Joe Cavanaugh, Marissa Nuttall, Lillian Kenney, Wayne Manning, and Brenda Hitt
Middle Keys AAT - Brian Hufford, Joe Cavanaugh, Marissa Nuttall, Paige Switzer, Wayne Manning, Brenda Hitt, and Ann Outlaw
Joe Cavanaugh, Brian Hufford, Dave Grenda, Erin Whitaker, Mike Phelan, and Brenda Hitt

REEF completed two Advanced Assessment Team (AAT) projects this past month, the Wellwood Monitoring Project and the Spiegel Grove Monitoring Project.  Many of you may not know about REEF's AAT program, please check this link to learn more about this very important REEF program -  Essentially, as REEF members gain more experience identifying fish and conducting surveys, they can move through our experience level testing and hopefully achieve expert status, after which time these members are invited to participate in special monitoring and assessment projects with REEF staff.  To learn more about our experience level testing, please click here -

Both the Wellwood and Spiegel projects were 5-year AAT assessments.  The M/V Wellwood, a 122-meter Cypriot-registered freighter, ran aground on August 4, 1984, on Molasses Reef off Key Largo, Florida. The ship impacted the reef's upper fore reef and remained aground for 12 days. The grounding destroyed 1,285 square meters of living corals and injured 644 square meters of coral reef framework.  In an effort to restore habitat structure and stability to the grounding site, restoration began in May 2002. REEF was contracted by the National Marine Sanctuary Program to document recruitment of fishes onto the site as well as the subsequent changes, if any, to surrounding reefs sites. Our final assessment was completed on July 29th.

The final Spiegel Grove AAT was completed on August 8th. The Spiegel Grove is a 510' LSD that was intentionally sunk as an artificial reef structure in the waters between Molasses Reef and Elbow Reef in Key Largo, Florida, in May 2002.  Previous to the May 16, 2006 sinking of the Oriskany (aircraft carrier), the Spiegel Grove was the largest ship ever intentionally scuttled to create an artificial reef.  Pursuant to the permit received by the Upper Keys Artificial Reef Foundation (UKARF) to sink the ship in National Marine Sanctuary waters, a plan for pre-deployment and periodic monitoring was implemented.  The UKARF contracted REEF to conduct pre-deployment and periodic monitoring of the Spiegel Grove and adjacent natural and artificial reef sites.  Monitoring documented fish presence/absence and relative abundance at 8 sites during 7 monitoring events in Year 1 and then bi-annually thereafter for four years. Thank you to all the AAT members, who over the past 5 years contributed to either of these survey efforts.

I also want to send out a BIG thank you to everyone who helped out on our AAT projects the past few weeks.  In addition to the Wellwood and Spiegel projects above, we completed our annual middle and upper Keys Florida Keys National Marine Sanctuary assessments - 12 days straight!  Specifically, I would like to thank Horizon, Paradise, and Quiescence Divers dive shops, and the following individuals, a couple of whom did all 12 days of AAT project diving- Dave Grenda, Brenda Hitt, Brian Hufford, Lillian Kenney, Wayne Manning, Ann Outlaw, Mike Phelan, and our two past interns (newest AAT members) - Marissa Nuttall and Paige Switzer.

Our next AAT project will be the Biscayne National Park AAT in early October (team already assembled).  Also, the Hoyt Vandenberg will present an exciting and new AAT project for REEF beginning next year.  Currently the ship is being prepared for sinking in Norfolk, VA.  It's due to be brought down to the Keys in January (08) and deployed in early April, about 6 miles off the coast of Key West  We are currently finalizing our monitoring plan for this vessel and will be monitoring this newest artificial reef over the next 5 years, beginning in early spring with a pre-deployment event.  You will hear more about this project in the coming months.

Hope to see you in the water soon.

REEF 2008 Field Survey T-Shirt Contest

tshirtREEF copy.jpg
Help REEF Create The 2008 Field Survey Shirt
2007 Bonaire Field Survey Team Led by Ned and Anna Deloach
Paul Humann led Utila Field Survey, Oct.2007

REEF is asking any interested REEF members to submit to us a Field Survey T-shirt design for our upcoming 2008 season. Those of you who have participated in the past on a REEF Field Survey know that you receive a t-shirt as part of your participation in the program and every year we have a different design. There are only a couple of guidelines for you. Our new REEF Shirt must incorporate our REEF flag with our slogan, Diving That Counts! (I will send interested parties the jpeg file upon request). You do not need to incorporate the dive flag directly into the design, it may simply be on the front breast pocket of the t-shirt, for instance, with your design on the back and in this case, no need to ask
for our logo, we'll take care of that.

You should keep in mind our mission as stated on the top of our homepage, and our mantra, "diving that counts." Also please keep in mind that REEF actively surveys in 5 regions, not just the tropical western Atlantic. Please send your submissions to, making sure they are in an easily readable format such as a jpeg file (preferred). Please send all entries in by Dec. 31, 2007.

Depending on the number of submissions we receive, we may have our members vote on the winner in January of 2008. Past t-shirts have had fish images, divers surveying, cartoons depicting divers surveying with witticisms, watercolors of fish, etc. Most importantly, our t-shirt design should incorporate the conservation-based focus of our Field Survey Program.

Thanks in advance for your participation and our staff will look forward to your entries. First prize will be a signed and framed 2008 Paul Humann print of two beautiful Eagle Rays.


Field Survey Season 2008 - 5 Spaces are still available for our Turks and Caicos Liveaboard on Aggressor II, April 19-26, 2008.
Please contact Travel for You at 1-888-363-3345 or Joe Cavanaugh at 305-852-0030. The 2008 Field Survey page will be completed shortly - please check back in a week for final content.

Grouper Moon Project Kicks Off Expanded Research Efforts

Thanks to a three-year grant from the Lenfest Ocean Program at the Pew Charitable Trusts, REEF and collaborators at the Cayman Islands Department of the Environment (CIDOE) and Oregon State University (OSU) will greatly expand the conservation science research being conducted as part of the Grouper Moon Project in the Cayman Islands. The funded research, entitled "The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management" will evaluate the potential for spawning site MPAs to recover Nassau grouper stocks.

In 2003 the Cayman Islands government protected all five known current and historic Nassau grouper spawning sites in the Cayman Islands. This move was motivated by the 2001 discovery and rapid depletion of a large spawning aggregation (~7000 fish) on the west end of Little Cayman. This rapid legislative response protected the west-end spawning site before all the fish were taken (~3,000 remain), and the site is now one of the largest fully-protected Nassau grouper spawning aggregations in existence. However, the other four spawning sites had previously been fished to exhaustion and are believed to be inactive, i.e. aggregations no longer occur during spawning season.

Over the next three years, REEF will continue the ongoing aggregation monitoring and acoustic research that has been conducted on the Little Cayman aggregation since 2002 and expand efforts to Cayman Brac and Grand Cayman, where historical spawning aggregations were fished out during the last ten years. Four primary research questions being asked as part of the Lenfest-funded project are: 1) Do aggregations form in regions that have been fished out? 2) If aggregations form, do the fish ultimately spawn? 3) Do these aggregations form at historic sites or somewhere else? And, 4) Does spawning at these remnant aggregations result in new recruitment?

The new research kicked into gear last month with a team of Grouper Moon scientists and REEF volunteers who conducted twelve days of field work in Little Cayman and Cayman Brac. The team visually monitored the Little Cayman aggregation, documenting the largest number of fish since the fishing ban was implemented in 2003. Spectacular mass spawning was documented at dusk seven days after the full moon. Grouper Moon scientists conducted extensive work on Cayman Brac to enable future visual monitoring on the historical aggregation site and initiate an acoustic tagging study that will facilitate a better understanding of the behaviors of Nassau grouper on an island with a limited number of reproductively-aged individuals. Later this Spring and Summer, REEF researchers, volunteers and an OSU graduate student will return to the Cayman Islands to conduct larval recruitment studies and begin acoustic tagging on Grand Cayman.

Capitalizing on the the increased breadth of research questions being asked as part of the Lenfest Ocean Program grant, the CIDOE is supporting a larval dispersal study that also kicked off this year under the guidance of Dr. Scott Heppell from OSU. Three satellite drifters were deployed at the Little Cayman aggregation site on the night of spawning. The paths will be recorded by ARGOS satellites for 45 days and the resulting data will be used to develop a larval dispersal model in collaboration with researchers from University of Miami. Check out the 2008 image gallery to see where the drifters are today.

Visit the Grouper Moon Project webpage to find out more about this critical conservation research program and the 2008 Gallery page to see images and video of the field work.

REEF extends a big thank you to the island business who continue to support this project, including the Little Cayman Beach Resort and the Southern Cross Club, as well as Peter Hillenbrand and Mary Ellen Cutts, Franklin and Cassandra Neal, and the 2008 REEF Volunteer Team -- Judie Clee, Brenda Hitt, Denise Mizell, and Leslie Whaylen.  We also greatly appreciate the continued support of our collaborative team, including the CIDOE and OSU, and the Lenfest Ocean Program at the Pew Charitable Trusts.
