While every one of REEF’s 10,000+ volunteers who have conducted a survey as part of the Volunteer Survey Project are Making Dives That Count, there is a small cadre of surveyors who have taken their passion for fish and critter watching to the next level. They are the volunteers, those most active in each of REEF’s project regions, who have actively strived to move through the REEF Experience Level system, often becoming REEF Experts and members of the Advanced Assessment Team (AAT). And among this group, there are a handful of surveyors who have reached a significant benchmark – the 1,000 survey mark! Passing this benchmark gets you a place in the REEF Golden Hamlet Club. And this Summer, REEF welcomes two new GHC members - Bruce Purdy and Dave Grenda. They join Peter Leahy, Linda Baker, Lad Akins, Judie Clee, Linda Ridley, and Linda Schillinger.

Bruce Purdy is the owner/operator of the Bahamas diving liveaboards Aquacat, Cat Ppalu and Blackbeard's Cruises. He's been a REEF member since 1994 and a member of REEF's Tropical Western Atlantic AAT since 2002. Bruce is a staunch conservationist and has been integral in supporting REEF's lionfish work in the Bahamas. In addition to his work with REEF assessments and lionfish projects, he has also pioneered sea urchin restoration efforts in the Bahamas. Even though he has reached the milestone of 1,000 surveys, Bruce continues to encourage his diver to join him in surveying Bahamian reefs and supporting REEF's conservation projects - Way to go Bruce!!!

Dave Grenda has been a REEF member since 1998, and is one of the very few of our volunteers who have conducted REEF surveys in all four regions -- Tropical Western Atlantic, Tropical Eastern Pacific, West Cost of the US, and Hawaii! He joined the Tropical Western Atlantic AAT in 2001 and has participated in multiple AAT special projects. Dave is also a NOAA Science Diver and has participated in multiple NOAA research cruises in National Marine Sanctuaries. Most recently, Dave started helping with the REEF Grouper Moon Project and just returned from a few weeks on Grand Cayman helping to tag Nassau grouper. His passion for fishwatching shines through on projects and he is always eager to share the joy of a new find. In his "other" life, Dave is a retired Air Force Colonel. Way to go Dave!!!

Hoyt S Vandenberg -- Plans for Sinking in Early May, REEF To Monitor Fish Recruitment

After many years of planning, financial woes and last minute negotiations, it appears that the Hoyt S Vandenberg, a 520-foot troop transport/missile tracking military vessel, will be sunk as the newest artificial reef in the Florida Keys. Recent communication with the State of Florida’s Fish and Wildlife Commission has given the go ahead for REEF to initiate pre-deployment monitoring of the sinking site and 7 other adjacent reef areas to study the recruitment and movement of fish around the wreck and reef sites. 

The one year study will also include surveys of non-native orange cup coral, titan acorn barnacle and Indo-Pacific lionfish. While exact dates have not been set for the sinking, plans are for the ship, located now in Virginia to be towed to Key West in early April and then scuttled 6 miles offshore in May. REEF Advanced Assessment Teams will survey the sites prior to deployment, then again one month following the sinking and quarterly through the remainder of year one. It is anticipated that the wreck will provide significant habitat for fish as well as additional recreational opportunities for fishing and diving activities. Data gathered during REEF’s efforts will aid in determining how effective the ship is in meeting its biological objectives.

Blue Croaker -- What a Find

One of the best parts about fishwatching is that no matter how many surveys you have under your belt, there's always a chance to see something unexpected. Recently I was diving on Davey Crocker Reef near Tavernier in the Florida Keys with four REEF surveyors. As often happens, we got separated, me with my photography and the others surveying. I spotted a brown fish about 8 inches long “drifting” in the water just under a ledge overhang. It sort of looked like a croaker to me, but not one that I recognized. I photographed it from a distance and continued to photograph while moving closer. The fish remained still, just looking at me. Finally, when I got about 6 feet away it retreated into the gloom under the ledge.

Back on the boat we were talking fish -- as usual. One of the others commented about a strange brown fish she had seen under a ledge. It turns out everyone had seen it and no one knew what it was. The entire group were members of REEF's Advanced Assessment Team (AAT, Expert Surveyors), so no one knowing is surprising. After downloading my photos, I researched the mystery fish. My hunch was correct; it was a Croaker, a rarely seen Blue Croaker, Bairdiella batabana. These were the first sightings of this species to go into the REEF database!

So how do you know if it's a Blue Croaker? The body coloration can be copperish to bluish brown. The only distinctive marking is a white crease on the gill cover.

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

    This month we feature Eco-Dives in Key West, Florida, which has been a Field Station since 2010. Eco-Dives owner, Rob McCall, is fascinated by learning and finding new species and enjoys sharing his knowledge and enthusiasm with others. Rob has been a REEF surveyor since 2001 so it was a natural to incorporate REEF into his business. Eco-Dives primarily teaches advanced open-water scuba certifications because it enables them to focus on fun courses such as underwater photography and the REEF Fish ID specialty. Eco-dives was also one of the first dive operators to offer a Lionfish Diver specialty that teaches divers the basics of the lionfish invasion, why it is so detrimental to our reefs, and how to report sightings.

    “Out of 775 REEF survey dives and countless other dives with students, the most unusual fish we have found on our dives has been a pugjaw wormfish.” says Rob. Fortunately Rob was able to snap a couple pictures of it to confirm the identification of such a unique fish. Rob's sighting was only the sixth time that species had ever been reported on a REEF survey.

    Although Key West is not known for its pristine reefs, Rob says the dive sites are convenient, the reefs are well-populated with small-to-medium size fish, and they have mature wrecks with plenty of big fish. The newest addition to the armada of artificial reefs in the Keys, the Vandenberg, is a great dive and a fish magnet. REEF has been monitoring the Vandenberg since it was sunk and Rob has been a great help on a number of the Advanced Assessment Team (AAT) surveys documenting reef fish recruitment over time.

    Rob says that he "really enjoys working with REEF surveyors; they are always so enthusiastic. Doing surveys has made me look much harder at fish, looking for distinguishing features so I can identify them. This results in you seeing so much more during a dive."

    Another GREAT Annual Fish Count

    The 21st annual Great Annual Fish Count (GAFC) took place in July, with many dive shops, dive clubs, and other groups organizing fish ID classes, dive /snorkel days, BBQs and more fun gatherings. The concept behind the GAFC is not only to accumulate large numbers of surveys during the month of July, but to introduce divers/snorkelers to fishwatching and get them started doing REEF surveys. Groups from California, Oregon, Washington, British Columbia, Hawaii, Massachusetts, Maine, Hawaii, Florida, North Carolina, and new to the event in 2012 - New Brunswick, all participated! Once again, this year's largest one day event was held in the Northeast, coordinated by the New England Dive Club. Thank you to ALL participants, and we hope you'll continue conducting REEF surveys on your dives year round!

    Putting It To Work: New Publication Showing Validity of REEF Survey Data

    A new scientific paper published earlier this month in the journal Methods in Ecology and Evolution reports that REEF surveys conducted by citizen scientists compare well with traditional scientific methods when it comes to monitoring species biodiversity. The findings of the research, conducted by Dr. Ben Holt from University of East Angila in the UK, give weight to the growing phenomenon of citizen science programs such as REEF's Volunteer Survey Project. The field study compared methods used by REEF volunteer divers with those used by professional scientists to measure the variety of fish species in three Caribbean sites in the Turks and Caicos. The divers surveyed the sites using two methods – the 'belt transect', used in peer reviewed fish diversity studies, and the 'roving diver technique', used by REEF volunteers. Two teams of 12 divers made 144 separate underwater surveys across the sites over four weeks. While the traditional scientific survey revealed sightings of 106 different types of fish, the volunteer technique detected greater marine diversity with a total of 137 in the same waters. Dr Holt led the research in partnership with the Centre for Marine Resource Studies in the Caribbean and the University of Copenhagen, Denmark. He said: "The results of this study are important for the future of citizen science and the use of data collected by these programs. Very few, if any, scientific groups can collect data on the scale that volunteer groups can, so our proof that both methods return consistent results is very encouraging for citizen science in general. We're living in a world that's changing very significantly. Environmental changes are having a big impact on ecosystems around us so we need to harness new ways of measuring the effect. Our study demonstrates the quality of data collected using a volunteer method can match, and in some respects exceed, protocols used by professional scientists."

    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 Nick Brown. A US Pacific Northwest native, Nick is currently living in St. Kitts. Nick has been a REEF member since 2004 and has since conducted 138 surveys. He is a member of the PAC Advanced Assessment Team. Here's what Nick had to say about REEF:

    How did you first volunteer with REEF?

    I first became involved with REEF in 2004 while working as a research intern for the SeaDoc Society, a marine ecosystem health program based in Washington State. The SeaDoc Society and REEF frequently collaborate to offer free fish and invertebrate identification courses to the public. Although I was still completing my open water certification at the time, the enthusiasm of SeaDoc’s chief scientist Joe Gaydos and REEF’s Janna Nichols was contagious. Within a month of finishing my certification, I completed my first REEF survey and haven’t stopped since.

    What inspires you to complete REEF surveys?

    I take great satisfaction in knowing that every survey I submit contributes to an ever growing database that can be used by the public, researchers and policy makers around the world. Not only am I adding more purpose to my dives by contributing to something useful, I’m able to reference my submitted data later on which functions as my own personal invertebrate (in the PAC region) and fish sighting logbook.

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

    I’ve been very fortunate in being able to dive very close to where I live. Until about a year and a half ago, the vast majority of my dives were in the cold but beautiful waters of my home state of Washington and nearby British Columbia, an area known locally as the Salish Sea. My favorite part about diving in the Pacific Northwest is the large diversity of marine invertebrates. Recently though, I’ve hung up my drysuit and slipped into a wetsuit for the warm Caribbean waters of St. Kitts and Nevis where I’m currently attending veterinary school. My favorite part of Caribbean diving is the great visibility and large variety of ornately colored fish.

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

    For better surveying and fish watching move slowly; not only will your dive last longer, but you’ll notice more and the marine life tends not to be as shy. For identification, I recommend investing in a few fish and invertebrate ID books; often the subtleties between different species are hard to appreciate without a detailed reference.
