In the summer of 1993, a group of pioneering volunteers conducted the first REEF fish surveys. Twenty years later, the Volunteer Survey Project and other REEF initiatives are leading the way as innovative and effective marine conservation programs. You are invited to join us this summer to celebrate 20 years of success. REEF Fest will take place August 8-11 in Key Largo, Florida, and will feature four days of diving, learning, and parties. Complete details, including the schedule, lodging options, diving and kayaking opportunities, and social gatherings can be found online at: www.REEF.org/REEFFest2013
All REEF Fest events are open to the public, but pre-registration is requested for social events and workshops. Register using this online form. Tickets are required for the Saturday Dinner Cruise celebration. Purchase dinner cruise tickets online here. A quick look at the schedule can be seen here. Questions? Please send us an email at REEFHQ@REEF.org or call us at 305-852-0030. We look forward to seeing you all in August!
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 Joe Gaydos, Ph.D., an avid REEF volunteer in Washington State and Director of the SeaDoc Society (a REEF Field Station). Joe has been a REEF member since 2003 and has conducted 120 surveys. He is a member of the PAC Advanced Assessment Team, and Joe was instrumental in initiating the AAT San Juan Islands Annual REEF Monitoring Project that kicked off this summer (see story in this enews issue). Here's what Joe had to say about REEF:
How are you involved as a REEF member?
I conducted my first REEF survey in Washington State in 2003, and have been doing them ever since. In addition, the program I run, the SeaDoc Society, is a REEF Field Station. We’ve hosted numerous fish and invertebrate identification classes and multiple Great Annual Fish Count dives, but I’m most excited about our new monitoring program collaboration. We’ve partnered with REEF to have Advanced Assessment Team Divers come to the San Juan Islands for annual week-long survey trips. We expect that over the next 8-10 years these data will help us understand long-term sub-tidal changes in the ecosystem.
What inspires you to complete REEF surveys? What is the most interesting thing you’ve learned doing a REEF fish survey?
I live and dive in the Salish Sea, a 17,000 square kilometer inland sea shared by Washington and British Columbia. The data collected by REEF volunteers are valuable to the managers in the region who are working to recovery declining species like Northern Abalone and Rockfish. I love being able to collect data that is meaningful.
In your opinion, what is the most important aspect of REEF’s projects and programs?
As a scientist, I love that the REEF data are collected in a way that is scientifically rigorous. Volunteers are trained and their level reflects their training and experience. Also, it is great that the data are collected and stored in a way that they will always be available for evaluation – even decades from now. This is citizen-science at its finest.
Where is your favorite place to dive?
My favorite place to dive is about 2 miles from my house. It’s a high current area split by an island so you get the benefits of seeing all of the invertebrates that flourish in the current, but you can always dive on one side of the island or the other. The site is familiar, but strikingly beautiful and I always find something new. The water is cold here and people generally expect everything to be dull and they are amazed to see videos or stills of colorful invertebrates and fishes.
Is there a fish (or marine invertebrate) you haven’t seen yet diving, but would like to?
Here, most everybody wants to see a Giant Pacific Octopus – 150 lbs, 2,240 suckers (unless it’s a male, then they only have 2,060) – what’s not to love. But me, I still want to see a Pacific Spiny Lumpsucker. They’re only the size of a golf ball, but dang are they cute. When is Disney going to make a movie starring one of them?! Maybe this year.
REEF is excited to announce that we have added a new invertebrate and algae survey program to the Northeast region (Virginia - Newfoundland). Similar to our other temperate regions, REEF surveyors in this area can now record all fishes as well as a select group of 60 invertebrate and algae species. Species included in the program were selected in consultation with regional scientists and experts to serve as a representative sample of the biodiversity of the region. Consideration was given to species that are habitat indicators, are harvested, and those that are just fun to look at (like nudibranchs!). REEF Outreach Coordinator, Janna Nichols, launched the new program at the Boston Sea Rovers meeting last month. As part of the new program, we have created a new underwater survey paper that includes the invertebrates and algae, as well as a waterproof color ID card. New training curricula are currently being developed for Northeast Fishes and Northeast Invertebrates and Algae. All of the new materials can be found on the REEF online store. A big thanks to all who helped shaped this program, provided guidance, and donated images for the new materials.

Here's an excerpt from a recent review from a fellow REEF member:
"Doing surveys is a lot of fun and knowing what I am looking at has helped hold my interest in my SCUBA diving generally. The educational component is exceptional and I would add that the people that work for REEF are simply amazing and dedicated individuals who really demonstrate they want what is best for the members and the critters we encounter. I'm glad to be associated with such a fine organization!" Thanks Keith!
Funded by a grant through the US Fish and Wildlife Service, REEF’s Lionfish Program Coordinator, Elizabeth Underwood, will travel to cities throughout the Southeast United States to conduct a series of lionfish collecting and handling workshops. These workshops are meant to educate and engage stakeholders (recreational divers, professional divers, environmental groups, students, general public, etc.). Workshop topics will include background of the invasion, lionfish biology, ecological impacts, recent research findings, collecting tools and techniques, market development and ways to get involved. Workshops are free of charge and open to the public, however registration is required. To register or learn more visit www.REEF.org/lionfish/workshops. We hope to see you there! Scheduled workshops include: May 6th—New Orleans, LA; May 7th—Ocean Springs, MS; May 8th—Panama City, FL; May 11th—Pensacola, FL; May 12th—Mobile, AL; May 14th—Tallahassee, FL; May 26th—Morehead City, NC; May 28th—Durham, NC; June 4th—Jupiter, FL; June 8th—Charleston, SC; June 10th—Savannah, GA; June 18th—Orlando, FL; June 23rd—Naples, FL.
Itziar Aretxaga, a long-time REEF surveyor who lives in Veracruz Mexico recently sent in this rare fish sighting report about finding a Swordtail Jawfish. What a great sighting! Here's Itziar's story:
"Earlier this year, I was taking part on an underwater photography competition in Veracruz, Mexico. Every year the diving operators and other supporting organizations launch it as a way to draw awareness upon the diversity and richness of the protected National Park of Veracruz. I had no hope of winning anything as I am a novice photographer with a very basic camera and no illumination, but I wanted to support their efforts. Each of us had a 90-minute time limit to take up to 100 photos.
I saw this jawfish on the sandy area immediately below the buoy in Cabomex, Anegada de Adentro, at about 14m depth. I knew it was not any of the jawfishes I had reported before: face markings, behavior, and burrow type gave it away as a different species. I was set on identifying it more than on making any impression on the competition jury, so I spent my allotted 90 minutes by the jawfish, as motionless as possible, and trying to make it get used to the camera just 15cm away from its burrow. The series of photographs allowed me to identify it as a Swordtail Jawfish (Lonchopisthus micrognathus) based on the body bars and the pointy protruding tail, as described in the sketches of the ReefNet Fish Identification DVD. In looking at the REEF database later, I realized it is extremely uncommon to see this species. So all in all, I felt I had won a big prize in that competition!"
Thanks for sharing, Itziar. If you have a rare sighting or fun find to share, please drop us a note.
During the entire month of July we encourage you to try your hand at conducting your first survey if you're new to our Volunteer Fish Survey Project, or to do a few more if it's been a while.
The GAFC began in 1992 when a small group of recreational divers and marine biologists conducted a visual fish count in California's Channel Islands National Park. The effort was modeled after the Audubon’s Christmas Bird Count and has now grown into an international event.
The ideas behind the GAFC are to:
We've revamped the GAFC website, and it's got everything you need to be able to join in the fish counting fun as a participant or to organize your own local event. It can be as simple as hosting a survey dive (throw in a BBQ), or an ID class or presentation about your local fish.
We especially encourage shops, dive clubs, marine science centers and others to organize a GAFC event.
Be sure to visit www.fishcount.org to get the scoop.
See you in the water!
This past summer, REEF completed its 5-year monitoring and assessment of the ex-Navy Landing Ship Dock, U.S.S. Spiegel Grove, intentionally deployed in 130' deep water as an artificial reef off Key Largo in June of 2002. At the time of its sinking, the Spiegel, at 510' in length, was the largest vessel intentionally sunk as an artificial reef. More recently, REEF completed its final report on the data collected, largely through members' efforts in the water these last few years, so a multus gratia (big thank you) from all of us at REEF to those of you who participated on the Advanced Assessment Team monitoring of the Spiegel. This was every bit your project as much as ours. I am asked quite often in the field how REEF surveyor efforts contribute to science, conservation, and education so I want to share with you some of our findings as the Spiegel assessment serves as a great example of the power of concerned and active citizen scientists to effect positive changes in our communities. For a full viewing of our final report, please visit our website at 5 Year Spiegel Grove Monitoring .
Before I highlight a few of our findings, let's go over what our methods were for conducting our Spiegel assessment. Surveys were conducted using the Roving Diver Technique (RDT), a non-point visual survey method that serves as the mainstay for most REEF efforts in the water. The purpose of this method is to gather a comprehensive species list with sighting frequency and relative abundance estimates, for fish species only in the case of this study. Staff and REEF volunteers all had to be members of the Advanced Assessment Team (AAT) for REEF (learn more about how to become an AAT member http://www.reef.org/programs/volunteersurvey/aat). Each monitoring event consisted of 4 days of two-tank monitoring dives at the Spiegel Grove and 7 surrounding reference sites.
The overall objective of the study was to assess any changes in fish community structure over time with the addition of the newly deployed artificial reef, changes not just to the Spiegel site, but changes to the surrounding natural reef sites as well. A central biological question as to the merits of vessel type artificial reef deployments is whether or not they add fish species in terms of both numbers of fish (biomass) and numbers of fish species (biodiversity) to the artificial reef and the surrounding natural reef sites. In other words, in the Field of Dreams metaphor, if you build it will they come and where will they come from? Ultimately, resource managers and other stakeholders hope that the addition of the artificial reef adds fish not only to the targeted site, but seeds surrounding reefs with the reproductive output from the resident fish population. The scale of these questions cannot be adequately addressed in a 5-year pilot study such as the one REEF just completed and that was not our charge but it is important to understand the concept behind sinking ships as artificial reefs. And we should commend Monroe County, the Upper Keys Artificial Reef Foundation (UKARF), and the Florida Keys National Marine Sanctuary (FKNMS) for funding this initial pilot study. A second socioeconomic question not addressed in REEF's work asks the important question of how much SCUBA diving pressure is decreased on natural reefs by the addition of a top recreational dive site such as the Spiegel and how much additional tourist revenue is gained? Finding answers to both the biological and economic questions above are critical in providing guidance for future marine resource management decisions on whether or not to deploy artificial reefs of this type and when and where the sinking of these large retired vessels is appropriate.
Okay, some quick highlights but again for the full report, please visit our website. Over the 5-year study, REEF conducted 76 RDT surveys on the Spiegel itself and another 445 survey dives on the surrounding 7 reference sites. 191 fish species were documented on the Spiegel Grove for all surveys combined. 46 species of fish were observed on the Spiegel just one month after deployment with the average number of species climbing to 76 per monitoring event thereafter. Approximately 3 years after deployment (Aug 2005), persistence in species composition at the Spiegel Grove site through time had increased to levels closer to those of the surrounding reefs. Striped grunts and Tomtates were immediate arrivals on the newly deployed site. Currently, 5 years post deployment, fish species composition on the Spiegel site is more akin to what you would expect on a deeper reef site including schools of Blackfin Snapper, Creole Wrasses, Bluehead Wrasses, Purple Reeffish, Sunshinefish, Bluerunners, Yellowtail Reeffish, Greenblotch Parrotfish, Tomtates, Spotfin Hogfish, Yellowmouth Grouper, Black Grouper, and the Federally protected Golilath Grouper (for a complete list of species sighted and statistical comparisons between study sites take a peak at the report). Blackcap and Fairy Basslets rarely occur in the Keys but interestingly, on several occasions, both have been surveyed on the Spiegel, most notably after hurricane storm surges from offshore. Of course, the Spiegel originally sunk on its starboard side was righted during Hurricane Dennis in July of 2005, confounding results of our survey shortly thereafter. And large, deeply sunk vessels such as this one certainly offer numerous hiding places to groupers in particular, making full visual assessments difficult. We have included in our report suggestions for future studies as well.
REEF would like to thank Mike Ryan of Horizon Divers for supplying important anectodal information about the Spiegel. He was one of the first divers on the newly deployed vessel and has logged more than 240 dives on site since then, meticulously recording fish and invertebrate sightings in the true naturalist vein. Also, REEF thanks Quiesscence Divers and Horizon Divers and Scott Fowler for providing boat and logistical support for all of our diving efforts over the past 5 years. This spring (2008), the Hoyt Vandenberg is scheduled for deployment a few miles off the coast of Key West. REEF will be leading the monitoring efforts over a similar 5-year time period and we'll keep you posted on our efforts. Two suggested readings are referenced in our report, one by Arena et al (2007) and the other by Leeworthy et al (2006) assessing biological and economic impacts of artificial reefs, respectively.
Happy Holidays everyone and if you are visiting Key Largo next year, visit the wreck and see for yourself how things are coming along.
REEF recently completed our Turks and Caicos Field Survey aboard the Aggressor II on Saturday, April 26. We had a tremendous effort by a stellar group of 20 REEF surveyors. Although we have not yet processed the data, I can give a few hints at what we saw during the week-long trip.
Overall, the group surveyed at least 213 fish species over 12 dive sites and 26 survey dives, 5 dives on most days. We surveyed many habitat types including hard and soft coral areas, patch reefs and grass beds but most of our efforts were concentrated along the famed walls along the islands. Some notable fish sightings included: Black snapper (Apsilus dentatus), Golden hamlet (Hypoplectrus gummigutta), Dwarf blenny (Starksia nanodes), Papillose blenny (Acanthemblemaria chaplini), Cardinal soldierfish (Plectrypops retrospinis), Lofty triplefin (Enneanectes altivelis), Almaco jack (Seriola rivoliana), Fringed filefish (Monacanthus ciliatus), Wall goby (Gobiosoma pallens), Black brotula (Stygnobrotula latebricola), Goldline blenny (Malacoctenus aurolineatus), and Punk blenny (Acanthemblemaria sp). We surveyed some large schools of Horse-Eye jacks and saw a number of Caribbean reef sharks. We also had two confirmed Red lionfish (Pterois volitans) sightings (see picture with article). Unfortunately, if there are two Lionfish surveyed, there are undoubtedly many more in the Turks and Caicos islands already.
We had a seasoned group of REEF members, many of whom had been on numbers of past survey trips and 60% of the group participants were expert surveyors. Consequently, our efforts were rewarded with lots of cryptic species sightings such as the ones listed above. The hospitality of the Aggressor crew was superb, gracious, and quite professional. One of the nice things about a live-aboard field survey is the camaraderie that develops between members who share a number of traits such as a love of diving, conservation-minded attitude towards our marine resources, a desire to make positive changes to said resources, and a general fish geekiness for lack of a better term, that rears it's head from time to time in visceral debates about whether someone really saw a Wall goby or not.
Fortunately for us, many members brought their cameras and we were able to verify most unusual sightings with pictures. The learning curve is leveled while on live-aboard with everyone sharing diving/surveying tips and helping each other find and verify common and rare sightings alike.
I would like to congratulate several participants on reaching new experience levels during the week: Barbara Anderson, Marty Levy, Larry Draper, and Kayla Serote all tested into level 5 surveyors. Suzanne Rose, Marie Robbins, and Kay Tiddmann are all new level 3 surveyors. Jerry Dickman is our newest level 2 surveyor. Congratulations to all the participants for a great survey effort for the week and all the good spirit shared. Also, thanks James Brook and Kristi Draper for taking Kay Tidemann under their wings and teaching her during the week, she was our most improved surveyor as a result and her enthusiasm spilled over to the group. I hope to see many of you in the water on surveys later this year. I am currently planning our 2009 Field Survey schedule and will have more details on that in our next Enews edition in May. There are still spaces available on two Field Survey trips for 2008, Paul Humann's Discovery Tour in Key Largo (June 21-28) and the Sea of Cortez with Don Jose (Oct 5-12). If interested in either of these trips, please contact Joe Cavanaugh at 305-852-0030 for the Discovery Tour and Jeanne at Baja Expeditions at 800-843-6967 for the Sea of Cortez trip.
