REEF Fish Survey Project data were recently featured in a paper in the scientific journal PLoS ONE, Large-Scale Absence of Sharks on Reefs in the Greater-Caribbean: A Footprint of Human Pressures. The study's authors evaluated the status of 14 species of sharks in the Caribbean. In recent decades, large pelagic and coastal shark populations have declined dramatically with increased fishing. However, the status of sharks in other systems such as coral reefs remains largely unassessed despite a long history of exploitation. The paper's authors used REEF data to explore the contemporary distribution and sighting frequency of sharks on reefs in the greater-Caribbean, and assessed the possible role of human pressures on observed patterns.
The analysis was based on 76,340 underwater surveys carried out by REEF volunteers between 1993 and 2008. REEF data are well suited for rarely seen species like sharks because of the wide geographic coverage by REEF volunteers.The authors compared sighting frequency to the number of people in each area surveyed, and used population viability analyses to assess the effects of exploitation on population trends. Sharks, with the exception of nurse sharks, occurred mainly in areas with very low human population or strong fishing regulations and marine conservation. Population viability analysis suggests that exploitation alone could explain the large-scale absence; however, this pattern is likely to be exacerbated by additional anthropogenic stressors, such as pollution and habitat degradation, that also correlate with human population. Preventing further loss of sharks requires urgent management measures to curb fishing mortality and to mitigate other anthropogenic stressors to protect sites where sharks still exist. The fact that sharks still occur in some densely populated areas where strong fishing regulations are in place indicates the possibility of success and encourages the implementation of conservation measures.

Almost 10 years to the day of launching the Fish Survey Project in Hawaii, the 10,000th REEF survey was conducted at Palauea Beach on Maui this past weekend! The landmark survey was conducted by long-time REEF member, Flo Bahr, who was diving the site with a group of active Hawaii REEFers. Flo was recently featured in our Member Spotlight (read her profile here). A huge thanks to Flo and all of the surveyors who have been busy in Hawaii. REEF launched our citizen science program in Hawaii on February 3, 2001, during a week-long celebration with partners from Project S.E.A.-Link, the Hawaiian Islands Humpback Whale National Marine Sanctuary, the Hawaii Department of Land and Natural Resources, and the Maui Community College Marine Option Program. Since then, many other partners have joined forces with REEF as Field Stations. We are looking forward to the next ten years! In honor of our anniversary, we have highlighted a local Field Station and one of our many local surveyors in this month's Making It Count. To celebrate our 10 years in Hawaii, we have scheduled a Field Survey Trip to Maui in April, we hope you will join us! Click here for more information.

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:
- NOAA scientists from the Protected Resources Division are using data on three species of endangered rockfish to evaluate their status in the Salish Sea.
-University of Washington scientists are using REEF data on invasive tunicates to map distribution of the species throughout the Pacific Northwest.
We are pleased to introduce our latest Marine Conservation Interns - Lucy Davis and Brandon Lenderink. Lucy was born and raised in Texas and has spent the past few years traveling around the world. In 2009, she lived in New Zealand assisting with various research projects using her underwater skills as a diver and driving boats. She recently went backpacking through Southeast Asia where she was able to dive and see the Lionfish in its native habitat. Although she began her college degree in elementary education, Lucy now is focusing more on environmental education. Brandon is a Colorado native and a recent biology graduate whose passion for wildlife and conservation has led him to pursue a career in marine biology. Brandon has worked as an aquarist for the Denver Downtown Aquarium, promoting conservation and working the animals such as endangered turtles and Sumatran tigers, as well as for Colorado Parks and Wildlife in the Aquatic Nuisance Species program. Brandon’s future goals are to become a research diver and scuba instructor.
The REEF internship program provides college age juniors, seniors, and graduate students the opportunity to experience working at a nonprofit environmental organization. Interns assist REEF staff with education, outreach, lionfish research, and day-to-day office assistance. Many REEF interns move on to successful careers in conservation and the marine environment, including natural resource agencies, academics, and conservation non-profits (including REEF). If you or someone you know is interested in applying to be a future REEF Intern, visit the application page -- http://www.REEF.org/about/internships/application.
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!
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.
