My husband and I recently joined 10 other REEF volunteers on a Field Survey to Akumal, Mexico. Akumal is located on the Mayan Riviera, quite near the Mayan ruins at Tulum, and about 60+ miles from Cancun, Mexico. Our time was filled with diving and conducting REEF surveys, fish identification seminars, exploring cenotes, and learning about sea turtle nesting research.
We stayed at Gran Bahia Principe Resorts, part of an international resort group, which is really 3 resorts in one and covers an enormous acreage on the ocean. The area was so large that one had to catch one of the resort’s trams to travel from one place to another. Sunny weather is the norm that time of year and we had no rain the entire week.
One of the interesting geographic features in this part of Mexico is the cenote, a type of sinkhole which connects to subterranean bodies of water and sometimes cave systems. The rainwater which fills the cenote is crystal-clear because it has been filtered through rock substrata and contains very little particulate matter. The REEF group had the opportunity to dive and snorkel several of these cenotes when ocean conditions turned too rough for dives on the reef, and it proved to be an amazing and unique experience! Since freshwater and salt water are both found in some cenotes, REEF divers surveyed some unusual fish, and experienced the sensation of diving through a halocline, a region below the surface of a body of water where there is a significant change in density due, in the case of cenotes, to increased salinity. Many of the divers described the experience of ascending from salt water into fresh as akin to a dream state. –“The fresh water was so clear, it was hard to believe I was still underwater!" Strange and unusual formations in the caves accentuated the dreamlike atmosphere. Illuminated only by divers’ lights, stalagmites, stalactites and columns stirred the imagination. Fish, bats and birds find a sanctuary in these caves.
Another unique element of Bahia Principe was a local environmental group, Eco-Bahia, whose members work with the resort to help preserve the stands of coral and other sealife found off the beaches. Eco Bahia’s representative, Diana Garcia Urrutia, explained to REEF members all the goals of their program, including the preservation of sea turtle nests. Many sea turtles, mostly Loggerheads and Hawksbills, return to Bahia Principe’s beaches each summer to dig their nests and deposit their eggs. Members of Eco Bahia along with community volunteers protect the turtles as they nest, then collect the eggs and rebury them in a safe, fenced environment just off the beach. When the baby turtles begin to dig out, Eco Bahia volunteers gather them up and bring in local school children who name each baby and send it safely out to sea with a kiss and a blessing. What an excellent way to assure that younger generations will have an emotional connection to the wildlife of their area!
The Akumal Field Survey was certainly a pleasurable and enlightening experience!

Two of REEF's Charter Members, Douglas and Jane Rorex, recently returned from their annual dive vacation to Bonaire. Of course they conducted REEF surveys, documenting the rich fish diversity that is found on Bonaire's reef. But they also each made milestone dives during the trip. Douglas conducted his 3,000th dive and Jane conducted her 700th dive! Both were given medals from the dive resort and Ned and Anna DeLoach, who were in Bonaire for their annual Marine Life Education Program, signed their log books. Douglas and Jane have been with REEF since the beginning -- they are REEF Members 25 and 26. They participated in one of the very first Field Surveys that was held in May 1994. Douglas is a member of the REEF Advanced Assessment Team and has conducted over 350 surveys; Jane has conducted 85 surveys.
Douglas and Jane greatly enjoy their annual trip to Bonaire -- this was their 15th year! Some of their favorite fish finds include the common but always beautiful juvenile yellowtail damselfish as well as the more cryptic frillfin goby and candy basslet. Douglas also conducts surveys on deep reefs in Bonaire (140 feet+), where he finds sargassum triggerfish and striped grunt. Bonaire is also a great place to find frogfish. One of their favorite frogfish stories is about two frogfish that they found on a large coral head at the dive site Windsock. The female had been there for several weeks and was getting larger by the week (obviously ready to mate). One day as Douglas and Jane were hovering nearby, a smaller male frogfish came from underneath the coralhead, waddled over next to her and sort of nuzzled her. She responded by taking her left pectoral fin and giving him a perfect stiff arm. She really smacked him. The rejected male made a hasty somewhat dazzed retreat back to the underside of the coral head. Douglas looked up at Jane to see her practicing the stiff arm manevaure and considering adding it to her repotorie.
Congratulations Douglas and Jane!! Thank you for your enduring support of and involvement with REEF.
REEF's Pacific Northwest Advanced Assessment Team (AAT) gathered in mid-August to survey fish and invertebrate life in the Olympic Coast National Marine Sanctuary (OCNMS). Twelve divers conducted over 120 REEF surveys in the week-long project on Washington's northwest coastline, gathering data to add to the previous 7 year's worth that the project has generated. Twelve sites were surveyed by the divers. The Sanctuary is home to many colorful fish and invertebrates and is a popular spot for sport diving. It is also a popular spot for fishing and there is concern that biodiversity has been diminishing in the area, especially in some species of long-lived rockfish such as Tiger and China Rockfish. Data collected by the AAT will be helpful in tracking these population trends.
Members of the OCNMS REEF survey team were treated to a great week of diving and lots of exciting sights in this remote and wild part of Washington State. Whales were seen every day. Basket stars and giant pacific octopus were encountered by many. And about half the team conducted an optional night dive to remember off of Tatoosh Island in the open Pacific surrounded by Stellar Sea Lions. Projects like the annual OCNMS monitoring are a great way for active REEF volunteers to apply their skills and expertise. These projects are also just one more reason for REEF surveyors to improve their identification skills and increase their survey experience level.
A big thank you to the participating AAT members: Claude and Janna Nichols, Ron and April Theod, Jeanne Luce, David Jennings, Greg Jensen, Todd Cliff, Nick Brown, Pete Naylor, Lorne Curran and Stan Kurowski. Thanks to Mike Furguson and his great crew at Porthole Dive Charters and to Winter's Summer Inn for supporting the project. Funding for the project was provided by The Sustainable Path Foundation and The Russell Family Foundation.Share on Facebook
Since 2001, REEF has led the Grouper Moon Project, a multi-faceted, collaborative research effort with the Cayman Islands Department of the Environment (CIDOE) aimed at better understanding Nassau grouper reproduction and the role that marine reserves can play in the long-term protection of this endangered species. Earlier this month, we had researchers and volunteers in the field for two weeks to conduct field research on spawning aggregations in Grand Cayman and Little Cayman. The site on Little Cayman represents one of the largest known remaining aggregations of Nassau grouper; our research will provide valuable guidance to both the Cayman Islands government and others throughout the Caribbean on how to best protect this important coral reef fish.
In 2003 the Cayman Island Marine Conservation Board instituted an 8-year fishing ban on Nassau grouper at all known aggregation sites in the Cayman Islands (both current and historic). This followed the discovery by fisherman of 7,000 aggregating Nassau grouper on the west end of Little Cayman in 2001 and the subsequent harvest of 4,000 of those fish over two spawning seasons. At the time, all other known Nassau grouper aggregations in the Cayman Islands had become inactive due to over-harvest. Thanks to a three-year grant awarded in 2008 by the Lenfest Ocean Program of the Pew Charitable Trusts, REEF is conducting research through the Grouper Moon Project to evaluate the current status of the Cayman Islands spawning aggregations and the effect of these harvest protections -- “The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management”.
The broad goals for the 2010 spawning season were to continue monitoring recovery in the large spawning aggregation on Little Cayman, and to expand research into the fate of remnant spawning aggregations on Grand Cayman; aggregations on this island were fished to exhaustion in the recent past. REEF continued education and outreach efforts through public talks about spawning aggregations and the Grouper Moon research. As the sunset provision on the current legislation nears, REEF is working closely with the Cayman Islands government to translate the findings from our research into effective long-term protections. I spent time with the Honorable Mark Scotland, the Minister of Health, Environment, Youth, Sports & Culture, which oversees the Department of Environment in the Cayman Islands, discussing the project, our ground-breaking results, and recommendations for the future of this iconic species.
2010 Aggregation Season Results Summary
The Little Cayman team continued the long-term monitoring of this aggregation, which includes counting the number of fish that show up, estimating the size of the fish, and recording the timing and amount of spawning observed. The REEF research team uses lasers mounted on a video camera to record sizes of fish. If you would like to see what the Little Cayman aggregation looks like during the day, check out this video on YouTube. You will see the laser marks on the fish. Note that these are all Nassau grouper, just in different spawning colors. The team estimated that the number of fish showing up at the aggregation is approaching 4,000. We are also seeing a decrease if average size, which indicates that younger fish are starting to show up (good news!). Spawning was observed on four consecutive nights, starting 4 days after the full moon.
The Grand Cayman team’s primary goal was to document the remnant Nassau grouper aggregation on the East End of Grand Cayman and hopefully observe spawning. The status of this aggregation was initially documented by a Grouper Moon team in 2009. This year, with a lot of help from our partners at CIDOE and Wayne Sullivan and his crew aboard the Glen Ellen, REEF volunteer Denise Mizell was able to head up this critical component of our research. While several hundred fish were found at this historical spawning site, spawning was not documented. Unfortunately, we believe that fisherman were illegally fishing on the aggregation when our team was not on site. It is possible that this disturbance prevented the fish from spawning. This is disappointing news, but we are hopeful that the Cayman Islands government will pass revised legislation and provide more enforcement before next spawning season in order to protect the few remaining Nassau grouper on Grand Cayman.
Why Does This Matter?
Nassau grouper are not just icons of the Caribbean; they are a social and ecological cornerstone of the region’s coral reefs. Historically, Nassau grouper represented one of the region’s most economically important fisheries. Unfortunately, due to intense harvest on spawning aggregations, their populations have dwindled to a fraction of their historic numbers. The species became the first Caribbean reef fish to be listed as endangered by the International Union for the Conservation of Nature (IUCN) and the species is candidate listed under the US Endangered Species Act. The precipitous decline in mass spawning aggregations of Caribbean grouper species has been well documented. The majority of known Caribbean aggregation sites are now inactive due to the ease with which aggregating species are caught. And those that are still active contain significantly fewer fish than the 10s of thousands that historically gathered at these special places.
As part of our work on the Grouper Moon Project, REEF will continue to develop a comprehensive assessment of the status of the Cayman Island’s Nassau grouper spawning population as a guide for future Nassau grouper restoration and conservation policy.
Collaborators and Supporters Who Make This Project Possible
REEF would like to thank our collaborators at the Cayman Islands Department of the Environment, specifically Phil Bush, Bradley Johnson, Croy McCoy, James Gibb, Tim Austin, Gina Ebanks-Pietre, Keith Neale, Delwin McLaughlin and Robert Walton, as well as Drs. Scott and Selina Heppell from Oregon State University. REEF Volunteers have always been at the core of our Grouper Moon field work and 2010 was no exception – heartfelt thanks to Heather George, Steve Gittings, Denise Mizell and Sheryl Shea. The support and assistance of Thor Dunmire is also greatly appreciated. The Grouper Moon Project has continued through the years empowered by the first year’s success and the passion of early project leader Leslie Whaylen Clift. Assistance from OSU graduate student, Stephanie Kraft Archer, is much appreciated. Principal financial support is from the Lenfest Ocean Program of the Pew Charitable Trusts and the CIDOE. Additional funding is from Mr. Wayne Panton, Mr. Dan Scott, Clive and Stella Wood, Franklin and Cassandra Neal, and hundreds of REEF members. Continued in-kind logistical support from island businesses and residents, including the Little Cayman Beach Resort/Reef Divers, the Southern Cross Club, Peter Hillenbrand, Dottie Benjamin, and Judie Clee is also much appreciated. To alleviate the constraints of diving deep depths on regular scuba, several other sponsors came on board to assist in the project, including Divetech and PM Gas of Grand Cayman, Silent Diving of Brockville, Ontario and Shearwater Research of Vancouver, British Columbia.
And finally, our work on Grand Cayman would not have been possible without the generous support of Wayne Sullivan, who donated his vessel the Glen Ellen, his time (and patience), his equipment and technical diving expertise, and his crew, Brady Booton and several others.

REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.
This month we feature Marker Buoy Dive Club in Washington, which has been a Field Station for about a year. The Marker Buoy Dive Club was founded in 1961 and some of its club members have been diving in Puget Sound since the 1960s and 1970s, so they are very aware of long-term changes in some local fish populations. The Marker Buoy Dive Club currently has about 145 members. They have a dedicated group of members who encourage club participation in the REEF program and in other local activities that raise public awareness of the marine life in Puget Sound. The club is very fortunate to have an active REEF Level 5 surveyor (Rhoda Green) who is willing to teach REEF Introduction to Fish and Invertebrate Identification classes.
In addition to offering ID classes, the club hosts survey dives on a regular basis (sometimes as often as once/week) and encourage club members to report their sightings from their own dives. They have added a REEF News section to our monthly newsletter and are featuring a “Critter of the Month” from the PNW Critter Watchers archive. The club will be recognizing the volunteer efforts of members who have been most active in the REEF program and all club members who turn in at least 10 surveys this year will be entered in a drawing for some fun prizes. Some future plans include encouraging members to become advanced level REEF surveyors and to broaden the range of ID classes including Hawaiian fish identification class for club members who are planning to go on a dive trip to Maui. Club members recently remarked "REEF wouldn’t be the program that it is without the efforts and dedication of our regional Outreach Coordinator, Janna Nichols, and all of the people who volunteer their time to teach the classes, host survey dives, log their surveys and report their sightings – keep up the good work!"
Thanks Marker Buoy Dive Club – you’re a shining beacon to us all!
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:
-Researchers used data on yelloweye rockfish frequency of occurrence in the San Juan Islands in Washington to evaluate population status for the San Juan County Community Development and Planning Department.
- The Tunicate Response Action Committee (TRAC) in Washington State evaluated data on three invasive tunicates that are included REEF's Pacific Northwest program.
- A scientist from Florida Fish and Wildlife requested data on yellowtail snapper populations in the Southeastern US to conduct analyses for a stock assessment.

REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations. This month we feature the Dive Club of Silicon Valley. The dive club started organizing Great Annual Fish Count Events (GAFC) over 10 years ago. Club member and leader of their REEF programs, Kari Larson, says "The club has always been interested in ways to help the environment and help divers understand their role as underwater ambassadors. As a club we promote fun and safe diving. The GAFC was a perfect fit." After learning about the GAFC, she and fellow club member and husband, Mike Davis, thought it was "a good fit for the club and sounded fun. It gave us a chance to contribute to ocean conservation." Ten years later, they are still at it. The club has scheduled 3 upcoming ID classes and a survey dive at Lover Point Park in Pacific Grove, CA (details below). Kari and Mike feel that as a grass roots effort, REEF helps promote involvement at even a beginner diver level and that is important. Kari also noted that, "The access to the database is important, it allows our divers to see how their efforts make a difference. The online resources help members not only in our home area but as they travel to different locations they can identify the fish there also". Club members have started participating in REEF's online Fishinars and the club offers Level 2 & 3 REEF experience testing.

REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight John Wolfe. John joined REEF in 1998 and has conducted 530 surveys. John is a member of the REEF Advanced Assessment Team in both the Pacific Coast and Hawaii. In addition to his active survying, he has delved into teaching about REEF and ID and has mentored several surveyors to become experts. He has also taken a keen interest in getting REEF data used by the scientific and management communities, serving on Marine Life Protection Act committees and has written several papers using REEF data. Here's what John had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
I took my first REEF fish ID class in 1997. It was a Great American Fish Count kick-off event organized by Karen Grimmer of NOAA and taught by Dan Gotshall (author of Pacific Coast Inshore Fishes). My friend Rachid Feretti was the area’s most enthusiastic REEF surveyor at that time. Quite the raconteur, Rachid would pigeonhole anyone (including curious tourists) to describe the REEF diver survey program. In the late 1990’s I only did a handful of surveys every year, thinking of them as special dives with special equipment; I was also a volunteer diver for the sheriff’s department, diving black water and not getting to the ocean as much. In the new millennium I realized that it was more fun to conduct a REEF survey on EVERY ocean dive I did. That was the big break-through. When I realized I could simply put my slate on a retractable harness and tuck it under my BC belly strap, it became a standard piece of my diver gear, taken on every dive.
If you have been on a REEF Field Survey, where and what was your trip highlight?
Since 2003 I’ve participated in every annual REEF Advanced Assessment Team monitoring project in Monterey, my local dive area. It’s always a fabulous assemblage of skilled cold-water divers and enthusiastic fish nerds, with Captain Phil Sammet entertaining us with salty stories and Christy and Brice Semmens calmly and expertly leading the trips. I’ve been on the Sea of Cortez and Big Island of Hawai’i REEF trips once each, and totally enjoyed both experiences, learning a whole new ecosystem of species.
What is your favorite part about being a REEF member?
REEF totally supports my chosen hobby. My father was a fanatic fly fisherman and my mother is a fanatic bird watcher. It’s only natural that I became a fanatic fish watcher. My REEF experience has also taken me beyond just carrying a slate. Between 2005 and 2007, I served as a diver stakeholder and REEF volunteer representative for the California Central Coast Region Marine Life Protection Act initiative. After three years of intense wrangling between conservation and fishing interests, that effort resulted in a network of Marine Protected Areas along the central coast. In the Monterey Peninsula area we fought so hard that the chairman of the Fish and Game Commission, witnessing the debate, called it the Balkans. Nevertheless, I think the contentiousness of that process led to a resulting network of MPAs that all sides now grudgingly admit is a good compromise.
I have also enjoyed teaching others about REEF and ID. Over the past decade I’ve also given several REEF fish ID classes and presentations about the Marine Life Protection Act Initiative to local divers. I’m always looking for that next special diver who will become an enthusiastic and dedicated REEF surveyor. I have found some special people, like Keith Rootsaert and Alex Matsumoto, who now teach REEF fish ID classes and carry on the tradition.
In your opinion, what is the most important aspect of REEF’s projects and programs?
It’s only now, with fifteen years of data in Monterey, and even more in the western Atlantic, that we’re starting to see the value of the REEF surveys as long term data. REEF scientific advisor, Dr. Brice Semmens, points out that such long-term data are quite rare and precious in ecological research. Furthermore, I think we’ve recently made a big breakthrough on how to statistically analyze the data; it’s a gold mine that we’ve only really started to dig into. I’m really excited about a paper I’m co-authoring with REEF Director of Science, Dr. Christy Pattengill-Semmens, about this topic.
Do you dive close to where you live, and if so, what is the best part about diving there? Where is your favorite place to dive?
The Monterey Peninsula is a special place, with rocky reefs, protected coves, and amazing kelp forests. It’s a two-hour drive from my home in Berkeley, well worth the effort. My favorite dive spots along the Monterey Peninsula include North and South Monastery, now protected in the recently expanded Pt. Lobos marine reserve, as well as Point Lobos State Park itself, the longest running no-take marine reserve in the state. Butterfly House and Point Pinos are wild, spectacular shore dives. I also enjoy the mellower Coral Street and Otter Cove dive sites – and I’ve never had a dull dive at the most heavily dived site of our area, the Breakwater. My favorite local boat dive site is Dali’s Wall outside of Stillwater Cove – it’s always a highlight of our annual Monterey field survey.
What is your favorite fish or marine invertebrate?
Do I have to choose? Kelp Greenling, both male and female, are such handsome fish. Juvenile Canary Rockfish are tiny spectacular gold, black and white jewels. Enormous schools of tubesnout threading and weaving their way through a kelp forest is a spectacular sight!
What is your most memorable fish find and why?
Well, I have a few. I’ve only seen one Rockhead Poacher, years ago – it’s a bizarre tiny fish with a punctured pate (pit in the top of its head) that looks just like the orange cup coral it so successfully hides amidst. It's so bizarre, an exciting find! The second would be finding (and eventually photographing) the Masked Prickleback. It is a handsome fish with a tan back, white belly, and broad dark chocolate brown stripe running the length of the fish from eye to tail. This species was only discovered by science in the mid-1960’s, by a night diver at the Monterey Breakwater. That diver, David Powell, later became the Director of Live Exhibits at the Monterey Bay Aquarium. He recounts his discovery of that species in his book “A Fascination for Fish”. Masked Pricklebacks are shy and nocturnal, relatively uncommon and very difficult to photograph. And finally -- an instance of fish ID rookie vindication! On my first Sea of Cortez REEF field survey, I’d made a couple of embarrassing and very public rookie ID goofs early in the week. So later in the week, after coming up from Swanee Reef and telling Brice I’d seen an Acapulco Damselfish, he was certain I’d seen the much more common Cortez Damselfish … until I showed him the photographic evidence. It was the first (and perhaps the only) Acapulco Damselfish the group saw that week.
