REEF Grouper Moon scientists co-authored a recent groundbreaking paper in the journal PLoS One that highlights the importance of regional conservation efforts aimed at spawning aggregations in the Caribbean. This study evaluated genetic connectedness between Nassau Grouper populations throughout the Caribbean using DNA markers. The authors obtained genetic tissue samples from 620 Nassau Grouper from 19 sites across 9 countries, including the Cayman Islands. They found evidence for strong genetic differentiation among Nassau Grouper subpopulations throughout the Caribbean. These results suggest that, despite a lack of physical barriers, Nassau Grouper form multiple distinct sub-populations in the Caribbean Sea. Oceanography (regional currents, eddies) likely plays an important role in retaining larvae close to spawning sites at both local and regional spatial scales. These findings highlight the importance of conservation initiatives such at REEF's Grouper Moon program in the Cayman Islands. A PDF of the paper is available online here. You can see a complete list of all scientific papers that have included data from REEF programs at www.REEF.org/db/publications.

A team of Pacific REEF Advanced Assessment Team (AAT) divers recently conducted a week-long project conducting surveys of fish and invertebrate communities along the rugged outer coast of Washington. The Olympic Coast National Marine Sanctuary covers over 3,300 square miles of ocean off Washington State's rugged and rocky Olympic Peninsula coastline. Sanctuary waters host abundant marine life. A small but important stretch of coastline along the Strait of Juan de Fuca features some of the best diving in Washington State, but is rarely visited because of the remote location and limited diving facilities.
The team included 6 REEF AAT members and conducted 5 days of diving with Porthole Charters. The weather, which is always a wild card out there, fully cooperated and the team was able to visit all of our priority sites within the Sanctuary, most of which have been surveyed annually since 2002. A total of 72 surveys were conducted. To find out more about REEF's work in the OCNMS, visit http://www.reef.org/programs/sanctuaries/OCNMS .
Funding and support for this year's project was generously provided by Washington Scuba Alliance (WSA), an anonymous private foundation, the Winter's Summer Inn in Seiku, and the REEF survey participants. REEF encourages our Washington members to join WSA - it's free.

On August 13th, Lad Akins, lead on REEF's lionfish efforts, was an invited presenter to the Caribbean Fisheries Management Council and other meeting attendees at its bi-monthly meeting in St Croix, USVI. The council is charged with advising the National Marine Fisheries Service on regulations and issues related to commercially valuable marine life species in Puerto Rico and the USVI of St. Thomas, St. John and St Croix.
Based on recent information coming from REEF's work in the Bahamas, the Council expressed great concern over the impending spread to the US Caribbean and beyond and what might be done to best address the invasion. Lad presented the current state of knowledge on the invasion and research results from REEF's collaborative efforts with NOAA, the USGS, the National Aquarium in Washington, Simon Fraser and Oregon State Universities, and REEF volunteers. Following the presentation, and numerous questions from members of the audience, the council made plans to further address the invasion with continued dialogue with REEF and initiation of a technical workshop to develop recommendations for the council.
Come April 25, 2009 we won’t just be REEF Headquarters any longer – the new and improved 1908 conch house that is our office will become the James E. Lockwood REEF Headquarters. How did this come about? In late 2007 REEF was contacted by a law firm that was looking for information on small non-profits in order to make a decision about some monies left by James E. Lockwood in his will. Leda Cunningham (former Executive Director) and Jim Dalle Pazze (REEF Board Member) met with the lawyers and so began the slow dance that lasted for over a year.
During the last few months of 2008, there were several meetings, lots of visits to REEF Headquarters and many phone calls. The suspense was building and it looked like REEF was going to be included in the disbursement of the estate. Right before the holidays the paperwork was sent through and the check arrived on January 2 -- what a great way to start the new year!. Needless to say we were very excited about this generous support. The donation included stipulations to fix up our 1908 Keys Conch House and get her in tip top shape – as such a place of character and charisma deserves. This included the renaming or our beloved REEF Headquarters to the James E. Lockwood REEF Headquarters, to celebrate and honor Mr. Lockwood. James Lockwood was an interesting man and we will have additional background on him in the coming months – he developed and patented a re-breather device several years before Jacques Cousteau made his “first dive”.
On April 25, we are going to have a dedication ceremony – all REEF members are welcome – the program will be from 1:00 – 3:00 PM at the new James E. Lockwood REEF Headquarters here in Key Largo. In preparation for this celebration, we are spiffing up the outside, and completing some very necessary repairs and maintenance.
We look forward to unveiling additional plans for the funds that include revamping and gearing up our outreach program – to spread the REEF word and involve more dive resorts, retailers and citizen scientists in providing valuable data about fish populations. So thank you Mr. Lockwood for helping REEF make the world a better place.

The REEF program has been active in California since 1997 and has accumulated over 6,500 California marine life surveys in the Volunteer Survey Project. There are currently over 137,000 surveys in the REEF database worldwide. The database is online and accessible to anyone.
Earlier this month, REEF auctioned five pre-release, signed and numbered copies of the Tropical Pacific edition of Reef Creature Identification by Paul Humann and Ned DeLoach. The authors donated to REEF the first five pre-release copies of this spectacular book, which is set to be released in mid-November. The long-awaited, 500-page reference detailing 1,600 animals with 2,000 photographs and descriptive text is not only the most comprehensive visual field guide to marine invertebrate life inhabiting the waters from Thailand to Tahiti, but also a pictorial tour de force skillfully bridging science and the aesthetic. Copies #1 - #5 were auctioned off through Missionfish in eBay. In total, $1,735 was raised in the auction. These funds will go directly to support REEF's critical marine conservation programs. We extend a heartfelt thank you to the five generous REEF members with the winning bids. Congratulations, and enjoy the book.
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:
- An educator and researcher from the University of Connecticut is using data as part of a field science class. His students will use the data to evaluate fish populations in advance of their field coursework.
- A postdoc from the Smithsonian Marine Station at Fort Pierce is using data from Stetson Bank in the Gulf of Mexico (part of the Flower Garden Banks National Marine Sanctuary) to evaluate changes in the bank's fish populations.
