We have a full line-up of dive show appearances planned this year. If you are in the area of one of these shows, please stop by the REEF booth to find out what new and exciting things are happening. In 2013, we will be at: Our World Underwater (Chicago, February 15-17), Beneath the Sea (NJ/NY, March 22-23), Northwest Dive & Travel Expo (WA, April 20-21), and Northern California Dive & Travel Expo (Bay Area CA, May 11-12). We are always looking for volunteers to help at the booth. If you are interested in being a REEF ambassador, contact Martha at martha@REEF.org.
We are pleased to share the publication of two new scientific papers that utilize data collected by REEF volunteers in the Monterey Peninsula area of California. Co-authored by REEF Pacific Advanced Assessment Team (AAT) member, John Wolfe, and REEF Director of Science, Dr. Christy Pattengill-Semmens, the companion papers were published earlier this summer in the journal CalCOFI Reports. The first paper, Estimating Fish Populations From REEF Citizen Science Volunteer Diver Order-of-Magnitude Surveys, describes several mathematical models to convert order-of-magnitude count data (the type of data collected during REEF Roving Diver Technique surveys) to a numeric mean. The second paper, Fish Population Fluctuation Estimates Based on Fifteen Years of REEF Volunteer Diver Data For the Monterey Peninsula, California, used the best-performing model technique to evaluate population trends in rocky reef fish species along the Monterey Peninsula. Over 3,000 REEF surveys have been conducted in this region over the last 15 years. Many of these data were collected during an annual project within the Monterey Bay National Marine Sanctuary conducted with the help of members of the Pacific AAT. Changes in relative density over time were reported for 18 fish species, including several fisheries-targeted species. Strong concordance was also found between REEF data and those collected by Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO), a consortium of academic institutions. Results showed that data collected by REEF have great potential to augment and strengthen professional research data and serve as a valuable baseline to evaluate marine reserves. Both of these papers can be found on the REEF Publications page here - www.REEF.org/db/publications (as well as downloadable from the CalCOFI Reports webpage).

This past Columbus Day, I attended a special event in Norfolk, Virginia, where the ex-USAFS Vandenberg is in its final preparatory stages for deployment next spring, 6 miles off the coast of Key West. REEF will monitor the Vandenberg over the next 5 years in a similar monitoring and assessment project to the just completed 5-year Spiegel Grove assessment in Key Largo. The sinking of the Vandenberg is expected to add millions of dollars in diving/tourist related revenue to Monroe County. The hope is that the Vandenberg will not only add tourist revenue but also will reduce the diving pressure on the natural reefs in the area, “loving our reefs to death.”
REEF’s role will be assessing the biological impact the Vandenberg has on the fish community in the vicinity of this new addition. We fully anticipate that the Vandenberg will add to the fish species richness of the area as fish pass through and eventually settle onto the site as residents; provide protected areas for protected IUCN listed species such as Goliath and Nassau groupers; and increase the fish biomass in the area as the fishes on the Vandenberg mature and then reproduce, in effect seeding the surrounding reefs. The Vandenberg will be deployed in approximately 140-ft of water, close to 540’ in length (just 30-ft longer than the Spiegel), but weighs almost 3 times as much as the Spiegel Grove at around 15,000 tons! REEFMAKERS™ is currently reducing the height of the ship and taking some of the towers and satellite dishes and strategically placing these structures onto the deck, adding a lot of complex structure that should be very attractive habitats for fishes. The aim is to sink the Vandenberg in less than 3 minutes, adding a dramatic crescendo onto a multi-year project in the making!
We are currently working out the final monitoring plan but we anticipate a pre-deployment event in the spring of 2008, followed by 3 additional monitoring events next year using our Advanced Assessment Team members. Similar to the Spiegel, REEF will monitor not only the Vandenberg itself but 7 surrounding reference sites over several days per event. REEF’s data analysis from our 5-year Spiegel project, once complete, will assist us in the Vandenberg project expectations. The sinking of the Vandenberg has been in the planning stages for several years and REEF will be working directly or indirectly with several partners on this project including:
REEFMAKERS™ in New Jersey and Artificial Reefs of the Keys (ARK) based in Key West will be responsible for sinking the Vandenberg, along with the direct support of the Florida Fish and Wildlife Conservation Commission. REEF is excited to be a part of this project with all its intrinsic biological, socioeconomic and educational value.
Here are a few notes and news bits we'd like you to know about:
On Saturday, February 9, REEF hosted the first annual For the Love of the Sea benefit dinner and auction at Amy Slate's Amoray Dive Resort in Key Largo, Florida. The event was a huge success! More than 150 guests attended a sold-out event, enjoying a picturesque sunset set to island music and the awe-inspriring underwater photography of authors and REEF founders, Paul Humann and Ned DeLoach. REEF raised more than $25,000 thanks to successful silent and live auctions and the generosity of event sponsors in the Keys and greater REEF community. Proceeds of the event will support ongoing citizen science projects to engage volunteers in marine conservation.
Many thanks to event sponsors for their support and to the local REEF "Fun Raisers" event planning committee. Please click here for more information on the event.
The recent invasion of Indo-Pacific lionfish into Atlantic waters has been causing great concern among researchers, marine park and fisheries managers, and divers. REEF, in partnership with Bahamian dive operators Stuart Cove and Bruce Purdy, NOAA, the United States Geological Service (USGS), the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem. As part of REEF’s Lionfish Research Program, over the last two years REEF has coordinated 12 research projects that have involved over 175 REEF volunteers. This research has generated a wealth of in-situ observations and over 1,000 lionfish specimens, which have led to great advances in the understanding of the biology and potential impacts of this most unwanted invader.
REEF’s most recent field project at Stuart Cove’s Dive Bahamas in May 2008, involving over 20 volunteers and researchers, found that the problem continues to get worse. The team gathered data on nearly 200 specimens of lionfish to determine relative abundance, size increases, reproductive status, growth rates, predator prey relationships and movement. Findings included:
Lionfish continue to grow in size: Tagging data show growth rates exceeding 190mm/year, far larger than necessary to reach sexual maturity.
Site Fidelity: All 12 previously-tagged specimens that have been recaptured indicate strong site fidelity even after 6 months.
Prey: Lionfish continue to amaze us during stomach content studies. The recent effort turned up new records including two entire spotted goatfish, a large brown chromis, a small reef octopus, and even a small mollusk in its shell. Lionfishare eating nearly anything that will fit into their mouths.
Reproduction: Lionfish reproduction occurs throughout the year – many gravid females and a small recently settled juveniles have been found.
REEF’s future fieldwork will concentrate on lionfish movement, trap design, habitat preference, and local control measures. Our next project is scheduled to take place at Stuart Cove’s Dive Bahamas in Nassau from September 14-20. If you would like to help with our ongoing work please consider joining us as a field volunteer and/or making a contribution to REEF’s Exotic Species Program.

The USS Hoyt Vandenberg is the most recent ship to be placed as an artificial reef in the waters off Key West, Florida. The ship was sunk on May 27, 2009, but three weeks prior to the sinking the REEF team was in action conducting surveys of the sinking site and 7 other adjacent sites for comparison. The data will be used by the State of Florida to document fish recruitment onto the wreck and response of nearby reef sites to the new structure. In addition to regular REEF fish surveys, the team is also gathering important fish biomass data at two sites and recording any observations of non-native titan acorn barnacles, orange cup corals or non-native fish including lionfish.
The pre-deployment surveys at the sinking site did not document any fish present at the sandy bottom site though one barracuda was seen swimming through the area shortly after. Combined data from the 7 reference sites documented 159 species including rare sightings of pugjaw wormfish and cherubfish (rare for the Keys). The summary of data can be found here.
REEF will continue regular monitoring of the Vandenberg and reference sites through next summer, with a final report due by the end of 2010. A huge thank you to all of the REEF experts joining in on the effort including Rob McCall, Tracy Harris, Dave Grenda, Brenda Hitt, Jamie Giganti, Lisa Canty and Pat Zuloaga.
