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).

Explore our Fishinar webpage, register for the sessions you like, and we'll see you online!
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 Naomi Wooten. Naomi has been a REEF member since 1999, and has conducted 143 surveys (all in her home state of California). She is a member of the Pacific Coast Advanced Assessment Team as an Expert Surveyor. Here's what Naomi had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
My friend and I participated in a Great American Fish Count dive in Monterey in June 2005 led by John Wolfe and did my first REEF surveys. A local reporter wrote about the event and said that my buddy and I were excited to find an elusive fish and mistakenly named a very commonly sighted fish. I have had a REEF number since 1999. I think I signed up at a scuba show exhibit.
Have you participated in any REEF special projects or Field Surveys?
I was part of the Monterey Bay National Marine Sanctuary Advanced Assessment Team Project in 2012. After the last dive, my tank went bouncing off the boat into the ocean on a rocky ride back to the dock, and I unwillingly contributed to the artificial reef of Monterey. The best part of the story is that several team members and REEF generously pitched in and helped me replace the tank. I put a REEF sticker on that tank!
What inspires you to complete REEF surveys?
I am motivated to complete surveys by an unexplainable interest in stats and a slightly competitive spirit. Doing surveys contributes to a growing database that others have used in scientific papers and debates. When I started, Kawika Chetron was the top surveyor in California with about 300 surveys. Three hundred surveys became my lifetime goal. I am almost halfway there.
What is your favorite part about being a REEF member?
I love doing REEF surveys because they are so easy and surveys can be part of any dive. I am happy that I can contribute without being a scientist, fish expert, or copious surveyor.
What is your favorite fish or marine invertebrate?
Instead of being a rare fish, my favorite is the blue rockfish, which is very common in Monterey. I smile every time I see the first one on a dive. There is nothing like the peaceful awe I feel when I slowly move into a school of these beautiful fish and am temporarily allowed to be part of their group.
Do you have any surveying, fishwatching, or identification tips for REEF members?
Well, this is my tip for myself. Don’t compare yourself to other REEF members you know and don’t feel bad that you cannot identify (or find) tons of fish and invertebrates like they can. Concentrate on ones you can identify for sure. Keep adding to your personal list and honing your critter-finding skills.
If you haven’t yet booked a REEF trip, or if you are considering another, please take a look below. There are still a few spaces left, especially in the first half of the year when colder temperatures at home may make a tropical dive vacation look especially inviting. In particular, be sure to check out our trips to Fiji aboard the luxurious NAI'A liveaboard. We have 3 spaces available (1 double cabin and one share female space), May 2-12, and 1 male share space left on our second trip, May 12-19. We have also just added a trip to St. Lucia in December. To find out more information or to secure your space on the Fiji trip or any of our other 2015 trips, contact us at trips@REEF.org or call 305-588-5869.

To those who are in the know, St Vincent is considered the critter capital of the Caribbean. To those who watch fish, it is known that the rare is commonplace and that the fishwatching is unlike any other location in the Caribbean. REEF’s data from the June Field Survey supports those claims. With a team of 13 divers, the REEF group recorded an astounding 243 species, more than 65 of which were unlisted “write-ins” on the survey forms.
Diving with Bills Tewes at Dive St Vincent, long time REEF supporter and widely regarded “Caribbean Character”, the team split up on two boats and survey sites around the southwest end of the island. Long-time REEF expert Franklin Neal provided an extra special view from above and into shallow water as he snorkeled, while other team members spent hours on each dive exploring varied habitats and depths.
Special finds during the week would take an entire newsletter to list, but there were a few fish that stood out including the still undescribed Bluebar Jawfish on most sites, five frog fish on one dive, multiple black brotula, various pipefish commonly sighted and the largest spotfin gobies (10 inches?!) we’ve ever seen. The fish of the week may well have been the Golden Hamlet that Bill pointed out as his favorite fish and the species that adorns the cover of Reef Fish Identification.
The diving was bottom time unlimited and many dives exceeded two hours finishing in shallow water. Habitats were varied and visibility ranged from good to excellent on all of our dives. REEF is already planning our next Field Survey to dive St Vincent in August of 2008. The project will be led by Paul Humann and will be a must for any serious fishwatcher.

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.
