The Faces of REEF: 2012 Volunteer of the Year, Jonathan Lavan

We proudly announce our Volunteer of the Year for 2012, Jonathan Lavan. Jonathan joined REEF in 2004 and since then, he has logged 324 REEF fish surveys and become a member of REEF's Advanced Assessment Teams for both the Tropical Western Atlantic and Pacific Coast survey regions. He has submitted surveys in five of REEF's six regions. Jonathan's involvement with REEF has been instrumental in spreading the word about REEF and its programs. In 2012, he helped to expand the Volunteer Fish Survey project by instructing for REEF's online webinars, called Fishinars. His background in theatre, sense of humor and teaching style quickly made his Fishinars popular with both new and experienced fishwatchers. He has also assisted by serving as an administrator for REEF's experience level tests. To learn more about Jonathan and his involvment with REEF, check out his Member Profile featured in a previous issue of Making It Count.

As a former diver and staff member of the Monterey Bay Aquarium in California, and a current diver at the John G. Shedd Aquarium in Chicago, Lavan actively seeks opportunities to educate others about marine life, conservation and REEF. He is often a guest speaker at dive clubs and shows, and especially enjoys educating youth. An avid underwater photographer, Jonathan uses his images gathered over the past 10 years to educate others about marine life, and many of his photos appear in art shows as well as online resources. We are so grateful to have a wonderful volunteer who contributes to REEF in so many ways. Thank you, Jonathan!

New REEF Program for South Atlantic States - North Carolina, South Carolina, and Georgia

Two days of workshops were held at the North Carolina Aquarium at Pine Knoll to kick off the new SAS region.

After several years of planning and collaborating with local marine scientists and divers, REEF has expanded the Volunteer Fish Survey Project into another region: the South Atlantic States (SAS). Recreational and scientific divers in North Carolina, South Carolina, and Georgia now have survey materials specific to the local ecosystem, including waterproof color ID cards, waterproof survey paper, teaching curriculum, data entry, and online data summaries. Like all of REEF's regions, all species of fish are reported, but in addition the SAS program also monitors fifty-one species of invertebrates and algae that are important indicator species.

Divers have been able to conduct REEF surveys in coastal waters off these three states since the early 1990s when REEF surveying began, but divers had to use survey materials and data entry tools designed for the entire Tropical Western Atlantic (TWA) region (Florida, Bahamas, Caribbean). Large differences in species between the TWA and SAS meant the survey materials were less than ideal for divers in this region.

To launch the new region, REEF and our partners at NOAA's Office of National Marine Sanctuaries (ONMS) and National Centers for Coastal Ocean Science (NCCOS) led two days of training workshops and survey dives during "Bringing Shipwrecks to Life", a NOAA program for divers to appreciate shipwrecks as historical treasures loaded with divers and plentiful biological treasures. Nearly 70 people attended the workshops and completed 40 survey dives over the weekend in early September. Many workshop attendees passed their REEF Level 2 exam.

REEF Director of Science, Christy Pattengill-Semmens, reported many people learned to really see underwater. “The divers had the usual buzz and excitement that you often hear on a boat full of REEF divers. One diver said, ‘I have dove on that wreck (the Indra) so many times before but I had never noticed that it was covered in coral.’ It's literally covered in Ivory Coral, Occulina spp, one of the invertebrates that we now monitor in the SAS region.

If you live or dive in the SAS region, please contact us to find out more about how you can get involved in the REEF Volunteer Fish Survey Project. And please encourage your local dive clubs, dive shop, or education center to teach the new fish and invertebrate curricula.

Grouper Moon Scientists Talk Live with School Children From Under the Waves

Grouper Moon researchers, Brice Semmens, Christy Pattengill-Semmens, and Steve Gittings, join educator, Todd Bohannon, for a live-from-the-field chat with Caymanian classrooms. They explained a typical research day and showed much of the research equipment used.

It was a science lesson with a difference, broadcast live from beneath the waves with thousands of endangered fish in attendance. Earlier this month, Grouper Moon Project scientists, Dr. Brice Semmens from Scripps Institution of Oceanography, and Dr. Christy Pattengill-Semmens from REEF, hosted three live-from-the-field web chats with students from 18 classrooms at 13 schools in the Cayman Islands, The Bahamas, and Washington State (US). The first of the three web chats was broadcast from the Grouper Moon base of operations on Little Cayman, and featured scientists explaining the research objectives, day-to-day activities, and research equipment used during the project. The other two featured Brice diving and answering questions from the students, first on the Nassau Grouper spawning aggregation and then on the famous Blood Bay Wall. The webcasts are archived online here.

Now in its third year, the Grouper Education Program presents students with a multi-faceted view of Nassau Grouper, in which students create their own understanding of this important species. Key curricular concepts include: the historical role of Nassau Grouper in the Caribbean, its role as a top predator and its positive impact on local reef health, and the conservation challenges facing the species.

Brice Semmens, who presented the underwater webcasts, said students were excited to witness science in action. “As they explore the aggregation with me, the immediacy and reality of the experience really touches them. We are giving students their first diving experience – and it happens to be with thousands of huge, endangered reef fish.”

The work of the Grouper Moon research project – a collaboration between REEF and the Cayman Island Department of Environment has led to fishing restrictions at the aggregation sites and an increase in numbers of the endangered fish. To find out more, visit www.REEF.org/groupermoonproject. The Grouper Education Program is supported by a grant from the Disney Worldwide Conservation Fund. In-kind logistics and technical support is provided by Southern Cross Club, Little Cayman Beach Resort and Reef DiversCayman Airways, and LIME.

Putting It To Work: New Publication on Effectiveness of Lionfish Culling

REEF staff co-authored a new publication in the scientific journal PeerJ that features research findings from our Invasive Lionfish Research Program. The paper, titled "Setting the record straight on invasive lionfish control: Culling works", evaluates the effectiveness of lionfish removal efforts. Frequent culling of the invasive Indo-Pacific Lionfish throughout the Caribbean has been shown to cause a shift towards more wary and reclusive behavior by lionfish, which has prompted calls for halting culls. The paper addresses those concerns and reviews research conducted by REEF and other efforts. Culling successfully lowers lionfish numbers and has been shown to stabilize or even reverse declines in native prey fish. Partial culling is often as effective as complete local eradication, yet requires significantly less time and effort. Abandoning culling altogether would therefore be seriously misguided and a hindrance to conservation. The authors also offer suggestions for how to design removal programs that minimize behavioural changes and maximize culling success. The paper is available for online viewing here. You can find a complete listing of all publications that feature REEF's programs at www.REEF.org/db/publications.

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:

- A scientist from Bermuda Institute of Ocean Sciences (BIOS) requested REEF data to evaluate fish assemblages in Bermuda with regard to no-take reserves, comparing shallow vs. deep water habitats, and to evaluate the impact of invasive lionfish.

- A scientist from Washington State Department of Transportation requested REEF data to help evaluate the impacts of a proposed ferry terminal at Keystone Jetty on three species of protected rockfish.

- A graduate student from University of Miami requested REEF data from New Providence, Bahamas, to compare the measures of rugosity used in various research research methods and their ability to predict fish diversity and abundance.

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 Anne Benolkin. Anne was a REEF Marine Conservation Intern in the spring of 2013. She grew up in Alaska, and after going to college and interning in Florida, she returned to her frosty home state. Following her time as a REEF intern, Anne went on to become a Pro SCUBA Instructor and was awarded the prestigious Zale Perry scholarship, an award named after one of diving’s most celebrated women and the memorable lady-star of “Sea Hunt” (read more about Anne's award here). She is currently working on her Masters degree at Alaska Pacific University, studying the behavior of Day Octopus. Here’s what Anne had to say about her time at REEF and beyond:

What did you enjoy most about your experience as a REEF intern?

When I was a REEF intern my favorite thing was all of the connections I got to make with people all over the world. It was so inspiring to see this community of people brought together by a desire to make the world a better place. I loved leading seminars and teaching enthusiastic people all about reef fish and conservation. I especially loved watching people come together for a cause, like the work REEF does with the lionfish invasion. We took something negative and looked for positive solutions that bring people together.

What inspires you to do REEF surveys?

Diving is such a unique sport. There are a huge variety of people who come from all different backgrounds and they all got into diving for different reasons. Learning about fish and doing REEF surveys adds a whole other element to diving, making every dive uniquely exciting with new things to discover. I feel like I’m making a contribution when I do a REEF survey.

What are you doing these days, post-REEF internship?

My internship at REEF opened a lot of doors for me. I’ve since gone on to become a SCUBA instructor and enroll in a masters degree program. I moved back to Alaska and I was so thrilled when they expanded the REEF sites to include Alaska. I think sometimes people forget about the beauty and diversity that exists in cold water diving.

Putting It To Work: New Publication Out of the Grouper Moon Project

A new publication in the scientific journal Coral Reefs was recently issued based on science conducted as part of REEF's Grouper Moon Project. The paper, titled "Hydroacoustics for the discovery and quantification of Nassau grouper (Epinephelus stratus) spawning aggregations", summarizes results from work conducted during the 2014 Grouper Moon Project field season in the Cayman Islands. Led by Jack Egerton from Bangor University in the UK, the research focused on the use of hydroacoustic technology as a means to monitor the status and ecology of fish spawning aggregations. Egerton was assisted by Grouper Moon scientists, Dr. Brice Semmens and Dr. Scott Heppell, as well as Grouper Moon collaborators from the Cayman Islands Department of Environment. Using a split-beam echo sounder, data were used to visualize and estimate fish abundance and biomass at three Nassau Grouper spawning aggregations in the Cayman Islands. The estimates were compared with diver-collected data. Additionally, the technology was used to examine fish aggregation locations in relation to protected zones.

Patterns in the acoustic abundance matched that observed by the visual estimates reported by our Grouper Moon diver teams - total numbers found at the Little Cayman aggregation were significanly higher than the depeleted aggregations found on Grand Cayman and Cayman Brac. 

Spawning aggregation location examined with reference to seasonal marine protected areas (Designated Grouper Spawning Areas) showed that the aggregations were partially outside these areas at Grand Cayman and very close to the boundary at Cayman Brac. The aggregation on Little Cayman appears to be contained within the protected zone (at least in 2014). However, we know from other Grouper Moon Project data that the fish spend a lot of time traveling in and out of the zone during the day. Additionally, in 2015, the aggregation on Little Cayman shifted a significant distance to the north of the historical location and partially out of the protected zone. The results of this study show the importance of making use of many different approaches for monitoring and aggregations in order to most effectively inform future management of aggregating fish species.

Announcing the Next Generation of REEF.org

reeforg_frontpage.jpg
The all new REEF.org.
mydata_web.jpg
One of the many improved features of the new REEF.org - more flexibility in generating data reports, including exciting ways to view your own survey data.

REEF is excited to announce the launch of a completely redesigned REEF.org website! A unique look, enhanced features, and pages of fresh content ... the address is the same but almost everything else about the REEF website is new. Through enhanced technology and innovative tools, the new Website will enable REEF to more effectively recruit, train and engage divers and snorkelers in the Volunteer Survey Project and REEF’s larger conservation science program. The new REEF.org will also facilitate communication among the REEF community through Member Forums.

The new and very much improved REEF.org is the result of a grant from the Norcross Foundation and a huge amount of work and patience by Ben Weintraub. Ben, a University of Washington Computer Sciences student, created the new site, which includes several new interactive features and a member log-in as well as many of the existing content and features in an updated, easy to navigate and user-friendly site.

Just a few of the features that you will find are:

  • More ways to explore your own survey data, including a REEF Survey Log.
  • Interactive discussion boards, including “ID Central”, a place where you can post identification questions and images of unknown critters for others to comment on, and a “Trip Reports” forum.
  • A searchable map of REEF Field Stations.
  • A central REEF Events calendar, including information on upcoming REEF classes and organized survey dives hosted by Field Stations.
  • Learning resources including quizzes and galleries.
  • An improved REEF Store to order all of your identification resources and survey materials.
  •  

  • And Coming Soon -- Online Data Entry for ALL of our Survey Regions. This long-awaited feature should be available by the end of this week!

     

    To get the most out of the new website, you will need to become a registered REEF.org user, so be sure to create a user login profile.

    The new REEF.org website will enable REEF to more effectively achieve it's mission to educate, enlist and enable divers and other marine enthusiasts to become active stewards and citizen scientists. The site will also facilitate collaboration with REEF’s existing and new partners and allow our programs to reach a broader audience.

    In the coming months, REEF will continue to add new content, and areas still under construction will be completed. All of the REEF staff appreciate your patience in advance as the transition to REEF’s new website is completed.

    This is the third major revision to the REEF website. REEF’s online home was originally launched ten years ago in 1997. REEF would like to extend a huge thank you to Ben Weintraub and the Norcross Foundation for making this new site possible, as well as Dr. Michael Coyne (REEF’s primary IT Support Volunteer and developer of the REEF database), and Brice Semmens and Ken Marks (the designers of the previous two versions of REEF.org).
