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.
Earlier this month, on World Oceans Day, we kicked off REEF's Summer Fundraising Campaign with a goal of raising $60,000 by July 31. Thanks to the Curtis and Edith Munson Foundation, who has generously offered to match your donations, we are over one-third of the way to our goal with $10,345 donated and matched so far. To all of our members who have already donated, we extend our sincere gratitude. If you haven't yet had a chance, please contribute today. You can double your donation in the upcoming month by contributing online, https://www.REEF.org/contribute, through our secure web form. Or you can print the donation form and mail or fax your donation, or call our staff at REEF headquarters (305-852-0030).
Your donation will help support REEF services, which are increasingly in high demand. As the lionfish invasion continues to grow, so does our research and response. Legislation to ensure long-term protections of Nassau Grouper spawning aggregations are set to expire in 2011. And after the devastation in the Gulf, REEF’s Volunteer Fish Survey Program data can be invaluable in evaluating the impact of the oil spill to fish populations. Twenty years of support from members like you has made it possible for REEF to build and maintain this valuable history of fish populations throughout our program regions. We could not do this vitally important work without you. We are doubling our efforts now, and we hope you will double your contribution this summer.
World-wide declines in shark and ray populations have prompted the need for a better understanding of their patterns of distribution and abundance. While much of the focus has been on the larger species of sharks, little attention had been paid to the most frequently sighted elasmobranch species in the greater-Caribbean, the yellow stingray (Urobatis jamaicensis). Despite being relatively common and listed as Least Concern on the IUCN Red List, little was known about the status of this species. Unfortunately, it has been quietly declining. Dr. Christine Ward-Paige and her colleagues at Dalhousie University worked with REEF's Director of Science, Dr. Christy Pattengill-Semmens, to examine the status of yellow stingray. The results of this study were recently published in the scientific journal, Environmental Biology of Fishes. Click here to read the paper.
The study used 83,940 surveys collected by REEF surveyors in the western Atlantic. In total, yellow stingrays were observed on 5,658 surveys (6.7% sighting frequency) with the highest occurrence in the regions surrounding Cuba. Overall, sighting frequency declined from 20.5% in 1994 to 4.7% in 2007. However, these trends were not consistent in all regions. The strongest decline occurred in the Florida Keys, the most sampled region, where trends were similar among all areas, habitats and depths. Possible explanations for these changes include habitat degradation, exploitation (this species is collected for medical research and the aquarium trade), and changes in trophic interactions. The results of the study suggest large-scale changes in yellow stingray abundance that have been unnoticed by the scientific community. This study also highlights the value of non-scientific divers for collecting data that can be used to understand population trends of otherwise poorly studied species.

Changing Seas, an original production of Miami’s public television station WPBT2, will host a live online screening event of Alien Invaders, the series’ latest episode focusing on the lionfish invasion in the Caribbean and Western Atlantic. Alien Invaders will be screened live on the Changing Seas website (www.changingseas.tv/webcast) on Thursday, June 2nd at 7:30 p.m. EST. During the screening, dive enthusiasts will have the opportunity to join an online chat with producers and the experts featured in the program. REEF's Lad Akins and researcher Stephanie Green will be be online to answer questions live during the event.
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 feature Patricia Broom (REEF member since 2004). Pat is a member of REEF's Advanced Assessment Team in the Tropical Western Atlantic and has conducted 277 surveys in three of REEF's regions, including some of the first in our newest region, the South Pacific. Here's what Pat had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
About ten years ago while reading a favorite dive magazine I noticed an announcement about an introductory fish identification trip sponsored by REEF and led by Paul Humann. The love of REEF was born!! I responded to the advertisement, encouraged my brother to join me and attended that Field Survey trip. We joined a group of equally dedicated divers eager as we to learn about fish and how to identify them. Paul was a great teacher, very patient and concerned that we not only learn about fish but care about them and the ocean we love.
If you have been on a REEF Field Survey, where and what was a trip highlight?
One of my most memorable surveying moments occurred that week on Paul's trip. On a night dive of a very old wreck with exposed wooden beams I saw my first queen parrotfish in their nighttime cocoons. Each parrot fish occupied a space between two beams framed by basket stars in full bloom. It was a magical sight. I try to take two or three REEF trips a year, they are a great way to learn more and dive with great people. In addition to the regular ID trips, I have really enjoyed the REEF Behavior Trips that are led by Ned and Anna DeLoach. It really completes the learning experience! It is a beautiful sight to watch damselfish guard their algae gardens from predation, observe cooperative hunting, or watch a three foot Midnight Parrotfish at a cleaning station with open mouth and flared gills.
What inspires you to complete REEF surveys?
Prior to that introductory course, I had been diving the Caribbean for twenty plus years. I witnessed the decline in fish numbers and species as well as reef degradation and wondered how many more years I could dive before there was nothing to see! REEF offered me a reason to continue diving, now there was opportunity to give back and enjoy diving again.
Do you have a favorite local (or not) REEF field station or dive shop?
I have found great enjoyment in Cozumel at the REEF Field Station at Aqua Safari, led by Sheryl Shea. She is a gifted teacher determined to make advanced assessment divers of all of us! It just so happens a few of my favorite fish are in Cozumel, the Splendid Toadfish, Sargassum Triggerfish, and Cherubfish, to name a few.

Thanks to a grant from The Russell Family Foundation, we are in the middle of a year-long initiative to actively engage new REEF surveyors in the region and to provide incentive to our existing surveyors to stay active and move up through the ranks of the REEF Experience Level system. We have teamed up with PNW REEF instructor, Janna Nichols, to coordinate a series of free training workshops throughout Washington and Oregon. These seminars will cover the Introductory REEF Fish Identification training, the REEF Pacific Northwest Invertebrate Identification training, and a NEW Advanced Fish Identification training program. Visit the Pacific Northwest Critter Watchers Webpage to see a complete list of classes. The project will also support a series of REEF survey day trips on area dive charters that will be open free of charge to current REEF surveyors who are actively conducting surveys and interested in advancing their REEF experience level. Ten active REEF surveyors recently participated in the first such opportunity - survey dives at two new REEF sites in the San Juan Islands, Washington earlier this month. In addition to conducting REEF surveys. The great news is that everyone on the trip who was eligible to move up one experience level did so! A big congratulations goes to Pete Naylor and Mary Jo Adamas, REEF's newest Pacific Advanced Assessment Team Level 5 members, and the rest of the gang who successfully passed the Level 2 or Level 3 exam.
We greatly appreciate the funding support of The Russell Family Foundation. This project will enable REEF to actively engage divers in marine conservation through support and enhancement of the REEF Volunteer Survey Project in the Pacific Northwest. Traditionally, divers and snorkelers have not received much more than a cursory introduction to underwater ecology or marine life identification. Even after years of experience in the water, most divers are able to identify only a handful of the marine life they see during their dives. REEF introduces marine enthusiasts to the incredible diversity of fishes and other wildlife found in local waters as well as the identification resources and survey methods needed to document these species. Active REEF surveyors advance through five experience levels (Novice: 1-3 and Expert: 4-5), based on the number of surveys completed and passing scores on comprehensive identification exams. While 536 volunteers have conducted surveys in the Pacific Northwest as part of the REEF Fish Survey Project, there are currently only twenty-eight members rated as Expert surveyors. However, expert level volunteers have conducted approximately one-third of all surveys submitted to date. It is clear that as volunteers improve their skills, they are more likely to stay actively involved in data collection.
Happy 2008! REEF is looking forward to a great year for marine life everywhere as 2008 has been designated the International Year of the Reef by the International Coral Reef Institute. In this first editon of REEF in Brief 2008, learn about recently completed biological monitoring at the M/V Wellwood restoration site in Key Largo, Florida, a proposed research only site at Gray's Reef National Marine Sanctuary in Georgia and a host of upcoming REEF Field Surveys to tempt your travel bug.
