REEF?

REEF is an organization with a mission as followed, " To conserve marine ecosystems for their recreational, commercial, and intrinsic value by educating, enlisting and enabling divers and other marine enthusiasts to become active stewards and citizen scientists. REEF links the diving community with scientists, resource managers and conservationists through marine-life data collection and related activities." Simply put, they want to save the marine wild-life.

What About The Surveys? How Are They Done?

"To collect data for the Project, REEF volunteers use the Roving Diver Technique (RDT), a visual survey method specifically designed forvolunteer data. The only materials needed are an underwater slate and pencil, a scantron form available at no charge from REEF, and a good reference book. "

"The Survey Method:
During RDT surveys, divers swim freely throughout a dive site and record every observed fish species that can be positively identified. The search for fishes begins as soon as the diver enters the water. Thegoal is to find as many species as possible so divers are encouraged to look under ledges and up in the water column. Any sea turtle speciesseen during your dive should also be marked. At the conclusion of each survey, each recorded species is assigned one of four abundance categories based on about how many were seen throughout the dive [single (1); few (2-10), many (11-100), andabundant (>100)]."

Put into a small sentence, you take a waterproff paper and pencil and mark down the fish you see while you dive at the dive site. After which, REEF looks over it and figures out how the ponds are doing marine life wise.

"REEF surveys can be conducted in any of REEF's Project areas:
*Tropical Western Atlantic/Northeast US & Canada (Florida, Caribbean, Bahamas, and Gulf of Mexico), southern Atlantic states (Georgia and South Carolina), and Virginia through Newfoundland
*West Coast of the United States and Canada (California, Oregon, Washington, and British Columbia)
*Tropical Eastern Pacific (Gulf of California to the Galapagos Islands).
*Hawaiian Islands. "

Our class went down to one of the fish ponds located in Kihei next to the Whale Foundation and did a survey. Although, I personally did not get into the water, other kids did. From what I heard the population wasn't all that high and it was a bit hard for them to figure out which fish was which. All in all, I haven't much data to present and for that, I apologize.
