As their mission statement says:
Reef Environmental Education Foundation is a grass-roots organization that seeks to conserve marine ecosystems by educating, enlisting and enabling divers and other marine enthusiasts to become active ocean stewards and citizen scientists.
REEF’s longest-running and most well-known work, the Volunteer Fish Survey Project teaches volunteer SCUBA divers and snorkelers to collect and report information on marine fish populations as well as selected invertebrate species. The data are collected using a standardized method and are recorded in a publicly-accessible database on REEF's website, available to both divers and scientific researchers. If you're heading to a new area, you can check out their database by geographic area and find out the most commonly seen fish there.
They've also been active in fighting the lionfish invasion in the Caribbean and lately have been able to catch invasive species before they can get established.
Every year, REEF runs dive trips all around the world for novice and expert fish surveyors alike. An excellent group of people and membership is free.

WDHoF was founded as a professional honor society for women who have made significant contributions to diving in a wide variety of areas. We were privileged to join them for the 15th anniversary trip to Utila. They continue to add new members but they also support an extensive program of scholarships, training grants and mentoring activities to bring more women, and men, into the field. Associate membership is $30 and you can be sure your money will go to support their programs. Another excellent organization we're proud to be associated with.
