The end of the year is fast approaching, but there's still time to take a dive trip in 2018! Space is very limited on our remaining 2018 trips - in fact, there are only two spaces remaining on next month's trip to the Eastern Caribbean aboard the Caribbean Explorer II liveaboard. Beginning in St. Kitts on Dec. 1 and ending in St. Maarten on Dec. 8, this trip includes plenty of diving around the islands of the northeastern Caribbean.

REEF members are the heart of our grassroots marine conservation programs. Divers, snorkelers, and ocean enthusiasts worldwide stand behind our mission.

This month we highlight Callie Mack, who has been a REEF member since 2011. She is level 5 expert surveyor on the U.S. west coast in the PAC region, and has submitted nearly 400 surveys. Callie lives in San Diego, where she enjoys diving the nearby kelp beds and rocky reefs to search for interesting invertebrates and fish.
