Understanding and protecting coral reefs around St Croix

Understanding and protecting coral reefs around St Croix

Sep 24, 2025 | Island News

Two scientists with the National Oceanic and Atmospheric Administration (NOAA) recently visited St. Croix to study St. Croix’s coral reefs to guide protection efforts. According to the St Croix Source, the NOAA scientists who visited St. Croix from Miami included Ian Enochs, Ph.D., head of NOAA’s Coral Program at the Atlantic Oceanographic and Meteorological Laboratory (AOML), and oceanographer Nicole Besemer, the Caribbean Climate Operations Coordinator for the National Coral Reef Monitoring Program (NCRMP).

Enochs said, “NOAA recognizes the incredible economic and societal value of coral reefs, including the billions of dollars in tourism and fisheries they support for the U.S. economy, as well as the coastal and storm protection they provide to homes and communities,” he explained. “Our work is targeted at making sure that our American reef infrastructure is maintained for all that benefit from it.”

Enochs also said, ““St. Croix is home to beautiful coral reefs that support important fish populations and buffer the shore from wave energy, as well as provide amazing diving and snorkeling opportunities that bring in tourists and support local businesses,” and “Anyone walking through the towns can see the importance of diving and ocean tourism, and anyone that is lucky enough to actually see the reefs themselves underwater can view their beauty. Reefs are such a vital part of what makes St. Croix what it is.”

Vulnerabilities also exist in St Croix’s coral reefs. In some areas, there has been coral death from bleaching and disease. Besemer shared her observations, “My first time at the monitoring sites was in 2019, and we have now visited in 2022 and 2025,” Besemer said. “I have seen firsthand the difference and amount of coral that we have lost due to bleaching and coral disease in our photomosaics. It’s very important to track these changes and make sure managers, stakeholders and the general public are aware of the status of their reefs so informed decisions can be made to protect and restore them.”

Coral propagation can happen in different conditions. According to the VI Daily News, despite the many factors in play, researchers can identify the windows in time when corals are most likely to release gametes. Over the past week, teams of Nature Conservancy divers scoured the waters off The Deep End and Cane Bay for those gametes while others monitored the corals at TNC’s Coral Innovation Hub in Estate Little Princess. The researchers found a smaller number of colonies than they hoped for. The effects of the bleaching event in fall of 2023 is still being felt. The recent slight yield followed another disappointing spawning season in May, when another brain coral species The Nature Conservancy monitors showed the effects of last fall’s severe bleaching and heating event. When corals bleach, they exhaust their food reserves and find themselves with little energy to procreate according to researchers.

While bleaching does occur naturally, warming oceans means it’s starting earlier, ending later and more intense, giving corals less opportunity to recover according to the researchers in the article. The Nature Conservancy’s St. Croix work — which this week included late nights diving in worm-ridden waters or peering over dimly-lit aquariums — is meant to restore coral reefs by, eventually, churning corals out at scale.
