Recently a report by the Marine Conservation Institute, entitled “Gulf Gems: Treasured Places in Troubled Waters,” highlighted ten of the most spectacular of these ecological gems. The featured ecosystems include: Pulley Ridge, the deepest known photosynthetic coral reef off the continental U.S. found 200 feet below the ocean surface which is vibrantly colored and inhabited by more than 60 species of fish; Madison Swanson, Steamboat Lumps and The Edges off the Gulf coast of Florida, consisting of limestone cliffs and rocky outcrops that support arrow and hermit crabs, basket stars, sea fans and Oculina coral;Viosca Knolls, a conglomeration of deep sea coral communities due south of Mobile and 1,640 feet beneath the ocean’s surface that support a range of diversity generally only seen in shallow water coral reef ecosystems; and South Texas Banks (Southern Bank, Hospital Bank and Mysterious Bank to name a few of the 40 banks discovered so far), “drowned” coral reefs that thrived when sea levels where much lower, but continue to house a wide array of marine life.Sadly, each of these gems is at risk. However, as discussed in “Gulf Gems,” there are ways to protect them if we act soon. Read the full report here. Cyn Sarthou is GRN’s Executive Director.
