Description:

"St. Croix (STX) is one of three major islands comprising the United States Virgin Islands (USVI) territory. The island encompasses a total land area of 84 square miles, with approximately 70 miles of coastal shoreline. Protection of critical reef habitats is the responsibility of the USVI Department of Planning and Natural Resources, U. S. National Park Service and NOAA, however threats remain to coral reef health from a variety of sources including pollution (LBSP), global climate change and overfishing. Impacts to several populations of Acropora palmata coral were found at Buck Island Reef National Monument (BUIS) and Salt River Bay National Historical Park and Ecological Preserve (SARI) in a 2013 survey of reproductive condition using histological analysis for the presence of gametes, prompting further investigation. As the first step of an environmental investigation into the potential causes of reproductive failure in Acropora palmata corals in the waters of St. Croix, a survey of 25 near shore sites (including MPAs) was conducted during June 2015 to evaluate their toxicity potential. Toxicity of these sites was assessed using sediment porewater in the sea urchin (Lytechinus variegatus) embryo development bioassay. A subsequent effort was also initiated to characterize the observed toxicity in the original samples (preliminary phase I Toxicity Identification Evaluation (TIE)). In addition, sediment interstitial water (porewater) was evaluated for salinity, pH, dissolved oxygen, total ammonia nitrogen (TAN), nitrite, inorganic phosphate and total phosphorus (TP) prior to the bioassay"--Introduction.
