Pollutants could pose health risks for five sea turtle species – Science Daily

Researchers at the (National Centers for Coastal Ocean Science’s) Hollings Marine Laboratory and four partner organizations have measured for the first time concentrations of 13 perfluoroalkyl compounds (PFCs) in five different endangered species of sea turtles. While PFC toxicology studies have not yet been conducted on turtles, the levels of the compounds seen in all five […]

Study reveals link between dolphin skin disease and climatic factors

Skin lesions on coastal dolphins are associated with water that’s colder and has lower salinity, say researchers at the National Centers for Coastal Ocean Science. They analyzed photographs collected during routine monitoring studies of dolphins in estuaries and coastal waters of South Carolina, Georgia and Florida and found that in all three sites, the prevalence of skin lesions […]

Florida Red Tide Aging Process May Help Predict When Harmful Algal Blooms will Dissipate

Extensive changes in gene expression were revealed in an NCCOS study of aging in Florida red tides. These changes reflect alterations in metabolism that may provide the tools necessary for developing markers indicative of waning Florida red tide blooms. These results were found using a DNA microarray designed by the NCCOS HAB Genomics Project for […]

Study by NOAA and Partners Shows Some Gulf Dolphins Severely Ill : NOAA Gulf Spill Restoration

Barataria Bay, located in the northern Gulf of Mexico, received heavy and prolonged exposure to oil during the Deepwater Horizon oil spill. Based on comprehensive physicals of 32 live dolphins from Barataria Bay in the summer of 2011, preliminary results show that many of the dolphins in the study are underweight, anemic, have low blood […]

DNA Microarray Tool Successfully Identifies Domoic Acid Toxicity in California Sea Lions

The National Centers for Coastal Ocean Science (NCCOS) has developed a DNA microarray for profiling gene expression patterns in blood to aid in clinical and population level studies of domoic acid exposure on sea lions. There is currently no straightforward way to diagnose domoic acid poisoning due to the highly variable symptoms, the fact that […]
