Photo showing coral with dark spot diseaseNew USGS publication examines dark spot syndrome in starlet corals

An article published October 7, 2014, by USGS microbiologists Christina Kellogg and Michael Gray, examines one of the most prevalent coral diseases in the Caribbean, dark spot disease (also known as dark spot syndrome). In collaboration with scientists from Lawrence Berkeley National Laboratories, DNA microarrays, a technology that measures a large numbers of genes simultaneously, were used to compare bacterial communities between healthy and dark-spot coral colonies in Dry Tortugas National Park and Virgin Islands National Park. Overall, the findings do not support the hypothesis that dark spot in the massive starlet coral (Siderastrea siderea) is linked to a bacterial pathogen. The dataset does provide the most comprehensive overview to date of the bacterial community associated with this coral species.

USGS scientists Patrick Barnard (Pacific Coastal and Marine Science Center, California) and Nathaniel Plant (St. Petersburg Coastal and Marine Science Center, Florida) will serve as subject matter experts in an Inter-Agency Sea-Level Rise Panel Discussion hosted by the Federal Emergency Management Agency (FEMA) on October 16, 2014. During the past 10 years, multiple hurricanes have caused billions of dollars in damage and much human suffering. Climate change and sea-level rise have received much attention as the Nation strives for improved resiliency. FEMA Risk Mapping, Assessment and Planning (Risk MAP) Federal Coastal Partners are analyzing potential impacts of sea-level rise, and supporting disaster planning for coastal states and communities. Barnard and Plant will bring their expertise in sea-level rise forecasts to a discussion panel including members from FEMA, EPA, NOAA, and USACE. For more information, contact Patrick Barnard,, 831-460-7556.
