Terrence McCloskey (SPCMSC, Mendenhall Post-Graduate Fellow) is attending a small invitational meeting in Bonaire, Dutch west Indies from 10/18 to 10/21. Researchers will be looking at the state of environmental conditions in the Caribbean, particularly in regard to climate change and sea level rise. It is an international conference, with participants primarily from Caribbean countries and Europe. Only 3 of the 24 invitees were from the United States.

USGS researchers at SACNAS conferenceUSGS researchers present research and judge presentations at annual multicultural SACNAS conference

Jennifer Flannery (Chemist, SPCMSC) and Christopher Smith (Geologist, SPCMSC) were invited to speak about their research in a USGS-sponsored session at the annual SACNAS conference, which offers 3 days of elite science, mentoring, training, and cultural activities for all levels of students and scientists. Also attending were Thomas Doyle (Deputy Director, WARC, Lafayette, LA) and Debra Willard (Climate R&D Program Coordinator, Reston, VA). SACNAS is the leading multicultural and multidisciplinary science, technology, engineering, and mathematics (STEM) diversity organization in the USA. Jennifer Flannery and Christopher Smith also served as judges for several undergraduate and graduate student posters and oral presentations.

USGS Oceanographers address the West Florida Barrier Island Governmental Council (BIG C)

On October 26, Oceanographers Joe Long and Hilary Stockdon will address the west Florida Barrier Island Governmental Council (BIG C; to discuss SPCMSC coastal hazards research including recent efforts to measure coastal change following Tropical Storm Colin and Hurricane Hermine. They will also describe the new video camera being installed at Madeira Beach to observe coastal processes and better understand the evolution of Florida beaches. Eleven municipalities residing on the west coast of Florida, from St. Pete Beach to Clearwater will be present at the council meeting.

USGS St Petersburg Coastal and Marine Science Center Scientists to attend 2016 Esri Ocean GIS Forum

Steven Douglas (SPCMSC, Researcher), Xan Fredericks (SPCMSC, Cartographer/Lidar Coordinator), Ginger Range (SPCMSC, Geologist/GIS Specialist), and Heather Schreppel (SPCMSC, IT/Data Management Specialist) will be attending the Esri Ocean GIS Forum from November 1–3, 2016 at ESRI in Redlands, California. The purpose of this forum is to encourage knowledge-sharing across disciplines to help shape the future of GIS design and to discuss ways multi-dimensional data and web apps can help people put scientific information to work.

Journal article 'Bacterial community diversity of the deep-sea octocoral Paramuricea placomus published

Compared to tropical corals, much less is known about deep-sea coral biology and ecology. Although the microbial communities of some deep-sea corals have been described, the study described in the journal article published by PeerJ ( is the first one to characterize the bacterial community associated with the deep-sea octocoral, Paramuricea placomus. The authors are Christina Kellogg, Steve W. Ross, and Sandra D. Brooke.

USGS Center Director interviewed on syndicated radio program about potential impacts of Hurricane Matthew

Cheryl Hapke (Center Director, SPCMSC) was interviewed live on This Morning in America with Gordan Deal to discuss the potential impacts of Hurricane Matthew. The interview included discussion of potential beach erosion and what the USGS is doing to predict vulnerable areas in advance of the storm.

Seismic-reflection profile created by bouncing sound waves off sediment layers beneath San Pablo Bay, and variations in gravity caused by differences in rock density under the bay.Link between two earthquake faults near San Francisco, California, revealed by detailed sub-seafloor mapping

USGS scientists used a suite of complementary techniques to image sediment layers beneath San Pablo Bay, California, revealing an active fault beneath the bay that links two of the most urbanized and hazardous strike-slip faults in the San Francisco Bay area. The discovery, first announced December 2015 at the American Geophysical Union Fall Meeting, is detailed in “Missing Link between the Hayward and Rodgers Creek Faults,” published October 19, 2016, in Science Advances. Longer fault ruptures produce larger earthquakes, so understanding how fault segments connect with one another is critical to assessing the earthquake hazards they pose. This study demonstrates the importance of integrated, high-resolution mapping of sub-seafloor layers for characterizing the often-subtle deformations (as small as a few centimeters) where fault segments meet.
