On July 3, 2014, USGS researchers published an article, Modification of the Quaternary stratigraphic framework of the inner-continental shelf by Holocene marine transgression: An example offshore of Fire Island, New York, by Schwab and others, in Marine Geology.
In this paper, maps of the geometry and structure of the Quaternary sedimentary deposits offshore of Fire Island are presented. These maps and geophysical data are used to form a conceptual model of the Holocene evolution of the inner-continental shelf and shoreface, a consequence of marine transgression of Pleistocene glaciofluvial sedimentary deposits.

In June, 2014, Lauren Toth joined USGS-St. Petersburg as a Mendenhall Post-Graduate Fellow. Lauren will be working with coral ecologist Ilsa Kuffner on the CREST project (Coral Reef Ecosystem Studies) looking at corals from the USGS-St. Petersburg drill core collection. She will be analyzing the rates of reef accretion to understand why some reefs had slower rates of growth over the last 4000 years. Lauren will be utilizing the ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometer) to look at geochemistry of the corals in the drill core sections to understand not only changes in reef development, but also changes in the environment of the reefs through time.
On July 16, the USGS released Data Series 767, "The EAARL-B Coastal Topography - Eastern New Jersey, Hurricane Sandy, 2012: First Surface." This publication provides geographically referenced elevation measurements of lidar-derived first-surface (FS) topography for a portion of the New Jersey coastline beachface, acquired pre-Hurricane Sandy on October 26, and post-Hurricane Sandy on November 1 and November 5, 2012. The datasets are made available for use as a management tool to research scientists and natural-resource managers.
On June 25 and 26, thirty 8th grade students attending University of South Florida (USF) College of Marine Science's (CMS) Oceanography Camp for Girls visited the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC) to learn about how hurricanes and other extreme storms impact our coastline. Kara Doran simulated a hurricane using the Center's coastal erosion model, which illustrates how wind and waves transport sediment from a barrier island during storms. Fifteen students also had the opportunity to interview Center scientists one-on-one about their work. Participating St. Petersburg SPCMSC and Southeast Ecological Science Center (SESC) scientists included Kara Doran, Alisha Ellis, Jennifer Flannery, Caitlin Reynolds, Julie Richey, Lisa Robbins, Jaci Smith, Tom Smith, and Lauren Toth.
From July 11th to the 31st, SPCMSC geologists Jim Flocks and Jen Miselis will lead a major field expedition to the Breton and Chandeleur Islands, part of the Breton National Wildlife Refuge, offshore of the Mississippi River Delta. The first of two field efforts at the Refuge this summer, the team will deploy from Venice, La., and Biloxi, Ms., and remain at the islands for the duration of the survey. The fieldwork will gather shallow-water bathymetry, near-surface geology, and island elevation using the R/V Sallenger among other vessels. SPCMSC staff participating in the field work include Julie Bernier, Trevor Browning, Nancy DeWitt, Jake Fredericks, Kyle Kelso, Stan Locker, BJ Reynolds, and Dana Wiese.
