On July 17, approximately 20 campers and counselors from the Orlando Science Center summer camp visited the USGS SPCMSC center. Organized by Monica Cook from the University of South Florida (USF) College of Marine Science, the visit to USGS is part of a day-long tour of the USGS/USF facilities in St. Petersburg. Kara Doran (SPCMSC Oceanographer) spoke to the middle school students about USGS barrier-island research at the center, and ended her talk by sharing personal stories about her experiences measuring beach erosion at the Kennedy Space Center.posted: 2014-07-24
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.posted: 2014-07-17
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.posted: 2014-07-17
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.posted: 2014-07-10
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.posted: 2014-07-10
Hydrologists in the USGS Water Mission Area held a training class at the Woods Hole Coastal and Marine Science Center and nearby Quashnet River on "Field Techniques for Groundwater/Surface-Water Interactions" from June 9 through 13. The inaugural field class drew 35 scientists and students from across the country to learn several traditional and emerging techniques to characterize the locations, rates, and chemical quality of groundwater discharge to streams, lakes, and coastal zones. USGS scientists were joined in the class by researchers and students from the Massachusetts Division of Fisheries and Wildlife, University of Massachusetts-Amherst, Mount Holyoke College, and Oregon Water Resources Department.
Students and instructors spent two days along the Quashnet River in Mashpee and Falmouth participating in demonstrations and experiments that are anticipated to improve the understanding of the links between groundwater discharge to the river and the ecology of the river's Brook Trout population. The experiments included direct measurements of groundwater discharge with seepage meters, groundwater-head measurements with temporary streambed piezometers, streamflow and groundwater temperature measurements with fiber-optic cables laid along the river's streambed, and stream tracer tests to monitor surface-water and groundwater exchange rates. Data collected along the river were analyzed by the class on Thursday and Friday at the Science Center's Tilley Conference Room.
Groundwater exchange with surface waters is an important research and applied-science activity of the USGS that is motivated by the many environmental and water-resource management challenges that result from the complex hydrologic and chemical interactions that occur at the interface between surface and subsurface waters.posted: 2014-07-08
On June 25, the field team obtaining shallow water bathymetric data from jet-skis as part of the Hurricane Sandy Supplemental Funding effort returned from their fieldwork in Fire Island, New York. The mapping effort was very successful and the team, which included personnel from both the Santa Cruz and St. Petersburg Science Centers, acquired almost twice the amount of data that had been originally been tasked. Members of the team also mapped portions of the flood shoal of the Sandy breach on foot to collect data in water that was too shallow for the jet-skis. Coastal and Marine Geology staff participating in the data operations include Cheryl Hapke, B.J. Reynolds, Owen Brenner, Dave Thompson, Tim Nelson, Kyle Kelso, Andrew Stevens, Tim Elfers and Jackson Currie.

From July 7–17, researchers from the USGS will be engaged in integrated data and sample collection at Crocker Reef in the Florida Keys as part of the Coastal and Marine Geology Program's Coral Reef Ecosystem Studies (CREST) project. Reefs are complex ecosystems where environmental and biological factors are constantly affecting each other, creating a heterogeneous and ever-changing landscape on both spatial and temporal scales. We are combining expertise in three specific areas (geochemistry, geology, and metabolic processes) to better characterize the processes that affect carbonate precipitation and dissolution. This effort will combine sediment sampling for mineralogy with water sampling for carbonate chemistry and reef metagenome analyses. This summer sampling trip will be followed by another collection trip in December/January to capture seasonal variation. Understanding the processes that underlie whether the reef is accreting (growing) or dissolving is fundamental to questions of reef health and resiliency. Principal investigators are Christina Kellogg (metagenomes), Kim Yates (carbonate chemistry) and David Zawada (sediments). Assisting on this field trip are Chris Moore, Nathan Smiley, and Molly McLaughlin.posted: 2014-07-02
On July 8th, Joseph Long will present a talk entitled 'Online; on-demand access to coastal digital elevation models (DEMs)' at the Earth Science Information Partners (ESIP) Summer Meeting in Frisco, Colo. The project is part of the 2014 USGS Community for Data Integration projects, and aims to build an online tool to construct DEMs that span the terrestrial/marine boundary for use in numerical models and coastal change research.
