On 3/27, USGS staff Cheryl Hapke and Owen Brenner travel to Long Island, NY to attend the Fire Island Biennial Science meeting held at the Fire Island National Seashore Management Center in Patchogue, NY. Cheryl is giving an invited presentation at the two-day conference. Cheryl and Owen will also meet with National Park Service staff to discuss ongoing field activities.posted: 2014-03-27
From 3/29–4/7, USGS scientist Cheryl Hapke will travel to Delft, Netherlands, to meet with various researchers at the Deltares Institute and the Delft University of Technology (TU Delft) to collaborate on a joint Hurricane Sandy Supplemental funded effort to develop a morphologic evolution model of the breach at Fire Island that formed during the landfall of Hurricane Sandy in Nov. 2012.posted: 2014-03-27
From 3/24 to 4/7, USGS staff will be collecting sediment samples (marsh push cores, sand auger cores, and surface and estuarine grab samples) from Assateague Island, Chincoteague Bay, MD and VA. The primary purpose of the sampling is to characterize the surficial sediment of sandy washover fans and back-barrier marshes and then integrate the data into vulnerability assessments for the Barrier Island and Estuarine Wetland Physical Change project. In addition, the sediment data will be used to establish a baseline dataset and will be integrated into estuarine models being developed for the Estuarine Physical Response project.posted: 2014-03-20
The limited invitation meeting includes Federal and State resources mangers, scientists, and policymakers, Gulf academic scientists, key nongovernmental organizations and leaders. USGS scientists Alyssa Dausmon and Jack Kindinger are attending to participate in discussions on science-based restoration current and future directions. The meeting is being held in Houston, TX, March 24th to 27th.posted: 2014-03-20
On March 27th, USGS oceanographer Joseph Long will give an invited presentation on the USGS National Assessment of Coastal Change Hazards program at the 29th Annual Symposium on Caribbean Geology held at the University of Puerto Rico in Mayaguez, PR.

On March 11, the Coastal and Marine Geology Program (CMGP) announced that it's new dynamic ocean and coastal program 'front end' web pages were live. The modern looking pages are the result of a team effort to analyze CMGP web content and to develop a strong, yet flexible, information architecture that provides a front door entry to our information. The new information architecture moves CMGP much closer to meeting mandates from Department of Interior (DOI) and the White House.

The inner continental shelf off the northern Outer Banks of North Carolina was mapped using sidescan sonar, interferometric swath bathymetry, and high-resolution chirp and boomer subbottom profiling systems. This information was used to describe the shallow stratigraphy, reinterpret formation mechanisms of some shoal features, evaluate local relative sea-levels during the Late Pleistocene, and provide new constraints, via recent bedform evolution, on regional sediment transport patterns.

From March 10-14, USGS Researchers Joe Long and P. Soupy Dalyander are collaborating with the Sediment Dynamics Laboratory at the Naval Research Laboratory, Stennis Space Center, MS, to observe how Surface Residual Balls (SRB's) are transported in the nearshore environment. SRB's are sand-oil agglomerates that were formed/deposited in coastal environments following the Deepwater Horizon oil spill. These measurements are the first of their kind and will be taken in a large-scale flow tank to observe if, how, and when SRBs move due to steady and oscillatory currents.posted: 2014-03-10
In a collaborative effort with National Oceanic and Atmospheric Administration-National Geodetic Survey, USGS lidar operations staff will map off the coast of St. Thomas, U.S. Virgin Islands, as well as near Buck Island National Wildlife Refuge. From approximately March 3–17, USGS scientists and staff will support mapping efforts for the USGS's EAARL-B (Experimental Advanced Airborne Research Lidar) lidar system. One of the unique features of the EAARL-B system is its ability to map both exposed and submerged topography to provide a continuous map of near-shore environment. Based upon test flights over typical Caribbean coral reef environments, the original EAARL demonstrated penetration to greater than 25 m, and routinely mapped coral reefs ranging in depth from 0.5 to 20 m below the water surface. The new EAARL-B is expected to surpass its predecessor with nominal offshore visibility in the Virgin Islands normally peaking in March.

The U.S. Geological Survey (USGS) Coastal Change Processes Project is conducting a field experiment on the inner continental shelf offshore of Fire Island, New York to study the coastal response to storms. Starting in early February 2014, scientists from the USGS Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts, along with scientists from the Woods Hole Oceanographic Institution and the University of South Carolina, deployed oceanographic equipment at nine sites in water depths of approximately 12 meters (40 feet), with one site farther offshore at a of approximately 25 meters (80 feet). An ocean buoy was deployed at this offshore site to measure surface waves and telemeter the data via an iridium connection for analysis.
The data are available as part of the Coastal Data Information Program (CDIP) program at http://cdip.ucsd.edu/
In addition to the scientists, the data are being used by the U.S. Coast Guard, the National Park Service, and locals such as surfers http://www.surfline.com/surf-reportThe buoy is expected to remain on site for several years.posted: 2014-03-10
