Coastal and Marine Geology Program
News stories for August 2013.
From September 4-6, Cheryl Hapke (USGS-St. Petersburg) has been invited to participate in the Board of Coastal Engineering Research meeting to be held in Long Branch, NJ. The purpose of the meeting, convened by the U.S. Army Corps of Engineers (USACOE), is to explore impacts on the water resources and infrastructure of the North Atlantic coastlines due to Hurricane Sandy. Research needs associated with sustaining resilient coastal communities and systems through risk reduction, regional sediment management, and ecosystem restoration activities will be discussed. On Thursday, Sept. 5, there will be discussions on the recovery from Hurricane Sandy including coastal breach closures, with which Cheryl has been actively involved in Fire Island, New York (see News items posted 2013-08-01 and 2013-07-24).posted: 2013-08-29
From 5-8 August, Sophia B. Liu, Ph.D., Mendenhall Post-Doc Fellow at the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC), participated in field experiments at the Joint Interagency Field Exploration (JIFX) event in Camp Roberts, CA at the McMillan Airfield. The Naval Postgraduate School (NPS) hosts these events several times a year to bring industry, academia, and government together in a semi-structured field testing environment fusing interactive community building and knowledge sharing activities with concept-based socio-technical experimentation. Dr. Liu's experiment titled "USGS 'Did the Coast Change?' Crowdsourcing Coastal Change Analysis of Aerial Photos" was one of over 60 experiments conducted at JIFX 13-4. With over 400 participants, her experiment focused on creating ad- hoc collaborations with participants developing similar geospatial crowdsourcing applications, social media analytics tools, and geospatial collaboration platforms. The following seven themes emerged as types of collaborations relevant to Dr. Liu's USGS geospatial crowdsourcing research: (1) Field-based crowdsourcing to ground truth remote crowdsourcing; (2) Harvesting social media for enhanced situational awareness and decision support; (3) Abstracting crowdsourcing workflows; (4) Visualizing and integrating crowdsourced data; (5) Emerging geospatial collaborations and platforms; (6) Imagery-related tools and projects; and (7) Innovation fellows and Hurricane Sandy-related project ideas.posted: 2013-08-29
Beaches and dunes on Fire Island, New York, lost more than half of their pre-storm volume during Hurricane Sandy, leaving the area more vulnerable to future storms.
While the damage and destruction on Fire Island was immediately evident after the storm, a new U.S. Geological Survey study released today is the first to quantify the actual changes to the coast caused by the storm.
"The beaches and dunes of the island were severely eroded during Sandy," said Cheryl Hapke, a USGS research geologist and lead author of the study. "The island was breached in three locations, and there was widespread damage and destruction of coastal infrastructure, including private residences. The report shows that the beaches and dunes lost 54.4 percent of their pre-storm volume, and the dunes experienced overwash along 46.6 percent of the island, dramatically changing the island's shape."posted: 2013-08-28
Interest is mounting in the possibility that gas hydratea naturally occurring ice-like substance that contains vast quantities of methanemight be a viable source of natural gas. A research cruise by the U.S. Geological Survey (USGS) Gas Hydrates Project in the northern Gulf of Mexico in spring 2013 shed new light on that possibility. The 15-day cruise was conducted by USGS scientists and technicians with partial financial support from the U.S. Department of Energy (DOE) and the U.S. Bureau of Ocean Energy Management (BOEM).posted: 2013-08-28
The U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management (CZM) have worked collaboratively to map the geology of the shallow seafloor offshore of Massachusetts coast. Interpretation of high-resolution geophysical data (interferometric and multibeam swath bathymetry, lidar, backscatter, and seismic reflection), sediment samples, and bottom photographs were used to produce a series of maps that describe the distribution and texture of seafloor sediments, shallow geologic framework, and physiographic zones of this inner-shelf region. These data and interpretations are intended to aid efforts to inventory and manage coastal and marine resources, and provide baseline information for research focused on coastal evolution and environmental change.
The link to the first CZM interpretive report, Shallow Geology, Seafloor Texture, and Physiographic Zones of the Inner Continental Shelf from Nahant to Northern Cape Cod Bay, Massachusetts, is available at http://pubs.usgs.gov/of/2012/1157/posted: 2013-08-27
USGS scientists working with partners from NOAA, BOEM, CSA Ocean Sciences, and universities are completing the final fieldwork of the 4-year Deepwater Canyons project to investigate biology, geology, oceanography, and archeology (shipwrecks) in two mid-Atlantic canyons off Virginia and Maryland. This cruise on the NOAA ship Nancy Foster departed from North Charleston, SC, on August 21 and will return August 28. Amanda Demopoulos, Olivia Cheriton, and Jonathan Borden from USGS are retrieving deep-sea moorings with rotating sediment traps and benthic landers with instruments and deep-sea coral experiments, all deployed August 2012. Demopoulos is project chief of the multidisciplinary USGS Diversity, Systematics and Connectivity of Vulnerable Reef Ecosystems (DISCOVRE) project, which studies the biology, ecology, and connectivity of deep-sea coral environments to provide the science needed for their effective conservation and management.

Christina Kellogg (USGS-St. Petersburg) will be traveling to Norway (September 2-7, 2013) to continue a collaborative study on the effects of drilling mud on cold-water corals. Kellogg is a participant in a three year study funded by the Research Council of Norway and will be consulting on experimental design and microbial ecology. A primary objective of this project is to develop diagnostic methods to detect cold-water coral stress that may result from nearby oil and gas exploration activities.

Nathaniel Plant (USGS-St. Petersburg) and Wayne Wright (USGS-Salisbury, MD) attended the Annual Airborne Coastal Mapping and Charting workshop on lidar technology and applications hosted by the Joint Airborne Lidar Bathymetry Technical Center of Excellence (JALBTCX), held 6-7 August in Mobile, AL. The meeting included technical and scientific expertise from federal, academic, and commercial institutions. USGS presented updates of improved bathymetric lidar capabilities and gave examples of applications of topographic and bathymetric lidar.posted: 2013-08-22
Beginning Saturday August 17 and running for three Saturdays in a row, the Weather Channel will feature a series "Breaking Ice" on the 2012 expeditions of the Healy. USGS scientist Lisa Robbins (St. Petersburg) led one of the science missions on the 2012 Healy cruise looking at Arctic Ocean Acidification. The team worked alongside scientists mapping the seafloor as part of the U.S. Extended Continental Shelf program. The 6-part series compares the experiences of the U.S. Coast Guard Healy in the Arctic with the German civilian R/V Polarstern in the Antarctic. This week's episode, Iced, (8/24/13, 9:00-9:30 pm EDT) shows the American icebreaker Healy reaching the northernmost section of its 5-week Arctic mapping mission.posted: 2013-08-22
Plans for remapping parts of the East Coast where Hurricane Sandy altered seafloors and shorelines, destroyed buildings, and disrupted millions of lives last year are being announced today by three federal agencies. This remapping plan comes one day after the Administration's Hurricane Sandy Rebuilding Task Force progress report.
The USGS, NOAA, and the U.S. Army Corps of Engineers are using emergency supplemental funds provided by Congress to survey coastal waters and shorelines, acquiring data that will update East Coast land maps and nautical charts.
Using ships, aircraft, and satellites, the agencies will measure water depths, look for submerged debris, and record altered shorelines in high priority areas from South Carolina to Maine, as stipulated by Congress in the Disaster Relief Appropriations Act of 2013.
The areas to be remapped will be based on their relative dangers to navigation, effects from the storm, and discussions with state and local officials as well as the maritime industry.

The NOAA research vessel Okeanos Explorer has been live-streaming the video feed from their remotely-operated vehicle (ROV) during exploratory dives in the deepwater canyons off the coast of the northeastern United States. Amanda Demopoulos (USGS-SESC) is co-leading the cruise during August with Martha Nizinski (NOAA) and interfacing with a team of shore-based scientists, including Christina Kellogg (USGS-SPCMSC). While promoting the cruise on Twitter, Kellogg coined the phrase "Deep Sea TV" to describe the live video feed. The Associated Press (AP) picked up the theme and wrote a story about the telepresence cruise, framing it in terms of a reality TV show. The story has been picked up by ABC, NBC, Yahoo News, USA Today, Washington Post, and many regional newspapers. As many as 67,000 viewers have logged on during a single dive to watch the live feed of the sea floor hundreds of meters below the surface. Deep Sea TV continues through August 16th, so skip the summer reruns and join the exploration!

Three new USGS products in an ongoing series by the California Seafloor Mapping Program (CSMP) were released August 9th, 2013a map set for the area offshore of Carpinteria in southern California, a catalog of geographic-information-system (GIS) data layers for all of CSMP's published maps, and a collection of videos and photos of the seafloor along the entire California coast. The USGS is a key partner in the CSMP, a collaboration between state and federal agencies, academia, and the private sector to create a comprehensive base-map series for all of California's state waters. With the new products, decision makers and elected officials can better design and monitor marine reserves, evaluate ocean energy potential, understand ecosystem dynamics, recognize earthquake and tsunami hazards, regulate offshore development, and improve maritime safety.posted: 2013-08-09
On July 31, Amy Keller of Florida Trend Magazine inquired about the USGS St. Petersburg Coastal and Marine Center for a forthcoming article on the "Marine High Tech Corridor" in the Tampa area. While the print version of the magazine will publish all the articles at once, the online version releases articles sporadically, so the article may not be immediately available online.posted: 2013-08-01
On July 24, USGS Geologist Cheryl Hapke had a phone briefing with Dave Wegner, senior Democratic staffer from the House Subcommittee of the greater Committee on Transportation and Infrastructure about the breach in Fire Island, NY, caused by Hurricane Sandy. The call was in response to the briefing that Cheryl and Dave Russ had given to Senator Schumer's (D-NY) staff on July 17. Mr. Wegner stated that he was getting conflicting information about whether the breach is naturally closing or if it has grown to such a size that it will not allow for natural closure. Cheryl stressed that it is inconclusive whether the breach is opening or closing, but that the USGS has recently collected data, in collaboration with the U.S. Army Corps of Engineers, and is planning to conduct additional analyses. Mr. Wegner also asked about the USGS activities in response to Hurricane Sandy and about the longer-term research the USGS is conducting at Fire Island. Cheryl mentioned that an Open-file Report on Hurricane Sandy coastal impacts should be published by the fall. Mr. Wegner was appreciative of the information exchanged and wants to revisit the possibility of more conversations after the Open File Report is published.posted: 2013-08-01
On July 26, the USGS (St. Petersburg) received a query from a reporter about the nature of the offshore ledges near Ft. Myers, Fl. Kevin Lollar, who works for the News-Press was inquiring about the origin of ledges divers commonly encounter offshore. Chris Reich (Geologist) spoke with Mr. Lollar and suggested that most ledges encountered by casual divers were likely natural limestone exposures that were eroded at the shoreline when sea level was lower, rather than formed by coral reefs. There are many of these ledges and rock outcrops along the west Florida shelf, some in water too deep to fully understand their genesis, but a new discovery by the USGS working on the geology of the Florida Middle Ground showed that a marine gastropod helped preserve the structures that are used by many divers and fisherman today.
