The Free Ascending Tripod (FAT) designed and built at the USGS Pacific Coastal and Marine Science Center was recovered in late September after spending 5 months on the floor of the South China Sea collecting data with acoustic and optical instruments. FAT was deployed in April 2014 at 1,900 meters (6,200 feet) water depth in a cooperative project with scientists from Tongji University (Shanghai, China) to better understand how and where deep-seafloor sediment moves and accumulates. Discoveries from this project, one of only a few such studies conducted outside of the oil industry, will be at the forefront of deep-water marine-geology research for the region and probably for the world. Practical applications include choosing favorable sites for undersea cables and other infrastructure. Read about FAT at http://soundwaves.usgs.gov/2013/08/fieldwork2.html.

Photo of scientist remotely maneuvering camera system over seafloor.The USGS Marine Facility (MARFAC) in Santa Cruz, California, has developed a tethered instrument package called the Benthic OBservation Sled or “BOB Sled,” which can acquire video and other data as much as 700 meters (2,300 feet) below the sea surface. The system’s first use was in August–September 2014, when it collected imagery of the seafloor off Coos Bay, Oregon, in an area under consideration for the construction of a floating wind-energy facility. Designed for deployment from the 34-foot research vessel Parke Snavely, the system is remotely controlled from the vessel while it gathers data from multiple instruments that can be configured as needed for a particular science project. Video and data are transmitted and recorded on the surface vessel in real time. For more information, contact Gerry Hatcher, ghatcher@usgs.gov, 831-460-7524.


Coastal Defense Tool Wins United Nations Award

Illustration showing coastal defense.

Healthy tidal marsh (upper panel) reduces storm-wave heights, allowing levee to protect property. Degraded tidal marsh (lower panel) allows storm waves to erode and overtop levee.

The Coastal Defense app, a module of the Coastal Resilience Tool developed by The Nature Conservancy in collaboration with the USGS and other partners, received the top award for a scientific application addressing disaster and resilience planning at the September 23, 2014, United Nations Climate Summit in New York. Climate change is putting coastal communities at greater risk of erosion and flooding. The Coastal Defense app allows users to:

  1. identify areas at risk of coastal erosion and inundation from waves, sea-level rise, and storm surge,
  2. examine the role of coastal habitats—such as tidal wetlands—in attenuating wave height and energy, and
  3. determine adaptation strategies that incorporate natural as well as man-made protections.

USGS Scientist Briefs Office of Insular Affairs on Coral Reef Issues in the Pacific

Coral reef with wave breaking over it.

Underwater view of a wave crashing over a coral reef on the low-lying Kwajalein Atoll (Republic of the Marshall Islands) illustrates how healthy coral reefs cause waves to break offshore and dissipate their energy before reaching the shoreline, lessening the probability of coastal erosion and inundation.

USGS research geologist Curt Storlazzi briefed Lori Faeth, DOI's Acting Assistant Secretary for Insular Affairs, during the U.S. Coral Reef Task Force (USCRTF) meeting on Maui, Hawaiʻi, 8-13 September 2014. Storlazzi explained USGS research on coral reef health and sustainability for fisheries and shoreline protection. A recent study co-authored by Storlazzi shows that coral reefs provide substantial protection against natural hazards by reducing wave energy that would otherwise impact coastlines. He also discussed USGS efforts to understand the likely impacts of sea-level rise and climate change on freshwater and agriculture on low-lying Pacific atolls, some of which have already experienced saltwater flooding related to sea-level rise and changing climate. For more information, contact Curt Storlazzi, cstorlazzi@usgs.gov, 831-460-7521.

Scientists collecting sediment samples at Pillar Point, California, with a vibracorerGeologic Evidence of Past Tsunamis in California

By Bruce Richmond, Rick Wilson (California Geological Survey), Eileen Hemphill-Haley (Humboldt State University), and Bruce Jaffe

An extensive sedimentary deposit formed by a tsunami in 1946 was recently discovered at Pillar Point Marsh near Half Moon Bay, California. Although there were photos and eyewitness accounts of the tsunami and resulting damage at the time, finding the tangible evidence in the geologic record is an important part of assessing the long-term hazard that tsunamis pose to California coastal communities. A better awareness of tsunami potential will help local authorities devise improved mitigation and evacuation plans.

Studying Marsh Sediment and Drought in San Francisco Bay

Photograph of USGS crew recovering instruments from San Francisco Bay.Jessie Lacy and five other scientists from the USGS Pacific Coastal and Marine Science Center completed fieldwork to measure sediment delivery to marshes near China Camp State Park on San Pablo Bay, the northern extension of San Francisco Bay. From February 25–28, they recovered instruments that measured variations in suspended-sediment concentration in time and space, as well as current speed and direction, to determine transport of sediment. Because of the California drought emergency, they redeployed three instruments for longer term monitoring of salinity and suspended-sediment concentrations in San Pablo Bay. Results of the marsh studies will be used to improve models of marsh response to sea-level rise. The redeployed instruments will measure conditions during this serious drought, which could increase salinity and decrease suspended-sediment concentrations, owing to reduced freshwater flows.

USGS scientist provides tsunami animations for public broadcasting stories on Oregon earthquake and tsunami threats

Screen shot of an animation of a hypothetical tsunami triggered by a magnitude-9 earthquake in the Cascadia Subduction Zone.Eric Geist was contacted by Ed Jahn, reporter and producer of Oregon Public Broadcasting’s OPB NEWS/Oregon Field Guide, for animations of a hypothetical tsunami triggered by a magnitude-9 earthquake in the Cascadia Subduction Zone (off northern California, Oregon, Washington, and British Columbia). Jahn saw Geist’s original tsunami animations in an Oregon Department of Geology and Mineral Industries (DOGAMI) educational video. Geist revised the animations for Jahn, who will use them in several stories on the Cascadia Subduction Zone earthquake and tsunami threat to Oregon. For more information, contact Eric Geist, egeist@usgs.gov, 650-329-5457. [See larger version of graphic.]

Effects of dam removal on coastal and marine ecosystems

Photo of the estuarine environment near the mouth of the Elwha River.USGS ecologist and Mendenhall post-doc Melissa Foley continues to study how the removal of two dams on the Elwha River in Washington state is affecting coastal and marine ecosystems. Foley is working with biologists for the Lower Elwha Klallam Tribe to understand how changes in physical factors such as salinity, temperature, and turbidity affect biological productivity in estuaries near the river mouth, which have historically served as nursery habitat for juvenile salmon. In the nearshore, Foley is working with other USGS scientists to identify factors causing the loss of subtidal algae around the mouth of the Elwha River. Foley is measuring light availability, sediment deposition, and scouring frequency to determine if one or a combination of these factors is driving the marked decrease in algal cover since dam removal began in 2011. For more information, contact Melissa Foley, mfoley@usgs.gov, or 831-460-7564. Visit the "USGS Science to Support the Elwha River Restoration Project" web site at http://www.usgs.gov/elwha.


USGS Scientists Map Snohomish Delta, Washington

3-D image of the Snohomish Delta from swath bathymetry and acoustic backscatter data.To inform managers tasked with ecosystem restoration, salmon recovery, flood-hazard mitigation, and climate-change planning in Puget Sound, scientists from the Pacific Coastal and Marine Science Center are mapping the Snohomish Delta where data either do not exist or were last collected in the 1960s. Swath bathymetry and acoustic backscatter data will be merged with recent LiDAR data to generate high-resolution (1-meter) onshore-offshore digital-elevation and substrate models to characterize important salmon habitats, sediment budgets, and transport processes, and the effects of artificial levees. Many Pacific Northwest river-delta wetlands have lost habitat due to levees that focus stream flow and sediment offshore, leaving wetlands starved for sediment and vulnerable to sea-level rise while fragmenting nearshore seagrass meadows—both essential habitats for endangered salmon species. The data will provide important boundary conditions for hydrodynamic modeling. For more information, contact Eric Grossman, egrossman@usgs.gov, 206-526-2529.


Groundwater Studies on Kwajalein Atoll

High-tide at a groundwater sampling site on Roi Namur atoll, November 2013.Peter Swarzenski of the USGS Pacific Coastal and Marine Science Center will continue studies of the coastal aquifer of Roi Namur Island, Kwajalein Atoll, February 23–March 3, 2014. Swarzenski is investigating underground freshwater and saltwater using geochemical and geophysical techniques, including trace metal, nutrient, and carbon geochemistry; radon isotope analysis; piezometry; thermal conductivity; and electrical resistivity. This work is part of a joint study for the Department of Defense, Strategic Environmental Research and Development Program (SERDP) by USGS, NOAA, and the University of Hawaii, to assess impacts of sea-level rise and storm-wave inundation on infrastructure and freshwater under various sea-level rise and climate scenarios. DOD will use the findings to develop climate-change adaptation plans for infrastructure and water resources. The findings also will be useful to Pacific island nations threatened by sea-level rise and climate change. For more information contact Peter Swarzenski, pswarzen@usgs.gov, 831-460-7529.

Crown of thorns sea star, from the American Samoa National Park Service web site.Threats to Coral Reefs in American Samoa

USGS geologist Curt Storlazzi traveled to the National Park of American Samoa in mid-January 2014 to help the National Park Service address threats to coral reefs on the north side of the island of Tutuila. Threats include pollution caused by historical land-use practices, climate change (coral bleaching has occurred), outbreaks of crown-of-thorns sea stars (pictured here) that can kill coral reefs, and overfishing of grazers that suppress algal overgrowth caused by land-based pollution. Storlazzi also coordinated with academic, NOAA, and EPA scientists and American Samoa officials on research needs for the US Coral Reef Task Force priority study area at Faga'alu on the south side of Tutuila, where excessive land-based pollution threatens reefs. For more information, contact Curt Storlazzi, cstorlazzi@usgs.gov, 831-460-7521.


USGS Among Recipients of Prestigious DOI Partners in Conservation Award

Photograph of Nancy Prouty collecting water from the Niskin bottles on the CTD after deployment.The multiagency project “Bureau of Ocean Energy Management (BOEM) Atlantic Deepwater Canyons” is a recipient of the 2013 U.S. Department of the Interior’s Partners in Conservation Award. This study investigated the ecology of deepwater canyons off the U.S. mid-Atlantic coast—pathways for nutrients, sediments, and pollutants from the continental shelf to the deep sea about which little was previously known. Participants came from 17 organizations, including USGS, BOEM, NOAA, WHOI, several universities, private firms, and the North Carolina Museum of Natural Science. Principal USGS participants are Colleen Charles, Amanda Demopoulos, Cheryl Morrison, Christina Kellogg, and Nancy Prouty. Out of many nominations, only 20 partnerships were recognized in 2013 from all nine bureaus of DOI. The Secretary of the Interior presented the awards January 16, 2014, in Washington, D.C. For more information, contact Nancy Prouty, nprouty@usgs.gov, 831-460-7526.
