USGS Will Explore Caribbean Seamounts
NOAA’s Office of Exploration and Research has approved a proposal by USGS scientists to explore seamounts off Puerto Rico and the Virgin Islands for two weeks in September 2014. The scientists will sail on the Ocean Exploration Trust’s exploration vessel Nautilus along with colleagues from other agencies and universities. Using the ship and a remotely operated vehicle (ROV), they will acquire multibeam and subbottom data; characterize the seamounts’ geomorphology and geology; describe the abundance, composition, distribution, and food-web ecology of fishes and invertebrate communities, including deep-sea corals; measure water-mass properties, such as temperature, salinity, dissolved oxygen, and currents; and determine habitat specificity of fauna associated with seamount environments. Live video from the ship and ROV will enable some to participate by telepresence. For more information, contact lead-P.I. Amanda Demopoulos, email@example.com, 352-264-3490, or (in the Pacific Region) Nancy Prouty, firstname.lastname@example.org, 831-460-7526.

USGS a Key Contributor to Tsunami Preparedness Exercises
As part of National Tsunami Preparedness Week, March 23 to 29, the San Francisco [California] Department of Emergency Management is conducting a 3-day functional exercise to practice the city’s tsunami alert and warning procedures, response capabilities, and recovery operations. USGS marine geophysicist Stephanie Ross is representing the USGS at this exercise, which is based on the SAFRR Tsunami Scenario developed by USGS scientists and collaborators and released September 2013. NOAA's annual PACIFEX tsunami-warning exercise on March 27 is also based on the SAFRR Tsunami Scenario. Some of the organizations and communities holding PACIFEX-related exercises include Washington State and California's San Mateo, Marin, and Orange Counties. The National Institutes of Health will hold a recovery-phase exercise on April 7. For more information, contact Stephanie Ross, email@example.com, 650-329-5326.
USGS Participates in Public Tsunami Preparedness Walks
As part of National Tsunami Preparedness Week, March 23 to 29, many coastal communities are holding Tsunami Walks, starting at the coast and walking uphill out of the expected inundation zone. Stephanie Ross, USGS marine geophysicist and coordinator of the SAFRR Tsunami Scenario, will represent the USGS at the San Francisco Tsunami Walk on Saturday, March 29, which begins at 10:30 a.m. on the Marina Green (at Marina and Scott). During this free public event (see event web page), participants will simulate an actual tsunami evacuation, walking away from San Francisco Bay toward higher ground (the Marina Branch Library at Chestnut and Webster). In California, other tsunami walks are being held in Crescent City, Muir Beach, Huntington Beach, Seal Beach, and San Diego. For more information, contact Stephanie Ross, firstname.lastname@example.org, 650-329-5326.
USGS Paleontologists Will Participate in “BioBlitz” Species Inventory
USGS paleontologists Mary McGann and Scott Starratt will participate in an all-taxa species inventory on March 28–29, 2014, in California’s Golden Gate National Recreation Area. During the “BioBlitz”—sponsored by the National Geographic Society and the National Park Service—teams of volunteers led by expert scientists will find and identify as many species as possible within a 24-hour period. McGann (Pacific Coastal and Marine Science Center) and Starratt (Volcano Hazards Program) will sift through San Francisco Bay-floor sediment to identify foraminifera (McGann) and diatoms (Starratt), one-celled organisms that make shells of calcium carbonate and silica, respectively. These shells can provide information about present ecosystem health and past climate and oceanographic conditions. One BioBlitz goal is to create broader impacts through public outreach, science education, and media coverage of this scientific endeavor. For more information, contact Mary McGann, email@example.com, 650-329-4979.
Studying Marsh Sediment and Drought in 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. For more information contact Jessie Lacy, firstname.lastname@example.org, 831-460-7520.
USGS research geophysicist contacted about tsunami potential of the Cascadia Subduction Zone
Eric Geist was contacted regarding how tsunamis generated by the Cascadia Subduction Zone (off northern California, Oregon, Washington, and British Columbia) could affect the U.S. west coast. The questions followed a magnitude-6.8 earthquake that occurred offshore of northern California on March 9, 2014 (local time). The earthquake occurred in the Gorda subplate, a tectonic plate that is subducting beneath the Pacific Northwest at a rate of about 23 millimeters/year. Los Angeles Times staff writer Rong-Gong “Ron” Lin II interviewed Geist, and KTVU meteorologist Mark Tamayo contacted him for information (no interview). For more information, contact Eric Geist, email@example.com, 650-329-5457.
USGS scientist provides tsunami animations for public broadcasting stories on Oregon earthquake and tsunami threats
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, firstname.lastname@example.org, 650-329-5457. [See larger version of graphic.]

Effects of dam removal on coastal and marine ecosystems
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, email@example.com, 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
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, firstname.lastname@example.org, 206-526-2529.
Groundwater Studies on Kwajalein Atoll
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, email@example.com, 831-460-7529.

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.
