Coastal Surveys near Santa Barbara, California
USGS Pacific Coastal and Marine Science Center personnel will survey beaches and the nearshore ocean from Point Conception to Mugu Canyon, October 3-10, 2013. Walking, all-terrain vehicle, and personal watercraft GPS surveys will provide precise measurements of beach topography and nearshore bathymetry, adding to a 26-year record of surveys in the area. Long-term data show no major trends in erosion or deposition, except around the Santa Clara River mouth where flood deltas and subsequent erosion can cause shoreline change on the order of 100 meters. Surveys in focus areas show shoreline oscillations of 20-30 meters between winter (erosion) and summer (accretion), and net west-to-east alongshore sediment transport. Morphological analyses suggest that alongshore transport is only one-fifth of that estimated from harbor dredging records (Patsch and Griggs 2008, Marine Geology), likely due to the complex and intermittent transport regime and to overestimation by the dredging record approach.

USGS and Collaborators Release Report on Hypothetical Alaskan Tsunami and Its Likely Impacts on the California Coast
A new report, Science Application for Risk Reduction (SAFRR) Tsunami Scenario, presents a hypothetical yet plausible scenario in which a magnitude 9.1 earthquake off Alaska triggers a tsunami that reaches California. In this scenario, approximately three-quarters of a million people—about a third of them tourists and visitors—would need to be evacuated in just a few hours. Additionally, one-third of the boats and more than half of the docks in California's marinas could be damaged or destroyed, resulting in $700 million in losses. The highest waves would be in central and northern California, but much of the damage would occur in southern California's numerous marinas and large port facilities. Economic losses in California due to physical damage and business interruption would range from $5-10 billion, depending on resilience strategies. Neither of the State's nuclear power plants would likely be damaged by this particular event. The scenario was the focus of workshops led by USGS scientists and partners in California coastal communities September 4–10, 2013, in partnership with the California Tsunami Hazard Mitigation Program. Read the multichaptered report; view a 4-page USGS Fact Sheet; and learn about other SAFRR projects. For more information, contact Stephanie Ross, firstname.lastname@example.org, 650-329-5326.

Molasses Spill and Fish Kill in Honolulu Harbor, Hawaii
USGS marine scientists Mike Torresan (geologist) and Dave Cacchione (emeritus oceanographer) were interviewed by CNN about a massive molasses spill that occurred in Honolulu Harbor, Hawaii, on September 9, 2013, killing numerous fish and other sea life. They were cited in the report posted on September 12 at http://www.cnn.com/2013/09/12/us/hawaii-molasses-spill/. Torresan explained that the molasses suffocated fish by displacing oxygen-rich water, and Cacchione noted that unusually high tides expected later in the week could help speed dispersal of the molasses. For more information, contact Mike Torresan, email@example.com, 831-460-7425.
Studying Tsunami Sources Near Valdez, Alaska
USGS personnel from the Pacific Coastal and Marine Science Center, the Woods Hole Coastal and Marine Science Center, and the Alaska Science Center will look for sub-seafloor records of earthquakes, landslides, and tsunamis near Valdez, Alaska, including the 1964 magnitude 9.2 earthquake and tsunami. The 1964 tsunami was the most destructive in Alaska history and also impacted Canada and the U.S. west coast. Chirp and multichannel seismic-reflection systems on the USGS research vessel Alaskan Gyre will be used for surveys in Port Valdez September 3-13, 2013. Goals include (a) determining whether 1964 slope failures collapsed as contiguous blocks or broke up into debris flows, and (b) looking for buried evidence of previous earthquakes, landslides, and tsunamis. More accurate tsunami-source models benefit NOAA, FEMA, NRC, coastal-state geologic agencies, reinsurance companies, local emergency responders, shipping/transit agencies, and energy-delivery agencies.

Update -- USGS Biologists Discover New Chemosynthetic Communities on Interagency Deepwater Canyons Cruise
On May 8, USGS biologists on board the joint USGS/BOEM/NOAA and university expedition "Deepwater Canyons 2013 - Pathways to the Abyss" discovered vast beds of deep sea chemosynthetic mussels over a mile deep in Deepwater Canyons of the coast of the Atlantic. The new community was found in a gas seep site being visited for the first time. Bathymetric data collected on a previous expedition had suggested, based on bubbles rising through the water columns, that this may be the site of a previously undiscovered gas seep. This discovery confirmed the presence of a seep and an associated biological community. The information was posted on the expeditions' blog hosted by NOAA at http://oceanexplorer.noaa.gov/explorations/13midatlantic/logs/may8/may8.html and was tweeted from @USGS and @USGSAquaticLife. For more information, contact Helen Gibbons at 831-460-7418, email@example.com or Rachel Pawlitz at 352-264-3554, firstname.lastname@example.org.

Deep-Ocean Mineral Deposits as Source of Critical Metals
USGS scientists James Hein, Kira Mizell, and Tracey Conrad, with colleague Andrea Koschinsky of Jacobs University Bremen (Germany), just published "Deep-ocean mineral deposits as a source of critical metals for high- and green-technology applications: comparison with land-based resources" in the June 2013 issue of Ore Geology Reviews. Ferromanganese (Fe-Mn) crusts and nodules on the ocean floor are enriched in rare and critical metals and rare-earth elements, many of which are essential for high-tech, green-tech, emerging-tech, and energy applications. The authors compare the grades and tonnages of nodules and crusts in two areas of the Pacific Ocean with global terrestrial reserves and resources. They also discuss differences between terrestrial and marine impacts and mine characteristics. Deep-ocean mineral deposits will not replace land-based mining but will offer an additional source of raw materials to meet increasing demands. (James Hein, Santa Cruz, CA, 831-460-7419)
