USGS tidal flow monitoring station at little egg inlet, nj.Geologic Mapping of Barnegat Bay, NJ

The USGS, in collaboration with the New Jersey Department of Environmental Protection (NJ DEP) and the Barnegat Bay Partnership, has successfully completed a 2-year effort to characterize the physical environment of Barnegat Bay-Little Egg Harbor Estuary. The primary goal of the study was to improve understanding of the causes behind degraded water quality in the bay. Over 2000 kilometers (>1200 miles) of data were collected using boat-based acoustic sensors that measure depth and the composition and distribution of the sediments within the bay. Data from acoustic sensors were combined with data from airborne optical sensors to create a complete picture of bay depth, one of the first efforts of its kind in a shallow estuary. In late 2012, the landfall of Hurricane Sandy heavily impacted the study area. However, data collected before and after this storm as part of this project will help scientists understand the impact of the storm on the water quality, sediments, and habitats within the bay.

The March 11, 2011 Tohoku-oki tsunami caused significant damage to ships and docks within Crescent City Harbor in California. A number of ships were sunk within the harbor.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.

icebreaker healyIcebreaker Cruise Measures Arctic Greenhouse Gases

The USGS Gas Hydrates Project will measure the concentrations of methane and carbon dioxide in near-surface waters and at multiple vertical levels in the atmospheric marine boundary layer aboard the USCG icebreaker Healy in October 2013. Cavity ring-down spectroscopy and other instrumentation will constrain ocean-atmosphere methane and carbon dioxide fluxes in real-time along a 4000-km-long roundtrip route from the Bering Strait through the US Beaufort Sea and east to the Amundsen Gulf. The data will be used to assess the hypothesis that the Arctic region is undergoing rapid leakage of methane in response to global warming and will provide unprecedented information about pan-Western Arctic greenhouse gas dynamics.

R/V Centennial with crewUSGS and UW extract long sediment cores from Hood Canal to examine natural versus anthropogenic controls on marine ecosystem stressors

During mid-September 2013, researchers from the USGS Pacific Coastal and Marine Science Center (PCMSC), the USGS St Petersburg Science Center, St Petersburg, Florida (SPCMSC), and the University of Washington (UW) conducted a research cruise aboard the R/V Centennial (http://depts.washington.edu/fhl/fac_RVCentennialSpecifics.html) to Lynch Cove, WA, the terminus of Hood Canal in Puget Sound. Parts of Hood Canal and Lynch Cove suffer periodic depletions in bottom water oxygen (hypoxia), which can negatively affect ecosystem health. While delivery of terrigenous constituents that contribute to low bottom water oxygen are likely enhanced by decades of widespread urbanization, agriculture, and silvaculture, this research was directed at decoupling natural from anthropogenic controls on such ecosystem stressors.

Sampling included a series of 16 Van Veen surface sediment grab samples and and five long sediment kasten cores. Lisa Osterman (USGS-St. Petersburg, Fl) will examine subsets of foraminifera as tracers of low oxygen events. Additional analyses including grain size, C, N concentration and isotopes, redox-sensitive trace elements such as vanadium, rhenium, and uranium, and sterol, lignin phenol biomarkers, along with the foraminifers may resolve historic low oxygen events from modern processes and may also provide insight into how climate change may impact ecosystem health in this fjord.

The USGS, in collaboration with the Ocean Exploration Trust, the University of Puerto Rico, and the Scripps Institute of Oceanography, is conducting a multidisciplinary research cruise in the northeast Caribbean Sea between October 4-18 2013, aboard the ship E/V Nautilus. The primary goal is to better understand the timing of tectonic activity along submarine fault systems, such as those responsible for the 1842 earthquake in Hispaniola, the 1918 earthquake in western Puerto Rico, and the 1867 earthquake in the Virgin Islands. Dives will be carried out with the remotely operated vehicle (ROV) Hercules, equipped with high-definition video cameras that will investigate: 1) submarine landslide scars that either failed recently (1918) or may fail in the near future, 2) biological diversity in this totally unknown region, and 3) the existence of an oceanographic intermediate-depth water flow from the Atlantic to the Caribbean. The expedition will be broadcast live to numerous schools, boys and girls clubs and science museums around the country. Contact: Uri ten Brink, utenbrink@usgs.gov

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.

Unprecedented Rate and Scale of Ocean Acidification Found in the ArcticUnprecedented Rate and Scale of Ocean Acidification Found in the Arctic

Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLOS ONE. The increase in rate is being blamed on rapidly melting sea ice, a process that may have important consequences for health of the Arctic ecosystem.

Ocean acidification is the process by which pH levels of seawater decrease due to greater amounts of carbon dioxide being absorbed by the oceans from the atmosphere. Currently oceans absorb about one-fourth of the greenhouse gas. Lower pH levels make water more acidic and lab studies have shown that more acidic water decrease calcification rates in many calcifying organisms, reducing their ability to build shells or skeletons. These changes, in species ranging from corals to shrimp, have the potential to impact species up and down the food web.

Photograph of the research vessel Alaskan Gyre.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. For more information contact Tom Parsons, tparsons@usgs.gov, 650-329-5074.

Patrick Barnard surveying offshore in the Rincon focus area, on a personal watercraft.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.
