Sediment transport in a restored, river-influenced Pacific Northwest estuary
Predicting the success of future investments in coastal and estuarine ecosystem restorations is limited by scarce data quantifying sediment budgets and transport processes of prior restorations. This study provides detailed analyses of the hydrodynamics and sediment fluxes of a recently restored U.S. Pacific Northwest estuary, a 61 ha former...
Nowacki, Daniel J. ; Grossman, Eric Submarine canyons, slope failures and mass transport processes in southern Cascadia
The marine turbidite record along the southern Cascadia Subduction Zone has been used to interpret paleoseismicity and suggest a shorter recurrence interval for large (>M7) earthquakes along this portion of the margin; however, the sources and pathways of these turbidity flows are poorly constrained. We examine the spatial distribution of...
Hill, Jenna C.; Watt, Janet; Brothers, Daniel; Kluesner, Jared A 4000-year history of debris flows in north-central Washington State, U.S.A.: Preliminary results from trenching and surficial geologic mapping at the Pope Creek fan
Long-term records of the magnitude and frequency of debris flows on fans are rare, but such records provide critical information needed for debris-flow hazard and risk assessments.

U.S. West Coast and Alaska Marine Geohazards
Marine geohazards are sudden and extreme events beneath the ocean that threaten coastal populations. Such underwater hazards include earthquakes, volcanic eruptions, landslides, and tsunamis.
Devastating earthquakes in Japan (2011) and Chile (2010) that spawned pan-oceanic tsunamis sent a sobering reminder that U.S. coastlines are also vulnerable to natural disasters that originate in...
Remote Sensing Coastal Change
We use remote-sensing technologies—such as aerial photography, satellite imagery, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.
Estuaries and large river deltas in the Pacific Northwest
Essential habitat for wild salmon and other wildlife borders river deltas and estuaries in the Pacific Northwest. These estuaries also support industry, agriculture, and a large human population that’s expected to double by the year 2060, but each could suffer from more severe river floods, higher sea level, and storm surges caused by climate change.
Coastal Storm Modeling System (CoSMoS)
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions of storm-induced coastal flooding, erosion, and cliff failures over large geographic scales. CoSMoS was developed for hindcast studies, operational applications and future climate scenarios to provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety...

Recreational Birdwatching and Habitat
Thousands of visitors flock to the Billy Frank Jr. Nisqually National Wildlife Refuge every year to look for birds both rare and common. Birdwatching activities contribute to economic activity for the Nisqually area and play a role in the broader outdoor-loving culture of the Pacific Northwest. The refuge has kept detailed records of how birds are using the different habitats within the refuge...
Fisheries and Fish Habitat
The estuarine habitat of the Delta is critical to the production of salmon, which supports recreational, commercial, and subsistence fishing. The combination of shaded pools, shallow reaches, and a rich prey population provide excellent feeding grounds for juvenile fish. Fishing also holds great importance in the cultural practices of the Nisqually Tribe.
Marsh Elevation Change and Carbon Sequestration
Tidal marsh vegetation grows in a narrow elevation zone between sea level and the upland behind it. These plant communities have evolved to accumulate sediment over time and maintain their relative elevation with gradual rates of change in sea level. It is uncertain which marsh vegetation communities will be able to accumulate sediment at a rate that keeps pace with accelerated sea level rise...

USGS Benchmark Glacier Project Comprehensive Data Collection
Mountain glaciers are closely coupled to climate processes, ecosystems, and regional water resources. To enhance physical understanding of these connections, the USGS maintains a collection of glacier mass balance and climate data across the western United States and Alaska. In some cases, records of glacier mass balance extend back to the mid-1940s. These data have been incorporated from

Geodetic Data for USGS Benchmark Glaciers: Orthophotos, Digital Elevation Models, and Glacier Boundaries
Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Ice
Uranium is a radioactive element (radionuclide) that occurs naturally in rock, soil, and water – usually in low concentrations. Radionuclides are unstable atoms with excess energy and as radionuclides decay, they emit radiation. The uranium decay sequence also includes other radionuclides of concern such as radium and radon (DeSimone and others, 2014).

The geologic research and mapping in the offshore areas is foundational to understanding how to manage resources and improve public safety in subduction zone areas.
As state and national interest in offshore renewable energy development and substantial commercial and recreational fishing activities grows, managing offshore habitats becomes increasingly challenging. In response, USGS and BOEM have joined NOAA and several non-Federal partners to initiate EXpanding Pacific Research and Exploration of Submerged Systems (EXPRESS), a multiyear campaign.
One USGS scientist has sorted through the challenges, the claims, and the data to determine what the possibilities and limitations really are for EEW, and the results may surprise you.
