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.

Multi-Sensor Core Logger Laboratory

The MSCL at the USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California automatically measures P-wave velocity, magnetic susceptibility, electrical resistivity, and gamma density at intervals from 1 millimeter to 1 centimeter along cores up to 1.5 meters long. The device can also automatically line-scan photograph cores that have been split, at a resolution of 10...

Sediment Lab Suite and Carbon Analysis Lab

At our Science Center, we have a suite of laboratories that we affectionately call the "sed lab." The sed lab really consists of 5 labs, arranged next to each other to allow our lab technicians to easily move back and forth between them while processing sediment samples: Sediment Preparation Lab, Fine Particle Analysis Lab, Settling Tubes Lab, Fume Hood Lab, and Carbon Analysis Lab.

Core Preparation and Analysis Laboratory and Sample Repositories

We process and analyze sediment cores collected from coastal, fluvial, estuarine, lacustrine, and marine environments. We have a Geotek core splitter, shrink wrap system, and a wide assortment of sampling tools and balances for core sample preparation and analysis. We store the cores, along with other sediment samples, in a large, walk-in refrigerated room that features library-style rolling...

Core X-Ray: 3-D CT Core Imaging Laboratory

The Geotek RXCT, a "rotating x-ray computed tomography" system, creates ultra high-resolution imagery of sediment cores. The system resides at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California. It requires the operator to take specialized training and hold X-ray radiation and safety certifications.

USGS science supporting the Elwha River Restoration Project

 

The Elwha River Restoration Project has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington. Coordinated by the National Park Service, restoration of the Elwha River included the removal of two large dams that had blocked salmon and sediment passage for almost 100 years. The largest dam removal in U.S. history began in...

COAWST: A Coupled-Ocean-Atmosphere-Wave-Sediment Transport Modeling System

Understanding the processes responsible for coastal change is important for managing both our natural and economic coastal resources. Storms are one of the primary driving forces causing coastal change from a coupling of wave- and wind-driven flows. To better understand storm impacts and their effects on our coastlines, there is an international need to better predict storm paths and...

Samples Repository

Since 2002, the Woods Hole Coastal and Marine Science Center’s Samples Repository (WHCMSC) has been supporting research by providing secure storage for geological, biological, and geochemical samples; maintaining organization and an active inventory of these sample collections; as well as by providing access to these collections for study and reuse.

Estuarine and MaRsh Geology Research Project

The goal of the Estuarine and MaRsh Geology (EMRG) Research Project is to study how and where short- and long-term marsh and estuarine coastal processes interact, how they influence coastal accretion or erosion, and how they pre-condition a marsh’s resiliency to storms, sea-level change, and human alterations along the northern Gulf of Mexico (Grand Bay and Point aux Chenes, Mississippi and St...
