A Pacific Northwest icon, Puget Sound is the second-largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to growth in human population and urbanization. This growth has played a role in degrading the Sound, including declines in fish and wildlife populations, water-quality issues, and changes in coastal habitats. Natural resource managers look to the USGS as a critical science resource needed to solve problems in this important ecosystem.
The deterioration of the Puget Sound nearshore is of special concern — the area extending from the top of shoreline bluffs to a depth offshore where sunlight does not reach the bottom, and upstream in estuaries to the head of tidal influence. It includes bluffs, beaches, mudflats, kelp and eelgrass beds, salt marshes, gravel spits, and estuaries. Because the nearshore is one of the most productive parts of the Sound, improved understanding of it is vital to restoration and preservation of the entire Sound.
To develop a restoration program, Federal, State, Tribal, and local governments, non-governmental organizations, universities, and private industry joined in 2001 to create the Puget Sound Nearshore Ecosystem Restoration Project (PSNERP). In December 2005, protection and restoration of Puget Sound was expanded in scope with the creation of the Puget Sound Partnership. As a task force within the Governor of Washington's Puget Sound Initiative, the Puget Sound Partnership's goal is to develop recommendations to restore the Sound by 2020.
The overall scientific goal of the CHIPS project is to provide scientific support for ecosystem recovery activities in Puget Sound. Through its diverse studies, the CHIPS project strives to demonstrate a structure and process for conducting interdisciplinary ecosystem science.

Time-series data of velocity, pressure, turbidity, conductivity, and temperature were collected near the mouth of the Elwha River, Washington, USA, from December 2010 through October 2014, for the Department of Interiors Elwha River Restoration project. As part of this project, the U.S. Geological Survey studied the effects of renewed sediment supplies on the coastal ecosystems before...
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington
Two dams on the Elwha River, Washington State, USA trapped over 20 million cubic meters of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a...
Oceanographic measurements and hydrodynamic modeling of the mouth of the Columbia River, Oregon and Washington, 2013
During May and June of 2013, the U.S. Geological Survey in collaboration with Naval Post-Graduate School, the University of Miami, and Deltares USA, participated in the Office of Naval Research-funded River and Inlets Dynamics (RIVET II) experiment to investigate the hydrodynamics of the mouth of the Columbia River (MCR). The field experiment consisted of the collection of continuous...

Polychlorinated biphenyls (PCBs) in the Pacific sand lance, Puget Sound, Washington
Forage fish are small, abundant, schooling planktivores that form a critical link in marine food webs by transferring energy from plankton up to birds, fishes, and marine mammals. Forage fishes in Puget Sound include the iconic Pacific herring as well as lesser known species such as surf smelt and the Pacific sand lance. There are significant knowledge gaps regarding the basic life...

Sources, timing, and fate of sediment and contaminants in the nearshore: insights from geochemistry
Rivers in Cascade watersheds carry sediment with a volcanic composition that is distinct from the plutonic composition of the Puget lowlands. Compositional properties (signatures) allow discrimination of river-sourced Cascade from lowland sediment, and inferences about transport pathways. Surface sediment on land contains atmospheric radionuclides whose known decay rates define monthly...

Contaminant baselines and sediment provenance along the Puget Sound Energy Transport Corridor, 2015
The transport of coal and oil can result in contaminated soil, water, and organisms from unintended releases. Trains carrying coal and crude oil regularly pass through Puget Sound, Washington, and an increase in the number of coal and oil trains is expected in the future. This study characterized levels of potentially toxic contaminants in sediment in September 2015: arsenic, metals, and...

Conceptualizing ecological responses to dam removal: If you remove it, what's to come?
One of the desired outcomes of dam decommissioning and removal is the recovery of aquatic and riparian ecosystems. To investigate this common objective, we synthesized information from empirical studies and ecological theory into conceptual models that depict key physical and biological links driving ecological responses to removing dams. We define models for three distinct spatial...

Geomorphic evolution of a gravel‐bed river under sediment‐starved vs. sediment‐rich conditions: River response to the world's largest dam removal
Understanding river response to sediment pulses is a fundamental problem in geomorphic process studies, with myriad implications for river management. However, because large sediment pulses are rare and usually unanticipated, they are seldom studied at field scale. We examine fluvial response to a massive (~20 Mt) sediment pulse released by the largest dam removal globally, on the Elwha...

Do we know how much fluvial sediment reaches the sea? Decreased river monitoring of U.S. coastal rivers
Given the present and future changing climate and human changes to land use and river control, river sediment fluxes to coastal systems are changing and will continue to change in the future. To delineate these changes and their effects, it is increasingly important to document the fluxes of river-borne sediment discharged to the sea. Unfortunately, broad-scale river sediment monitoring...

Juvenile Chinook salmon and forage fish use of eelgrass habitats in a diked and channelized Puget Sound River Delta
Eelgrass Zostera marina can form extensive meadows on Puget Sound river deltas. The extent to which these meadows provide critical rearing habitat for local estuarine fishes, especially out‐migrating juvenile salmon, is not well understood. Further, delta eelgrass has been impacted by diking and river channelization with unknown consequences for fish. We sampled fish in the Skagit River...
