Wave observations from nearshore bottom-mounted pressure sensors in Skagit and Bellingham Bays, Washington, USA from Dec 2017 to Feb 2018 RBRduo pressure and temperature sensors, mounted on aluminum frames, were moored in shallow (< 6 m) water depths in Skagit and Bellingham Bays, Washington, USA, from December 2017 to February 2018, to capture wave heights and periods. Continuous pressure fluctuations are transformed into surface-wave observations of wave heights, periods, and frequency spectra at 30-minute intervals.

Toxicity testing was conducted from fall 2013 through summer 2014 with the amphipod, Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea. Short-term toxicity endpoints (10-28 d) included survival, weight, and biomass of all test organisms. Long-term tests with amphipods (42 d) and midges (about 50 d) included reproduction endpoint. These data are intended to be used to characterize concentration-response relationships between metals concentrations...

Measurements were made on March 27, 2014, April 16, 2014, May 18, 2014, and May 29, 2014 at breach PSB1, and on May 29, 2014 at breach PSB2. These data were collected using a boat-mounted Teledyne RDI RiverRay 600 kHz acoustic Doppler current profiler (ADCP) or a Teledyne RDI StreamPro 2000 kHz ADCP, depending on date. ADCP transect data were collected and initially reviewed using WinRiver II software and reprocessing and final review was completed with QRev software.

The goal of the U.S. Geological Survey’s component of the research was to evaluate the various hydrodynamic and sediment transport processes in the Columbia River estuary entrance using a combination of field observations coupled with Delft3D model simulations. The MCR is a dynamic estuary inlet with large waves, large tidal currents, and a significant river discharge, resulting in strong estuarine circulation. The field component of the study consisted of an intensive in-situ experiment including bottom-mounted...
