Description:

Abstract:

RBRduo pressure and temperature sensors (early 2015 generation), mounted on aluminum frames, were moored in shallow (< 6 m) water depths in Skagit Bay 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.

Purpose:

Wave observations were collected as part of the USGS Coastal Climate Impacts Project and development of the Puget Sound Coastal Storm Modeling System (PS-COSMOS) for Puget Sound and the Salish Sea. The wave data help support the validation of the PS-CoSMoS regional wave model for forecasting future extreme high-water levels and flood risk with projected sea-level rise and to characterize the present-day wave climate.

Process_Description:

Instrumented frames were deployed by hand on December 11, 2017 at 3 locations (S1, S2, S3) from a 17-foot sea Ark skiff and recovered on February 9, 2018. Aluminum frames with a 1-m footprint were equipped with RBR's RBRduo pressure and temperature sensor (early 2015 generation). Mushroom and fluke anchors were attached to frames with chain. Twelve-inch surface floats were attached to anchors for recovery and were not expected to impact instrument recording. Pressure and temperature were recorded continuously at 2Hz during the deployment. Sensor height above bottom was estimated to be 20cm after some settling of the frame in sediment. During deployment and recovery depth was sampled with a handheld sonar and position was recorded with a handheld GPS. The instrument package and mooring system were light enough to deployed and recovered by hand. On February 9, 2018 all instruments were successfully recovered.

Process_Description:

After recovery, the manufacturers' software, Ruskin v2.4, was used to download the data. Surface gravity wave properties were estimated from pressure fluctuations following methods developed by Jones and Monismith (2007). Wave properties are estimated under two assumptions, that linear wave theory is valid, and that current speeds are small compared to wave phase velocities. These assumptions may be violated in shallow water depths during large wave events, e.g. wave breaking, and during strong ebb or flood tides. Python 3.0 operating within Windows 10 was used to process the data and scripts are available in the public repository, https://github.com/dnowacki-usgs/stglib.
