Field Activity K104PS

Identifier K104PS
Alternate names K-1-04-PS
Purpose Submetrix swath sonar work, ship-towed video, ground penetrating radar, coring, and sediment and eelgrass grab samples.
Description United States Geological Survey, Menlo Park, California. Chief Scientist: Eric Grossman. Geological and Geophysical data (bathymetry, underwatertelevision, groundpenetratingradar, vibratingcore, VanVeengrab, imagery) of field activity K-1-04-PS in Skagit River Delta, Puget Sound, WA from 03/06/2004 to 03/07/2004
Location WA
Summary Bathymetry data along delta front shows evidence that sediment is accumulating and burying eelgrass habitats. Ship tow video reveals that extensive areas previously colonized by eelgrass (in aerial photographs of 1990 and 2000) are now covered by fine sand and silt. GPR data image the distribution and morphology of tidal and distributary channels now buried beneath agricultural land. Sediments from cores show 1-3 m of recent fine marsh sediments and peats overlying more than 3-7 m of medium to coarse sands interpreted as past tide flats. Calibrated 14C ages of wood and shells more than 10 m below the marsh surface across more than 1 km2 area of the Southern Skagit Delta range 150 to 400 yr BP signifying rapid rates of vertical accumulation (2.3 to 6.3 cm/yr) over the historical period. Preliminary analyses of surface sediments show that eelgrass biomarkers may be preserved in the recent geological record and may serve as a proxy for past eelgrass abundance.

High-resolution bathymetry data collected in 2004 in Skagit Bay, Washington sidescansonar These metadata describe the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) 2004 bathymetry data collected in Skagit Bay Washington that is provided as a 1-m resolution TIFF image, as well as a 1-m resolution shaded-relief TIFF image. In 2004, 2005, 2007, and 2010 the USGS, PCMSC collected bathymetry and acoustic backscatter data in Skagit Bay, Washington using an interferometric bathymetric sidescan-sonar system mounded to the USGS R/V Parke Snavely and the USGS R/V Karluk. The research was conducted in coordination with the Swinomish Indian Tribal Community, Skagit River System Cooperative, Skagit Watershed Council, Puget Sound Nearshore Ecosystem Restoration Project, and U.S. Army Corps of Engineers to characterize estuarine habitats and processes, including the sediment budget of the Skagit River and the influence of river-delta channelization on sediment transport. Information quantifying the distribution of habitats and extent that sediment transport influences habitats and the morphology of the delta is useful for planning for salmon recovery, agricultural resilience, flood risk protection, and coastal change associated with sea-level rise.
