| Survey Equipment | Survey Info | Data Type(s) | Data Collected |
|---|---|---|---|
| ADCP - 600 kHz | --- | Current Wave | Vessel-mounted acoustic Doppler current profiler (ADCP) data (This dataset contains water velocity data derived from spatial surveys performed with a vessel-mounted acoustic Doppler current profiler at four sites (SKM, SLG, LDB, WLW) in the lower Columbia River, Washington and Oregon, in 2021. The data are provided in netCDF (.nc) format and compressed into .zip archives for each site.) |
| Eyeball | --- | Photo | In situ seafloor images (In situ seafloor images were acquired at four sites (SKM, SLG, LDB, WLW) in the lower Columbia River, Washington and Oregon, with an underwater camera system between June 5 and June 8, 2021. ) Surface sediment grain size distributions derived from in situ seafloor images (This dataset contains surface sediment grain size distributions derived from automated image processing of in situ seafloor images obtained with an underwater camera system at four sites (SKM, SLG, LDB, WLW) in the lower Columbia River, Washington and Oregon, in 2021.) Surface sediment grain size distributions derived from manual point counts of in situ seafloor images (This dataset contains surface sediment grain size distributions derived from manual point counts of in situ seafloor images obtained with an underwater camera system.) Surface sediment grain diameter measurements from point counts of in situ seafloor images (This dataset contains surface sediment grain diameter measurements from in situ seafloor images collected in the lower Columbia River, Washington and Oregon, in 2021.) |
| Ponar grab sampler | --- | Biology Chemistry Geology | |
| SWATH plus-M | --- | Interferometric | Bathymetry and seafloor acoustic backscatter of mobile subaqueous sand dunes (Bathymetry and seafloor acoustic backscatter data were collected at four sites (SKM, SLG, LDB, WLW) using a SWATHPlus interferometric sonar (234 kHz) pole mounted to the R/V Parke Snavely.) |
