| Survey Equipment | Survey Info | Data Type(s) | Data Collected |
|---|---|---|---|
| Trimble R7 GPS (AS) | --- | Benchmarks Navigation Profiles Transects | |
| Waverunners | --- | Navigation Single Beam | Nearshore bathymetry data collected from kayak (This part of the data release presents bathymetry data from the Elwha River delta collected in July 2018 (USGS Field Activity Number 2018-648-FA) using a kayak. The kayak was equipped with a single-beam echosounder and a survey-grade global navigation satellite system (GNSS) receiver.) Nearshore bathymetry data collected from personal watercraft (This portion of the USGS data release presents bathymetric data collected during surveys performed on the Elwha River delta, Washington in 2018 (USGS Field Activity Number 2018-648-FA). Bathymetric data were collected using personal watercraft (PWCs) equipped with single-beam sonar systems and global navigation satellite system (GNSS) receivers.) |
| Ponar grab sampler | --- | Biology Chemistry Geology | Surface-sediment grain-size distributions (This portion of the data release presents sediment grain-size data from samples collected on the Elwha River delta, Washington, in July 2018 (USGS Field Activity 2018-648-FA). Surface sediment was collected from 39 locations using a small ponar, or 'grab', sampler from the R/V Frontier in water depths between about 1 and 17 m around the delta. An additional 35 samples were collected by hand at low tide.) |
