Water-surface elevations were recorded by submerged pressure transducers in Spring, 2015 along the upper Willamette River, Oregon, between Eugene and Corvallis. The water-surface elevations were surveyed by using a real-time kinematic global positioning system (RTK-GPS) at each pressure sensor location. These water-surface elevations were logged over a small range of discharges, from 4,600 cubic feet per second to 10,800 cubic feet per second at Harrisburg, OR. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple datasets that will be released for this...

Water surface elevations within seven Willamette River off-channel features (OCF; alcoves and side channels) were measured using submerged pressure transducers. Transducers were installed from late May through mid-October, 2016, when discharge of the Willamette River was between approximately 5,500 and 45,000 cubic feet per second at Salem, Oregon (USGS gage 14191000) and 3,500 to 17,500 cubic feet per second at Harrisburg, Oregon (USGS gage 14166000). Pressure transducer sensor depth was measured at all seven sites. For five of the sites, pressure transducer sensor depths were converted to water surface elevations by surveying the water surface at each transducer with a real-time kinematic global positioning system...

Water-surface elevation measurements were collected in Spring, 2015 along the upper Willamette River, Oregon, between Harrisburg and Corvallis. These surveys were collected over a small range of discharges, from 6,900 cubic feet per second to 8,300 cubic feet per second, using a real-time kinematic global positioning system (RTK-GPS) on a motorboat at various cross sections along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

River bathymetry and stream velocity measurements were collected in March 2015 along the upper Willamette River, Oregon, between Eugene and Corvallis. These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) and acoustic Doppler current profiler (ADCP) on a motorboat while transecting at various cross sections along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

Water-surface elevation measurements were collected in March 2015 along the upper Willamette River, Oregon, between Eugene to Corvallis. These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) on a motorboat traveling "on plane" along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

River bathymetry surveys were collected in the summer and fall of 2016 along the lower Chetco River, Oregon. These surveys were collected using a real time kinematic global positioning system (RTK-GPS) and an echo sounder mounted on a motorboat and also behind a kayak at various cross sections and longitudinal profiles along the river. These datasets were collected in support of a funded effort investigating the cause of salt water intrusion that has taken place at the water intake facility for Harbor City, Oregon. The surveys were collected at sections approximately 0.4 river miles downstream to 0.8 river miles upstream of the Harbor City water intake structure and also at the city of Brookings water intake facility,...
This project uses bottom-up modeling at a parcel scale to measure the effects of sea-level rise (SLR) on coastal ecosystems and tidal salt marshes. At selected tidal marshes, the project team will measure several parameters that will be incorporated into ArcGIS models creating comparable datasets across the Pacific coast tidal gradient with a focus on 2-4 sites in the California LCC (e.g. San Diego, San Francisco Bay Refuges). The ultimate goal is to provide science support tools for local adaptation planning from the bottom-up that may be implemented under a structured decision-making framework.Science Delivery Phase (2013): The objectives are to: (1) Disseminate site-specific baseline data and modeling results,...

These are terrestrial laser scanner datasets collected in forested areas west of Flagstaff, Arizona in 2015 and 2016. For each of the two scanners, six treatment areas were scanned, with four of them overlapping one another (Figure 1). These data are composed of individual scans referenced to one another using reflective targets, and geolocated using differentially corrected GPS and RTK locations of scan locations (Figure 3). There were overall large differences in point density among the two scanners (Figure 2).

River bathymetry measurements were collected in 2017 and 2018 along the Willamette River, Oregon, between Eugene and Newberg. These data were collected to complement a bathymetric lidar dataset collected in 2017 for the same section of river. In many deeper segments of the river channel, bathymetric lidar did not produce measurements of river bathymetry. To fill gaps in the bathymetric lidar dataset, USGS combined bathymetry data previously collected in 2015 and 2016 with newly collected survey data from 2017 and 2018. The bathymetric survey data acquired in 2017 and 2018 focused on filling gaps within the 2017 bathymetric lidar dataset. Bathymetry data were collected using a network based real time kinematic global...
