Hyperspectral image data acquired during a tracer dye experiment on the Kootenai River, ID, September 27, 2017
To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides access to hyperspectral image acquired during the experiment and the supporting field-based measurements of reflectance and dye concentration are available through related data releases. The hyperspectral image data were acquired by Quantum Spatial Inc. (QSI) using the ITRES CASI 1500H imaging system deployed from a Cessna Caravan manned aircraft from a flying height of 1000 m above ground level. Initial geometric and radiometric data processing was performed by ITRES and yielded images with 0.5 m pixels for each of 48 spectral bands...
Vegetation and snow depth measurements in grasslands under grazing, burning, and snow fence management near Woodworth, North Dakota (2014-2016)
The application of two management strategies were tested across nine, Class III, wetland catchments located at the Woodworth Study Area (Stutsman County, ND). This field study took place during 2014 and 2015. 2014 was a pre-treatment year and snow measurements were taken in all experimental catchments in the late February 2015, before treatments were applied. Temporary electric fences were installed surrounding each wetland catchment to exclude them from grazing that took place on the management unit in 2015. All the catchments had been managed in a similar manner since purchased by USFWS in 1964. The primary management strategy of the wetland catchments from 1964–2013 was non-use with occasional prescribed burning....
Field measurements of Rhodamine dye concentration during a tracer experiment on the Kootenai River, ID, September 25-27, 2017
To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides in situ field measurements of Rhodamine WT dye concentration acquired during the experiment. A pulse consisting of 72.57 kg (160 pounds) of KEYACID™ Rhodamine WT dye that was 20% Rhodamine by weight was introduced into the Kootenai River channel from a single release point at the Kootenai Tribal Fish Hatchery over a period of 90 seconds ending at 20:10:40 PDT on 9/26/2017, which is equivalent to 04:10:40 on 9/27/2017 UTC. Information on the timing and location of the dye release is available from the KootenaiDyeReleasePoints.kmz Google...
