Malheur Lake is a shallow, freshwater lake in southeastern Oregon. This data release includes phytoplankton data from three sites located in Malheur Lake collected from 8/8/2018 to 8/11/2020. For each sample collected, the phytoplankton were reported to the lowest taxonomic unit. Phytoplankton biovolume, algal cell concentration, and algal biomass concentration are included. All phytoplankton data were generated by PhycoTech, Inc. The dataset includes two comma-separated values (.csv) files and metadata. The first CSV file includes all of the taxonomic, biovolume, and density information. The second CSV file includes the 111 unique taxa identified.

An extreme flood in 2016 caused widespread culvert blockages and road failures across northern Wisconsin, including extensive damage along steep tributaries and ravines in the Marengo River watershed. Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss of wetland storage, and valley-side mass wasting. In 2020, a pilot study was begun to map and classify ephemeral and perennial streams and wetlands in terms of their susceptibility to fluvial erosion hazards. This study combines rapid geomorphic field assessments of river corridor erosion and coupled sediment and debris delivery with...

The U.S. Geological Survey (USGS) Data Release provides phytoplankton data from eight sites located in Upper Klamath Lake, OR from 6/28/2010 to 9/19/2018. Phytoplankton data are reported to the lowest possible taxonomic level and biovolume, biomass, and density are reported.

Real-time, high frequency (1-second sample interval), georeferenced water quality data was collected in Utah Lake, Utah. Utah Lake is located approximately 45 miles south of Salt Lake City, Utah, and approximately 5 miles west of Provo, Utah. Data was collected on 8/10/16 over an approximate 6.5-hour period (8:00 – 14:30 h PST) while underway. Sample water was continuously pumped through a pickup tube mounted at the stern of the vessel. Sample was pre-filtered using a 178 um in-line strainer, passed through a de-bubbler, and diverted through a 0.2 micron filter to various water quality instrumentation. Data was handled by a Campbell Scientific CR-6 data logger and recorded continuously to a Microsoft Excel file....
