Bathythermograph Data, Lake Michigan, 1954

In 1954 researchers at the USGS Great Lakes Science Center conducted 11 research cruises on Lake Michigan during which 779 bathythermographs were cast to collect temperature profile data (temperature at depth). Bathythermographs of that era recorded water pressure and temperature data by mechanically etching them as a curve on a glass slide. Data was collected from the glass slide by projecting th

Nowcast - Water-Quality Conditions At Beaches And A Recreational River

The Ohio Nowcast is a system that provides near-real-time beach advisories to the public through use of quick measurements and predictive models.

Water Quality Monitor Network In Ohio

Stream water-quality characteristics provide scientists and water managers with a better understanding of the effects of natural and anthropogenic (human) activities on streams and ecosystems. The USGS operates a network of near-real-time water-quality monitoring stations that provide data for temperature, specific conductance, pH, dissolved oxygen, and turbidity of surface water.

Wisconsin Real-Time Groundwater-Level Network

The Real-Time Groundwater Level Network contains data typically recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. All real-time data are provisional and subject to revision.

Aquatic invertebrates and vegetation and water-quality of Big Stone National Wildlife Refuge, Minnesota: 2013-2014

During 2013 and 2014 aquatic invertebrates were collected and vegetation was inventoried from sample locations distributed throughout Pool 10 and West Pool of Big Stone National Wildlife Refuge. Invertebrate sampling was conducted using aquatic activity traps and by collecting organisms from submersed vegetation. Vegetation was inventoried through a combination of visual observation and collection
