Biomass accrual and trace-element concentrations in water and periphytic algae at select locations in the Clark Fork and Blackfoot Rivers, Montana, 2015.

The U.S. Geological Survey monitored algal biomass accrual and concentrations of metals and other trace elements in stream water and periphytic algae at 3-4 day intervals over a 2-week period at 3 locations within the upper and middle portions of the mining-impacted Clark Fork River, Montana, and at one location on the relatively unimpacted Blackfoot River tributary.

Geochemistry of Water Sources in the Wolverine Glacier Watershed, Alaska in 2016 and 2017

Glaciers are critical sources of water and solutes to downstream riverine and marine ecosystems. Samples were collected from surface streams, groundwater, rain, snow, and ice in the Wolverine Glacier basin and analyzed for a broad suite of geochemical constituents including common field parameters, major ions, stable isotopes of water, nutrients, metals, and dissolved organic carbon.
