Drought in the Colorado River Basin - Insights Using Open Data

Since 2000, the Colorado River Basin has been experiencing a historic, extended drought that has impacted regional water supply and other resources, such as hydropower, recreation, and ecologic services. This visualization is part of a multi-agency effort to showcase the usefulness of open data by exploring the current 16-year drought and its effects on the Colorado River Basin.

Pore water chemistry of wetlands in Interior and Southcentral Alaska, 2015 and 2016

The pore water of eight wetlands in Interior and Southcentral Alaska were collected in 2015 (17 July – 22 July) and 2016 (12 July – 16 July). Wetlands were selected to span a range in trophic status (e.g., from bog to fen). Using ultraclean trace metal clean protocols, pore waters were sampled from shallow (10‑15 cm) and deep (20-35 cm) depths below

Dissolved organic carbon concentration and dissolved organic matter characteristics in surface water samples from the U.S. Geological Survey National Water Quality Network rivers, 2008 to 2018

The sampling of 41 hydrologically diverse rivers that are monitored through the National Water Quality Network (NWQN) by the U.S. Geological Survey (USGS) took place during the water years of 2008 through 2018. Water samples were collected and filtered in the field (unless otherwise noted) using 0.45 micrometer pre-rinsed capsule filters (Versapor membrane), silicon tubing, an

Near-surface electromagnetic imaging (EMI) data collected along the Santuit River, Mashpee, MA.

Hand-carried frequency domain electromagnetic imaging (EMI) data were collected along the Sanuit River to indicate changes in streambed water quality and/or near surface sediments. These data are to be used in conjunction with fiber-optic distributed temperature sensing (FO-DTS) and ground penetrating radar (GPR) data. The combined dataset represents point in time mapping of prefe
