The Arctic Ocean is undergoing dramatic sea ice reduction and warming conditions. The researchers of this project use microfossils from sediment cores taken in the Beaufort Sea to rebuild the climate patterns, sea ice and circulation, and ecosystems from the past 2000 years. Three interactive data visualizations help tell this story.

Glaciers and ice caps around the world are melting. Deposition of dark aerosols from fire on ice can increase glacier melting. The researchers of this project use ice cores from the Juneau Icefield to show how wildfires in the region are affecting the icefield. Three interactive data visualizations help tell this story.

Intro

Hawaiian coastal wetlands provide important habitat for endangered waterbirds and socio-cultural resources for Native Hawaiians. Currently, they are degraded by development, sedimentation, and invasive species and, thus, require restoration. Site prioritization represents both an actionable plan for coastal wetland restoration and an alternative protocol for restoration decision-making.

The USGS Ecosystems Mission Area provides science to understand wildlife diseases, including avian influenza (AI). Avian influenza viruses occur naturally in wild birds such as ducks, geese, swans, and gulls. These viruses generally do not cause illness in wild birds but they can be highly pathogenic and cause illness and death in poultry and wildlife. Learn more with this geonarrative.

USGS paleoclimate scientists use biological, chemical, and physical materials preserved in the geologic record, called geologic proxies, to investigate past climates.

Learn how the U.S. Geological Survey (USGS) uses data and tools to facilitate the restoration and management of post-fire landscapes. This Story Map includes examples from fire sites within the Great Basin of the western U.S.

To help resource managers plan and mitigate long-term drought impacts in the Colorado River Basin, the USGS has launched a platform that brings together science, data, and mapping and analytical tools from across the basin in a central location.

Drinking-water quality and potential exposures to per- and poly-fluoroalkyl substances (PFAS) at the point-of-use (tapwater) are a rising concern in the United States (US).

Collection of Cooperative Research Units Program (USGS Ecosystems Mission Area) year in review reports and abstracts. We provide graduate education in fisheries and wildlife sciences and partner with natural resource agencies and universities on topics of mutual concern. Today, there are 42 Units in 40 States, with a national program office in Reston, Virginia.

The United States is more than just the fifty states and the District of Columbia. Five permanently inhabited territories in the Pacific Ocean and the Caribbean Sea are overseen by the U.S. and are home to more than 4 million people, many of whom are American citizens.
