Metals and minerals are vital components of medical devices that allow millions of people to enjoy healthy lifestyles. Devices implanted into the human body can replace, support, or enhance an existing body part. Other devices can diagnose, monitor, or treat clinical conditions, both saving lives and improving people’s quality of life.

 Winter temperature extremes control the distributions of subtropical fishes. Common snook (Centropomus undecimalis), aggregate at a spring in northern Florida during winter. Snook are warm saltwater game fish, common in Florida, that have been moving further northward as extreme cold spells become less frequent and less intense.

Modern equipment currently in use at the South Fork of the Ogden River streamgage, to include; an electronic data logger, pressure transducer and GOES radio. This streamgage has been monitoring water levels and flow since March 21, 1921, making it one of 25 centennial gauges in Utah. The equipment used to collect data has changed significantly over the pas

The 26th annual Mineral Commodity Summaries report from the U.S. Geological Survey National Minerals Information Center is the earliest comprehensive source of 2020 mineral production data for the world.

The United States continues to rely on foreign sources for some raw and processed mineral materials, including some critical minerals. This map shows the countries that supply mineral commodities for which the United States was more than 50% net import reliant in 2020.
