The Prime Hook National Wildlife Refuge in Delaware is the site of a \$40 million tidal marsh restoration project—one of the largest restoration projects ever in the eastern U.S. With this project, the U.S.

Four close-up images of a longer sediment core (bottom). The light coloring indicates coarser sand that likely occurred from overwash flooding during a previous hurricane. This is one of a few cores collected in northwest Florida by the USGS and partners to help understand past hurricane activity in the Gulf of Mexico and northern Atlantic Ocean.

 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.

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.

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
