- USGS scientist Edward Josberger discusses research from the past 50 years to measure changes in the mass (length and thickness) of three glaciers in Alaska and Washington. These are the longest such records in North America and among the longest in the world.
- A USGS scientist holds a five-year-old stocked lake sturgeon recaptured during a survival assessment in the Genesee River, New York. Lake sturgeon were once a highly abundant fish species in the Great lakes, but populations are currently only about one percent of their historic abundance due to overfishing in the 1800s and early 1900s.
