What do glaciers and pigs have in common?

They both have snouts.  Glaciers periodically retreat or advance, depending upon their mass balance. This is their snow accumulation balanced against evaporation and melting (ablation)​. Glacial retreat and advance refer only to the position of the terminus, or snout, of the glacier.  To better understand the modern glacier environment, take a look at the photo Glossary of Glacier Terminology.

Is that Santa and his reindeer?

It might just be the Landsat 8 satellite streaking northward in the nighttime sky. The Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) are instruments onboard the Landsat 8 satellite, which was launched in February of 2013. The satellite collects images of the Earth with a 16-day repeat cycle, referenced to the Worldwide Reference System-2.  (Landsat 8 doesn't use reindeer.)

If you hurry can you run away from a storm?

Tropical storms are events we can see coming, giving residents of coastal or low-lying areas time to get to higher ground. Tropical storms can bring high water, dangerous waves, and currents that can move large amounts of sand, destroying buildings and infrastructure, reshaping our coastline.

The USGS studies coastal storms and creates information to help responders and decision-makers minimize damage in the future.

Will USGS send me a Turkey dinner?

No, but the USGS  monitors the Turkey River, Turkey Creek, and other sites, and can send you real-time water data (typically recorded at 15-60 minute intervals and transmitted within 4 hours). You may subscribe to WaterAlert and receive data via email or text. If you only are wondering “How high is the river today?” you can send a text or email to WaterNow.

Do scientists need to kill bats?

Not any longer.  The only way to confirm white-nose syndrome (WNS) used to be to euthanize a bat and send it back to a laboratory for testing, but UV light can now help diagnose this disease in bats.  When UV light is directed at the wings of infected bats, it produces a distinctive orange-yellow fluorescence, a good indication of bats that are infected.  Now scientists only take a small biopsy for testing rather than sacrifice a bat.
