Sea otter skulls being prepared for archival
Skulls were collected in Spring 2018 & 2019 from coastlines throughout Alaska. It is assumed the animals died of natural causes over the preceding winters. They were collected under Marine Mammal Permit # 067925.

GPS survey is completed annually on Mauna Loa
A high-precision Global Positioning System (GPS) survey is completed annually on Mauna Loa. This station was occupied for a period of three days to supplement the continuously operating GPS stations on the volcano. A beautiful view of Mauna Kea (in distance) could seen from this site during the GPS survey.

Testing New Drone Technology to Measure Floodwaters
Testing New Drone Technology to Measure FloodwatersA USGS crew used new drone technology to test and evaluate new technology to measure water speed from the air without touching the water. This drone footage was taken on the Missouri River at Hermann, Missouri on March 27, 2019. Scientists compared these new method results to the conventional way of taking measurements from a boat.

A 50-Year Flooding Flashback
The high-water marks set by the Big Sioux River in cities across southeastern South Dakota have threatened to overtake records set 50 years ago, when the Army Corps of Engineers led missions to document the damage through hundreds of aerial photographs.

small amounts of sulfur dioxide
Only small amounts of sulfur dioxide (SO2) and hydrogen sulfide (H2S) are currently being released from Kīlauea, but they chemically react with each other (oxidation-reduction reaction) to form the bright yellow sulfur deposits visible on the crater walls within Halema‘uma‘u.
