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.

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.

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.

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.

Graphic shows the earthquake swarm from June-July, 2019, compared to previous swarms detected in March 2019, 2017, 2016, and in 2014. The activity is likely the result of small-scale underground movements of hydrothermal fluids or gas — a sign that Mount St. Helens remains an active volcano.
