Tree-ring sample from an avalanche path
This tree-ring sample from an avalanche path captures 256 years of data between the years 1777 and 2013. The scars in 1818 and 1974 are examples of mechanical damage caused by an avalanche. The pith is the center of the tree.

Jamaica Bay UVVR
Within the busy boroughs of Brooklyn and Queens, New York City, is Jamaica Bay—a complex urban ecosystem almost the size of Manhattan that consists of salt marsh islands, various waterways, meadowlands and two freshwater ponds.

Annual Mauna Loa GPS Survey—2021
GPS campaign survey stations high on the flanks of Mauna Loa offer expansive views of neighboring volcanoes. From this station located west of Mauna Loa summit, Hualālai volcano is visible. Most Mauna Loa GPS campaign survey sites have been occupied every year since 1996, whereas less active volcanoes Hualālai and Haleakalā are surveyed every 3–5 years.

Everglades National Park UVVR
Everglades National Park in South Florida is the largest subtropical wetland ecosystem in North America, consisting of about 1.5 million acres of mangrove forests and other coastal wetlands. Mangroves are salt-tolerant trees that thrive amidst the harsh growing conditions of the coast.

Sunset on the R/V Sproul
Looking across the back deck/stern of the R/V Robert Gordon Sproul. The wire going through the block in the A-frame leads to the CHIRP sonar fish towed in the water. Oil platforms are shown in the distance.

Halema‘uma‘u lava lake, Kīlauea summit eruption—April 30, 2021
Halema‘uma‘u lava lake, Kīlauea summit eruption—April 30, 2021On Friday, April 30, lava continued to erupt from the west vent in Halema‘uma‘u at the summit of Kīlauea Volcano. Active surface lava (center of the photo) was limited to the center of the previously active lake surface, where the north (right) and south (left) sides have cooled and crusted over (appearing darker in the image). This photo was taken around 2 p.m.
