A sensor data logger recovered from the floor of Yellowstone Lake in the Deep Hole area in 2018 shows signs of melting due to unexpectedly high temperatures in sediments up to ~3 ft (1 m) away from an active hydrothermal vent. Image acquired by the Global Foundation for Ocean Exploration ROV Yogi on August 4, 2018.

This lava, erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone, shows classic pāhoehoe behavior. Exposed to the air, the surface of the flow chills to form a thin crust that can be stretched or broken apart, forming pieces of crust that are "subducted" back into the molten interior.

The patented “Handheld Underwater Suction Sampler” is shown here with a sample collection net attached. The sampler was initially called the "Vasco Explorer." USGS biologists from Flagstaff, Arizona, are researching food sources for fish such as the rainbow trout, which are stocked in the Glen Canyon stretch of the Colorado River.
