Mushroom Pool, in the Lower Geyser Basin of Yellowstone National Park, as it looked in June 23, 1967. The sample that would be the source of Thermus aquaticus strain YT-1 came from this hot spring. Pictured is Thomas Brock standing near the edge of the pool. Image from the self-published "A Scientist in Yellowstone National Park" (Brock, 2017).

This timelapse sequence shows the water pond in Halema‘uma‘u Crater, at Kīlauea's summit, between November 1, 2019, and March 26, 2020. Over this time the water level rose approximately 14 meters (46 feet), equivalent to 67 cm (about 2 feet) per week. The timelapse shows one image per day (with a few cloudy images removed), and is looped several times.

The USGS St. Petersburg Coastal and Marine Science Center conducted outreach at the Localtopia Event held in February 2020. Staff demonstrated a simulation of how storms can impact sandy coastlines through processes such as erosion.

Scanning electron microprobe images show the complexity of tiny Icelandic ash grains (150 micron, or 0.006 inch). Image (a) shows a dense and blocky grain, and (b) shows a foamy grain. Photos by J. Schmith.

Answer: a GPS capable of accurately measuring elevations to within 10 cm (~4 in). In the summer of 2019, USGS organized a Light Detection and Ranging (LiDAR) survey of the Kīlauea summit and East Rift Zone, including both the Pu‘u ‘Ō‘ō and 2018 lower Puna lava flows.

The SQUID-5, or a Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with 5 cameras is a towed surface vehicle with an onboard Global Navigation Satellite System (GNSS) and 5 downward-looking cameras with overlapping views of the seafloor.

Question: what's that in the shrubs?

A CTD-rosette is a commonly used instrument that measures conductivity (that can inform scientists about salinity), temperature, and depth (CTD). As the instrument is lowered into the water--sometimes down to great depths--the cylinders around will open at various depths to collect water samples at discrete locations throughout the water column.
