A close-up image of native sulfur crystals that formed within fumaroles at the Sulphur Banks in Hawai‘i Volcanoes National Park. In addition to sulfur species and other gases, volcanoes emit water vapor. Here, some of the vapor has condensed to liquid water and formed droplets visible on the sulfur crystals. USGS photo by P. Nadeau.

Different sulfur gases, including sulfur dioxide (SO₂) and hydrogen sulfide (H₂S), can react with each other to deposit crystals of pure native sulfur at sites of degassing called fumaroles. The crystals picture here formed within a Sulphur Banks area fumarole in Hawai‘i Volcanoes National Park. USGS photo by T. Elias.

As part of routine monitoring efforts, HVO gas scientists collected helium samples from fumaroles in the Sulphur Banks, or Ha‘akulamanu, area of Hawai‘i Volcanoes National Park on September 30, 2020. Helium can pass through the glass of typical gas sampling bottles, so copper tubing is necessary for the specialized sample.

The bathymetric mapping is part of a streambed scour study conducted in cooperation with the Alaska Department of Transportation and Public Facilities.

Springs discharging from the artesian aquifer are commonly supersaturated with minerals. In this photo at Iron Spring a small mound of iron hydroxides is forming below where the spring outflows to Fountain Creek.

Marine engineering technician Pete Dal Ferro sets up a newly acquired, portable, single-beam echo sounder on the San Lorenzo River in Santa Cruz, California. The new device, called CEESCOPE, collects bathymetric (depth) data and also records features of the subsurface.
