Petrographic, SEM, and STEM images of bladed marcasite and bladed pyrrhotite
Petrographic, SEM, and STEM images of bladed marcasite and bladed pyrrhotitePetrographic (A, D) SEM (B, E) and STEM (C, F) images of bladed marcasite (A, B,C) and bladed pyrrhotite (D,E,F). The petrographic images are reflected light under plane polarization. The brassy minerals in D are isocubanite being replaced by chalcopyrite.

Lake Chelan Mapping and Sediment Coring
In 2023, scientists with the USGS Pacific Coastal and Marine Science Center completed a 3-week field operation in Lake Chelan, Washington, the third deepest lake in the conterminous United States, to acquire sediment cores, high-resolution bathymetry data, and chirp sub-bottom profiles.

Hawai'i Abyssal Nodules Expedition (AD)
In Fall 2025 the Hawaiʻi Abyssal Nodules and Associated Ecosystems Expedition, led by USGS scientists, will investigate the geology, minerals, and environmental setting of the deep seabed offshore Moku o Keawe (Hawaiʻi Island) in the U.S. Exclusive Economic Zone. This work is part of ongoing collaborative efforts with BOEM and NOAA.

Nuvuk video camera 2 dark image
Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
