Testing a USGS patented device (DSIM) and measuring it's performance with a new analytical upgrade recently designed and installed. The DSIM allows for gas samples to be put into a spectrometer and measured in a closed loop, which increased the data signal fidelity, repeatability, and amount an analyte used.
Multimedia
The Coastal and Marine Hazards and Resources Program shares a wide range of resources to help explain and illustrate scientific concepts, our scientific activities, expertise, technology, tools, and other educational resources. Through newsletters, multimedia resources, special events, and other products, you can learn more about the many ways our science supports the Nation.

Geologic model for abyssal seismoturbidite generation along the Cascadia Subduction Zone
Geologic model for abyssal seismoturbidite generation along the Cascadia Subduction ZoneGeologic model for abyssal seismoturbidite generation along the Cascadia Subduction Zone. (A) With each earthquake cycle, slope failures occur on the oversteepened limbs of thrust folds in the accretionary wedge, resulting in proximal MTDs and turbidity flows that spread out across the abyssal plain.

Enlargements of 1-m AUV bathymetry overlain on 30-m bathymetry grid for the study area along the Cascadia Subduction Zone
Enlargements of 1-m AUV bathymetry overlain on 30-m bathymetry grid for the study area along the Cascadia Subduction ZoneEnlargements of 1-m AUV bathymetry overlain on 30-m bathymetry grid for the study area along the Cascadia Subduction Zone. (A) The AUV bathymetry data reveal a 10m high failure scarp that extends for 4km along the seaward face of the frontal thrust fold. Secondary reverse faults observed in the chirp subbottom data are expressed at the seafloor with ~3m offsets.

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.
