North-to-south rupture simulations at the intersection of the South San Andreas Fault and a normal fault
linkNorth-to-south (N2S) rupture simulations with oblique (−45°; panels a–d) and left-lateral (0°; panels e–h) normal fault (NF) pre-stress. In the left column (panels a, b, e, and f), the San Andreas (SSAF) ends at the intersection with the NF, while in the right column (panels c, d, g, and h), the San Andreas (SSAF-EXT) “extends” south of the SSAF-NF intersection.

Example of calibration and validation of CoSMoS-COAST using historical satellite-derived shoreline data
linkAn example of calibration and validation of CoSMoS-COAST using historical satellite-derived shoreline data. The figure shows the extent of the CoSMoS-COAST U.S. South Atlantic Coast model transects (panel A—in green) with a zoomed in section of Cape Hatteras, North Carolina (panel B), which shows a close-up of the 50 m transect spacing (green lines).

Characterizing organic carbon at Escanaba Trough
The global ocean is a significant carbon sink, absorbing about a third of all atmospheric carbon dioxide (CO2) emissions (Gruber et al., 2019).

Shoreline Seasonality of California's Beaches
Most of the world’s beaches have regular cycles of erosion and recovery, but new USGS research is showing that these cycles may be considerably different from common perceptions.

Hybrid coral reef restoration: A cost-effective, nature-based solution to protect people and property (AD)
linkCoral reef restoration can protect hundreds of millions of dollars of coastal property and business activity annually from storm-driven flooding.
It can protect thousands of people, especially children, the elderly, minorities, and those below the poverty line. Thus, coral reef restoration is a mechanism to provide environmental equity.

Eyes on Earth Episode 120 – Mapping the California Coastline
In this episode of Eyes on Earth, we begin a series on Landsat’s usefulness in coastal studies. First, we talk with Sean Vitousek, a USGS research oceanographer, about changes to beaches in California and how he is using Landsat and other data to create models that can predict how the coastline may change in the future because of sea level rise and coastal erosion.

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.
