Staff from the USGS Pacific Coastal and Marine Science Center Marine Facility engineered a Free Ascent Tripod (FAT) for deployment in deep-sea environments along the Cascadia Subduction Zone.

Monitoring coastal changes is important for the millions of people that live along coasts in the United States, particularly as climate change hastens coastal erosion by raising sea levels and fueling powerful storms.

The Sacramento and San Joaquin Rivers deliver half the amount of sediment they did 50 years ago to San Francisco Bay. Just as sea-level rise is accelerating, the demand for sediment is growing.

Our Nation’s coastlines are almost 100,000 miles long. These extensive coastal areas stretch from Maine’s Atlantic shores in the northeast, south along the shores of the Gulf of Mexico and insular areas in the Caribbean.

To better understand the geophysical characteristics and seismic history of the Cascadia Subduction Zone, USGS researchers conduct fieldwork at sea to collect evidence of turbidity currents from underwater landslides likely caused by earthquake shaking.

A virtual “flight” over seafloor features in Southern California as if the water has been drained away. The flight travels around the features Footprint and Piggy Bank, just south of the northern Channel Islands in southern California.

The familiar saying “good things come in small packages” holds especially true for deep-sea biological communities at hydrothermal vents, including those at Escanaba Trough, a seafloor spreading center located almost 200 miles off the northern California coast.

Coral reefs are important for supporting biodiversity, fisheries, tourism, and coastal protection, but are in decline worldwide, primarily due to extreme heat waves and subsequent coral bleaching, in addition to other stressors.

Coral reefs act like submerged breakwaters by breaking waves and dissipating their energy offshore before they flood coastal properties and communities. This is an enormously valuable function: In 2017, Hurricanes Harvey, Irma and Maria alone caused over $265 billion in damage across the nation.

This talk was presented at the 15th International Coral Reefs Symposium, 03-08 July 2022 (Hybrid event), under Theme 12, Conservation and Management, Session 12E:  How can scientists and managers identify optimum catchment management actions to improve downstream condition for reefs and people?

Expanding Pacific Research and Exploration of Submerged Systems (EXPRESS) is an inter-agency federal and nonfederal collaborative research effort aimed at gathering new data of the deep ocean, continental shelf and slope offshore of California, Oregon and Washington.

Between January 14-15, 2022, volcanic eruptions destroyed much of Hunga Tonga-Hunga Ha'apai, an uninhabited island in the Tonga archipelago in the southern Pacific Ocean. A plume of ash rising 36 miles into the atmosphere blanketed the neighboring Tongan islands.

Seafloor features such as sulfide mounds and chimneys are prominent evidence of hydrothermal activity. These features, whether active or dormant, are just the tip of the iceberg, so to speak; much of the “plumbing” of hydrothermal systems exists beneath the seafloor surface.
