Research cruises taken on the JOIDES Resolution are often interdisciplinary and collaborative across many universities, scientific agencies, and other research institutions.

Mounds of sand cleared from the roadway stand high on both sides of a road near the beach in Pensacola Beach, Florida, in October 2004 after Hurricane Ivan.

This coral garden was discovered in the Stetson-Miami Deepwater HAPC during the 2019 Southeastern U.S. Deep-sea Exploration in an area that may mark the eastern extent of the Million Mounds region.

Established in 2009, the U.S. Geological Survey’s Coral Assessment Network (USGS-CAN) provides data on coral-growth (calcification) rates throughout the Florida Keys. Pictured here is a coral at Crocker Reef in the upper Florida Keys.

Established in 2009, the U.S. Geological Survey’s Coral Assessment Network (USGS-CAN) provides data on coral-growth (calcification) rates throughout the Florida Keys and St. Croix, U.S. Virgin Islands. Pictured here is one of 30 stations located in Buck Island Reef National Monument.

This instrument, the Edgetech SB-516 or "chirp", emits acoustic signals that penetrate the sediment on the seafloor. The reflected sound is recorded and is used to create a cross-section image, or profile, of the sub-bottom.

A view of the mouth of the Klamath River where it meets the Pacific Ocean in northern California. The river runs from Oregon to California. Four dams along the Klamath are pending removal. USGS is studying coastal watershed response to dam removal, including long-term before-after/control-impact (BACI) studies.

Sediments in estuarine and marsh environments contain organic peat, or material derived from life, that plays an important role in ecosystem health. Here, USGS geologist Chris Smith of the St.

USGS science crew from Pacific Coastal and Marine Science Center work together to get the vibracorer coring device in position to collect sediment core samples off San Francisco, California.

The Rossfelder P-5 vibracorer, with its polybuterate liner visible, is secured on the deck of the research vessel Bold Horizon, awaiting deployment off the coast of California just north of San Francisco. More liners are stored in a cage off to the side.

The USGS uses the Rossfelder P-5 vibracorer to collect deep-water sediment samples from the seafloor. Here, they are heading out offshore of San Francisco with the Golden Gate Bridge in the background.
