Ecosystems: EXPRESS
Science Center Objects
The continental shelf and slope offshore California, Oregon, and Washington are home to deep-sea corals, chemosynthetic communities, and other sensitive habitats that could be impacted by the development of energy and mineral resources. The EXPRESS campaign will map and characterize these special areas to help guide ocean management decisions.
USGS research oceanographer Nancy Prouty and a team of water chemistry specialists collected water column samples from several deep-sea locations off Washington, Oregon, and California.
The potential direct, indirect and cumulative impacts on the human, coastal and marine environments must be evaluated in order to make environmentally sound decisions about managing energy and mining activities and developing mitigation measures. EXPRESS will explore, map, and measure regions of interest on the U.S. west coast outer continental shelf in order to improve computer models of benthic habitats.
EXPRESS priorities that contribute to ecosystem assessments include:
- Locate and characterize deep sea coral, sponge, and chemosynthetic communities, including associated fish populations
- Create a seamless map with benthic habitat classifications for targeted regions
- Extend bathymetry and backscatter coverage to high priority areas

Date published: July 15, 2019Status: ActiveEXPRESS: Expanding Pacific Research and Exploration of Submerged Systems
EXPRESS is a multi-year, multi-institution cooperative research campaign in deep sea areas of California, Oregon, and Washington, including the continental shelf and slope. EXPRESS data and information are intended to guide wise use of living marine resources and habitats, inform ocean energy and mineral resource decisions, and improve offshore hazard assessments.

Date published: June 19, 2019Status: ActiveSeeking the Seeps
From June 12 to July 3, 2019, the USGS is sailing onboard Schmidt Ocean Institute’s R/V Falkor with several other partners, seeking methane seeps along the seafloor of several underwater canyons off the coast of Oregon and Washington. On this cruise, USGS scientists will seek to understand how much methane is coming out of these seeps, how it travels through the water column, and its ultimate...
Mounted Niskin Bottles
The two Niskin bottles used to collect deep-sea water samples are mounted to the bottom of ROV Jason and can be triggered by the ROV’s manipulator arms.
Squat-lobster Eumunida picta
The bright red squat-lobster (Eumunida picta) is often seen among the live coral colonies, with their arms raised to grab anything edible that passes by.

Blackbelly rosefish – these striking fish are fairly common in the rocky canyon habitats. Related to scorpionfish, the blackbelly rosefish is an ambush hunter and possesses venomous dorsal spines to deter predators.
