Ecosystems: EXPRESS
Expanding Pacific Exploration and Research
Learn how our multi-agency team is mapping uncharted waters and exploring deep-sea ecosystems off the west coast of the United States.
EXPRESS geonarrativeThe EXPRESS Campaign
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.
Expanding Pacific Research & Exploration of Submerged Systems: 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 (Expanding Pacific Research and Exploration of Submerged Systems) 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: May 27, 2021Status: ActiveResources: EXPRESS
Along the U.S. west coast, the Pacific Ocean, ocean floor, and winds above contain potentially vast energy and mineral resources. Developing these resources safely and wisely requires detailed information for each area of interest. One goal of EXPRESS is to inform ocean energy and mineral resource decisions.

At our Science Center, we have a suite of laboratories that we affectionately call the "sed lab." The sed lab really consists of 5 labs, arranged next to each other to allow our lab technicians to easily move back and forth between them while processing sediment samples: Sediment Preparation Lab, Fine Particle Analysis Lab, Settling Tubes Lab, Fume Hood Lab, and Carbon Analysis Lab.

From June 12 to July 3, 2019, the USGS sailed 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...

Expanding the repertoire of electron acceptors for the anaerobic oxidation of methane in carbonates in the Atlantic and Pacific Ocean
Authigenic carbonates represent a significant microbial sink for methane, yet little is known about the microbiome responsible for the methane removal. We identify carbonate microbiomes distributed over 21 locations hosted by seven different cold seeps in the Pacific and Atlantic Oceans by carrying out a gene-based survey using 16S rRNA- and ...

Various water column variables, including CTD (Conductivity Temperature Depth) data were measured at selected depths from sites offshore of California and Oregon from October to November 2018 during NOAA cruise SH-18-12 on R/V Bell M. Shimada (USGS field activity 2018-663-FA).
Expanding Pacific Exploration and Research
Less than 20% of the world's oceans have been explored. A global initiative seeks to change that, by pledging to complete detailed mapping of 10% of the seafloor by the year 2030. The United States is contributing to this effort in part through a collaborative team of federal, state, and nongovernment organizations to map, explore, and characterize waters along the US Pacific coast...
