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

EXPRESS: 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: November 12, 2020Status: ActiveSediment Lab Suite and Carbon Analysis Lab
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...

Date published: June 26, 2020CTD profiles and discrete water-column measurements collected off California and Oregon during NOAA cruise SH-18-12 (USGS field activity 2018-663-FA) from October to November 2018
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).

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.
