The 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.

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
