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.
In response to Section 2 of the Presidential Memorandum (PM) on Ocean Mapping of November 19, 2019, the National Strategy for mapping, exploring, and characterizing the United States Exclusive Economic Zone (EEZ) has been established. EXPRESS (Expanding Pacific Research and Exploration of Submerged Systems) activities focus on the Pacific EEZ. In particular, the unique partnership of EXPRESS allows federal and non-federal entities to collaborate in identified priority areas. These are directly aligned to the National Strategy outlined by the White House Office of Science and Technology Policy and Council on Environmental Quality.
EXPRESS partners include NOAA, BOEM, USGS, MBARI, and USC Sea Grant.
Priorities
- Extend bathymetry and backscatter coverage to high priority areas
- Create a seamless map with benthic habitat classifications for targeted regions
- Locate and characterize deep sea coral, sponge, and chemosynthetic communities, including associated fish populations
- Identify underwater geological hazards and evaluate their potential for generating tsunamis
- Investigate deep-sea minerals of potential industry interest
- Use the complementary capabilities of federal assets to produce integrated datasets
- Provide a foundation of publicly accessible data and information to spur further exploration, research, and management
- Engage a broad cross-section of the scientific community and the public
Fieldwork
EXPRESS partners have completed several research cruises using ships from NOAA, university, and non-profit oceanographic research institutions. More cruises are planned and under discussion. Every participating organization has contributed resources including ships, instruments, and personnel.

- > 110 ROV and 70 AUV dives
- 79 piston cores
- Actively participating organizations: NOAA (16); BOEM (2); USGS (2); MBARI

Expanding Pacific Research and Exploration of Submerged Systems (EXPRESS) is an inter-agency federal and nonfederal collaborative research effort aimed at gathering new data of the deep ocean, continental shelf and slope offshore of California, Oregon and Washington. This expansive partnership includes three federal agencies and additional principle investigators from leading research institutes.
Expanding Pacific Exploration and Research: Overview of the EXPRESS research campaign
A multi-agency team is mapping uncharted waters and exploring deep-sea ecosystems off the west coast of the United States.
Oceans cover 71% of the Earth's surface, yet little is known about these vast underwater worlds. Less than 20% have been explored. A global initiative seeks to change that, by pledging to complete detailed mapping of one-hundred percent of the seafloor by the year 2030..

The figure shows the location of remotely operated vehicle (ROV) Doc Ricketts dives conducted in September 2020, plus three images of the CT scan data from one of the collected cores. In the CT scan of the upper 80 cm of the core "DR1281 VC-870," with a zoomed in section to the right outlined in red, sections of lighter colors indicate sandy sediment and suggest horizons associated with 4 turbidites. In the lower right is a perpendicular slice through a horizon (marked in orange) showing coarse grains that are characteristic of turbidites. Previously published work identified a sand layer in a core at this same site and subbottom depth, which was determined to be associated with the January 1700 Cascadia mega-earthquake and subsequent tsunami.

Cascadia Subduction Zone Marine Geohazards
Societal Issue: Uncertainty related to rupture extent, slip distribution, and recurrence of past subduction megathrust earthquakes in the Pacific Northwest (northern CA, OR, WA, and southern BC) leads to ambiguity in earthquake and tsunami hazard assessments and hinders our ability to prepare for future events.Ecosystems: EXPRESS
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...Hazards: EXPRESS
Marine geohazards including earthquakes, landslides, and tsunamis lie offshore of densely populated areas of California, Oregon, and Washington. One goal of EXPRESS is to improve assessments of these hazards.Resources: 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.
