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.

A bar graph shows days at sea by agency and purpose for federal government fiscal years 2017, 2018, 2019, and 2020.

EXPRESS Days-At-Sea by Agency and Purpose. This graph shows 326 days at sea across 9 vessels​:

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

An offshore map shows locations of ROV dives and a star where a sediment core was collected, with photos of the core.

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.

Virtual Workshop to Identify National Ocean Exploration Priorities in the Pacific, July-September 2020

In partnership with NOAA’s Office of Ocean Exploration and Research (OER), the Consortium for Ocean Leadership organized the Workshop to Identify National Ocean Exploration Priorities in the Pacific. This workshop was hosted virtually. A virtual opening plenary was held on July 10, 2020. A series of virtual breakout sessions were held in July and August 2020, and a virtual closing plenary was held on September 21 and 22, 2020.
