Campaign to Address Pacific monument Science, Technology, and Ocean NEeds (CAPSTONE) (EX1504-EX1708)

2015 - 2017

In July 2015, NOAA and partners initiated CAPSTONE – the "Campaign to Address Pacific monument Science, Technology, and Ocean NEeds." CAPSTONE was a major multi-year foundational science effort focused on deepwater areas of U.S. marine protected areas in the central and western Pacific.

With expeditions on NOAA Ship Okeanos Explorer conducted in 2015, 2016, and 2017, CAPSTONE resulted in timely, actionable information to support decision-making based on reliable and authoritative science. It also served as an opportunity for the nation to highlight the uniqueness and importance of these national symbols of ocean conservation.

Eighteen total expeditions, some with multiple legs, were completed on Okeanos Explorer in U.S. marine national monuments and national marine sanctuaries in the central and western Pacific in support of CAPSTONE. These telepresence-enabled expeditions included remotely operated vehicle (ROV) dives and multibeam sonar mapping operations. Expedition dates, numbers and names, operational modes, and ports of call were as follows:

Why Explore Pacific Marine Protected Areas?

The central and western Pacific marine national monuments and national marine sanctuaries encompass over 742,000 square miles of emergent land, coral reef, ocean, and maritime heritage resources. They contain some of the last relatively pristine marine ecosystems on the planet and harbor numerous protected species, as well as undiscovered shipwrecks and cultural landscapes sacred to the indigenous peoples of the Pacific.

Their designation is unprecedented in terms of geographic scope, ecological value, and national symbolism for ocean conservation. However, their remoteness creates substantial challenges. Most deep-water areas remain poorly known and are of high interest to federal and state agencies with research and management responsibilities.

CAPSTONE was intended to provide a foundation of publicly accessible baseline data and information from U.S. marine protected areas in the central and western Pacific. Specific science themes of CAPSTONE included:

  • Acquire data to support priority monument and sanctuary science and management needs;
  • Identify and map vulnerable marine habitats – particularly high-density deep-sea coral and sponge communities;
  • Characterize seamounts in and around the Prime Crust Zone (PCZ). The PCZ is the area of the Pacific with the highest concentration of commercially valuable deep-sea minerals;
  • Investigate the geologic history of Pacific seamounts, including potential relevance to plate tectonics and subduction zone biology and geology; and
  • Increase understanding of deep-sea biogeographic patterns across the Central and Western Pacific.

Education Themes

Education theme pages provide the best of what the NOAA Ocean Exploration website has to offer to support educators in the classroom during this expedition. Each theme page includes expedition features, lessons, multimedia, career information, and associated past expeditions. Note that for many of the CAPSTONE expeditions, specific educational resources are available in association with an individual expedition web presence.
