NOAA Ocean Exploration supports research expeditions to explore previously unvisited areas of the ocean. We provide partnership coordination, funding, staff, tools, and expertise needed to develop mission plans that deliver rigorous, systematic observations and documentation of biological, chemical, physical, geological, and archaeological aspects of the ocean.

Follow expeditions supported by our office, including those on NOAA Ship Okeanos Explorer, while they are underway or trace the activities and discoveries of past expeditions. For each expedition covered on the website, you’ll find information ranging from expedition plans and feature stories to educational materials and expedition daily updates, videos, and images.

Beyond the Blue: Papahānaumokuākea Mapping
Current Expeditions & Projects

In June, July, and August, NOAA Ocean Exploration will conduct two exploratory ocean mapping expeditions on NOAA Ship Okeanos Explorer focused on waters generally deeper than 200 meters (656 feet) in and around Papahānaumokuākea Marine National Monument. The ship will return to Papahānaumokuākea in October and November for a third mapping expedition.

NOAA Ocean Exploration 2024 Expeditions

NOAA Ocean Exploration works with partners to explore previously unknown areas of our ocean, making discoveries of scientific, economic, and cultural value and supporting innovations in exploration tools and capabilities. In 2024, projects will take place in the North and South Pacific oceans and in deepwater areas around Puerto Rico and the U.S. Virgin Islands.

May 2024 – November 2024; April 2025 – October 2025

Beyond the Blue: Illuminating the Pacific is a multifaceted science campaign designed to raise collective knowledge, understanding, and appreciation of waters in the Pacific Islands region through coordinated mapping and exploration expeditions, data management and sharing, strategic partnerships, and outreach and engagement. In 2024, NOAA Ocean Exploration began work with partners to conduct multiple expeditions on NOAA Ship Okeanos Explorer, lead outreach and education activities and events, and build additional partnerships in the Pacific Islands region in support of Beyond the Blue.

NOAA Ocean Exploration 2023 Expeditions

NOAA Ocean Exploration works with partners to explore previously unknown areas of our ocean, making discoveries of scientific, economic, and cultural value and supporting innovations in exploration tools and capabilities. In 2023, projects will span the globe, from exploring hydrothermal vents along the Mid-Atlantic Ridge to diving deep in the waters off Alaska, using new technologies to hunt for methane seeps off the U.S. West Coast, and searching for World War II cultural resources in the Gulf of Mexico and Pacific.

2023 Seascape Alaska Expeditions
May 2023 – September 2023

From May through September 2023, NOAA and partners conducted a series of telepresence-enabled ocean exploration expeditions on NOAA Ship Okeanos Explorer to improve knowledge about unexplored and poorly understood deepwater areas offshore Alaska, with a particular focus on the Aleutian Islands, Gulf of Alaska, and Aleutian Trench.

EXPRESS: West Coast Exploration

From October 2022 through December 2023, NOAA Ocean Exploration and partners will conduct a series of five telepresence-enabled ocean exploration expeditions on NOAA Ship Okeanos Explorer to improve knowledge about unexplored and poorly understood deepwater areas of the U.S. West Coast from Southern California to Washington.
