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.
