The NOAA Office of Ocean Exploration and Research (OER) supports research expeditions to explore previously unvisited areas of the ocean. OER provides 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 OER-supported expeditions, 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 mission plans and background essays to educational materials and mission logs, expedition daily updates, videos, and images.
