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.

October to November 2020: The deep sea is a vast reserve of mystery and possibility. The residents of the deep sea, and the minerals that compose its floor, are of growing importance to modern society. Microorganisms offer significant biopharmaceutical and industrial promises and some of deep-sea minerals are increasingly rare and in-demand.
