From November 29 through December 21, 2017, a team of scientists and technicians, both at-sea and shore-based, will conduct exploratory investigations into the diversity and distribution of deep-sea habitats and associated marine communities in the Gulf of Mexico basin. The 23-day expedition will focus on acquiring data on priority exploration areas identified by ocean management and scientific communities. This is the first of three expeditions planned to increase our understanding of the Gulf, with two additional cruises scheduled for Spring 2018.
Through discussions and information stemming from NOAA and other stakeholders, priority areas have been identified for exploration. This expedition will explore deep coral and sponge communities, bottom fish habitats, seamounts, undersea canyons, shipwrecks, and a variety of chemosynthetic habitats including cold seeps, mud volcanoes and brine pools. Using NOAA Ship Okeanos Explorer’s unique capabilities, we will provide scientists and audiences onshore with real-time video footage from deep-water areas in important, yet largely unknown, U.S. waters.
The ship will conduct 24-hour operations consisting of daytime remotely operated vehicle (ROV) dives and overnight mapping operations. Operations will focus on priority ROV dive sites and mapping areas throughout the Gulf of Mexico. ROV dives will include high-resolution visual surveys and limited sampling. This expedition will help to establish baseline information in the region to catalyze further exploration, research, and management activities.

The Gulf of Mexico 2017 expedition will address priority science themes and areas proposed by scientists and managers from NOAA, management agencies in the region, and the ocean science community. Operations will complement previous and planned work in the area. NOAA priorities for the expedition include a combination of science, education, outreach, and open data objectives that will support management decisions at multiple levels:
NOAA Ship Okeanos Explorer, the United States’ first and only federal vessel dedicated to exploration of our largely unknown ocean, conducts operations in a unique way, using telepresence to engage the majority of the science team on shore. Using telepresence, real-time video and other oceanographic data are transmitted through satellite and high-speed Internet pathways to scientists and stakeholders around the country.
Scientists access the live feed by standing watch in Exploration Command Centers (ECCs), tuning in to the high-definition video via Internet-2 or watching the live video on standard Internet from their home institutions. Shore-based scientists interact with the ship through a teleconference line and Internet collaboration tools. Using these communication tools, scientists and students can contribute expertise and help guide the at-sea operations in real time, extending the reach of ocean exploration to more scientists and students than could possibly be accommodated onboard.
Anyone with an Internet connection can follow along with the expedition as high-definition video of dives streams live to shore from ROV Deep Discoverer from November 30 through December 20, 2017. The same technology that allows scientists around the world to participate in the expedition from land also enables interested members of the public to experience deep-sea exploration, the wonder of discovery, and the fascination of science in real time. Additionally, mission logs, daily updates, educational materials, and multimedia elements will be added to the Ocean Explorer website throughout the expedition.
