In Port: Mayport, Florida

From May 22 through July 2, NOAA and partners will conduct a two-part, telepresence-enabled ocean exploration expedition on NOAA Ship Okeanos Explorer to collect critical baseline information about unknown and poorly understood deepwater areas of the Southeastern United States. The first cruise, from May 22 – June 6, will focus on mapping offshore U.S. Atlantic waters, from Florida to South Carolina. This cruise will set the stage for the a follow-on mission, the Windows to the Deep 2018: Exploration of the Southeast U.S. Continental Margin expedition, which will include mapping operations and remotely operated vehicle dives offshore Florida, Georgia, South Carolina, and North Carolina, from June 11 – July 2.

Dive 15: Pourtales Terrace Sinkhole

Dive 15 will survey the biology and geology of a large, unexplored sinkhole off the Pourtales Terrace to a depth of 500 meters (~1,640 feet), starting at 8:15 AM, CDT. The closest historical dive was conducted over 4 kilometers (2.5 miles) away. Other sinkholes surveyed on the Pourtales Terrace have hosted diverse communities of invertebrates and fishes. Time permitting, Deep Discoverer will spend the latter part of the dive surveying the top of the Pourtales Terrace. Today’s dive is the final dive of the NOAA Ship Okeanos Explorer Gulf of Mexico 2018 expedition. For more information about this expedition, visit:

Dive 14 Complete

Dive 14 surveyed the biology and geology of Escarpment Canyon Ridge, an unexplored narrow ridge feature off a system of canyons on the southern end of the West Florida Escarpment, to a depth of ~2,400 meters (~7,875 feet). NOAA Ship Okeanos Explorer observed a variety of organisms and likely the highest-density coral community we have seen so far on this expedition. The final dive of the Gulf of Mexico 2018 expedition is tomorrow. For more information about this expedition, visit:
