Windows to the Deep 2019: Exploration of the Deep-sea Habitats of the Southeast United States

Past Expedition

Dates
May 30 through July 12, 2019
Location
Atlantic Ocean

Overview

From May 30 through July 12, 2019, NOAA and partners conducted 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.

Features

Windows to the Deep 2019: Exploration of the Deep-sea Habitats of the Southeastern United States was a 38-day, two-leg, telepresence-enabled expedition on NOAA Ship Okeanos Explorer to collect data on priority exploration areas identified by the ocean management and scientific communities.

Although no active gas bubbling was observed during Dive 19, the dense patches of live Bathymodiolus childressi mussels and associated bacterial mats are indicators of fluid seepage. Such ecosystems rely on methane or hydrogen sulfide produced during the bacterial breakdown of methane for their metabolic processes, meaning that an active methane system must be present below the seafloor. Red laser dots are separated by 10 centimeters (3.94 inches).
On the final remotely operated vehicle (ROV) dive of Windows to the Deep 2019, NOAA Ship Okeanos Explorer’s 100th ocean exploration mission, the ROV Deep Discoverer (D2) explored the seafloor around recently discovered methane plumes near the well-studied Norfolk Seeps, the location where the U.S. Atlantic seeps story first began in 2012.

CCommander Nicole Manning, the sixth Commanding Officer of NOAA Ship Okeanos Explorer.
On Sunday, June 16th, 2019, in the midst of her 100th ocean exploration mission, NOAA Ship Okeanos Explorer could curiously be found in port, rather than exploring the deep sea. The occasion? A formal maritime change of command ceremony, and the official welcoming of Commander (CDR) Nicole Manning as the sixth Commanding Officer (CO) of the Okeanos Explorer.

Operations during this expedition have taken NOAA Ship Okeanos Explorer both inside and outside the Stetson-Miami Terrace Deepwater Coral Habitat Area of Particular Concern (HAPC) and the team has discovered mounds of reef-building corals no one ever dreamed of.

Two bubble streams emanating from relatively bare seafloor and framed by D2 during the Bodie Island seeps dive.  Note patchy distribution of white Beggiatoa bacterial mats in the background and Bathymodiolus shell debris and live mussels in the foreground, along with anemones.
During Dive 14 of the Windows to the Deep 2019 expedition, NOAA’s remotely operated vehicle (ROV) Deep Discoverer, also known as D2, explored cold seeps arrayed along a ridge located about 62 kilometers (39 miles) offshore Bodie Island, North Carolina.

When the old television show The Twilight Zone described its namesake as a “dimension of imagination” consisting “of both substance and shadow,” it could easily have been referring to an area of the ocean by the same name. The mesopelagic zone, also known as the twilight zone, lies at 200-1000 meters (about 660-3300 feet), where the last bits of sunlight from the surface give way to total darkness.
July 6, 2019
At 920 meters (3,018 feet) depth we came upon a Chaceon crab perched above a white patch on the seafloor. A closer look revealed the patch to be a cluster of hundreds of eggs, proposed by Dr. Peter Auster (University of Connecticut and Sea Research Foundation - Mystic Aquarium) to have been deposited on the rock by a pallid sculpin.

Figure of survey area on the central Blake Plateau, mapped during the first leg of the Windows to the Deep 2019 . The seafloor mapping data revealed unique geological features in the northwestern part of the survey area, particularly a unique underwater cliff-like structure with a vertical drop of approximately 200 meters.
The first leg of the Windows to the Deep 2019 expedition conducted 24-hour mapping operations in deepwater areas offshore of the southeastern United States. After 17 days at sea, we ended the mission with new multibeam bathymetry maps of areas of the Blake Plateau.

In honor of #CephalopodWeek (and #OctopusFriday!), below is a collection of some of our favorite sightings of these highly intelligent, mobile, and charismatic invertebrates, made over the course of exploring from the Okeanos.

During Dive 5 of the Windows to the Deep 2019 expedition, we encountered a charismatic swimming jelly called a helmet jelly that was twisting and tumbling as it moved across ROV Deep Discoverer’s field of view.

We teamed up with the Octonauts to provide a behind-the-scenes look at NOAA's ocean exploration vessel in the “Octonauts and NOAA Ship Okeanos Explorer” video, giving aspiring explorers the opportunity to learn more about our ocean.

Windows to the Deep 2019 is the first live-streamed expedition that the remotely operated vehicle (ROV) Deep Discoverer (D2) will use its new suction sampler.

When someone mentions deep-sea corals, most people think of something like what they might see on a tropical shallow coral reef. But many deep-sea corals, like the colonies in this video, are more closely related to tropical sea fans than to the corals that create the structure of the reef.

This large outcrop with several large coral colonies was seen at 760 meters (2,493 feet) during the second dive of this expedition. Large corals, such as the black coral shown here can host an abundance of associates including several flytrap anemones (Actinoscyphia aurelia) and squat lobsters. These associates use the coral to get farther off the seafloor into the nutrient-delivering currents.
In the deep sea, we encounter many other corals: lace corals, soft corals, gold corals, and black corals.

There is perhaps no greater potential for archaeological discoveries in U.S. waters than along the Eastern Seaboard.

In 2016, NOAA launched a new four-year initiative to study deep-sea coral and sponge ecosystems across the Southeast United States, a region that includes the U.S. federal waters of the Gulf of Mexico, South Atlantic Bight, and Caribbean Sea.
