DEEP SEARCH 2019: DEEP Sea Exploration to Advance Research on Coral/Canyon/Cold seep Habitats

Past Expedition

Dates
April 9 to 30, 2019
Location
Atlantic Ocean

Overview

From April 9 to 30, 2019, NOAA and partners at the Bureau of Ocean Energy Management and the U.S. Geological Survey conducted a research expedition on NOAA Ship Ronald H. Brown to collect critical baseline information about deepwater habitats offshore the U.S. Mid- and South Atlantic coasts.

Features

The 2019 DEEP SEARCH mission was a great success. We battled some stormy weather that forced us to run and adapt our plans, but the whole team worked together and did an exceptional job in pulling off this complex research expedition.
May 23, 2019
Scientists discovered chemosynthetic vestimentiferan tubeworms while exploring methane cold seeps on a research expedition in the Atlantic Ocean off of the U.S. southeast coast last month, marking the first time that tubeworms have ever been observed in this part of the Atlantic.

This Paragorgia coral was seen on a boulder near the Cape Fear seep site.
The end has snuck up on us yet again. Somehow five days have elapsed since my last update, and we’re headed to the dock tomorrow afternoon. In those five days though, we’ve done quite a lot.

These blackbelly rosefish were observed throughout the dive at Pea Island Seep.
With the end of the expedition in sight, Team DEEP SEARCH has been extremely busy spending our last full week at sea doing as much science as possible. After Monday’s mega-dive at Pamlico Canyon, we were back in the water no more than 5 hours later at Pea Island Seep.

This octopus was seen on Dive 5 at Pamlico Canyon.
Our dive at Pamlico Canyon was our longest yet of this expedition, clocking in at nearly 20 hours on the seafloor. The ROV began the dive at the bottom of the canyon (nearly 1,900 meters down) and spent most of the dive slowly climbing up from there, surveying the canyon’s walls and ledges.

ROV Jason is equipped with a sample “basket” that can be fitted with specific sampling equipment provided by the science team. Here, the ROV pilot places a snip of Lophelia pertusa into a biobox, which is an insulated housing designed to keep the corals with the cold water they’re collected in for the duration of the ROV dive.
When we send an ROV like Jason down into the ocean it not only provides us eyes on the seafloor with cameras but also arms with hydraulic manipulators. These manipulators provide a lot of utility to sample in different ways while on the seafloor.
April 22, 2019
It’s been a busy week here aboard NOAA Ship Ron Brown! As is often the case with deep-sea research, Leg 1 didn’t go entirely as planned, so we made adjustments, as we’re always prepared to do.

Images like this from ROV Jason helps establish baseline habitat information, which the Bureau of Ocean Energy Management uses to understand the environments in which they operate.
BOEM’s research is primarily use-inspired, meaning it is designed to fill information needs for the Bureau. Studies like DEEP SEARCH provide valuable baseline environmental information and contribute to our understanding of the environments in which we operate.
April 15, 2019
We not only collect water column data around and above the reefs, but we also measure the near-bottom environmental conditions through time with bottom landers. These stand-alone platforms can be deployed on the deep-sea floor for several days up to a year, during which they can measure a large variety of environmental variables.
April 14, 2019
Parasitism is an important symbiosis—or interaction between two different species living in close physical association—found in marine communities. Different types of marine parasites, including worms, isopods, and copepods, infect a variety of host species, including crabs and fishes.
April 13, 2019
The two Niskin bottles used to collect deep-sea water samples are mounted to the bottom of ROV Jason and can be triggered by the ROV’s manipulator arms.
What can a bottle of water tell you? Well, if the water was collected from the deep sea, maybe a lot! We’re hoping that bottles of water collected from several sites during this cruise will give us insight into the dominant microbial processes, what food options the animals in the habitat have, and if it is possible to detect the presence of larger organisms like corals and fish from their environmental DNA (eDNA) in the water.
April 12, 2019
This crinoid was seen on Madrepora coral during Dive 1 at Richardson Hills.
This morning, ROV Jason was successfully recovered after our first dive of DEEP SEARCH 2019.
April 11, 2019
On this mission, ROV Jason will be used as a single-body system. Operating in single-body mode will allow for the ROV team to have greater operational flexibility in the high current environments of the Gulf Stream.
Jason is an ROV system designed and built by WHOI’s National Deep Submergence Laboratory and funded by the National Science Foundation. Its design gives scientists access to most of the globe’s seafloor, often for days at a time, without leaving the deck of a ship.
April 10, 2019
NOAA Ship Ronald H. Brown docked at its home port at Pier PAPA at the Federal Law Enforcement Training Center in Charleston, SC.
Just after 1:30pm today, NOAA Ship Ronald H. Brownpulled away from the dock in Charleston, SC for the official start of DEEP SEARCH 2019!
April 9, 2019
Overview of extensive chemosynthetic mussel communities colonizing carbonate and sedimented mounds at a seep site south of Norfolk Canyon.
Cold seeps create very interesting environments that provide resources and habitat for a wide variety of creatures. Bacteria and other microbes feed directly off of the gasses released (mostly methane and hydrogen sulfide), and animals like mussels and clams that have bacterial symbionts that use these chemicals also thrive there.
April 4, 2019
From April 9 to April 30, the DEEP SEARCH team will be diving daily with ROV Jason at targets indicated by yellow stars. Bathymetry data shown in full-color was collected by recent NOAA Ship Okeanos Explorer missions and by the 2018 R/V Atlantis cruise. Bathymetry data shown in muted, transparent color represents the full extent of data in the region.
From April 9 to 30, 2019, NOAA and partners at BOEM and USGS will conduct a research expedition on NOAA Ship Ronald H. Brown to collect critical baseline information about deepwater habitats offshore the US Mid- and South Atlantic.

Live Lophelia colonies are bright white to slightly pink in color, which distinguishes them from the underlying darker dead coral matrix. The dead coral is a natural part of the deep reef ecosystem, and provides valuable habitat for many associated invertebrates and fishes.
From the tip of Miami to North Carolina, the deep seafloor is comprised of hundreds of miles of rugged peaks, ledges, and mounds, which are scoured and swept clean of sediment by the ever-present, powerful Gulf Stream current. Deep-sea corals thrive in this cold, dark, hostile environment, creating large complex structures that provide shelter, feeding, and nursery habitat to countless other invertebrates and fishes.

Three-dimensional view of Keller Canyon with depths ranging from 200 to 1,600 meters. The main canyon channel carves into the continental shelf (dark red). This complex canyon has many tributary canyons.
Carved into the shelf from North Carolina through Canada are forty undersea canyons that may be 10 to 100 miles long, with some deeper than the Grand Canyon. The complex topography and geology in canyons provides many habitat types including steep walls, rocky outcrops, and ledges where sensitive deep-sea coral communities often live, as well as sedimented areas where additional fish and invertebrate species thrive.
