Exploring the Deep Sea: how new technology is giving us unprecedented access to our planet’s largest ecosystem
Dr Kerry Howell is Associate Professor in deep sea ecology at Plymouth University
The deep sea is the largest ecosystem on earth. From the earliest days of the Challenger Expedition our understanding of the deep sea has been limited by the technology available to us to study it. Our knowledge of the shape of the seafloor was originally based on soundings taken with lead lines, and knowledge of the animals that live on the sea bed has been largely pieced together from what we can bring up in a trawl.
We have learned a lot. We understand that the seafloor is marked by great mountain ranges, and trenches. We know that the range of species we find in the deep sea changes with geographical region and with depth. But our knowledge of finer scale patterns is limited. However, in the last 50 years technological developments have opened up our ability to study this environment. The use of manned submersibles, and more recently robots, have allowed us to observe animals in their own environment. We can now study more challenging terrain such as the slopes of underwater mountains, and canyon systems. Our ability to map the seafloor has been greatly enhanced by the use of satellite measurements and acoustic systems.
Our next great challenge is how to interpret the vast datasets we can now acquire. Here again technology, in the form of artificial intelligence and computer vision, will facilitate the next great leap in our understanding.
Dr Kerry Howell is Associate Professor in deep sea ecology at Plymouth University, and head of the Deep Sea Conservation Research Unit. She is an expert in deep-sea ecology and marine conservation. Her research is focused on understanding patterns in seafloor biodiversity (where animals are found on the deep-sea floor, and why they are found where they are). Her research is used to help make decisions around how we use the deep-sea environment, particularly in the design of marine protected area networks.
Kerry has studied the deep-sea fauna of the North East Atlantic for more than 18 years, working on seamounts, canyons, the continental slope and abyssal plain. She has lead several major expeditions and dived in a manned submersible. Her group are currently pioneering the use of artificial intelligence to interpret image data from autonomous underwater vehicles (robots).
PLEASE NOTE SECURITY MEASURES FOR ENTERING DOCK GATE 4
Visiting the NOC: As the NOC is located within the Port of Southampton and entry is via Dock Gate 4 Port Security require all visitors bring along with them their confirmation ticket and a valid form of photographic ID (Driving License / Passport). The Port of Southampton is the Strategic Authority for the implementation of security within the port area where the NOC is located.
Parking at NOC
There are a number of designated visitor parking spaces available at NOC. If these are full after 5pm please drive to the staff car parks barriers, access can be given by pressing the intercom button in the box next to the barrier, on requesting entry you will be asked for Name and Car Registration number and the barrier will be lifted.
Please do not park in areas not designated for parking and ensure roadways are kept clear.
