Hadal Ecosystem Expedition Takes Off
An international team of researchers is using the unique deepwater Hybrid ROV Nereus, and other advanced technology to explore life in the depths of the Kermadec Trench, which runs northeast from the North Island of New Zealand. The 40-day expedition, which began on April 12th, kicks off an ambitious three-year collaborative effort funded by the National Science Foundation (NSF). The goal of the project, known as Hadal Ecosystem Studies (HADES), is to conduct the first-ever systematic study of life in ocean trenches, comparing it to the neighboring abyssal plain at depths between 3,000 and 6,000 meters. Due to the extreme pressures of these deep-sea environments and the technical challenges involved in reaching them…
Hadeep and the New Hebrides Trench – Part 1
HADEEP (Hadal Environment and Educational Program) is a collaborative project based at the University of Aberdeen’s Oceanlab. The HADEEP 4 expedition was funded by the Total Foundation. This project, entitled “Trench Connection” is supporting this trip. HADEEP 2 to 4 has been a partnership between Oceanlab and NIWA in New Zealand. For the first time, researchers have taken a look at the life that thrives in one of the deepest spots in the ocean. They investigated the New Hebrides Trench, located just West of Vanuatu, and revealed that cusk eels and crustaceans teem more than 7,000m (23,000ft) down. They used cameras fitted on an unmanned lander to film the deep-sea creatures.
Schmidt Ocean Istitute Designing New Ultra-Deepwater Research HROV
Accessing to the world’s deepest ocean trenches has always been challenging and these have only been reached sporadically, leaving these areas virtually unexplored. The Woods Hole Oceanographic Institute’s (WHOI) Nereus, a proof of concept Hybrid Remotely Operated Vehicle (HROV), now being used on Schmidt Ocean Institute’s (SOI) Falkor and other research vessels, offers unprecedented access to the deepest regions for scientists, enabling systematic exploration and studies of deep trenches. There are a number of deepsea trenches at hadal depths around the globe worth exploring, highlighting to WHOI and SOI that they would have an exceedingly large area to cover with a single HROV.
Phoenix and the Remora 6000
The Remora is specially designed ultra-deepwater ROV. It was designed and built to explore and undertake specialized work at the seabed up to four miles deep. The builder of the Remora 6000, Phoenix International, is an American marine services company experienced in designing and manufacturing unmanned subsea vehicle and also in conducting complex manned and unmanned underwater operations. Phoenix is also a highly regarded operator, when it comes to wet and dry chamber underwater welding, underwater non-destructive testing, manned diving, side-scan sonar operations, underwater tooling, submarine rescue, and engineering design and integration.
