New DEEP Sea Underwater Habitat Announced

New DEEP Sea Underwater Habitat Announced

Handout render of DEEP Sentinel seafloor scene. A new deep-sea habitat project has been launched by ocean technology and exploration company, DEEP, which has announced its intention to create a permanent human presence under the oceans by 2027. The project is already two years in development, with its base located at the former British National Diving and Activity Centre (NDAC), an 80m-deep, 600m-long flooded quarry in Gloucester, England, which suddenly announced its closure in February 2022. The centrepiece of DEEP’s project is Sentinel, a customisable capsule system designed to be ‘modular, scalable, autonomous, recoverable, re-configurable and re-deployable.’ Sentinel can be tailored to the individual needs of its users, be that a single installation or a network of segments interlinked to form a ‘deep-sea village’, and DEEP claims it will be installed on the sea floor with minimum disturbance to the surrounding ecosystem. Built using an innovative construction method employing robotic welding arms, which
