New Depth Map Over the Arctic Ocean

has been completed under the auspices of the Regional Center for the Arctic and North Pacific Ocean of The Nippon Foundation-GEBCO Seabed 2030 Project. This Regional Center is one of four Seabed 2030 centers covering the world ocean and is run jointly by Stockholm University and the University of New Hampshire. Scientists and map-makers from 15 countries participated in the work, including all circum-Arctic nations.The new IBCAO Ver. 4.0 has increased the area mapped of the Arctic Ocean from 6.7% in the previous release of Ver. 3.0 in 2012 to 19.6%.“IBCAO Ver. 4.0 represents the 2020 contribution

Fast-moving Waterfalls in the Deep Sea

of sediment that flow down these channels also pose a hazard to networks of seafloor cables that underpin global communications, including the internet.An international research team, including NOC, Universities of Durham, Southampton and Hull (UK), Geological Survey of Canada, and University of New Hampshire (USA), performed the most detailed repeated mapping of any submarine channel to date. Time-lapse surveys acquired over nine years in Bute Inlet, British Columbia, revealed a dramatic series of up to 30 m-tall, steep cliffs (called ‘knickpoints’) that resemble waterfalls in rivers

Manatua Consortium Approves Cable Lay

French Polynesia, Avaroa Cable Limited (ACL) in the Cook Islands, Telecom Niue Limited (TNL) in Niue, and Samoa Submarine Cable Company (SSCC), in the Independent State of Samoa, met in Apia this week to approve detailed installation plans.The cable is already in the region following manufacture in New Hampshire, USA by submarine cable industry leader SubCom, who was successful in the extensive supplier selection process held in 2018.  Transfer of the 3700km cable from the delivery freighter Thorco Liva onto specialist cable laying vessel SubCom Reliance is currently underway.  Cable lay operations

Searching for Shipwrecks

and natural features such as sinkholes, fish habitats, and interesting geological formations.During the two-week expedition, researchers mapped areas within the sanctuary with a multibeam sonar system aboard autonomous surface vehicle ASV BEN (Bathymetric Explorer and Navigator) from University of New Hampshire’s Center for Coastal and Ocean Mapping. BEN is a state-of-the-art robotic vehicle that looks like a small yellow boat. Unlike most boats, though, it doesn’t carry people; instead, it is piloted by crew members back on shore. Using sonar and GPS, BEN collects data about the lake bottom

The red and yellow objects are parts of a communication system consisting of antennas suspended under ice from a buoy installed on top of the ice.  Graphic by ADAC.

LRAUV: Arctic Oil-Spill-Mapping Robot Put to the Test

will process the navigation performance data from the test and will tune the navigation algorithms according to the results. Then the team will make three communication buoys and will test them with the robot under ice. The team is targeting to conduct the under-ice test in a large lake in New Hampshire, the Eastern Great Lakes, or Alaska during the winter season.ADAC plans to complete all rigorous testing – including under-ice tests – and the construction of communication relay buoys by the end of June 2019
