Page 57 of 76 August 2017 / st 57 HUGIN AUV for Sweden's Unmanned Marine Research The University Of Gothenburg has chosen Kongsberg Maritime's HUGIN AUV to expand Sweden's capabilities in the field of marine research using unmanned platforms. The University of Gothenburg has chosen a HUGIN configuration rated to 3,000 m, with a range of up to 300 km. The AUV is due for delivery in Feb- ruary 2018 and will feature an ad- vanced Kongsberg navigation system in addition to an extensive package of Kongsberg and third-party instruments and sensors. Kongsberg will also deliv- er a HUGIN operator station, payload operator station and acoustic position- ing operator station for communica- tion and full control of the HUGIN and payload from the mothership. Manned Sub for Bahamas Deep-Sea Survey OceanGate Expeditions and The Cape Eleuthera Institute are embarking on a Bahamas Deep Sea Survey of the twilight zone of the Exuma Sound us- ing the manned submersible Cyclops 1. Beginning October 2017, with mul- tiple weeks of diving each season over a year, the exploration aims to uncover new details on deep-sea sharks and the variety of species that inhabit the wa- ters off the Great Bahama Bank Conti- nental Shelf. OceanGate will provide the sub- mersible and dive crew, while The Cape Eleuthera Institute will share the breadth of scientific knowledge of their content experts and their facilities in the Bahamas. New Trend in Melting of West Antarctic Ice Sheet An ice sheet surface twice the size of California melted in one summer in what could become a regular occur- rence. The West Antarctic Ice Sheet experienced substantial surface melt through the austral summer of 2015 to 2016 during one of the largest El Niño events of the past 50 years, according to scientists who had been conducting the first comprehensive atmospheric measurements in the region since the 1960s. The team conducting the ARM West Antarctic Radiation Experiment, led by researchers at Scripps Institu- tion of Oceanography, reports that the melting caused by warm air bearing moisture and extensive cloud cover was likely delivered by El Niño over the ice sheet. Melted snow was spotted over most of the Ross Ice Shelf, a thick platform of floating ice that channels about a third of the ice flowing from the West Antarctic Ice Sheet into the ocean. The West Antarctic Ice Sheet rests on bedrock that is below sea level and is protected by a fringe of floating ice shelves. The melting and disintegration of these ice shelves would accelerate the flow of ice into the ocean. Were the ice sheet to melt completely, as probably occurred during the Earth's last interglacial period about 125,000 years ago, it contains enough mass to raise global mean sea level by 3 m.
