The DTRA's Blowfish Project demonstrated its capabilities during the Joint Exercise Arctic Edge 2020 in Juneau, Alaska in February 2020. During the exercise, Blowfish engaged the system’s underwater neutralization disruptor against surrogate underwater explosive threat targets.

Arctic Rays Launches High-torque Pan & Tilt

Arctic Rays, LLC has released a high torque version of its miniature Hammerhead pan and tilt for use on multiple platforms, including ROVs, HOVs, ASVs, landers and fixed platforms. In addition, the standard 316 SS unit can be supplied in 6061 Aluminum for weight critical applications. The original Hammerhead and the new Hammerhead XT are both available as single axis rotators.The new Hammerhead XT provides a rated torque of 13.6 N-m (10 ft-lbs) in a compact envelope measuring only 6.59” (167mm) tall x 5.02” (128mm) wide x 2.5” (64mm) deep.  Hammerhead XT features absolute

Researchers Use AI to Map Marine Environments

improve monitoring of the UK’s vast marine territories using high tech sonar.  SEA led the project and provided simulated sonar data to train and test the AI algorithms developed by the IMI.The technology could also be potentially used for ocean tomography across entire ocean basins, like the Arctic, to study the effects of climate change on the oceans and better enable the sustainability of human activities in fragile environments and ecosystems.Senior Lecturer Dr Philippe Blondel, from the University’s Center for Space, Atmospheric and Oceanic Science, worked on the project alongside

Prior to that, he served as the Naval Deputy to NOAA for the Oceanographer of the Navy in Washington D.C. and served as a key advisor to both NOAA and the Navy to facilitate a strong partnership on topics that included Arctic sensing and modeling, underwater unmanned systems, data sharing and budget.Reiss earned his M.S. in Air & Ocean Physical Sciences from the Naval Postgraduate School, and a B.S. in Oceanography and Meteorology from the U.S. Naval Academy. He is a four-time recipient of both the Meritorious Service

Fugro Mapping Arctic Waters off Norway

The Norwegian Hydrographic Service has awarded Fugro another hydrographic survey contract as part of the MAREANO seabed mapping program, financed by Norway’s Ministry of Trade, Industry and Fisheries, and the Ministry of Environment.Fugro said it has already completed 10 surveys for the program since 2006 and acquired over 140,000 km2 of data. This latest survey will collect high-resolution, high-density multibeam echosounder and sub-bottom data to produce seamless datasets for the Norwegian mapping program. The fieldwork will run from June to late October this year.The survey area covers

What Did Scientists Learn from Deepwater Horizon?

in the marine environment.Though the authors caution that the lessons learned from the Deepwater Horizon release may not be applicable to all spills, the review highlights advances in oil chemistry, microbiology, and technology that may be useful at other deep-sea drilling sites and shipping lanes in the Arctic. The authors call on the research community to work collaboratively to understand the complex environmental responses at play in cold climates, where the characteristics of oil are significantly different from the Gulf of Mexico.“Now we have a better sense of what we need to know,” Kujawinski

The survey of Ikka Fjord was conducted between the 20th and 21st June 2019, with the first day spent partly on training and familiarizng the cox with the survey requirements and reconnaissance to identify navigation hazards in the fjord caused by the columns and rock skerries as well as some acquisition. The second day was spent entirely on acquisition followed by demobilization of the spread from ‘Siku’. Image: Courtesy Norbit

Mapping the Ikaite Columns of the Ikka Fjord, SW Greenland

is found in areas outside of the Fjord, generally in sediments where an identified calcite inhibitor exists facilitating the formation of Ikaite meaning its presence can be explained. Without an inhibitor common calcite, not ikaite would otherwise form.In recent years ikaite has been found forming in Arctic and Antarctic sea ice. This is an especially interesting development as there are no known calcite inhibitors in open marine settings where sea ice can form, suggesting that there are other methods of Ikaite formation. If we can understand the key factors for ikaite precipitation, using Ikka Fjord
