Forum ROV to Support Arctic Research

also supplied by Forum.“The Comanche ROV will represent a pivotal equipment of the research icebreaker CCGS Amundsen. In 2020, it will be deployed at several locations spanning a latitudinal gradient from 58° to 77°N to study deep-water corals and cold seep eco-systems of the northern Labrador Sea and Baffin Bay. The project will generate critical knowledge of biodiversity and marine habitats needed for key ocean conservation initiatives in Canada”, said Dr. Alexandre Forest, Executive Director of Amundsen Science.The new Comanche ROV will be manufactured at Forum’s facility

Waters West of Europe Drive Ocean Overturning

Iceland and Irminger basins. In a departure from the prevailing scientific view, the study shows that most of the conversion from warm to cold water—or ‘overturning’ and its month-to-month variability—is occurring in regions between Greenland and Scotland, rather than in the Labrador Sea off Canada, as many past modeling studies have suggested.Overturning variability in this northeastern section of the North Atlantic was seven times greater than in the Labrador Sea, and it accounted for 88 percent of the total variance documented across the entire North Atlantic over the 21-month

Full-Depth Current Profiling Around the Global Ocean

monitored boundary currents off Canada at 53°N. Across their persistent section defined by 3–5 moorings, the scientists repeated 12–15 LADCP stations during 13 cruises. As a result, data from 150 LADCP stations supplemented the moorings to describe the overturning contribution from the Labrador Sea. Strong currents were seen at various levels. In particular, the LADCP data showed a high-speed core near the deep-sea floor. Its waters had originated in the Nordic Seas.Full-depth LADCP profiles are well-resolved vertically and can have finer horizontal spacing than a moored array. The flexibility

TGS, PGS Team Up on Eastern Canada Seismic

Eastern Canada with plans to acquire more than 36,000 km of 2D seismic data, in partnership with PGS, utilizing two vessels during the 2016 acquisition season. The M/V Sanco Spirit and M/V Atlantic Explorer, utilizing the PGS GeoStreamer technology, will acquire seismic and gravity data in the Labrador Sea, Newfoundland Orphan-Flemish Pass basins and Grand Banks areas. Data acquisition will commence during late May 2016.  Pre-processing of the initial GeoStreamer signal will be performed by PGS following which TGS will perform data processing with final data available to clients in Q3 2017

to be completed in Q2 2016.   In addition to the 3D MultiClient programs, the Atlantic Explorer and Sanco Spirit continued to build on the JV's existing MultiClient 2D library offshore Newfoundland and Labrador by acquiring more than 27 000 line kilometers of 2D GeoStreamer data in the Labrador Sea, Orphan Basin and Southern Grand Banks. The MultiClient 2D library in the area now consists of more than 110 000 line kilometers of GeoStreamer data.

Arctic Sea Ice Sets Record Low Extent at Winter Maximum

extent of just 14.54 million square kms (5.61 million sq miles) on Feb. 25 - slightly bigger than Canada - and is now expected to shrink with a spring thaw.   "This year's maximum ice extent was the lowest in the satellite record, with below-average ice conditions everywhere except in the Labrador Sea and Davis Strait," the U.S. National Snow and Ice Data Center (NSIDC) said in a statement.   A late season surge in ice was still possible, it said. The ice was 1.1 million sq kms smaller than the 1981-2010 average, and below the previous lowest maximum in 2011.   With the return

Offshore Eastern Canada Seismic Survey Expansion by TGS

2D surveys offshore Eastern Canada with plans to acquire more than 30,000 km of seismic data, in partnership with PGS, utilizing two vessels during the 2014 acquisition season. The M/V Sanco Spirit, utilizing the PGS GeoStreamer® technology, will acquire seismic and gravity data in the Labrador Sea and Northeast Newfoundland-Flemish Pass areas. Data acquisition will commence during June 2014. This project will provide valuable data covering expected Areas of Interest (AOIs) to be released by Canada's Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB) as part of the new land tenure

Three New Offshore Seismic Surveys for TGS

Shetland Rona Ridge 2013 (RR13) is a 2,420 km2 3D survey that will provide the industry's first 3D data in the highly prospective UK West Shetland Basin.  Data processing will be performed by TGS with initial data available to clients in Q4 2013 ahead of the UK 28th Licensing Round. The Labrador Sea Deep Basin The 2D survey covering 3,000 km and the Labrador Sea 2D Infill survey covering 7,100 km will complement and infill the existing 22,167 km of 2D data acquired in 2011 and 2012. These surveys will further define and delineate the Henley, Chidley and Holton Basins. Both surveys will

in Canada's Far North." The CCGS Amundsen is one of the few Canadian icebreakers to have a dual purpose. In winter, she is assigned to the CCG icebreaking program whereas every summer, she is chartered by ArcticNet, a scientific consortium. This year, the CCGS Amundsen will navigate the Labrador Sea, Baffin Bay, the Northwest Passage and the Beaufort Sea to study the impact of climate change and modernization on the arctic marine ecosystem. Thanks to her skilled crew and highly sophisticated equipment, the CCGS Amundsen can at all times be deployed to take part in search and rescue, pollution
