US Still Processing Atlantic Seismic Permits

said on Monday.Atlantic coastal state lawmakers, businesses and conservation groups are adamant that Interior should not allow seismic testing - a process that often uses powerful air guns to map resources below the ocean floor - arguing the surveys hurt marine life, such as the endangered North Atlantic right whale.Newly confirmed Interior Secretary David Bernhardt said last week the agency’s five-year plan for oil and gas drilling on the Outer Continental Shelf (OCS) would be sidelined indefinitely after a March court ruling blocked drilling in the Arctic and part of the Atlantic Ocean

Waters West of Europe Drive Ocean Overturning

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 study period.These findings can help scientists better predict what changes might occur to the MOC and what the climate impacts

Nine US States Seek to Stop Atlantic Seismic Testing

.Seismic testing uses air gun blasts to map out what resources lie beneath the ocean. Conservationists say the testing, a precursor to oil drilling, can disorient marine animals that rely on fine-tuned hearing to navigate and find food. The tests lead to beachings of an endangered species, the North Atlantic right whale, they say.New York Attorney General Barbara Underwood said the tests would harm marine species, jeopardize coastal ecosystems and pose a "critical threat" to the natural resources, jobs and lives of New Yorkers. "The Trump administration has repeatedly put special interests

US Government Sued Over Atlantic Seismic Testing

to five companies to conduct seismic airgun tests beneath a vast region off the East Coast. The permits allow marine wildlife to be harassed but not killed.Conservationists say the testing, a precursor to oil drilling, can cause disorientation that leads to beachings of an endangered species, the North Atlantic right whale.U.S. President Donald Trump is pursuing increased petroleum drilling as part of an "energy dominance" policy. A proposal to open nearly all U.S. waters to offshore drilling, announced in January, is pending."The Trump administration has steamrolled over objections of

and lifespan costs. Such a ship will in a European context become a unique platform for marine research and polar exploration in the Arctic regions at an attractive price.Like the R/V DANA IV the new research vessel will be designed for operations in icy waters in both the Baltic Sea and the North Atlantic. The vessel should be classed to Polar Code PC B 6/7 as well as comply with high standards for low level of underwater radiated noise during scientific operations.The ship will be designed with an efficient fishing gear configuration and will have several laboratories. Also, the vessel will be

Underwater Glider Goes Searching for North Atlantic Right Whales

with JASCO’s OceanObserver intelligent acoustic monitoring system in the Gulf of Saint Lawrence.With the support of Dalhousie University and the Ocean Tracking Network, the glider was deployed September 15 in the Orpheline Channel on a six-week test mission to attempt to detect and record North Atlantic right whales. In 2017, 12 individuals of this endangered species died in the Gulf, likely as a result of ship strikes and entanglements in fishing gear.The 1.5-meter-long Slocum glider is a buoyancy driven underwater drone that rises and dives in the water to propel itself forward while gathering

Future USS South Dakota Delivered to US Navy

South Dakota (BB 57) was commissioned as the lead ship in its class. The four ships of the South Dakota class are considered the most efficient battleships built under the limitations of the Washington Naval treaty. South Dakota served in the Pacific and Atlantic as a carrier escort and patrolled the North Atlantic with the British navy. During the ship's second tour in the Pacific, it helped to cripple the Japanese navy during the Battle of the Philippine Sea before helping to bombard shore defenses at Okinawa and preparing for an eventual invasion of the Japanese home islands.Virginia-class submarines

Partners Aim to Disrupt the USV Market

Seer Marine Headquarters in Abu Dhabi.The partners are looking to convert Rafnar’s Embla RHIB platform into a manned and unmanned surface vessel (USV) in turn making it one of the most stable USV platforms of its size in the world. Embla earned its reputation in the industry when it crossed the North Atlantic from Iceland to Gothenburg unsupported, tackling up to 6-meter waves over a 1,357 nautical mile distance.While the partnership focuses primarily on offering future USV platforms with the Rafnar ÖK Hull technology, the companies also agreed to a cooperation for the production of Rafnar vessels

;s vessels operate in the Saint Lawrence Estuary, where they may come across beluga, harbor porpoise, minke, blue, fin, and humpback whales. Several vessels also navigate in the Gulf of St. Lawrence and on the Canadian and U.S. East Coast, where they could also come across dolphins, pilot whales, and North Atlantic right whales.MMON initiated the maritime industry’s participation in the data collection about marine mammals in 2015 with Groupe Desgagnés and Canada Steamship Lines, a division of the CSL Group. Green Marine subsequently became a part of the project financed by the Government of
