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

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.

Exploring the vast, remote regions of our ocean, especially in the Arctic and Antarctica, is incredibly challenging. Deploying Wave Gliders in the most energetic sea conditions on Earth will help scientists gain a better understanding and modeling of our changing planet.“In 2016

Additionally, crowd sourced bathymetry data acquired by Fugro in the North Atlantic Ocean is feeding into a regional initiative known as the Galway Statement on Atlantic Ocean Cooperation. Signed in 2013 between the U.S., Canada and the European Union, the statement provides a means for understanding the shared waters of the North Atlantic for scientific, environmental and economic

New Species Found in the North Sea

. Nevertheless, reliable information on the species' biology was still scarce. As Jan Beermann explains, "We now know that the new species, Epimeria frankei, ranges from the Mediterranean to the North Sea, whereas the old species, Epimeria cornigera, is more restricted to the northern North Atlantic. There is a small area of overlap in the North Sea were both species can be found." With the addition of E. frankei, the number of known Epimeria species in the north-eastern Atlantic increased to a total of five species.This new discovery underlines that, even today, marine biodiversity

Atlantic Ocean Circulation at Weakest Point in 1,600 Years

increase in sea level on the U.S. East Coast.When it comes to regulating global climate, the circulation of the Atlantic Ocean plays a key role. The constantly moving system of deep-water circulation, sometimes referred to as the Global Ocean Conveyor Belt, sends warm, salty Gulf Stream water to the North Atlantic where it releases heat to the atmosphere and warms Western Europe. The cooler water then sinks to great depths and travels all the way to Antarctica and eventually circulates back up to the Gulf Stream.“Our study provides the first comprehensive analysis of ocean-based sediment records

These are areas of the oceans that currently receive high inputs of atmospheric nitrogen and where there are also likely to be substantial changes in the future, with potential impacts at regional and global scales.  Areas of the Mediterranean and North Atlantic are also candidates for further research, due to the particular nature of the additional nitrogen deposition in those areas, influenced by different levels of phosphorus and iron.    The report, The Magnitude and Impacts of Anthropogenic Atmospheric Nitrogen Inputs to the Ocean, is

The United States has severely restricted oil and gas exploration off our shores, placing 94 percent of

West Phoenix to Drill in UK and Norway

 Statoil and its partners have contracted the West Phoenix rig for exploration drilling on the U.K. and Norwegian continental shelves from the summer of 2018. The contract is awarded to the two Seadrill companies North Atlantic Drilling UK Ltd. and North Atlantic Norway Ltd. The semi-submersible rig West Phoenix will first drill an exploration well for the Ragnfrid North license on the Norwegian Continental Shelf (NCS), followed by three wells on the U.K. Continental Shelf (UKCS). The rig has been approved by authorities for use both on the NCS and UKCS.   “We needed a high capacity

Malaysia agreed to pay Ocean Infinity up to $70 million if the plane is found within 90 days.   In October 2017, Ocean Infinity deployed six HUGIN vehicles to depths greater than 5,000 meters in the North Atlantic as part of the deepest known commercial dive performed by multiple AUVs simultaneously.

Merian is equipped to conduct sea bottom, water column and atmospheric observations in the Mediterranean, North Atlantic and, thanks to its ice-breaking reinforced hull, the subpolar Norwegian Sea.   Sonardyne said a key factor in the institute’s decision to select Ranger 2 for the Maria S. Merian was the system’s extensive track record in delivering fast, accurate and repeatable positioning

Six AUVs Dive Simultaneously at 5,000+ Meter Depths

A fleet of autonomous underwater vehicles (AUV) recently launched during a survey mission in the North Atlantic have completed the deepest known commercial dive performed by multiple AUVs simultaneously.   The mission, carried out by seafloor monitoring, mapping and exploration firm Ocean Infinity, saw six Kongsberg HUGIN AUVs descend to ocean depths greater than 5,200 meters, reportedly a world’s first for this type of vehicle.   The 6,000m rated vehicles were launched on October 18, each with an independent mission that surpassed water depths of 5,200 meters, collecting MBES data
