Currents Not Linked to New England Sea Level

There is no direct link between major North Atlantic ocean currents and sea level along the coast of northeastern United States, according to a recent study by the Woods Hole Oceanographic Institution (WHOI).The study, published last week in the journal Geophysical Research Letters, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC)—a conveyor belt of currents that move warmer waters north and cooler waters south in the Atlantic—and historical records of sea level in coastal New England.“Scientists had previously noticed that if the AMOC is stronger

US Still Processing Atlantic Seismic Permits

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.But Interior's Bureau of Ocean Energy Management, which is responsible for managing energy development on the OCS, continues to review the applications of a half-dozen seismic testing companies awaiting permits to test for oil and gas drilling potential on the Atlantic Ocean floor."BOEM

World Navies: Brazil´s Riachuelo Submarine

Brazil is a country with a coastline over 7,000 km long, bathed to the east by the Atlantic Ocean. Along this coastline and offshore is where the country develops its fisheries activities, maritime trade and the exploitation of a variety of biological and mineral resources. The incredible environmental and financial wealth found in these waters, and under the seabed gave way to the term - Blue Amazon – relating to the Amazon Jungle. The Blue Amazon officially covers an area of 3.5 million square kilometers. However, Brazil is calling on the United Nations to expand its borders to the limits of

the tidal stream project of up to 398 megawatts which lies 2 kilometers from Scotland’s north-east tip. To the north of the site is the uninhabited island of Stroma which creates a natural channel with the mainland to accelerate millions of tonnes of water flowing between the North Sea and the Atlantic Ocean every day.This site was originally identified in 2007 following a global review of tidal resource which concluded that the high flows, medium water depths and proximity to the mainland rendered it a prime location for development.The project is currently the largest planned tidal stream project

France to Test Floating Wind Turbines

electricity from wind.The EU competition regulator said in a statement that the state aid was in line with EU rules as it was proportionate and could help develop a new type of technology to produce renewable energy.Three of the floating wind farms are in the Mediterranean Sea and one in the Atlantic Ocean.The demonstration wind farms will use a particular combination of turbine, floater and cables with a total installed capacity of 24 megawatt each."The objective of the public support is to test these different technological solutions, with the long-term goal to test this technology before

It will be transported and deployed into the ocean depths by the Pressure Drop, a ship retrofitted exclusively for the expedition. The mission includes dives to the Puerto Rico Trench (Atlantic Ocean 8,408 meters), the South Sandwich Trench (Southern Ocean 8,183 meters), the Java Trench (Indian Ocean 7,290 meters), the Mariana Trench/ Challenger Deep (Pacific Ocean 10,925 meters), and the Molloy Deep (Artic Ocean 5,573 meters).Teledyne Bowtech have been supplying lights for Triton vehicles

Argentine Submarine Found After Yearlong Search

The Argentine Navy submarine that went missing a year ago off the country's Atlantic Coast was found by a private company involved in what had been a massive search for the vessel and its 44-member crew, the defense ministry said in a news conference on Saturday.The ARA San Juan submarine was discovered by marine tracking contractor Ocean Infinity, 907 meters (2,975 feet) below the ocean surface. The vessel was found in an underwater canyon with its tail partially "imploded," Argentina's Defense Minister Carlos Aguad said.Given the poor visibility at the site, the ministry said it
