Drifter Buoys Aid Seaweed Research

Biologists are using drifter buoys fitted with satellite trackers to understand the dramatic increase of Sargassum seaweed across the North Atlantic.The relatively harmless Sargassum has started washing up in areas including the Caribbean and the southeast U.S. in such huge quantities that it is killing coral, impacting fishing and forcing the closure of beaches. By analyzing the GPS data transmitted from SPOT Trace trackers, researchers from the NIOZ Royal Netherlands Institute for Sea Research, The University of Amsterdam (UvA) and Utrecht University aim to understand where the free-floating,

with them.Nobody has a platform like Alliance.That’s true, and we’re doing our best to keep her in good condition and operating. Based on the world geopolitical situation, and the growing interest in the academic science community, we had aspirations to get the ship back out to the North Atlantic, and the high north, and the Arctic, because the world is changing, and interest in the high north is growing. Not many people have a ship that is ice-capable to get up there, stay up there, and operate in those conditions. Alliance is built as an ice-class ship. We were approached by UNOLS and

First Manned Dive to the Titanic in 14 Years

A groundbreaking expedition in early August led a team of experts and scientists 3,810 meters below the ocean's surface to the Titanic's final resting place at the murky depths of the North Atlantic Ocean.The series of five dives over eight days aboard a high-tech Triton 36,000/2 manned submersible Limiting Factor were the first to carry humans to the historic wreck site in 14 years.Patrick Lahey, Triton Submarines president and Co-Founder, and pilot for three of the five dives, said, “The most fascinating aspect was seeing how the Titanic is being consumed by the ocean and returning to

Further Delay for Vineyard OWP

Wind announced the manufacturing by Sif of 84 monopiles for Vineyard Wind’s offshore wind project (OWP) in Massachusetts USA.The installation of the monopiles is subject to a schedule that includes seasonal restrictions on pile driving activity as a protective measure for the highly endangered North Atlantic Right Whales.Sif’s ability and confidence to meet this schedule was an important consideration in being selected by Vineyard Wind. Sif scheduled the production of these monopiles for the first half of 2020, said the company.The requirement of an additional Environmental Impact Study (EIS)

Offshore Wind: Regulatory “Takes” – Take a Close Look

;s IHA is controlling and attenuating noise and related acoustical repercussions from pile-driving, installing the vertical infrastructure to support wind towers.  These sounds impact numerous species – whales, dolphins, porpoises and seals.  Some of these animals – the North Atlantic right whale, for example – are among the most protected classes of wildlife.For North Atlantic right whales, again, as example, the IHA requires “enhanced clearance measures,” including extended clearance zones, that must be monitored.  If a right whale is detected, pile

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

confident in the data harvested by these machines. I watched real-time as Kraken Robotics’ KATFISH (towed synthetic aperture sonar, SBP, MBES) was hovering 10m above the ocean floor, being towed at 8 knots and capturing high resolution imagery of a never-before-discovered wreck in the North Atlantic. I watched the faces of experienced hydrographers who couldn’t believe the level of automation associated with post-processing and the speed with which the product could be delivered to the client. So, given the operational efficiencies robotics can inherently deliver, one would expect

The vessel is designed to operate world-wide including the geographical coverage area of the IMO Polar Code up till approx. 80o N depending on the ice situation.The capacity of the vessel includes single and double cabins for 34 crew and personnel

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
