Florida Current is the Weakest Its Been in a Century

space and time.”Piecuch, who specializes in coastal and regional sea level change, used a connection between coastal sea level and the strength of near-shore currents to trace the evolution of the Florida Current, a key component of the Gulf Stream. The Gulf Stream flows north along the Southeast Atlantic Coast of the United States and eventually east into the North Atlantic Ocean, carrying heat, salt, momentum and other properties that influence Earth’s climate. Because nearly continuous records of sea level stretch back more than a century along Florida’s Atlantic Coast and in some

NOAA Raises Predicted Number of Tropical Storms to Record High

The U.S. National Oceanic and Atmospheric Administration (NOAA) on Thursday predicted up to 16 more named tropical storms this year, to as many as 25, the highest in the agency's history.The 2020 Atlantic hurricane season, which began on June 1, has already produced nine named tropical storms, two of which reached hurricane strength, including Isaias that lashed the North American Atlantic coast this week."We've never forecast up to 25 named storms, so this is the first time," said Gerry Bell, NOAA’s lead hurricane season forecaster in a conference call with reporters.The

Arctic Melt Leads to Enhanced Storms

Freshwater in the ocean leads to extreme cold patches in the North Atlantic, which has major implications for weather over the surrounding land-masses, a National Oceanography Center (NOC) led research team has found.“Traditionally, it was thought that freshwater leads to a decline in the large-scale ocean overturning circulation, which then results in a cooling of the North Atlantic. Our new study shows that freshwater achieves this cooling much more rapidly and efficiently by triggering atmospheric feedbacks,” said NOC's Marilena Oltmanns, lead author of the study published in the

Salvors Outline Plan to Recover Titanic's Telegraph System

landscape, we have no choice but to move this important expedition."The company also revealed details regarding its telegraph recovery process, including the subsea tooling that will be utilized at the wreck site more than a century after the historic ocean liner's tragic sinking in the North Atlantic.Many have opposed the salvage of the telegraph and other items from the wreck, saying these efforts desecrate the gravesite of the 1,503 passengers and crew who died on the ship's maiden voyage. A long string of litigation and controversy have surrounded the Titanic and its artifacts since the

Ensnared, Endangered Green Sea Turtle Rescued

Best known for housing the third largest barrier reef in the world, Andros Island in the Bahamas boasts a diverse marine population amid pristine waters. It’s perhaps less well known to serve as home to NUWC Division Newport’s Atlantic Undersea Test and Evaluation Center (AUTEC).On July 13, these two worlds collided when a large endangered green sea turtle was found ensnared by fishing lines and nets in AUTEC’s harbor.Mike Beres, a member of the AUTEC Fire and Emergency Services Water Rescue Team, spotted the entangled turtle and noticed that it was struggling to surface for air

"An Epic Mission": Slocum Glider "Silbo" Circumnavigates the Atlantic Ocean

Teledyne Marine reports that its Slocum G2 Glider dubbed Silbo, manufactured by Teledyne Webb Research, completed a 4+-year journey that circumnavigated the Atlantic Ocean in four legs, a first for an autonomous underwater vehicle (AUV).“Born out of Dr. Rick Spinrad’s challenge to build a robot that can cross the Atlantic, these long-endurance oceanic scale basin crossings with little yellow submarines are becoming more and more routine," said Clayton Jones, Senior Director of Technology Teledyne Webb Research. "Along the way, we continue to entrain international and educational

BIOS: North Atlantic Carbon Sink Shrinking Due to Warming

An analysis of North Atlantic Ocean water masses has made it clear that the effects of a warming planet extend beyond biology—they impact the physics of ocean circulation, too. The research, recently published in Nature Climate Change, was conducted by scientists from the University of British Colombia, the Bermuda Institute of Ocean Sciences (BIOS), the French Institute for Ocean Science at the University of Brest, and the University of Southampton.One particular layer in the North Atlantic Ocean, a water mass called the North Atlantic Subtropical Mode Water (STMW), represents around 20% of the

Atlantic Shores Offshore Wind Installs Wind LiDAR in New Jersey

A wind LiDAR (light detection and ranging) instrument has been installed alongside the causeway leading to Rutgers University Marine Field Station in Tuckerton, New Jersey.The fully autonomous sensor platform, owned and operated by Atlantic Shores Offshore Wind, will provide observations of wind profiles up to several hundred feet in a location directly on the land/sea boundary.Atlantic Shores Offshore Wind, a joint venture between Shell and EDF, installed the LiDAR in collaboration with the Rutgers University Center for Ocean Observing Leadership (RUCOOL) and the Rutgers University Marine Field
