Gulf of Mexico ‘Dead Zone’ Smaller than Usual

Scientists have determined that this year’s Gulf of Mexico “dead zone”— an area of low oxygen that can kill fish and marine life — is approximately 2,720 square miles (7,040 square kilometers), an area about the size of Delaware. This summer’s smaller-than-expected dead zone size is the fourth smallest area mapped since 1985 and is smaller than the 5,780 square miles forecast by NOAA in June.The effort to determine the size of the dead zone was led by NOAA-supported scientists at Louisiana State University and the Louisiana Universities Marine Consortium during a

After Florida, more States Press US for Offshore Drilling Exemptions

Donald Trump's efforts to expand oil and gas production offshore. A proposed leasing plan unveiled last week aims to open up all U.S. coasts to drillers over the next five years. Alaska and Maine are the only two U.S. states whose governors have expressed support for the plan.   The governors of Delaware, North Carolina, and South Carolina on Tuesday were seeking meetings with Interior Secretary Ryan Zinke to press their case that drilling would pose significant risks to coastal tourism, while other state representatives issued sharply-worded Tweets.   "Tourism and recreation along the

Cutting Edge Tech Helps Find Lake Huron Shipwrecks

that “the private/public partnerships,” such as that with Thunder Bay National Marine Sanctuary, “help researchers keep up with technology that develops and changes at a very fast pace.”   In the second phase of the project, the sanctuary teamed up with the University of Delaware onboard research vessel R/V Laurentian. For six days, they conducted around-the-clock acoustic mapping of the lake floor, scanning 100-square miles in the heart of the sanctuary. The result of these scans is a huge archive of data that the team must process, review and use to pinpoint the locations

Giant Iceberg Breaks off Antarctica

.   The one trillion tonne iceberg, measuring 5,800 square km, calved away from the Larsen C Ice Shelf in Antarctica sometime between July 10 and 12, said scientists at the University of Swansea and the British Antarctic Survey.   The iceberg, which is roughly the size of the U.S. state of Delaware or the Indonesian island of Bali, has been close to breaking off for a few months.   Throughout the Antarctic winter, scientists monitored the progress of the rift in the ice shelf using the European Space Agency satellites.   "The iceberg is one of the largest recorded and its

And, after soaking in the sea for decades, they are often unrecognizable to the untrained eye, often covered in corals and other sea-life,” said Katy O’Connell, Project Recover’s Executive Director, who is based at the University of Delaware’s College of Earth, Ocean, and Environment. “Our use of advanced technologies, which led to the discovery of the B-25, enables us to accelerate and enhance the discovery and eventual recovery of our missing servicemen.”   Project Recover blends historical and archival data

photographs will be used to identify shipwreck remains, and also to produce photomosaics that may help with identification.   From May 15 through 26, the team will transition to deep-water exploration of the northern area of the sanctuary. Using a wide-sweeping sonar device from the University of Delaware, as much of the lake bottom as possible in this area will be surveyed over 10 days, in 24-hour operations onboard a research vessel from NOAA’s Great Lakes Environmental Research Lab. Expected results of this phase of work will be a number of “targets,” or non-natural items, discovered

Vast Iceberg Poised to Crack off Antarctica

A vast iceberg, expected to be one of the biggest ever recorded with an area almost the size of the U.S. state of Delaware or the Caribbean island state of Trinidad and Tobago, is poised to break off Antarctica. A rift, slowly developing across the Larsen C ice shelf on the Antarctic Peninsula in recent years, expanded abruptly last month, growing by about 18 km (11 miles). It is now more than 80 km long with just 20 km left before it snaps, scientists said. "The Larsen C Ice shelf in Antarctica is primed to shed an area of more than 5,000 square km (1,930 square miles) following further

Search on for Missing Diver in Shark River Inlet

The Coast Guard and local police are searching for a missing diver in the Shark River Inlet in the vicinity of Belmar, New Jersey. Watchstanders at Coast Guard Sector Delaware Bay were notified by the Belmar Police department that a 17-year old free diver was reportedly missing in the Shark River Inlet at around 5 p.m. A Coast Guard 29-foot Response Boat-Small rescue crew was dispatched from Station Shark River and an HH-65 Dolphin helicopter rescue crew was dispatched from Air Station Atlantic City to aid in the search. Also searching are members of the Avon-By-The-Sea and Belmar Police

  The Coast Guard will be enforcing a safety zone within the waters of the Delaware River, from Marcus Hood, Pennsylvania, north to Eddystone, Pennsylvania until March 15, 2016. The safety zone will cover all navigable waters in the Delaware River within 500 yards of vessels and machinery conducting rock blasting, dredging, and rock removal operations. This zone is intended to protect personnel, vessels and the marine environment in these navigable waters while operations are being conducted. Entry into, transiting, or anchoring within the safety zone is prohibited unless authorized by the
