Seaspan Shipyards (Seaspan) launched the Canadian Coast Guard’s flagship science vessel, CCGS Naalak Nappaaluk.The fourth ship designed, built and launched by Seaspan under the National Shipbuilding Strategy, the Offshore Oceanographic Science Vessel (OOSV) is a floating laboratory that will serve as the primary oceanographic science platform for Fisheries and Oceans Canada. As a Polar Class 6 vessel, it will be a highly advanced ice capable ship equipped with the latest scientific research systems.

Scientists aboard Britain's high-tech polar research vessel RRS Sir David Attenborough are headed to the Weddell Sea to investigate how carbon dioxide moves and transforms in the Southern Ocean.The ship departed Tuesday from Punta Arenas, Chile for the 30-day scientific expedition.As the carbon in the seawater rises to the surface near Antarctica, it interacts with the atmosphere, ice, and microscopic plants and animals, called phytoplankton and zooplankton, near the ocean surface, before descending to the ocean depths.

Around 6 billion tons of marine sand is being dug up each year in a growing practice that a U.N. agency said is unsustainable and can wipe out local marine life irreversibly.Sand is the most exploited natural resource in the world after water but its extraction for use in industries like construction is only loosely governed, prompting the U.N.

Almost two centuries after Charles Darwin's voyage around the world, environmentalists plan to follow in his footsteps by undertaking a two-year journey across four continents to study endemic wildlife and boost conservation.The group will set sail on board a 105-year-old schooner on Tuesday from the southern English port of Plymouth, from where British naturalist Darwin's own expedition began in 1831, leading him to develop the theory of evolution by natural selection.The 40,000 nautical mile "Darwin200" expedition hopes to anchor in 32 ports, including all the major ports visited by Darwin's

U.S. Coast Guard Cutter Healy (WAGB 20) crew and embarked researchers ventured onto a floe of multi-year ice for the first of three multi-instrument ice stations in the Arctic Ocean Basin late July and early August.As the Healy carefully approached and maintained position alongside an ice floe above 77 degrees north, the crew and a team of scientists, working in cooperation with the Office of Naval Research, (ONR) offloaded a diverse collection of equipment on to the floe carefully…

An emerging technology to fish for lobsters virtually ropeless to prevent whale entanglements is exciting conservationists, but getting a frigid reception from harvesters worried it will drive them out of business and upend their way of life.Injuries to endangered North Atlantic Right Whales ensnared in fishing gear have fueled a prominent campaign by environmental groups to pressure the industry to adopt on-demand equipment that only suspends ropes in the water briefly before traps are pulled from the water.The Monterey Bay Aquarium’s Seafood Watch…

The Arctic Ocean could be ice-free in summer by the 2030s, even if we do a good job of reducing emissions between now and then. That’s the worrying conclusion of a new study in Nature Communications.Predictions of an ice-free Arctic Ocean have a long and complicated history, and the 2030s is sooner than most scientists had thought possible (though it is later than some had wrongly forecast). What we know for sure is the disappearance of sea ice at the top of the world would not only be an emblematic sign of climate breakdown…

In Cape Cod Bay, 10-year-old Pilgrim and her calf skim the water's glassy surface alongside the Shearwater research vessel to feed on tiny crustaceans.The two are among the last surviving 340 or so North Atlantic right whales left migrating along the U.S. East Coast – down from 480 right whales in 2010.The biggest threats they face include being struck by passing ships or getting entangled in ropes used for lobster fishing off the U.S. East Coast - scientists have recorded 98 such injuries or deaths of whales since 2017.Now, the whales face another threat as the U.S.

In 80% of the world, we don’t really know.Across much of the world’s oceans, waves are getting bigger. In the Southern Ocean, where storm-driven swell can propagate halfway across the world to California, the average wave has grown about 20cm in the past 30 years.These changes are part of climate change, and are likely to continue well into the future. If you’re making long-term plans near the sea – like building ships, or constructing flood defenses in coastal cities – you need more detail about how big those waves are going to get.In a study published this week in Science Advances…

The U.S. Coast Guard and Florida’s Department of Environmental Protection (DEP) are monitoring periodic discharges of oil from the Liberty Ship Thomas Heyward, a World War II era vessel sunk in 1977 to serve as an artificial reef approximately six miles southwest of Destin, Fla.Following Hurricane Sally in September 2020, the National Response Center (NRC) began receiving reports of pollution in the vicinity of the artificial reef. Coast Guard personnel conducted preliminary investigations…

A network of acoustic monitoring buoys aims to help protect North Atlantic right whales—one of the world’s most critically endangered species—from ship strikes along the U.S. East Coast.Although North Atlantic right whales are protected under the Endangered Species Act and the Marine Mammal Protection Act, serious threats to their survival abound with only approximately 336 of these great whales remaining on the planet. The installment of the buoys aims to aid in right whale’s survival and will fill a critical gap in monitoring along the East Coast.

PONANT’s new science-focused exploration vessel has started collecting Arctic Ocean data with -4H-JENA engineering’s FerryBox multi-parameter water measurement system on board.The system is now being used to evaluate the role of global warming and glacial meltwater on the rising level of oxygen in the oceans aboard PONANT’s Le Commandant Charcot, the world’s only luxury icebreaker, a hybrid-electric vessel powered by liquified natural gas.A unique concept with minimal environmental impact due to her green energy and propulsion systems…

It was 1914 when the English explorer Sir Ernest Shackleton set sail on his Imperial Trans-Antarctic Expedition aboard a ship called Endurance. It was an ill-fated journey: the ship got trapped in the ice and eventually crushed by pack ice in 1915. It sank to the bottom of Antarctica’s Weddell Sea. (Shackleton and his entire crew survived the ordeal by escaping in smaller boats.)It was difficult to believe that the Endurance might ever be found. The icy Weddell Sea is inhospitable and the wreck lay in more than 3000 metres of water.
