The Baltic Sea needs an intervention According to scientists, farming is now the biggest source of pollution in the Baltic Sea.
How hurricanes such as Irma and Maria can devastate the Caribbean marine environment Ineffective marine protection rules leave the environment unable to recover when disaster strikes.
Plastic waste from Europe and USA ends up in the Arctic In just a few decades, the Arctic Ocean has become a dumping ground for plastic waste from the USA and Northwest Europe, shows a new study. Over time, plastics from as far away as China could also reach the Arctic.
Come aboard Denmark’s largest research vessel ScienceNordic was invited aboard research vessel Dana to join its regular expedition in the Baltic Sea.
Is a vital pattern of ocean circulation about to shut down? A new study indicates that current climate models overestimate the stability of a vital ocean circulation in the North Atlantic. A breakdown could mean a “chaotic” climate in the Nordics, say scientists.
Marine bacteria are the climate’s wild card How much carbon dioxide will the ocean be able to absorb in the future? A new study of marine bacteria brings us closer to the answer.
World’s fastest fish continues to impress The sailfish is not only the world’s fastest swimmer. A new video reveals that its movements during hunting are the quickest ever seen in a marine animal.
Sperm whale language under scrutiny A new project aims to decode the sperm whale’s communication system using the latest animal-borne acoustic technology.
Copenhagen invaded by research fleet As part of this summer’s science festival ’Science in the City’, a fleet of research ships will be docking in Copenhagen. The public is invited on board to learn about the ins and outs of marine research.
Map outlines global hotpots of bycatch intensity Fishery bycatch poses a great threat to various endangered species, and to ecosystems in general. Scientists have now mapped out the problem.
Metabolism works differently than we thought Kleiber’s law of metabolism, which states that the metabolic rate of an animal scales to the 3/4 power of the mass, has a flaw in it, argues Danish scientist.
Animal origin theory challenged: Early animals needed almost no oxygen The first animals on Earth could get by with much less oxygen than previously thought, new study reveals.
Even tiny oil spills may break Arctic food chain Drilling for oil in the Arctic may have catastrophic consequences, new study suggests.
Huge meltwater reservoir found under Greenland ice A reservoir of meltwater the size of Ireland has been found within Greenland’s ice sheet. The reservoir may increase the melting of the inland ice in the future and provides fundamental new insights into the dynamics of the Greenland ice cap.
How algae slime impacts the climate Algae in the sea ice around the Arctic and the Antarctic convert CO2 into micro-gels. This makes it possible to see whether this cold slime actually counteracts climate change.
Climate change fills polar bears with toxins The melting ice around Greenland has changed the polar bear’s diet. This means that they are being filled with large quantities of environmental poisons, and that forms a threat to the polar bear’s existence.
Greenland icebergs may have triggered the Younger Dryas Just as the last Ice Age was drawing to a close, Greenland icebergs changed the temperature in the Atlantic and triggered a 1,000-year-long extension of the Ice Age.
Microscopic arms race rages on the seabed The ocean floor contains viruses and bacteria locked in a constant struggle for survival. This has a great effect on the carbon cycle in the ocean and thus also affects how much CO2 is released into the atmosphere.
Surprisingly few major Ice Ages in southwest Greenland The waters off southwest Greenland have escaped extremely large and thick ice sheets during most of the Ice Ages, new research reveals.
Singing bowhead whales give new insight into behaviour Of the estimated 12 species of baleen whale, only the song of the humpback and bowhead whale covers both low and high frequency areas. A researcher has looked into this mystery.
Overlooked life on seabed gorges on fish faeces Bacteria are not the only organisms that feed on dead plankton and fish faeces. The so-called ‘archaea’ also play an important – and hitherto overlooked – role in carbon cycling in the seabed.
Sea snakes break rules of evolution Evolutionarily speaking, sea snakes are some pretty weird creatures. They have evolved both large and small heads very quickly and apparently without being separated geographically.
Oceans drive climate change Researchers say that changes in the climate can be traced in the ocean hundreds of years before there is any trace of it in the atmosphere.
Bacteria thrive at the bottom of the Mariana Trench Scientists have found bacteria in one of the world’s most hostile and extreme environments 11 km below sea level.
Live bacteria found deep below the seabed Scientists have found live microbial communities in the earth’s crust deep below the seabed. The discovery may affect our conception of Earth's orbit.
Fish migrate to avoid predators Tagged fish reveal that animals migrate to avoid being eaten by predators.
Warm seas around Greenland may indicate cold European winter Past changes in ocean currents around Greenland coincided with climate change in Northern Europe. The researchers behind the discovery suggest a possible ice-cold winter in Northwestern Europe.
Unusual find saved just in time Paddles dating back to the Ertebølle culture in the Stone Age were recently found in Horsens Fjord, Denmark. They were close to being eaten up by the strong ocean currents.
How Vikings navigated the world With no access to modern navigation instruments, Vikings relied on birds, whales, celestial bodies, chants and rhymes to navigate the seas and discover new land.
Getting Arctic raw materials requires a gentle hand We must be very careful if we want to preserve the Arctic region’s special natural environment and culture while ensuring that the coming raw materials boom doesn’t turn into a disaster.
Mountains are younger than we think A new study has shaved several million years off the age of mountain ranges following new evaluations of fossils and other impressions of ancient sea animals and plants.
Greenland is rising out of the sea Melting ice is currently causing Greenland to rise by 3 cm a year. This rate is accelerating, and if the entire ice sheet is to disappear, the island would rise about one kilometre, new GPS readings reveal.
A warmer Arctic causes fish to move The ice is melting away in the Arctic regions, while precipitation is on the increase. The fresh water forms a lid over essential nutrients in key areas of the Arctic Ocean, and that can change marine life dramatically.
Modern plate tectonics arose 3.2 billion years ago Plate tectonics – geological developments that have given the Earth its current appearance, with oceans, continents, mountains and deep valleys – started 3.2 billion years ago, new research shows.
Bad news for greedy fishermen New research in fish genetics makes it possible to determine the exact origin of any particular fish. This could make life difficult for fishermen who cannot stay away from endangered species.
Carnivorous killer algae found in Danish waters We know that fish eat plankton and plankton eat algae. Think again, says researcher, who has spotted a form of algae so ferocious that can they overpower animals 10,000 times their own size.
Halibut pierced by mysterious ’projectile parasite’ Researchers have discovered a previously unknown parasite that attacks the Greenland halibut by piercing the fillet. The fish almost looks as if it were shot with a rifle.
Winds extend the life of the Arctic icecap The wind plays a much more important role in climate change than previously thought, say Danish researchers, who have mapped the summer ice in the Arctic Ocean going back thousands of years
