IUCN (International Union for Conservation of Nature) slår i en ny rapport fast att om vi vill rädda hajar, rockor och havsmöss i vårt hav, måste vi få bukt med överfisket och bifångsterna.

In this video we explore the world of whale and dolphin communication. They use sound in extraordinary ways — from the powerful clicks of sperm whales, reaching over 230 decibels, to the unique, individual whistles of bottlenose dolphins. While many of these sounds are used for echolocation, helping them navigate and hunt, some researchers believe they could also serve as a form of complex language.

Old boat engines that are environmental culprits must be removed. This is stated in a new action programme from the Swedish Agency for Marine and Water Management. Another new point concerns antifouling paints with biocides, which are estimated to do particularly great damage in the salt-poor waters of the Baltic Sea

The Center Party wants to invest SEK 725 million over the next three years to reduce eutrophication of the Baltic Sea

"We know approximately how much the fish poop, how much carbon it contains and also how quickly the feces reach the bottom. Against this background, we therefore wanted to investigate how much impact commercial fishing has on carbon storage in the ocean", says Daniele Bianchi from the University of California

The African penguin is being starved to extinction. Commercial fishing has reduced fish stocks around the only remaining African Penguin colonies to such an extent that the birds cannot find enough fish to eat during their breeding season. Southern African Foundation for the Conservation of Coastal Birds, SANCOB is taking the South African government to court to try and force them to expand no-take zones around the colonies as part of their campaign to save the species.

The aggressive bull shark has increased sharply in a coastal area in the United States. Scientists link it to rising water temperatures – and predict more shark-human interactions as the planet warms.

The Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organisation (UNESCO) has published this year's State of the Ocean Report, which describes the state of the ocean and marine life.

For an extended period, the cod population in the Baltic Sea has been facing severe challenges. Overfishing and environmental issues have taken a toll on their well-being, causing a decline in their health. Consequently, many of them have become thin, emaciated, and susceptible to diseases. However, a pertinent question arises: What happens when wild cod are given the opportunity to recuperate?

The island paradise of Raja Ampat is one of the last outposts of the Indonesian archipelago. A remote group of islands with lush white beaches surrounded by turquoise waters, a unique place characterised by its biodiversity. But even here, nature is not left alone by the human footprint. The increasing amount of rubbish in the water is becoming a growing problem with multiple bottoms.

China has the world’s largest distant-water fishing fleet, catching billions of pounds of seafood annually, the biggest portion of it squid.

It blows up to a storm over the Atlantic. Record-warm ocean waters and a natural weather phenomenon have experts warning of what could be one of the worst hurricane seasons on record.

Three quarters of the world's industrial fishing vessels are "dark", they are not publicly tracked. This is shown by a new study, published in Nature, which with the help of space technology and AI managed to create the first global map of how we use the ocean. The fishing vessels dominate and most of them do it stealthily. The study shows that 75% of fishing vessels neglect to broadcast their positions, which may indicate illegal fishing.

We explore the plastic pollution crisis in the Philippines, focusing on the widespread use of disposable plastic sachets. These sachets are difficult to recycle and significantly contribute to environmental degradation, especially in rivers and oceans. Research indicates that the river flowing through Manila may account for up to 6% of all plastics entering the oceans.

E-DNA has been used to, among other things, track the spread of the coronavirus in our wastewater – now researchers are testing the method on pike

The sound on the beach is deafening. Using the word cacophony feels enticing, but on reflection, symphony feels like the right choice of words. On Stora Karlsö, the birds live in symbiosis with each other

Every year, large amounts of fishing equipment are lost in the sea. In many cases, the equipment continues to fish without anyone taking care of the catch – so-called ghost fishing. On the West Coast, lobster tins pose the big problem and it is estimated that thousands are lost annually. Along both the west and east coasts, however, several projects are underway aimed at cleaning the ocean from these death traps

Earth's climate is close to several tipping points where development becomes irreversible, with enormous consequences for our living conditions. Now researchers are pinning their hopes on a different kind of threshold point – which can make us quickly change behavior

Many of the world's coastal cities are not at all prepared to cope with changing weather conditions. This is stated by an international research group that wants to see climate adaptation gain momentum. Another research group warns of more powerful hurricanes across the Atlantic.
