A study forecasts up to 872 billion Euros in economic losses for the EU and UK due to sea level rises by 2100, emphasizing the need for targeted investments and region-specific economic policies. Credit: SciTechDaily.comSea level rises could cost the EU and UK up to 872 billion Euros by 2100, indicating a need for region-specific economic strategies.Damage caused by sea level rises could cost the EU and UK economies up to 872 billion Euros in total by the end of the century, according to a modeling study published today…

Scientists found four new octopus species, unveiling new insights into deep-sea biodiversity and emphasizing the need for international collaboration in marine conservation. On Tuesday (January 16), the Schmidt Ocean Institute said that a team of scientists had made a groundbreaking discovery in the waters off Costa Rica.So far, only one of the new species of deep-sea octopus has been named, CBS News reported.Nevertheless, all four new species, found in a 100-square-mile-sized area near Costa Rica, are currently in the…

Key organisms in the Southern Ocean and 21st century ocean acidification in Marine Protected Areas. Credit: Nature Communications (2024). DOI: 10.1038/s41467-023-44438-x The acidity of Antarctica's coastal waters could double by the end of the century, threatening whales, penguins and hundreds of other species that inhabit the Southern Ocean, according to new research from the Univeristy of Colorado Boulder.…

Satellite image of Cabo Frio’s diverse coastline captured on September 16, 2023, by the Operational Land Imager-2 on Landsat 9.People have long noticed that the waters around Cabo Frio are unusually cool.When European explorers first surveyed the coastline of what is now the state of Rio de Janeiro in the early 1500s, they encountered white sands, turquoise waters, shallow lagoons, and lush green mountains rising from the sea. The waters in one area, however, were unusually cool—so much so that the promontory in…

The Arctic Ocean may be ground zero for climate change. According to a study published in Geophysical Research Letters, runoff from the Mackenzie River in Canada is causing the ocean to release more carbon than it releases, and as the ocean warms, the Arctic carbon emissions will only continue to rise.Scientists estimate that the Arctic absorbs as much as 180 million metric tons of carbon annually. This is more than three times the carbon that New York City emits. As such, the Arctic is one of the most important…

Warming ocean temperatures caused by climate change will provide favourable conditions for Atlantic halibut, according to a new study, although what happens to their prey is uncertain.A paper published in the journal FACETS links an exponential increase in Atlantic Canadian landings over the past decade to warming ocean temperatures and predicts that trend is likely to continue under low- and high-warming scenarios in coming decades."Under both of those scenarios, we see similar trends. Even in the higher emission…

It's been estimated that the…

Over 40 years, the Bermuda Atlantic Time-series Study has documented significant warming, increased salinity, reduced oxygen, and higher acidity in the North Atlantic Ocean, highlighting the critical changes occurring in global marine environments. Data spanning 40 years shows changes in the subtropical North Atlantic Ocean near the island of Bermuda, including warming by 1°C. Oceans are constantly changing. These changes don’t only affect marine life but also have wide-reaching consequences for land dwellers. To…

People love to hang out around water, especially on hot summer days. And, for those who aren't near the ocean, Australia is blessed with beautiful inland waterways. In New South Wales, the government wants to increase access to these "blue" natural environments, especially for people living far from the coast. One of these swimming sites is Penrith Beach, which has just opened to the public for the summer. This new site in the heart…

July 9, 2023 The little-known ginkgo-toothed beaked whale has a wider range than previously understood, extending to the chilly waters of the North Pacific. Cetaceans, widely known as fully aquatic animals, encompass whales, dolphins, and porpoises. This group includes over 90 existing species, categorized into baleen whales (Mysticeti) and toothed whales (Odontoceti).…
