A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk. The research led by scientists

We know little about the fish stocks in the central Arctic Ocean, and what we know about the local ecosystem is insufficient to ensure sustainable management. In response, in June 2021 the Agreement to [...] to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean – which includes a moratorium on fishing in the region – entered into force. The European Union and nine other countries signed the

Over the past 200 years, our planet’s oceans have absorbed more than a quarter of all anthropogenic carbon dioxide from the atmosphere. As a result, their acidity has increased by nearly 30 percent their [...] recently demonstrated. If this comes to pass, it could have far-reaching consequences for life in the ocean, as they report in the journal Nature.
