Bowhead whales are ingesting toxins driven by warming in Arctic, study finds

(Photo provided by the National Oceanic and Atmospheric Administration)A long-term study of bowhead whales in Alaska published this week points to a direct correlation between ocean warming and threats to the Arctic food web. An example of a fecal sample from a subsistence-harvested bowhead whale, part of a long-term study of ocean conditions, algal…
Amplified warming accelerates deoxygenation in the Arctic Ocean
Overall ocean health depends critically on dissolved oxygen, which is increasingly impacted by global warming. The Arctic and subarctic regions are experiencing exceptionally rapid warming, known as Arctic amplification, yet its impact on oceanic oxygen remains poorly understood. Here we show that inflowing Atlantic Water (AW) drives deoxygenation in the upper eastern Arctic Ocean and the intermediate layers of the western Arctic Ocean at rates …
Another natural space at the mercy of climate change and another negative effect on ecosystems and human beings, in this case on the coast of the Arctic marine environment where harmful algae that are toxic due to their harmful effects have started to bloom. To this conclusion researchers from the NOAA Fisheries in Seattle, United States, have come to the conclusion in a study with which they discovered that there was a direct reality between th…

Augsburger AllgemeineSometimes researchers' work can consist of freezing cetaceans of whales – and analyzing them closely.In this case, the faeces tell of a worsening dangerThe faeces of Greenland whales can be seen as a result of climate change in the Arctic Ocean – and the dangers associated with it for animals and humans.By increasing sea temperatures, certain algae species thrive better, which form toxic metabolic products (algentoxins) – and thus pollute marine…
