T he basis of the marine food web in the Arctic, the phytoplankton, responds to heat waves much differently than to constantly elevated temperatures. This has been found by the first targeted ...

Svalbard is the fastest warming place in the world, and even within the Arctic. Leaving as little trace as possible is a ...

As global warming melts more sea ice in the polar regions, the light that enters the ocean is not just increasing in ...

The findings suggest that the capacity of polar oceans to remove carbon from the atmosphere may be reduced as the world ...

“Arctic Station has been here for more than ... Martin Nielsen transfers water samples filled with phytoplankton and zooplankton harvested from his field site, a section of open ocean off ...

A new study has found worrying signs that climate change may be undermining the capacity of Arctic fjords to serve as ...

Arctic fjords, once vital carbon sinks, are losing their ability to store carbon as climate change transforms ecosystems like Kongsfjorden.

Phytoplankton are changing the “physical property of the ... A positive feedback process is already known to occur in the Arctic, as the darker-hued ocean water absorbs more sun than the ...

The disappearance of sea ice in polar regions due to global warming not only increases the amount of light entering the ocean ...

Equipped with fluorescence-detecting AUVs, Mo-Bjørkelund and marine biologist Sanna Majaneva ventured into the Arctic fjords to monitor chlorophyll, the photosynthetic pigment in phytoplankton.

Melting polar ice narrows the light spectrum underwater, favoring blue-tuned algae and disrupting the ocean food web.

At the foundation of Arctic food webs lies phytoplankton—tiny, microscopic heroes of our oceans. These organisms are not just food for fish. They play a pivotal role in carbon cycling and ...
