Tiny but globally significant – What algae beneath sea ice reveal about climate and food webs

Marcel Schütz

A new study led by PhD candidate Megan Lenss from Norway’s iC3 Polar Research Hub places previously overlooked organisms at the center of scientific attention

Antarctica’s sea ice is changing, and so is a vital part of the marine food web that lives within it

Polar Journal AG Team

As Antarctic sea ice forms later and thinner, a hidden ecosystem is shifting: microalgal diversity is declining, disrupting a key food source for marine life.

Elephant seals as helpers in researching fish populations

Julia Hager

Studying the ecologically and economically important fish populations in the ocean's twilight zone presents enormous challenges. However, in the North Pacific, northern elephant seals now appear to make this task significantly easier.

Krill play a key role in carbon storage – plastic disrupts this process

Julia Hager

Plastic pollution in the Southern Ocean may hinder the efficient transport of carbon bound by Antarctic krill to the deep ocean, with implications for the global carbon cycle and thus for global warming.

Like a wasp waist: the marine food web of the Falkland Islands

Julia Hager

The marine food web around the Falkland Islands is controlled by only a few species.

The winter survival strategies of juvenile Antarctic krill.

Julia Hager

Juvenile krill employs amazing strategies to survive the long, cold winter under the sea ice.

High mercury concentration in meltwater from Greenland's glaciers

Julia Hager

According to a recent study, the strong temperature increase in the Arctic leads to extremely high mercury concentrations in meltwater rivers in Greenland.

Sea otters vanish followed by an ecosystem collapse

Julia Hager

The delicate underwater ecology of the Aleutian Islands in Alaska suffers twofold from the decline of the otters in the face of climate change.

Fur seal whiskers provide insights into the food web

Julia Hager

Australian researchers used whiskers and blood samples from Antarctic fur seals to reconstruct their diet and make conclusions about the dynamics of the Southern Ocean food web.

Microplastic in Antarctic soil animals

Julia Hager

For the first time, researchers were able to demonstrate how plastic particles enter the Antarctic food web.
