Regatta sailor Boris Herrmann has installed a mini-laboratory on his high-tech yacht "Seaexplorer" - and transmits information to ocean researchers during his races. The data helps to improve climate models.

More and more animals and plants are threatened with extinction. With their fine sense of smell, species-tracking dogs can often track down these endangered species better than technology or humans.

As logistics coordinator of the largest Arctic expedition ever, Verena Mohaupt ensured smooth and safe operations on board the "Polarstern". She enjoyed seeing how her concepts worked out in practice - even though the Corona pandemic threw many plans out of kilter. 

Since October 2020, Katja Matthes has been head of the Kiel Research Center GEOMAR. The sports enthusiast and climate scientist is convinced that the oceans can contribute much more to climate protection. In a pinch, they need a little help.

Behind the success of MOSAiC is a perfectly coordinated planning team. Curious polar bears were the least of the problems during the expedition - it was the Corona pandemic that caused the planners sleepless nights.

He experienced the polar night, had to reschedule an entire expedition and was frozen to the end of the world in the middle of the Corona pandemic. Why Markus Rex has little fear and why he is now calling for decisions on climate protection.

The Potsdam geotechnologist Hannes Hofmann ensures that more electricity can be generated from geothermal boreholes in Iceland. At the same time, he is keeping in mind that the boreholes do not pose any risk of earthquakes.

Climate change also poses major challenges for agriculture. In an interview, biologist Ulrich Schurr reveals what needs to be done, what role artificial intelligence plays in this, and how a new research cooperation with researchers from Israel could also help German farmers.

It was the grand finale of the MOSAiC expedition: After one year the research vessel "Polarstern" returned to Bremerhaven. About 500 people from 20 nations were on board in several stages. Frozen in a floe, they drifted around the North Pole.
