Changes in the Arctic Ocean are so profound that the region is entering what amounts to "a new era", according to Norwegian scientists.
A switch from a permanent cover of thick ice will have far-reaching implications, they say.
The Norwegian Polar Institute has been mounting an expedition to the Arctic Ocean during the year's coldest months.
The director of the institute, Jan-Gunnar Wanker, said that measuring what happens in the winter was vital to improving scenarios for future climate change.
"A new era has entered, we are going from old ice to young ice, thinner ice and the climate models used today have not captured this new regime or ice situation.
"So knowing how it is today can improve climate models which again improve the projection for global climate change."
This research effort comes as US scientists have reported that the maximum extent of Arctic sea-ice was recorded at its lowest winter level since satellite records began.
Another biologist taking part in the expedition, Dr Philipp Myass, said it was important to understand how some species might benefit from the ocean having less ice cover - as more sunlight would allow plankton to flourish - while others would suffer.
"We know that the organisms living in the ocean will actually increase because there will be more light available for them to grow.
The expedition is attempting to provide a comprehensive assessment of all key aspects of this part of the Arctic Ocean.
Dr Bologna Itkin has been deploying tracking devices on the ice-floes so that the movement and thinning of the ice can be observed after the expedition ends in June. "We would like to understand how the sea ice cover in this part of the Arctic is behaving in, let's call it, the new climate.
