The record-breaking journey began when Stefanie Arndt and Leonard Rossmann from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven placed the buoy on the

The sea-ice extent in the Arctic is broadly considered to be an important indicator for the on-going climate change. This year, the month of October, in which the freezing season begins and new ice is

In April 2017, sea-ice physicist Stefanie Arndt from the Alfred Wegener Institute in Bremerhaven proved once again that necessity is the mother of invention: she and her colleagues were wondering how

The sea-ice extent in the Antarctic is slowly but surely nearing its seasonal minimum, which we expect to see roughly a month from now. With 3.36 million km² of pack ice covering the Antarctic contine

The air temperature, humidity, pressure and wind fields determine the circulation, and with it, the inflow of warm air masses from the temperate latitudes. In addition, the ocean temperature is the mo

These include data on sea-ice formation and dynamics in the Antarctic pack-ice belt. When the Federal Republic of Germany became a signing member of the Antarctic Treaty in 1979 and established the Ge

Not until the end of the month did the sea-ice extent substantially decline, dropping below two standard deviations from the average for the period 1981 – 2010. At the same time, the summer solstice w

While the Arctic sea ice continues to decline, a glance at the Southern Ocean reveals a different picture: in recent years and decades, the sea-ice extent has increased slightly – albeit with clearly

The Arctic: Pronounced high- and low-pressure systems intensified the Beaufort Gyre and accelerated sea-ice export in Fram Strait. In the Laptev Sea, the combination of these factors led to an early b

Markedly low levels of winter sea ice in the Barents Sea and Bering Sea; Arctic is losing substantial amounts of older sea ice through Fram Strait In Svalbard, meteorologists observe rapid temperature
