In the Antarctic, the month of February is considered to be high summer in terms of the seasonal decline in sea-ice extent. The extent reaches its lowest point in the year, while in the course of the

“On 8 February 2023, the Antarctic sea-ice extent had reached 2.2 million km² - less than the previous record minimum from 2022. Since the sea-ice melting in the Antarctic will most likely continue in

As our colleagues at the German overwintering station Neumayer III can attest, that doesn’t necessarily mean the weather will get warmer, but at least towards the end of the month they can look forwar

In the course of the past few decades, the sea-ice extent in the Antarctic has been characterised by significant variability – both spatially and chronologically. For example, for the observational pe

If we review the sea-ice extent in the Antarctic over the past few weeks, we can see an exciting trend – and not just in our potential interpretations, but also when we compare the current situation t

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

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 sea-ice extent in the Antarctic is far more variable than in the Arctic. In February, the mean area was 2.52 million km², the second-lowest reading since the advent of satellite measurement and on

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
