On 11 September the sea-ice extent (sea-ice concentration > 15 %) was 3.94 million km² (see Figure 1) and on 3 September 2019 it had already decreased to 3.82 million km², the lowest level so far this
Sea-ice conditions in the first half of October 2019 In mid-September, the autumnal sea-ice formation process began in the western Arctic Ocean (see Figure 1). Sea ice extent is with 4.97 Mio. km² far
According to analyses from the University of Bremen’s Institute of Environmental Physics, the mean sea-ice extent in the Arctic this October was only 5.44 million km², which is more than 443,000 km² b
21 December marks the astronomical first day of winter in the Northern Hemisphere and first day of winter in the Southern Hemisphere, referred to as the winter solstice and summer solstice, respective
After the summer minimum in the Antarctic, sea-ice growth rebounding sluggishly On 31 March 2024, the Antarctic sea-ice extent, at 4.52 million square kilometres, reached its maximum for the month of
Development in the Arctic The slight upward trend following the Arctic minimum continued in early 2024; although the sea-ice extent was below the mean value for the years 1981 – 2010 at the beginning
The annual development of the sea-ice extent is one of the most important parameters for describing the seasonal progression of sea-ice development. It is particularly relevant when combined and compa
Visualising scientific data is no mean feat and certain technical requirements must be met. At the same time, when the goal is to convey information to a given target group in a clear and appealing wa
This year, the minimum Arctic sea-ice extent, at 4.33 million km², was most probably reached on 15 September (Figure 1), putting it at 7 th place in the sequence of minima since 1979. The sea ice had
The sea ice in the polar regions is an important indicator for global climate change, as the two regions are essentially our planet’s early warning system. The loss of sea ice is a direct effect of gl
