Moorings are autonomous long-term monitoring systems installed at key points in the global ocean circulation system, where they continuously gather data. These instruments for marine research make it

A system used to secure measurement devices and sensors in the ocean for collecting oceanographic data. It typically consists of an anchor weight on the seafloor, a line or cable, buoyancy elements, a

Spending an entire winter researching on an ice floe in the Arctic Ocean was, until now, just a pipe dream for most sea-ice experts. It was always assumed that such an expedition would be too costly,

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

However, the vast area and the extreme weather conditions make it difficult to monitor the snow during Arctic winter. In situ measurements of snow depth on sea ice are rare and mostly obtained in spri

In February, the sea-ice cover in the Arctic remained below the double standard deviation from the long-term average (see Figure 1) and followed a similar progression as in the years 2007 and 2018. In

The dramatic loss of ice in the Arctic is influencing sea-ice transport across the Arctic Ocean. As experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research report in

The thickness of sea ice determines the heat exchange between the ocean and the atmosphere as well as the resistance against the deforming forces of wind and ocean currents. Already a thin layer of se
