Greater than the sum of its parts: airborne multi-instrument sea-ice observations
The way sea-ice thickness is currently calculated from satellite altimeter data must be improved. The airborne data presented in our recently published study are only the first step in finding new ways to tackle this issue.
Seven years ago, AWI researchers began constructing a new ocean observatory in Fram Strait, which has gathered data on the physics, chemistry and biology of the ocean round the clock – and in summer and winter alike – ever since.
In order to monitor, understand and even predict changes in Arctic sea-ice cover and especially its thickness, sea-ice thickness time series are indispensable.
Sea-ice Minimum: Prolonged Low Atmospheric Pressure Slows Ice Retreat in the Arctic
In September, the summer sea-ice melting ends in the Arctic. Polar and climate researchers around the globe watch with great interest to see how much sea ice survives the summer.

In turn, the focus of the IceBird summer campaign was on continuing the long-term ice thickness time series at the southern end of the Transpolar Drift.

Moderate Sea-ice Development in the Arctic
The rate of Arctic sea-ice loss over most of July was relatively low, which makes it increasingly unlikely that a new record-low minimum extent will be reached this September.
Arctic sea ice in moderate decline
Following a moderate decline in sea-ice extent in the Artic in June, the month of July began with a short-term phase of more intensive melting.
