They supply the Filchner-Ronne Ice Shelf with ice from the East and West Antarctic Ice Sheets and are the reason why the largest permanently floating ice shelf in Antarctica measures 1.6 kilometres [...] Filchner-Ronne Ice Shelf from melting,” says AWI oceanographer Dr Tore Hattermann. It’s formed in winter, when the surface water directly in front of the ice shelf freezes and brine from the seaice seeps into [...] alone accounts for ten percent of the global sea level rise. Taken together, the hinterland of the Filchner-Ronne Ice Shelf holds so much ice that the global sea level would rise by twelve metres if this

Seaice is listed as one of the 13 Essential Climate Variables and the aim of the seaice CCI project group is to produce datasets of seaice concentration seaice thickness seaice drift that [...] to the project In the second phase of the seaice CCI, the SeaIce Physics section of AWI is responsible for the production of a merged multi-mission sea-ice thickness time series from data of the ERS-1 [...] the phase 1 of the seaice CCI project. The sea-ice thickness production system will be maintained beyond the lifetime of the project and shall provide publically available sea-ice thickness datasets also

Seaice Remote Sensing Seaice observation systems Seaice plays an important role in [...] Antarctic seaice. In the coastal polynyas, strong winds drive the seaice away from the coast; in these ‘ice factories’ new seaice is constantly formed, while the ice’s point of origin remains ice-free.
