Mechanisms behind the phenomenon of Arctic amplification are widely discussed. To
contribute to this debate, the (AC) 3 project was established in 2016 (www. ac3-tr. de/). It …

Large freshwater anomalies clearly exist in the Arctic Ocean. For example, liquid freshwater
has accumulated in the Beaufort Gyre in the decade of the 2000s compared to 1980–2000 …

Atmospheric humidity, clouds, precipitation, and evapotranspiration are essential
components of the Arctic climate system. During recent decades, specific humidity and …

We examine the basinwide trends in sea ice circulation and drift speed and highlight the
changes between 1982 and 2009 in connection to regional winds, multiyear sea ice …

We examine the spatial trends in Arctic sea ice drift speed from satellite data and the role of
wind forcing for the winter months of October through May. Between 1992 and 2009, the …

Hydrologic cycle intensification is an expected manifestation of a warming climate. Although
positive trends in several global average quantities have been reported, no previous studies …

A new long-term data record of Fram Strait sea ice area export from 1935 to 2014 is
developed using a combination of satellite radar images and station observations of surface …

Abstract The Fram Strait sea ice volume export 1992–2014 is derived by combining sea ice
thickness from upward looking sonars (ULS) with satellite observations of sea ice drift and …

The evolving knowledge of the Arctic Ocean, its hydrography and its water masses and their
transformations and circulation is reviewed starting with the observations made on Fram …

IPCC climate models underestimate the decrease of the Arctic sea ice extent. The recent
Arctic sea ice decline is also characterized by a rapid thinning and by an increase of sea ice …
