Trends in the time series of annual mean MO dates indicate that MO is occurring earlier in the year for the majority of Arctic sea ice over the 1979–2012 data record

In the absence of leads and away from the ice edge, the original code does not contain information to explicitly derive concentrations of fast, level, consolidated, rafted and

Trend in yearly mean sea ice concentration between 1980 and 2009, shown for (a) the observations (Comiso, 1999), (b) the model simulation without data assimilation (NODA), (c) the

Consequently, the entrainment of the relatively warm water at depth into the mixed layer decreases at high latitudes, the heat content of the water column below 100 m (a depth which

4, we finally compare the magnitude and pacing of past temperature changes reconstructed from deep ice cores to the changes simulated by coupled ocean-atmosphere-sea- ice models

The reconstructions are based on a multilinear regression of forecasted ice concentration, level ice thickness, ridge density, ice speed and an additional factor which is based,

Boundary condi- tions such as sea surface temperatures (SSTs), topography, ice-sheet extent and vegetation are derived from the ones imposed by the Pliocene Model

and pH are already or nearly detectable at the open-ocean time series sites, whereas high variability and autocorrelation in [CO 2 3 − ] may obscure the detection of
