Vertical ocean heat redistribution sustaining sea-ice concentration trends in the Ross Sea
Several processes have been hypothesized to explain the slight overall expansion of Antarcticsea ice over the satellite observation era, including externally forced changes in local winds orin the Southern Ocean’s hydrological cycle, as well as internal climate variability. Here, weshow the critic...

Several processes have been hypothesized to explain the slight overall expansion of Antarcticsea ice over the satellite observation era, including externally forced changes in local winds orin the Southern Ocean’s hydrological cycle, as well as internal climate variability.
