DOI: 10.1007/s10236-019-01268-0
Abstract: In this study, we investigate how sea ice extent and thickness are affected by additional turbulent mixing from unbroken surface waves. This ‘surface wave mixing’ (SWM) is parameterized by the inclusion of an extra mixing… read more here.

DOI: 10.1007/s13131-016-0886-x
Abstract: Sea ice in the Arctic has been reducing rapidly in the past half century due to global warming. This study analyzes the variations of sea ice extent in the entire Arctic Ocean and its sub… read more here.

DOI: 10.1016/j.jastp.2019.105173
Abstract: Abstract The Arctic seas are mainly located inside the polar vortex under conditions of low temperature. Sea ice extent in these seas in the winter-spring period reaches maximum values with negligible interannual changes. The exception… read more here.

DOI: 10.1017/aog.2023.22
Abstract: Using operational sea-ice maps, we provide first insight into the seasonal evolution of fast ice in the East Siberian Sea for the period between 1999 and 2021. The fast ice season tends to start later… read more here.

DOI: 10.1038/s41467-018-07865-9
Abstract: After nearly three decades of observed increasing trends of Antarctic sea ice extent, in September-October-November 2016, there was a dramatic decrease. Here we document factors that contributed to that decrease. An atmosphere-only model with a… read more here.

DOI: 10.1088/1748-9326/aaf52c
Abstract: The uncertainties in sea ice extent (total area covered by sea ice with concentration >15%) derived from passive microwave sensors are assessed in two ways. Absolute uncertainty (accuracy) is evaluated based on the comparison of… read more here.

DOI: 10.1175/jcli-d-24-0070.1
Abstract: Meridional winds over the seasonal ice zone of the Antarctic have undergone changes and likely contributed to sea ice extent variability in recent decades. In this study, using observations and an eddy-resolving channel model of… read more here.

DOI: 10.33265/polar.v43.9080
Abstract: Accompanying global warming, Antarctic sea-ice extent shows a somewhat increasing trend from 1979 to 2014, followed by an abrupt decrease after 2016. Our previous study examined the change of Antarctic sea-ice extent in austral summer,… read more here.
