On the assimilation of ice velocity and concentration data into large-scale sea ice models [PDF]
Data assimilation into sea ice models designed for climate studies has started about 15 years ago. In most of the studies conducted so far, it is assumed that the improvement brought by the assimilation is straightforward.

Unexpectedly high ultrafine aerosol concentrations above East Antarctic sea-ice [PDF]
Abstract. The effect of aerosols on clouds and their radiative properties is one of the largest uncertainties in our understanding of radiative forcing. A recent study has concluded that better characterisation of pristine, natural aerosol processes leads to the largest reduction in these uncertainties.

Machine Learning-Based Image Processing for Ice Concentration during Chukchi and Beaufort Sea Trials
Growing interest in finding the optimal route through the arctic ocean, and sea ice concentration is also emerging as a factor to be considered. In this paper, an algorithm to calculate the sea ice concentration was developed based on the images taken ...

On the measure of sea ice area from sea ice concentration data sets
The measure of sea ice surface variability provides a fundamental information on the climatology of the Arctic region. Sea ice extension is conventionally measured by two parameters, i.e. Sea Ice Extent (SIE) and Sea Ice Area (SIA), both parameters being derived from Sea Ice Concentration (SIC) data sets.

Arctic Sea Ice Concentration Assimilation in an Operational Global 1/10° Ocean Forecast System
To understand the Arctic environment, which is closely related to sea ice and to reduce potential risks, reliable sea ice forecasts are indispensable. A practical, lightweight yet effective assimilation scheme of sea ice concentration based on Optimal ...

Direct determination of the air-sea CO₂ gas transfer velocity in Arctic sea-ice regions [PDF]
The Arctic Ocean is an important sink for atmospheric CO₂. The impact of decreasing sea-ice extent and expanding marginal ice zones on Arctic air-sea CO₂ exchange depends on the rate of gas transfer in the presence of sea ice.

The Arctic sea ice cover of 2016: a year of record-low highs and higher-than-expected lows [PDF]
The Arctic sea ice cover of 2016 was highly noteworthy, as it featured record low monthly sea ice extents at the start of the year but a summer (September) extent that was higher than expected by most seasonal forecasts.

The seasonality of Antarctic sea ice trends [PDF]
Antarctic sea ice is experiencing a weak overall increase in area that is the residual of opposing regional trends. This study considers their seasonal pattern.
