Laboratory study on coprecipitation of phosphate with ikaite in sea ice [PDF]
, 2014 Ikaite (CaCO3 6H2O) has recently been discovered in sea ice, providing first direct evidence of CaCO3 precipitation in sea ice. However, the impact of ikaite precipitation on phosphate (PO4) concentration has not been considered so far.

Spatial Patterns, Mechanisms, and Predictability of Barents Sea Ice Change [PDF]
, 2022 Recent Arctic winter sea ice loss has been most pronounced in the Barents Sea. Here we explore the spatial structure of Barents Sea ice change as observed over the last 40 years.

The Arctic sea ice cover of 2016: a year of record-low highs and higher-than-expected lows [PDF]
The Cryosphere, 2018 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.

Sea ice inertial oscillations in the Arctic Basin [PDF]
, 2012 International audienceAn original method to quantify the amplitude of inertial motion of oceanic and ice drifters, through the introduction of a non-dimensional parameter M defined from a spectral analysis, is presented.

A machine learning model of Arctic sea ice motions [PDF]
arXiv, 2021 Sea ice motions play an important role in the polar climate system by transporting pollutants, heat, water and salt as well as changing the ice cover. Numerous physics-based models have been constructed to represent the sea ice dynamical interaction with the atmosphere and ocean.

Remote Sensing, 2014 Extensive sea ice over Arctic regions is largely involved in heat, moisture, and momentum exchanges between the atmosphere and ocean. Some previous studies have been conducted to develop statistical models for the status of Arctic sea ice and showed ...

Improved simulation of Antarctic sea ice due to the radiative effects of falling snow [PDF]
, 2017 Southern Ocean sea-ice cover exerts critical control on local albedo and Antarctic precipitation, but simulated Antarctic sea-ice concentration commonly disagrees with observations.

Erroneous sea-ice concentration retrieval in the East Antarctic [PDF]
Annals of Glaciology, 2018 ABSTRACTLarge discrepancies have been observed between satellite-derived sea-ice concentrations(IC) from passive microwave remote sensing and those derived from optical images at several locations in the East Antarctic, between February and April 2014. These artefacts, that resemble polynyas in the IC maps, appear in areas where optical satellite data ...

When Will Arctic Sea Ice Disappear? Projections of Area, Extent, Thickness, and Volume [PDF]
arXiv, 2022 Rapidly diminishing Arctic summer sea ice is a strong signal of the pace of global climate change. We provide point, interval, and density forecasts for four measures of Arctic sea ice: area, extent, thickness, and volume. Importantly, we enforce the joint constraint that these measures must simultaneously arrive at an ice-free Arctic.

Impact of the ice thickness distribution discretization on the sea ice concentration variability in the NEMO3.6-LIM3 global ocean–sea ice model [PDF]
Geoscientific Model Development, 2019 Abstract. This study assesses the impact of different sea ice thickness distribution (ITD) configurations on the sea ice concentration (SIC) variability in ocean-standalone NEMO3.6-LIM3 simulations. Three ITD configurations with different numbers of sea ice thickness categories and boundaries are evaluated against three different satellite products ...
