Air-ice carbon pathways inferred from a sea ice tank experiment
Elementa: Science of the Anthropocene, 2016 Given rapid sea ice changes in the Arctic Ocean in the context of climate warming, better constraints on the role of sea ice in CO2 cycling are needed to assess the capacity of polar oceans to buffer the rise of atmospheric CO2 concentration. Air-ice CO2

Snow-ice contribution to the structure of sea ice in the Amundsen Sea, Antarctica
Annals of Glaciology, 2020 The widespread occurrence of snow-ice formation on the pack ice plays a critical role in the mass balance of Antarctic sea ice. The stable isotope composition, ice texture and salinity of eight ice cores, obtained from the Amundsen Sea during the Oden ...

Initial snow-ice formation on a laboratory scale
Annals of Glaciology, 2023 Snow ice (SI) forms from freezing wet snow, known as slush, and contributes to the thickness of level and brash ice. However, the mechanism of snow-slush-snow ice transformation has not been extensively investigated to date, despite the difference in the

The dynamics of unstable waves in sea ice
Scientific Reports, 2023 Wave and sea ice properties in the Arctic and Southern Oceans are linked by feedback mechanisms, therefore the understanding of wave propagation in these regions is essential to model this key component of the Earth climate system.

The sensitivity of sea-ice brine fraction to the freezing temperature and orientation
Annals of GlaciologyThe changing conditions in which sea ice forms and exists are likely to affect the properties of sea ice itself, and potential climate feedbacks need to be identified and understood to improve future projections.

Phenotypic plasticity of southern ocean diatoms: key to success in the sea ice habitat? [PDF]
PLoS ONE, 2013 Diatoms are the primary source of nutrition and energy for the Southern Ocean ecosystem. Microalgae, including diatoms, synthesise biological macromolecules such as lipids, proteins and carbohydrates for growth, reproduction and acclimation to prevailing

IODP Expedition 325: Great Barrier Reefs Reveals Past Sea-Level, Climate and Environmental Changes Since the Last Ice Age [PDF]
Scientific Drilling, 2011 The timing and courses of deglaciations are key components in understanding the global climate system. Cyclic changes in global climate have occurred, with growth and decay of high latitude ice sheets, for the last two million years.

Insights into oxygen transport and net community production in sea ice from oxygen, nitrogen and argon concentrations [PDF]
Biogeosciences, 2014 We present and compare the dynamics (i.e., changes in standing stocks, saturation levels and concentrations) of O2, Ar and N2 in landfast sea ice, collected in Barrow (Alaska), from February through June 2009.
