Arctic Ocean Science Platform Over Sea Ice
font style='font-size:12px;'>
2015/7/17
Physical sampling of sea ice, the water mass, and subbottom geology in the Arctic Ocean is carried out from icebreakers or temporary ice camps deployed and supported by aircraft. Here, we consider an ...

A few decades ago, Antarctic ice sheets were expected to grow as the
atmosphere warmed and increasing poleward moisture transport added snowfall
to regions that would remain below freezing year-ro...

2014/4/2
The timing of ice-out in high latitudes is a fundamental threshold for lake ecosystems and an indicator of
climate change. In lake-rich regions, the loss of ice cover also plays a key role in landsca...

2009/10/21
The structure and optics of ice and snow overlying bodies of water were studied in the
years 2000–2003. The data were collected in the northern temperate region (nine Estonian and
Finnish lakes...

Seasonal Change Sea-Ice Model
font style='font-size:12px;'>
2009/3/7
A three-dimensional thermodynamical model of sea ice has been developed which is capable of simulating seasonal changes over the arctic and antarctic regions. The model is patterned after the earlier ...

Thermodynamic Growth Numerical Investigations of Climate Sea Ice
font style='font-size:12px;'>
2009/3/7
A model is presented whereby the thickness and extent of sea ice may be predicted in climate simulations. A basic one-dimensional diffusion process is taken to act in the ice, with modifications due t...
