Drift ice material

2011
This chapter presents the material structure of sea ice from local scale to large scale. Ice floes form granular drift ice fields, for which continuum approximations are used when the scale of interest is much larger than the floe size. These fields are char- acterized by their ice type, ice compactness, floe size and shape, and ice thickness, as shown

Equation of drift ice motion

2011
The law of conservation of momentum, or the equation of motion, is derived for drift ice from Newton's second law for a continuum in Section 5.1. By integrating through the thickness of ice, the two-dimensional equations can be obtained.

Patterns of sea ice drift and polar bear (Ursus maritimus) movement in Hudson Bay

, 2020
Sea ice habitats are highly dynamic, and ice drift may affect the energy expenditure of travelling animals. Several studies in the high Arctic have reported increased ice drift speeds, and consequently, polar bears Ursus maritimus in these areas expended

Climate of the drift‐ice zone

Polar Geography, 1977
Abstract The article discusses climatic characteristics in the drift‐ice zone, including circulation conditions, radiation regime, temperature and pressure fields, cloud micro‐structure and the climate of the free atmosphere. The significance of climatic studies in this region is emphasized in connection with plans for resource development and ...

Simulation and forecasting of ice drift as a tool for autonomous under ice operations [PDF]

2020 IEEE/OES Autonomous Underwater Vehicles Symposium (AUV)(50043), 2020
This paper explores the use of model based ensemble forecasting and Gaussian process (GP) modelling of ice drift as a risk reducing and situational awareness tool for supporting under ice operations with autonomous underwater vehicles (AUVs). Ice tethered navigation buoys will be used to guide the vehicle under the ice and back to the ice-relative ...
