Resource exploration continues in the region, and proposed mines in mainland Nunavut could lead to even greater year-round ship traffic, meaning a likely increase in the probability that ships will encounter hazardous ice conditions such as pressured and ridged ice.
Examples of highly ridged ice and relatively level ice can be seen in Figure 2.
Ships traveling through the Hudson Strait during the winter months have often encountered ridged ice and pressure.
Different words describe pack ice, melting ice, ridged ice and rime, ice that stretches across vast expanses, and ice in all its forms on the surface of water.
In particular, we aim for a detection of MYI floes in a area composed mostly first-year ice from synthetic aperture radar (SAR), heavily ridged ice regions from SAR, the thickest ice from radar altimeter (RA) thickness profiles, regional anomalies of thick or thin ice via passive microwave (PMW) data, sea ice areas vulnerable for the wave action, detection of early/late melting season and improving capabilities to forecast seasonal sea ice extremes.
Pack ice in the gulf tends to raft and ridge frequently-the proportion of ridged ice usually rises to 25% in February (SMHI 1982).
Deformed ice is divided into separate categories of rafted and ridged ice.
Ridged ice covers large offshore areas of the gulf and ice thickens towards its eastern part.
The deformed ice is separated into two ice thickness categories, one for rafted ice and the other one for the ridged ice.
The model simulations show a compression and production of the new ridged ice around the damage place during the time of the accident (Fig.
The mean total ice thickness in the region was over 70 cm, whereas the mean ridged ice fraction was 60-80%.
You've got more thick ice, more ridged ice, and at the same time you will get more ice extent because the ice just survives longer,' said Zhang.
