The icebreaker will have the ability to crack up to 21 feet of ridged ice
, hold 135 crew members and add detached crews, he said.
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.
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. Ice categories are not bounded by the minimum and maximum ice thickness, except the thinnest category that is not allowed to exceed 10 cm in thickness.
The model simulations show a compression and production of the new ridged ice around the damage place during the time of the accident (Fig.
'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.
