View from the Top produced data every year. We’ve been mapping the months extreme wave and having an iceberg in there at the same time and years for this area based on their data. Some years there is very low. Lesser sea states are more common, particularly are no icebergs at all in a given area, some years there are for ? oaters. The larger icebergs are generally towed and the many. The other hazard is calving. You get small icebergs and ? oating systems can disconnect and move off location. With bergy bits, accelerated by waves. (A bergy bit is glacier ice, 1 ? xed structures, you have to worry about bigger bergs. While to 5 meters above sea level and 5 to 15 meters long.) they are not affected by sea states as much as small ones, they Wave-induced motions increase the kinetic energy might be the biggest hazard in this case.

Waves can accelerate an ice piece, and there’s a decreased chance of detecting it. The joint probability of having a very I’d say C-CORE is the leader. They have a very good
