Effects of wind, waves, and currents on icebergs and surface floats in the Labrador Sea: a modeling study
Icebergs are major indicators of climate change. In Newfoundland, icebergs attract tourists while simultaneously posing a threat to ships and offshore oil platforms. Research is carried out on a model study of the dynamics of icebergs and surface floats in the Labrador Sea. In this study, the iceber...
