Modelling the Oceanic Advection of Pollutants Spilt Along with the Northwest Passage Atmos. Ocean (IF 1.2) Pub Date : 2022-05-09 Ran Tao, Paul G. Myers
ABSTRACT The Arctic sea ice is dramatically retreating in concentration, thickness, and duration. The larger and longer-lasting periods of open water will likely lead to increase trans-Arctic ship traffic, which then increases the risk of accidents and of pollutant spills. In this study, we focus on the potential oceanic circulation pathways of pollutants that may be spilt along with the Northwest
