Pour obtenir de plus amples renseignements : http://lois.justice.gc.ca/fr/showtdm/cs/C-42 A fugacity-based methodology is presented to predict the fate of spilled oil in the marine environment. In the proposed methodology, oil weathering processes are coupled with a level IV (dynamic) fugacity-based model. A ｴ ｷ ｯ ｾ ｣ ｯ ｭ ｰ ｡ ｲ ｴ ｭ ･ ｮ system, comprised of water and sediment, is used to explore the fate of oil in a marine environment.During a spill, oil is entrained into the water column due to natural dispersion, which is considered as the primary input source to the water compartment. The direct input to the sediment compartment is assumed negligible. However, the water column acts as a source to the sediment compartment. Unlike the conventional multimedia modelling approach, the impact area is not predefined. Instead, the oil slick spreading process determines the contaminated area growth. Naphthalene is used as a representative oil compound (an indicator) t...

Modeling oil weathering and transport in sea ice

“…Natural dispersion Natural dispersion is a wave dependent process that involves the incorporation of small oil droplets (less than 0.1 mm) in the water column. The product of natural dispersion, unstable and larger oil droplets (greater than 0.1 mm) may coalesce and move to the surface (Nazir et al, 2008). Dispersion speeds up dissolution.…”

“…The small droplets are incorporated in the water column during the natural horizontal dispersion process [18]. These processes are defined as natural vertical dispersion.…”

“…In this way, the model's predictions will help to guide direct observations, and, with the necessary precautions, direct observation will permit the recalculation of prediction data from that point on. Among the various useful works in this field are [4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”
