Abstract:

This is a modeling study designed to illustrate the influence of different key parameters (oil properties, oil layer thickness, initial slick size, wind speed, dispersants) on the dispersion process. This is a continuation of a previous study that looked at the influence of oil properties and wind speed on oil slick elongation that is available under GRIIDC Unique Dataset Identifier (UDI) R4.x267.177:0002 (DOI: 10.7266/N7SQ8XFT). This dataset supports the publication: Zeinstra-Helfrich, M., & Murk, A. J. (2019). Effects of Oil Properties and Slick Thickness on Dispersant Field Effectiveness and Oil Fate.

Purpose:

To illustrate the influence of different key parameters on the dispersion process.

Data Parameters and Units:

No [Simulation #]; Uw [Wind speed (m/s)]; Name [Oil Name]; LO [Initial oil slick length (m)]; HO [Initial oil slick thickness (m)]; rhoOil [Oil density (kg/m3)]; muOil [Oil viscosity (Pa.s)]; ift_OW [Oil-Seawater interfacial tension (N/m)]; cdx [calculated model cell length (m)]; cTbw [calculated Breaking wave period (s)]; cWCC [calculated Whitecap coverage (m2/m2)]; czi [calculated Mixing depth (m)]; cDlim [calculated Limiting droplet Diameter (m)]; cFV_Dlim [calculated Volumefraction of oil below Limiting Diameter (-)]; cDmin [ calculated Minimum droplet diameter (m)]; cDmax99 [calculated Maximum diameter of the smallest 99% volume droplets (m)]; cDmax [calculated Maximum droplet diameter]; LT_ThreshV2 [Time integrated length of the slick part with a thickness > 25 micrometers (km.h)]. Note: Light Medium Heavy, LM (Light-Medium), MH (Medium-Heavy). (NAT) and (Chem) refers to whether the oil is naturally or chemically dispersed respectively.

Methods:

The scenarios were performed using the oil spill elongation model as described in GRIIDC dataset R4.x267.177:0002 (https://data.gulfresearchinitiative.org/data/R4.x267.177:0002).
