The Seeding Options | Group Options frame is shown in Figure 1 below for oil spill. As there are many types of oils and different weathering of these types of oils, a group should be defined which has its own chemical property and volume per seed. When Oil Spill Options are enabled all the seeding options defined will apply to the group currently selected for the Group ID and the Properties button for oil spill will be enabled. In addition, below the Properties button, the volume and mass of oil for that group are displayed.

Figure 1 LPT: Seeding Utility by Group.
Clicking the Properties button will display the oil parameters settings as shown in Figure 2 . Each oil group requires a separate ID along with the density and the volume of oil per drifter. Biodegradation and vapor pressure are entered to provide the properties for all the drifters in the current group. Though temperature is optional, it is recommended that heat transfer be included, as the oil spill evaporation process depends on the temperature of the ambient environment. Winds also impact evaporation and it is expected that with any realistic oil spill model, winds will be included.
