Go to kilden.met.no

Log in with the Mersea userid and password provided by met.no.

The menu in the left-hand panel is used to select what you want:

• List simulations shows a list of the most recent simulations for this user in the main panel. Useful for noting the serial number for simulations of interest.
• Start oildrift simulation brings up the OD3D oil spill model order form in the main panel.
• Start shipdrift simulation brings up the ship drift model order form in the main panel.
• WMS display of drift simulations brings up an embedded Web Mapping Service client in the main panel.

1. Select Start oildrift simulation from the main menu.
2. Fill in the most basic information: the start and ending times of the spill, the position and depth of the source. All other parameters have default values.
3. Fill in other information as necessary:
   • Oil type: Select from the list
   • Simulation duration: The simulation will stop after this period or when the forcing data runs out.
   • email: n/a for Mersea user.
   • Description: Please enter a unique description that is recognizable in the listing.
4. Hit Advanced options button
   • Select the Ocean model
     • met.no is for Norwegian waters
     • default = mercat_o4_glo
     • mfs_16_med = MFS 1/16th degree model of Mediterranean Sea
     • mercat_15_med = Mercator 1/15th degree model of Mediterranean Sea
     • mercat_15_nat = Mercator 1/15th degree model of North Atlantic
     • mercat_04_flo = Mercator 1/4th degree Global model
5. Hit Start button

The service includes a rudimentary viewing facility, which is implemented as an embedded WMS client. It is intended to serve as a backup viewing service for met.no's national clients, who normally use their own dedicated GIS to view data files delivered automatically.

1. Select WMS display of drift simulations from the main menu.
2. Open oildrift listing
3. Select the desired simulation by its serial number
4. Hit Update button

This brings up the WMS client in the main panel. The basic WMS map facilities are available by using the buttons above the map area:

• Zoom in (by clicking once in the map or by drawing out a rectangle)
• Zoom out
• Panning
• Info (n/a)
• Original map section
• Previous view
• Next view
• Update view (same as main menu button)

There is a time selector menu and increment buttons under the main menu.

Base layers include lat-long lines and a toggle for displaying the oil budget text box.

The hirlam20.00 and Nordic4km.00 selections show met.no's latest numerical forecast products for the atmosphere and ocean circulation. Coverage is limited to Europe and the Nordic Seas, respectively. These are in general not the same data that were used to force the drift model. (They will correspond to the forcing data only if met.no was selected as the Ocean model.)

NB! The map projection is tailored to northern Europe and is fixed. The view may be distorted in other areas of the world, for example in the southern hemisphere.
