Update for New report

Spill ID:

The incident details will appear here once you select a spill in the map or in the table view.

Map and data layers in the map can be switched on and off using the overlay control at the right side.

The spill causes are either Oil company (in black) if they were considered responsible, Third party (in red) otherwise.

Pending visit spills (purple) are those for which a Joint Inspection Visit (JIV) is yet to be carried out, except cases where it is not possible to reach the spill site.

Each circle's area corresponds to the quantity spilled, one pixel per barrel except small ones which are drawn with a minimum radius of 4 pixels.

Unquantified spills have a dashed border, and are those for which the report does not include an estimated quantity of barrels spilled.

Reports without geographical coordinates are not shown in the map, but are available at the table view. This is indicated with the map legend "Located x of y spills".

Spills that were at least partially cleaned are shown as Cleaned up, in grey.

New spills (orange speech bubble) are new reports that are being clarified
