Support system for use when managing ice in an operation area at sea, where a computer system (11) displays a composite view of at least two superpositioned, geographically referenced graphical layers (310, 311, 312; 410, 411; 510, 512; 610, 611, 612, 613; 710, 711), which layers represent geographically distributed information and share the same geographically referenced coordinate system on the display, where at least one first layer represents information which moves with the ice drift over time, and at least one second layer represents geographically stationary information, where a time input means (302; 402; 502; 602; 702) receives a current display time input setting selected along a continuous time scale, and where the computer system updates the displayed layers in response to an input of a current display time, whereby the first layer is translated in accordance with the ice drift between the time stamp and the current display time. |
