Coast and Fjord
Ordinary ocean maps provide limited information about ocean depths, and completely lack information about the submarine landscape, sediments, currents and other environmental conditions. In order to optimize the value creation, in a sustainable way, we need more knowledge. A good knowledge base may help minimize conflicts related to marine area use.
Several NGU projects have provided detailed Marine maps from areas on the coast. The most detailed maps so far is prepared in Fosnes municipality in Nord-Trøndelag County, in South Troms and in the Oslo fjord. The maps are of great help in the municipalities 'management' of their marine areas.
As an example, municipal planners can directly access data from detailed digital maps that contain information regarding anchoring conditions, dredgability and identify oxygen-poor areas. Hence, decisions as to where a fish farms can be placed can take into consideration factors that will allow for optimal fish health, high productivity, and secure anchoring.
