Mapping of marine sediments on the Greenland West Coast:contributions of fishers' ecological knowledge
The rapidly changing climate is pushing the Greenland fishing footprint northwards. With bottom fisheries moving into hitherto unmapped areas, large knowledge gaps regarding the environment in which the fishery takes place ensue. Mapping sediment in these areas is a time consuming and expensive task...

The rapidly changing climate is pushing the Greenland fishing footprint northwards. With bottom fisheries moving into hitherto unmapped areas, large knowledge gaps regarding the environment in which the fishery takes place ensue. Mapping sediment in these areas is a time consuming and expensive task. Recognizing that fishers have considerable local ecological knowledge can help bridge this knowledge gap. A workshop including ship masters and factory managers on factory trawlers was conducted in order to understand how their knowledge transpired when mapped. This knowledge was compared to historical data and recent bottom photos to develop a better understanding of the differences and similarities between the methods used. The fishers had a good knowledge of sediment types; further some fishers expressed that the topography has changed over time due to intensive trawling. Even though this fishery is undertaken in a high technology environment on large trawlers, the long-time experience of the fishers can contribute to large scale knowledge of marine landscapes. These results are useful when mapping sediments in the future and can also provide a basis for further investigations of changing topography due to trawling. |
