Commissioned by Swedish Agency for Marine and Water Management (SwAM), the Natura2000-area Bratten in Skagerrak will be hydrographic surveyed by AquaBiota in collaboration with Clinton Marine Survey. In conjunction with this, marine survey data is also collected from shallow coastal waters with the purpose of interpreting benthic biotopes. A multibeam echo sounder capable of recording the intensity (or backscatter) data of the reflected return echo will be used. The possibility to use backscatter data together with high density bathymetric data either directly for mapping purposes or indirectly as basis for modelling or interpreting the distribution of benthic vegetation, will be investigated.
The survey data was collected in shallow coastal areas close to Gothenburg and Stockholm. A new co-worker, Trolle Carlsson, has been employed to collect data and work with data analysis. The results will be presented in a report and visualized as a set of maps. The overall goal of the project is to contribute to a more efficient use of regular marine survey data.
