Habitat mapping aims to accurately identify and describe the characteristics of different benthic habitats on the seabed, lakes and rivers. In order to achieve this, multidisciplinary data sets based on geological, biological, chemical and oceanographic observations must be gathered together and analyzed. With varied and integrated data sets a comprehensive picture of the underwater habitat can be created. Multibeam Echo Sounder Surveys (MBES) combined with sediment sampling, SVP/Temperature/Salinity observations and underwater photography/video are captured for further processing, analysis and reporting using Geographic Information Systems (GIS). Discovery Marine uses purpose built survey vessels and vessels of opportunity, fitted with MBES, grab/dredge samplers and underwater cameras to gather the data. The final products reveal the diversity and distribution of marine habitats and serve as a useful tool in marine management.
