WP 10 – Service Activities SA 1. 2 - FRAM: Description The seafloor of selected stations of the HAUSGARTEN observatory is surveyed regularly by a towed Ocean Floor Observation System (OFOS). The vertically facing camera system is used to assess large-scale distribution patterns of larger epibenthic organisms and other objects (e. g. dropstones, garbage) at the deep seafloor.

WP 10 – Service Activities SA 1. 2 - FRAM: Description OFOS images are stored in the PANGAEA repository and analysed on the web interface BIIGLE by experts worldwide. The global access enables quality control of analysed images and enhances scientific exchange between experts for different taxonomic groups. A newly developed GIS based web-viewer developed for this service activity gives also interested amateurs the opportunity to get closer insight to locations of images taken and associated results of organism abundances from the image analysis.
