The broad area mapped in the Freycinet CMR region as part of CERF Hub studies. Rippled features inshore of, and near the inner CMR boundary are sandy dune systems reflecting historical sand transport in this inshore region. The linear/mottled offshore feature appears to be a relict reef system, described in the more detailed figure above. Pink lines indicate the location of AUV tracks undertaken as part of CERF Hub research documenting the benthic habitats and associated fauna within the Freycinet CMR and adjacent coastal reef systems. These have subsequently been repeat surveyed as part of IMOS (Tasnode) monitoring facilitated by IMAS NERP Hub staff. Red lines indicate the position of towed video runs undertaken as part of CERF Hub (GA/IMAS) validation of multibeam sonar mapping and to describe the broad scale benthic cover of offshore habitats.
