This is a review of seabed imaging survey methods and their application in New Zealand, focusing on the deep sea and covering the fields of image acquisition, data extraction from imagery, and data management. The potential of new technologies and analysis methods, including machine learning techniques, is explored, and several areas are identified in which changes to current practices would improve the quality, quantity, consistency, and accessibility of seabed image-derived data. Photographic surveying of the seabed is the only non-destructive sampling method available to us that generates quantitative data on fauna, habitats, and substrata at spatial scales relevant to exploration and management of New Zealand’s Exclusive Economic Zone. These characteristics become increasingly valuable as greater emphasis is placed on spatial management of benthic impacts and seabed resources in the New Zealand region. The past decade has seen increasing use of seabed imaging surveys and it is now.....
