Summary
Marine Base Maps for the Coastal Zone (Marine grunnkart i kystsonen) is a project aimed at producing user-oriented maps of the Norwegian coastal zone with a special focus on the seabed. In 2020, three coastal sites were permanently declassified to allow the acquisition of new types of datasets and the development of new methods to produce marine base maps. One of these sites is the seabed surrounding the Fjøløy and Klosterøy islands situated 25 km north of Stavanger. This report introduces the datasets that were acquired on this site between 2020 and 2022 for the purpose of method development. These include three airborne LIDAR surveys (including one from an Unmanned Aerial Vehicle), three airborne photography surveys leading to three orthophoto imageries, one airborne hyperspectral imagery survey, two multibeam sonar surveys (including one using Unmanned Surface Vessels), and a new set of ground-truth data from a variety of sensors including video transects, water sampling, and spectrometry. This report also summarizes pre-existing and relevant datasets on this study site, and introduces the preliminary methods developed to produce marine base maps from these datasets, whether from the contractors or the collaborators leading the project
