Multi-site high resolution seabed topographical surveys (Maupiti Hoe, Niau, Socoa, Ars-en-Ré, Parlementia, Banneg)

The present dataset is based on a nine site study of fine seabed topography in intertidal zones. Four coral sites (Maupiti A, B and C and Niau islands) and five rocky sites (Ars en Ré, Socoa, Parlementia A and B and Banneg island) have been explored. The data has been gathered using on-foot GNSS RTK for all sites (Trimble R8/R8S and Leica sytems) except Banneg island, where aerial Lidar data from Litto3D program has been used. The horizontal resolution varies between 3.8 and 12cm allowing to describe a wide range of spatial scales (generally over 3 spectral decades). The data has been processed to explore the statistical and spectral metrics which can be used to characterize the architectural complexity of seabeds.

Purpose: Le présent ensemble de données est basé sur une étude de neuf sites de topographie fine des fonds marins dans les zones intertidales. Quatre sites coralliens (Maupiti A, B et C et îles Niau) et cinq sites rocheux (Ars en Ré, Socoa, Parlementia A et B et île Banneg) ont été explorés. Les données ont été collectées à l'aide de GNSS RTK à pied pour tous les sites (systèmes Trimble R8/R8S et Leica) à l'exception de l'île de Banneg, où les données aériennes Lidar du programme Litto3D ont été utilisées. La résolution horizontale varie entre 3,8 et 12 cm permettant de décrire une large gamme d'échelles spatiales (généralement sur 3 décennies spectrales). Les données ont été traitées pour explorer les métriques statistiques et spectrales qui peuvent être utilisées pour caractériser la complexité architecturale des fonds marins.
