Seafloor photographs, offshore Canada

Photographs of the seabed have been collected during marine expeditions of the Geological Survey of Canada Atlantic and Pacific for over 50 years. Typically, a sequence of 10 to 20 photos are taken at a single station as the vessel drifts with prevailing winds and currents and the camera is repeatedly lowered to and raised from the seafloor. The suite of photos from each station may best be considered a representative ensemble from the proximal area. Only in the more recent expeditions, where differential GPS and ultra-short baseline positioning is used in camera positioning, is the relative positional information given for each photo meaningful in interpreting the sequence as a transect. Reduced-scale, thumbnail photos are displayed for the sequence of photos taken at each station. Each photo is labelled with the expedition id, the station number and the photo number.

Description
Title: Creation of the WMS of Seafloor photography -- Description: Des photographies du fond marin sont prises à l'aide de caméras sous-marines embarquées aux stations visitées lors d'expéditions marines de la CGC (Atlantique et Pacifique) depuis plus de cinquante ans. Habituellement, une séquence de 10 à 20 photos est prise à la station, pendant la dérive du bâtiment. Les photographies du fond marin ont été téléchargées dans la base de données d'expédition, aux emplacements des stations visitées lors des expéditions. Les photographies du fond marin, les informations relatives aux stations et les autres informations pertinentes ont été exportées de la base de données d'expédition dans un fichier KML. Le service de cartographie web a été créé à partir des données en format KML.
