Seafloor photographs, offshore Canada

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. 2020-12-09 Natural Resources Canada nrcan.gsc-geosciencedata-donneesgeoscience-cgc.rncan@canada.ca Form DescriptorsNature and EnvironmentScience and Technologymarine sedimentseafloor photographyocean bottomGeologyOcean floorPhotographsSediments Seafloor photographs, offshore Canada - FrenchESRI REST https://maps-cartes.services.geo.ca/server_serveur/rest/services/NRCan/CGC_Collection_photos_fonds_marins/MapServer Seafloor photographs, offshore Canada - EnglishESRI REST https://maps-cartes.services.geo.ca/server_serveur/rest/services/NRCan/GSC_Seabed_Photo_Collection/MapServer Seafloor photographs, offshore Canada - EnglishFGDB/GDB https://ftp.maps.canada.ca/pub/nrcan_rncan/Seas_Mer/SeabedPhotoCollection_CollectionPhotosFondsMarins/GSC_Seabed_Photo_Collection.gdb.zip Seafloor photographs, offshore Canada - FrenchFGDB/GDB https://ftp.maps.canada.ca/pub/nrcan_rncan/Seas_Mer/SeabedPhotoCollection_CollectionPhotosFondsMarins/CGC_Collection_photos_fonds_marins.gdb.zip Seafloor photographs, offshore Canada - EnglishWMS https://maps-cartes.services.geo.ca/server_serveur/services/NRCan/GSC_Seabed_Photo_Collection/MapServer/WMSServer?service=WMS&version=1.3.0&request=GetCapabilities Seafloor photographs, offshore Canada - FrenchWMS https://maps-cartes.services.geo.ca/server_serveur/services/NRCan/CGC_Collection_photos_fonds_marins/MapServer/WMSServer?service=WMS&version=1.3.0&request=GetCapabilities
