Cairns2020_AnnexG_OtolithImageMetadata.csv: This .csv file (file size 2 kb) provides metadata for the collection of eel otolith images. Files with names starting with EelOtos . . . . : These .tif, .jpg, and .bmp image files are in zipped format with a summed size of 5.3 gb. The files give magnified photos of 1,838 eel otoliths that have been prepared for age reading. Samples are from the Atlantic Provinces of Canada. Individual otolith codes in Cairns2020_AnnexB_EelLengthsAgesEfishingRecords.xlsx and in Cairns2020_AnnexC_EelLengthsAgesDataDefinitions.csv match the codes embedded in otolith image filenames. 2023-07-11 Fisheries and Oceans Canada David.Cairns@dfo-mpo.gc.ca Nature and EnvironmentScience and TechnologyNorth Atlantic OceanGulf of Maine and Bay of FundyGulf of St. LawrenceNewfoundland Shelf and Grand BanksNorthwest AtlanticFishFisheries resources Cairns2020_AnnexA_ReportTablesXLSX https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/Cairns2020_AnnexA_ReportTables.xlsx Cairns2020_AnnexB_EelLengthsAgesEFishingRecordsXLSX https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/Cairns2020_AnnexB_EelLengthsAgesEFishingRecords.xlsx Cairns2020_AnnexC_EelLengthsAgesDataDefinitionsCSV https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/Cairns2020_AnnexC_EelLengthsAgesDataDefinitions.csv Cairns2020_AnnexD_EelLengthsAgesCSV https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/Cairns2020_AnnexD_EelLengthsAges.csv Cairns2020_AnnexE_EelEFishingDataDefinitionsCSV https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/Cairns2020_AnnexE_EelEFishingDataDefinitions.csv Cairns2020_AnnexF_EelEFishingCSV https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/Cairns2020_AnnexF_EelEFishing.csv Cairns2020_AnnexG_OtolithImageMetadataCSV https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/Cairns2020_AnnexG_OtolithImageMetadata.csv ImagesZIP https://pacgis01.dfo-mpo.gc.ca/FGPPublic/American_eel_stock_assessment/images.zip American eel measurements from selected sites (Annex D)ESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/American_eel_measurements_from_selected_sites_AnnexD/MapServer American eel measurements from selected sites (Annex D)ESRI REST https://gisp.dfo-mpo.gc.ca/arcgis/rest/services/FGP/American_eel_measurements_from_selected_sites_AnnexD/MapServer
