(Collaborative Research: Life after Death: Do Inactive Sulfides Fuel a Unique Ecosystem at the Deep Seafloor?) | This dataset includes counts by taxon for megafauna in images collected during surveys with deep-submergence vehicles at inactive sulfide mounds near the 9 50' N hydrothermal vent field on the East Pacific Rise. Images were collected with a down-looking digital still camera. We provide image areas for estimating megafauna density (counts per area of seafloor). Here we provide data from three surveys: one during HOV Alvin Dive 5044 at Lucky's Mound on 25 December 2019 on cruise AT42-21 and two during ROV Jason II Dives 1309 and 1311, on the oceanic rise (between Lucky's Mound and Sentry Spire) on 7 April 2021 and at Sentry Spire on 9 April 2021, respectively, on cruise RR2102. Megafauna were manually annotated to morphotype using ImageJ software. Morphotypes were identified to the lowest taxonomic level and assigned to a feeding mode. This dataset is provided in two formats: long-format comma-separated variable (csv) file and wide-format Excel (xlsx) file. This dataset is analyzed in a manuscript by Meneses et al. (2024).\n\ncdm_data_type = Other\nVARIABLES:\nFile_Name (unitless)\nSite (unitless)\nHabitat (unitless)\nCorrected_Area_m2 (meters squared)\nverbatimIdentification (unitless)\nFeeding_Mode (unitless)\nindividualCount (integer count)\nWoRMS_scientificName (unitless)\nWoRMS_scientificNameID (unitless)\neventDate (unitless)\nlatitude (Decimallatitude, degrees_north)\nlongitude (Decimallongitude, degrees_east)\ndepth (Depth_m, m)\nVehicle_Altitude_m (meters)\nAngleCategory (unitless)\nAdjustment_Value (unitless)\nUseable_Proportion_of_Image (unitless)\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_932975_v1_fgdc.xml | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_932975_v1_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_932975_v1/index.htmlTable | https://www.bco-dmo.org/dataset/932975
