DSMZ-MBNMS Vent and Non-Vent community composition from images and environmental data set

Abstract DSMZ-MBNMS Outcrop Vent and Non Vent community composition from still images collected with ROV Hercules on NA117 contains the observations of community to the family level in 8 vent and non-vent zones around the Octopus Garden and Octocone. Also included are location, subtrate, zone type, TASSE variable values: Easterness, Mean Depth, Northerness, Topographic position index (RDMV), Slope, Standard Deviation, and Surface Depth, BRESS geomorphon, and averate temperature. Methods Observational data was collected by manual identification of 1-minute interval still images in the DSMZ-MBNSM NA117 videos available at: https://www.youtube.com/playlist?list=PL41b0O3MiKnZjVYKiC8zunwc7tGS9L2Az . Observations were identified with the aid of deep sea guides*: HURL, NOAA, and MBARI. BRESS and TASSE variables were extraction for bathymetric grids availble via Marine Geoscience Data System under Compilations as OctopusGarden_MBARI. Substrate was identifed manually. Temperature data was collected in NA-117 with ROV Hercules. Vent and Non-Vent zones were defined by temperature. Environmental and Community data for each image sample were complined in QGIS. Data is identifed as Q for qualitative and C for catagorical. Substrate Catagories: 0: Sheet, 1 Bare Rock, 2 Carbonate, 3 Blocky sheet pillow lobate, 4 Lobate, 5 Pillow, 6 Sediment, 7 Lobate Pillow Mix, 8 Lobate Broken Pillow Mix, 9 Lobate Pillow Contact, 10 Sediment Lobate Contact, 11 Lobate Sheet Mix, 12 Lobate Sediment Mix, 13 Lobate Sheet Contact, 14 Sediment Pillow Mix. BRESS Categories: 1 Flat, 2 Footslope, 3 Ridge, 4 Shoulder, 5 Slope, 6 Valley. Vent/Non Vent Catagories: 1 Non-Vent, 2 Vent.
