Dorado Outcrop Vent and Non-Vent community composition from JVV images
Abstract
Dorado Outcrop Vent and Non Vent community composition from JVV images contains the observations of community to the family level in 8 vent and non-vent zones around the Dorado Outcrop. 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 images in the Jason Virtual Van (http://4dgeo.whoi.edu/webdata/virtualvan/html/VV-at26-09/index.html). 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 NCEI (Metadata ID: gov.noaa.ngdc.mgg.multibeam:AT26-09-auv_Multibeam MBES). Substrate was identifed manually. Temperature data was collected in AT26-09 with AUV Sentry. 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.
