This file only includes observations for PMF species or habitat components from digital still images.
Only images with <25% of the image obscured are included.

Column 1: Year [2012, 2013, 2014, 2015, 2016, 2017]
Column 2: Cruise_ID - cruise number with number letter code
Column 3: Image_ID - the unique identifier for digital still images within each cruise
Column 4: DecLat - latitude information in decimal degrees
Column 5: DecLong - longitude information in deicmal degrees
Column 6: Box_ID - unique survey box identifier, conserved across years
Column 7: Sediment - sediment code for the image, see abbreviations
Column 8: Habitat - habitat code for the image, see abbreviations
Column 9: Community - community code for the image, see abbreviations
Column 10: DSI_Area_m2 - size of the patch of seafloor captured in the digital still image, in meters squared
Column 11: Area_Obscured_% - percentage of the image that is obscured. '0' means zero percentage obscured, i.e. the whole image is visible.
Column 12: Area_Obscured_m2 - size of the area within the image that is obscured, in meters squared. '0' means zero area obscured, i.e. the whole image is visible.
Column 13: Viewed_Area_m2 - size of the area within the image that is visible (= column 10 - column 12) in meters squared
Columns 14 - 35: Abundance of each taxon observed within an individual image. Zero ('0') means the taxon was not observed in that image.
Abundance is generally the count of individuals for each taxon within an image (n) or density of individuals within an image per meter squared (n.m2).
For Parazoanthus anguicomus, 'occurrence' (o = count of discrete patches) or 'occurrence' density per meter squared (o.m2) is also provided.
For Swiftia pallida communities with sponges or Caryophyllia smithii (SC) and burrowed mud with seapens (BS) presence/absence (P/A) is used to capture abundance information where 1 = Present and 0 = Absent.
Column headers are generally abbreviations of taxonomic names, see abbreviations lists.
