Raster stack for area (km2) of 1 thru 11 classes of benthic seascapes (Harris & Whiteway, 2009)

Source: R/data.R

Global half-degree raster of high seas. Original 0.1 deg cells were multiplied by area and summed to 0.5 deg cells.

Format

A stack in which each layer represents area for given integer class id of benthic seascape corresponding to :

  1. Abyssal, hilly plains, large (arched) uplifted structures, flat abyssal plains, flat, very low PP, very thin sediment (seascape 11)

  2. Abyssal, plains with slightly undulating seafloor, flat abyssal plains, continental rise, very flat, high DO, low PP, very cold (seascape 10)

  3. Abyssal, flat sedimented plains of marginal seas, central rift zone, ridge flanks, marginal seas with hilly bottoms, flat, low DO, thin sediment (seascape 8)

  4. Abyssal, volcanic ridges and highs, central rift zone, ridge flanks, microcontinents, cold (seascape 7)

  5. Abyssal (Hadal), trenches controlled by fracture zones, deep water trenches, large arched uplifted structures, low PP thin sediment, cold (seascape 9)

  6. Lower Bathyal (Abyssal-Hadal), deep water trenches, island arcs, trenches controlled by fracture zones, volcanic ridges and plateaus, very steep (seascape 6)

  7. Lower Bathyal, continental slope see high PP, very thick sediment, warm (seascape 4)

  8. Lower Bathyal, other ridges and plateaus, marginal plateaus, marginal seas with hilly bottom, steep, very low DO (seascape 3)

  9. Lower Bathyal, deep shelf (submerged), marginal plateaus, very high DO, high PP, thick sediment, warm (seascape 2)

  10. Upper Bathyal, shallow shelf, low DO, very high PP. thick sediment very warm (seascape 1)

  11. Lower Bathyal, island arcs, steep, high DO (seascape 5)

Note that seascape numbers differ from those in Harris & Whiteway 2009. Numbers in parenthesis correspond to numbers from Harris & Whiteway 2009.
