Period of layers
           
The layers for the future were developed under the new representative concentration pathway scenarios (RCP):
The RCP26, a peak-and-decline scenario ending on very low greenhouse gas concentration levels by the end of the 21th century, the RCP45 and RCP60 where concentration levels stabilize, and the RCP85, a scenario of increasing emissions over time leading to high greenhouse concentration levels (Get to know the RCP).

Depth of layers
       
The benthic layers were produced with an interpolation process considering the geographic position and depth of cells, as inferred from a bathymetry layer. Since focal cells included a wide range of depth values, benthic layers are available for the minimum, average and maximum depths.
