In chihlinwei/SCC85: Seafloor Climate Change Projections from CIMP5

#' Exposure to Climate Change Hazard during 2081 to 2100 based on linear detrend standard deviation
#'
#' Historical and projected (RCP8.5) export POC flux to seafloor, bottom dissolved oxygen concentration, hydrogen ion concentration
#' and temperature were averaged from the Geophysical Fluid Dynamics Laboratory’s ESM 2G (GFDL-ESM-2G), Institut Pierre
#' Simon Laplace’s CM6-MR (IPSL-CM5A-MR) and Max Planck Institute’s ESM-MR (MPI-ESM-MR) within the Coupled Models
#' Intercomparison Project Phase 5 (CIMP5). Exposure to climate change hazard was estimated as the difference between the
#' projected (RCP8.5) and historical climatic data divided by the standard deviation during the historical period.

#' @details
#' Yearly mean and linear-detrended standard deviation from 1951 to 2000 (historical), 2081 to 2100 (rcp8.5) and 2081 to 2100
#' (rcp8.5) were calculated for the GFDL-ESM-2G, IPSL-CM5A-MR and MPI-ESM-MR respectively. Ensemble average of the mean and
#' standard deviation were calculated among the three models for the periods of 1951 to 2000 and 2081 to 2100 respectively.
#' Exposure to climate change hazard was calculated as \code{\link{cimp5_2081_2100_ch}} divided by \code{\link{cimp5_1951_2000_ds}}.
#' The export POC flux at seafloor was compute from the export production at 100 m (epc100) using the Martin curve (Martin et al., 1987)
#' following the quation: \eqn{Flux = epc100*(depth/export depth)^-0.858}. The depth use \code{\link{etopo1}} and export depth was set to 100 m.
#' All CIMP5 data were download from \url{https://esgf-node.llnl.gov/search/esgf-llnl/}.
