In chihlinwei/SCC85: Seafloor Climate Change Projections from CIMP5

#' Model-Averaging Linear Detrended Standard Deviation of Seafloor Climatic Data during 2041 to 2060
#'
#' Standard deviation of projected (RCP8.5) export POC flux to seafloor, bottom dissolved oxygen concentration, hydrogen ion concentration
#' and temperature were calculated 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).
#'
#' @details
#' Yearly linear-detrend standard deviation from 2041 to 2060 were calculated for the GFDL-ESM-2G, IPSL-CM5A-MR
#' and MPI-ESM-MR respectively. Ensemble average of the standard deviation was calculated among the three models for the periods of 2041 to 2060.
#' 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/}.
