In chihlinwei/SCC85: Seafloor Climate Change Projections from CIMP5

#' Coefficient Variation of the Mean Seafloor Climatic Data among CIMP5 Models during 2081 to 2100
#'
#' Coefficient variation of the mean 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).
#'
#' @details
#' Yearly mean from 2081 to 2100 were calculated for the GFDL-ESM-2G, IPSL-CM5A-MR
#' and MPI-ESM-MR respectively. Coefficient variation of the mean was calculated among the three models for the periods of 2081 to 2100.
#' 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/}.
