#' MSDF MPA assessment area boundary box.
#' 
#' The spatial extent of the MPA assessment areas was defined 
#' as the marine waters surrounding the EU countries whose outer limit is defined 
#' by the 200 NM boundary from the coast (possibly coinciding with formally 
#' recognised EEZ boundaries) or the equidistance (in cases of opposite neighbouring 
#' EU countries), or by the presence of a boundary defined by an agreed treaty. 
#' However, since no formal boundary of this map exists and since this limit 
#' coincides with the boundary of the maritime area (water column) submitted by 
#' EU Member States under MSFD Articles 8, 9 and 10 in the Eionet Central 
#' Data Repository (CDR) ), the decision was taken to use the MSFD Region/Subregion 
#' boundary shapefile assembled in 2013 by ETC/ICM (ETC/ICM, 2013), 
#' based on EU Member States reported data integrated with information from the 
#' Flanders Marine Institute (VLIZ) Maritime Boundaries (version 7) to 
#' delimit the MPA assessment areas
