    dct:description """This is a nutrients product developed from CMEMS product 
NORTHWESTSHELF_REANALYSIS_BIO_004_011. There are two gridded products, yearly 
winter mean nitrogen concentrations, and yearly winter mean phosphate 
concentrations. The data covers the period 1990 - 2014 and is at 0.111° x 
0.067° resolution.

Winter means are also provided for a set of regions used for eutrophication 
assessments: MSFD regions, regional seas, WFD coastal areas, and 
Ecohydrodynamic regions.

Files:

ntra_winter_1990_2012.nc, ntra_winter_2013_2014.nc, phos_winter_1990_2012.nc, 
phos_winter_2013_2014.nc contain gridded winter means for the years indicated. 
2013 and 2014 are in separate files as the model grid changed slightly after 
this point.

ntra_MSFD_winter_means_1990_2014.csv and phos_MSFD_winter_means_1990_2014.csv 
contain winter nitrate and phosphate means for each of the MSFD regions: 
Greater North Sea and Celtic Seas for the years 1990 - 2014.

ntra_RegionalSeas_winter_means_1990_2014.csv and 
phos_RegionalSeas_winter_means_1990_2014.csv contain winter nitrate and 
phosphate means for each of the regional seas (1-8, also known as charting 
progress 2 regions) for the years 1990 - 2014.

ntra_WFD_coastal_winter_means_1990_2014.csv and 
phos_WFD_coastal_winter_means_1990_2014.csv contain winter nitrate and 
phosphate means for each of the WFD coastal assessment regions, for the years 
1990 - 2014.

ntra_Ecohydro_winter_means_1990_2014.csv and 
phos_Ecohydro_winter_means_1990_2014.csv contain winter means for 
Ecohydrodynamic regions (cropped to the MSFD regions).

Corresponding shapefiles for all of these regions are also available 
(MSFD_regions.zip, Regional_seas.zip, WFD_coastal.zip, 
Ecohydrodynamic_regions_cropped.zip)""" ;
