zbyrec: Zonal(by EEZs) proportions of ICES rectangles in N-Atlantic.

In geoextras: Extras for the 'geo' package

Description

A dataframe giving percentages of statistical rectangles (0.5° latitude by 1° longitude) within EEZs (Exclusive Economic Zones) in the North Atlantic as agreed by NEAFC (North East Atlantic Fisheries Comission) in negotiations on blue whiting zonal attachment using an ICES (International Council for the Exploration of the Sea) rectangle coding system.

Usage

Details

• Column 'rect' is a ICES-code for a rectangle,

• 'area' code in an unknown area coding system,

• 'ices.div' is ICES division,

• columns 'eu' through 'grayzone' give zonal attachment in percentages, agreed on by a working group. Note that these percentages are only approximate, and could be reworked using functions in this package and 'geo',

• columns 'lat' and 'lon' are center positions in the rectangles.
