sps - a 11603 x 10 data.frame for testing cpue and mapping functions

Description

sps - a 11603 x 10 data.frame for testing CPUE functions containing simulated trawl shot CPUE data for the years 2003 - 2014, including details of year, month, day, vessel, catch, longitude, latitude, depth trawled in meters, a daynight identifier, and effort. The cpue and log(cpue) can be calculated from this data.

Format

A data frame with 10603 x 10 variables:

• YearThe year in which fishing takes place

• MonthThe month in which fishing took place

• Vessela code uniquely identifying vessels through time

• catch_kgliterally the catch of the species in the shot in kg

• Longthe longitude of the start of the trawl shot

• Latthe latitude of the start of the trawl shot

• Depththe average depth of trawling in meters

• DayNighta code denoting the daynight status D = day, N = night, M = mixed

• Effortthe hours trawled

• ZoneThe fished area split into three latitudinal zones
