GlobalSpatialRisk

Repository containing derived data, R scripts and the GSMP Rpackage for the manuscript "Global spatial risk assessment of sharks under the footprint of fisheries"

r_scripts

\1a_dit

\\1_dit_calc.r

	Calculate point density for individual daily geolocations.
	
	Additional notes:
	 - Example "track_points.csv" contains example data for script reproducibility purposes.

\\2_dit_month_calc.r

	Calculate monthly shark relative density (Dit) for each individual shark in a spatial grid

\1b_gfw

\\1_create_gfw_raster.r

	Calculate monthly rasters of GFW and between-year averages
	
	Additional notes:
	 - Original data obtained from Global Fishing Watch https://globalfishingwatch.org/

\2_fei

\\1_fei_calc.r

	Calculate fishing exposure index (FEI) and percent overlap (%) for each ID in each month
	
	Additional notes:
	 - Example directory "\dit_month_from_1a\" contains example data for script reproducibility purposes, as an output of script "2_dit_month_calc.r".
	 - Example file "eg_grid_data.csv" contains example data for script reproducibility purposes.
	 - Example file "eg_metadata.csv" contains example data for script reproducibility purposes.


\\2_fei_summ_stats.r

	Summary statistics of FEI or % for each ID
	
	Additional notes:
	 - Provided derived data for each tracked ID
	 
\\3_fei_summ_stats_month.r

	Summary statistics of FEI or % for each ID, monthly
	
	Additional notes:
	 - Example directory "2_fei\examples\output\" contains example data for script reproducibility purposes, as an output of script "1_fei_calc.r"

\3_summ_table

\\1_create_summ_table.r

	Summary statistics per species/region

\4_risk_plot

\\1_create_input_table.r

	Create input table for the risk plots; all species within a region

\\2_risk_plot.r

	Risk plots; monthly data for a given species within a region

GSMP_Rpackage

Package to calculate Fishing Exposure Index and Risk based on telemetry data

derived_data

Derived shark data

Rasters of Dit, GFW and FEI
