This is the code and figures for a part of the chapter on benthic invertebrates of the 2nd World Ocean Assessment Report (WOA II).
This is a collaboration between MarineRegions, the World Register of Marine Species and OBIS:
- the geodata (IHO Sea Areas) are provided by MarineRegions
- species information is provided by the World Register of Marine Species
- species distribution records are provided by OBIS
Query by OBIS: see https://github.com/iobis/woa
WOA benthic invertebrate diversity maps by IHO area and depth (script):
- maps of number of species: species_depth_spec_... .png
- maps of number of records: records_depth_rec_... .png
Different depth categories:
- rec_s200m: < 200 m
- rec_200.1000m: 200 - 1000 m
- rec_l1000m: > 1000 m
A large graph which includes three world maps: IHO_world_graph.png, generated in IHO_world_graph.r
The pdf version provides a vector output of the graph and maps.
You can re-run the full analysis in an RStudio environment by clicking on the button below.
This will open an online RStudio environment (thank you Binder!). To run the analysis, open the 'IHO_world_graph.R' file and execute the code.
