The dataset contains true presence and modelled pseudoabsence location data for Atlantic bluefin tuna (Thunnus thynnus; ABFT). At each location data for 13 remotely sensed environmental variables is provided, including: bathymetry (m), rugosity (m), absolute dynamic topography (m) and it’s spatial standard deviation, log surface chlorophyll-a (mg m-3), mixed layer depth (m), mean primary productivity over the top 200m of the water column (mg m-3), mean oxygen over the top 200m of the water column (mmol m-3), sea level anomaly (m) and it’s standard deviation, sea surface temperature (°C) and it’s spatial standard deviation, and log eddy kinetic energy (m2 s-2).

Description of the data and file structure

The data is provided as a .csv file and can easily be read into R. The data may be used to produce further species distribution models.

The .csv file has 18 columns:

1. TagID - identification of the individual pop-up satellite archival tag
2. Longitude
3. Latitude
4. Presence - ‘0’ represents modelled psuedoabsence data and ‘1’ represents true presence data
5. Date
6. bathy - Bathymetry (m)
7. bathy_sd - Rugosity (m)
8. adt - Absolute dynamic topography (m)
9. adt_sd - Absolute dynamic topography standard deviation (m)
10. l.chl - Log surface chlorophyll-a (mg m-3)
11. mld - Mixed layer depth (m)
12. PPupper200m - mean primary productivity over the top 200m of the water column (mg m-3)
13. sla - Sea level anomaly (m)
14. sla_sd - Sea level anomaly standard deviation (m)
15. eke - Log eddy kinetic energy (m2 s-2)
16. oxy200m - Mean oxygen over the top 200m of the water column (mmol m-3)
17. sst - Sea surface temperature (°C)
18. sst_sd - Sea surface temperature standard deviation (°C)

NAs indicate gaps in the data frame whereby remotely sensed environmental data was unavailable.
