This file contains the backgound data points used by the MaxEnt modelling algorithm and the present day environmental conditions associated to each background location. Background data points were selected from within 2 decimal degrees of mesopelagic fish records across the study region to control for spatial sampling bias. 
Data columns and units are: 

NAME = background data identifier
LON = longitude (decimal degrees)
LAT = latitude (decimal degrees)
BATHYMETRY = bathymetry (metres)
O2 = dissolved oxygen at the sea surface (mmol-m3)	
PP = primary productivity (nmol m-2 s-1)	
SAL = sea surface salinity (PSU)	
SAL200 = salinity at 200m (PSU)
TEMP = sea surface temperature (degrees celcius)	
TEMP200 = temperature at 200m (degrees celcius)

Data sources:

1. All occurence records were obtained from the Global Biodiversity Information Facility (GBIF; http://www.gbif.org/). 

2. Interpolated climatologies for temperature, oxygen and salinity variables were extracted from the World Ocean Atlas 2013 database (https://www.nodc.noaa.gov/OC5/woa13/) at a resolution of 0.25° x 0.25° for the months October-March across the baseline temporal period 1956-2005.

3. Bathymetry data (i.e. maximum water depth) were obtained from the SRTM30 global elevation and bathymetry dataset(https://topex.ucsd.edu/WWW_html/srtm30_plus.html) at the original resolution of 30 arc seconds and were re-sampled to the same resolution as the other variables using the bi-linear resample tool in ArcGIS v.10.4.1.

4. Primary productivity is the primary organic carbon production by all types of phytoplankton and data used correspond to the ensemble mean of 1956-2005 Earth System Model historical runs. These data were extracted from the NOAA/ESRL Physical Sciences Division Climate Change Web Portal (https://www.esrl.noaa.gov/psd/ipcc/ocn/).
