UK Polar Data Centre, Natural Environment Research Council, UK Research & Innovation. https://doi.org/10.5285/8e59f849-5b93-438e-a5e0-3c65636f9053 This dataset contains occurrence records for ten Southern Ocean myctophid fish species that have been downloaded and cleaned from the online biodiversity repository GBIF. As well as providing GBIF documented metadata for each occurrence record, this dataset provides environmental conditions - specifically bathymetry, temperature, salinity, dissolved oxygen and net primary productivity - for each record. Both sea-surface and depth-specific values for the temperature, salinity and oxygen variables are given in separate data files. A third data file of corresponding background points and their associated environmental conditions is also provided. Together these data were used as input files for the MaxEnt ecological niche models within the peer reviewed article: Freer JJ, Tarling GA, Collins MA, Partridge JC, Genner MJ (2020) Estimating circumpolar distributions of lanternfish using 2D and 3D ecological niche models, Marine Ecology Progress Series.

For the 2D model approach, occurrence and background points were matched to the appropriate environmental conditions using the "prepareSWD" function from the R package "SDMtune". Sea surface conditions are matched to all records, regardless of the depth they were caught at. For the 3D model approach, occurrence and background points were matched to the appropriate environmental conditions using the "depth_extract" function from Duffy and Chown (2017) source code available at: https://figshare.com/articles/Duffy_Chown_MEPS12011_model_virtualspecies/4315052. This ensures each occurrence or background point is only matched to the environmental conditions from the depth closest to the depth from which the record came from.

Data collection: All analyses were carried out in R version 3.5.3. Data quality: Occurrence records for all ten species were downloaded from the Global Biodiversity Information Facility (GBIF). These occurrence records represent those remaining after undertaking following quality assurance and control processes. Unreliable data, which included records with identical latitude and longitude, and records with a latitude and longitude corresponding to a terrestrial location, were removed. Due to high sampling bias towards austral spring and summer seasons, only records from the months October-March were kept for analyses. Furthermore, only occurrence records from 1960 to 2010 were retained, to correspond to a similar baseline period of available environmental data. Duplicate records were excluded from model runs. Citations for all data (occurrence and environmental data) are given in the Reference section. asNeeded completed
