Data and code from: You shall not pass, the Pacific oxygen minimum zone creates a boundary to shortfin mako shark distribution in the Eastern North Pacific Ocean

Shoaling of large oxygen minimum zones (OMZs) that form along eastern margins of the world’s oceans can reduce habitat availability for some pelagic fishes. Our aim was to test the hypothesis that habitat compression caused by shoaling of the Pacific OMZ in tropical regions creates a boundary to the southern distribution of shortfin mako sharks (Isurus oxyrinchus) in the Eastern North Pacific Ocean., Satellite tagging of shortfin mako sharks captured in long line or sportfishing equipment in the northwest Atlantic (2013 - 2020) and northeast Pacific (2003-2016) Oceans. Sharks were tagged with fin-mounted satellite-linked radio tags (SLRT), and a subset of sharks in the Pacific were also tagged with pop-up archival tags (PAT). 
Location
Eastern North Pacific and Western North Atlantic oceans.
Methods
We compared environmental conditions between areas used by satellite-tagged mako sharks in the Eastern North Pacific, encompassing the world’s largest OMZ, to those used in the Western North Atlantic where no OMZ is present. In the Pacific we quantified the effects of temperature and dissolved oxygen (DO) on depth use and tested if sharks spent less time in areas with strong habitat compression over the OMZ than expected by chance.
Results
The southern distribution of sharks in the Pacific corresponded with the apex of OMZ shoaling in the North Equatorial Current.
