We develop a mechanistic model combining thermal and food requirements for krill egg production, with predation pressure post-spawning, to predict regions that could support high larval production (spawning habitat). We optimise our model on regional data using a maximum likelihood approach and then generate circumpolar predictions of spawning habitat quality. The uploaded datasets represent model predictions of seasonal circumpolar spawning habitat quality of Antarctic krill as well as composite data of the circumpolar mean annual number of weeks in which modelled spawning habitat quality is higher than the summer 80th percentile. {"type": "Polygon", "coordinates": [[[-180.0, -90.0], [180.0, -90.0], [180.0, -40.0], [-180.0, -40.0], [-180.0, -90.0]]]} -180.0 180.0 -90.0 -40.0 Antarctic krill Ecosystem Modelling Euphausia superba Krill spawning habitat index (values 0-1) Southern Ocean DATA ACCESS - krill spawning habitat [.nc files] documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
