Circumpolar Antarctic krill spawning habitat
Maintenance and Update Frequency: notPlanned Statement: 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 optimize our model on re...
