Antarctic krill (Euphausia superba) is an important species in the Southern Ocean ecosystem. Survival through their first winter is thought to be critically dependent on the presence of sea ice and is a key factor in the successful recruitment of young krill and in maintaining an abundant population of krill. As larval and juvenile krill grow and develop, they can be transported over a large distance with ocean currents or drifting sea ice. Given the predicted changes in sea ice associated with climate change, improving understanding of the factors influencing the recruitment success of krill populations has been identified as a major research priority. Leveraging a 32-year dataset (1987 – 2018) from the high-resolution ocean-sea ice model ACCESS-OM2 (0.1-degree resolution), we employed Lagrangian particle tracking. Virtual particles released and tracked over 6 months (April to October) revealed fine-scale interannual variability in over-winter transport pathways, shedding light on spawning regions to observed high-density areas post sea ice retreat. Our study delineates potential overwintering habitat areas and their destinations, influenced by dynamic interactions of sea ice and oceanographic variables. These insights enrich global understanding of krill's ecological and economic significance, informing sustainable Southern Ocean krill management strategies amidst climate variability.
