In the Amundsen Sea, warm water from the shelf break can flood the continental shelf and enter neighbouring ice shelf cavities, driving some of the highest basal melt rates observed in the Antarctic. Here, we investigate the role of submesoscales in transporting warm water into and between connected ice shelf cavities. Recent observational and modelling studies have highlighted the importance of high-resolution bathymetry in ice shelf cavities for accurate understanding of mixing processes. However, observational studies have limited spatial and temporal resolution and are both risky and expensive. Here, we fill this gap by presenting daily-averaged results from a high-resolution (200 m horizontal, 10 m vertical) reanalysis-forced ocean model, MITgcm (setup as in Poinelli et al 2025a,b). We examine the transport of warm water into the Dotson and Crosson ice shelf cavities and the connection between these cavities. High resolution topography and ice shelf draft allows us to investigate the role of water column thickness in steering submesoscale features in these cavities.
