This thesis has highlighted the dynamic and interconnected nature of biogeochemical processes at the boundaries of sea ice edges, coastal margins, and open watersheds as observed from space. The combined use of satellite-derived datasets has offered new insights into the physical and biological mechanisms governing these critical zones. Notably, the analysis of Antarctic sea ice edges revealed that changes in sea ice dynamics are influencing phytoplankton blooms, with implications for biogeochemical modeling as the Southern Ocean experiences warming and freshening. In the Arctic, a clear synchrony between terrestrial and marine productivity has been identified, with both domains experiencing a simultaneous rise in primary productivity, closely tied to the warming climate and resulting changes in sea ice and nutrient dynamics. The development of the Coastal Synchrony Index (CSI) provided a novel metric for comparing productivity changes and illustrated the interconnected nature of terrestrial and marine ...
