Short summary

New hydrographic observations from Disko Bay, Greenland, focus on the previously undersampled autumn to spring seasons. Data collected between 2022 and 2024 reveal seasonal inflow of warm, salty Atlantic water from Baffin Bay, as well as seasonal and spatial variability within cooler Polar Water. The findings establish a framework for interpreting physical variability within Disko Bay and its connection to the west Greenland coastal system.
