The annual cycle of US Northeast continental shelf Cold Pool salinity. A linear trend has been fitted to the black‐highlighted data during the stratified season (April–October. (a) Observed salinity change at 67 m depth from the OOI Pioneer Array PMUI mooring. The ±1σ envelope depicts one standard deviation of interannual variability. (b) Salinity change from the NorthEast Shelf and Slope (NESS) model for all waters below the 10°C cold pool temperature threshold along 70.875°W. The cold pool along 70.875°W is fully eroded by September and no mean cold pool salinity can be computed for the rest of the fall. The ±1σ envelope depicts the combined variability across the cold pool volume on a given day and across all eight model years. Note that the Pioneer Array (a) measures Practical salinity (PSU) while the NESS model (b) advects absolute salinity (g/kg).
