Animation of Northwest Atlantic Ocean and Shelf monthly salinity/temperature change under an atmospheric CO2 doubling scenario from GFDL CM2.6. Monthly salinity and temperature from the model are averaged between 150200 m depth to represent Slope Water intrusions into the Northeast Channel. Ocean depths greater than 150 m are shown. CM2.6 monthly salinity and temperature are animated under an 80-year run of atmospheric CO2 increasing 1% per year such that it doubles at year 70 and continues increasing by 1% per year until year 80. 2
