Variability of Surface Water pCO₂ in the Canadian Arctic Archipelago From 2010 to 2016

This study provides 6 years of high‐resolution underway measurements of the sea surface partial pressure of CO 2 ( p CO 2sw ), sea surface temperature, and salinity across the Canadian Arctic Archipelago (CAA). Observed p CO 2sw varied regionally, with the northern and central channels of the CAA undersaturated in p CO 2sw (with respect to the atmosphere), while the western regions were typically saturated to supersaturated in p CO 2sw .
