Short summary
Because of its large physical dimensions and unimpeded connection to the Atlantic Ocean, the St. Lawrence Gulf and Estuary encompass both estuarine and marine environments. The underlying physical and biogeochemical processes are reflected in the spatial pattern of surface-water pCO2 (139–765 µatm). The shallow partially mixed upper estuary was a CO2 source due to microbial respiration, whereas the deep stratified lower estuary was generally a CO2 sink due to phytoplankton photosynthesis.
