“…4 b) [ 30 ]. The other phenomena demonstrated the importance of upwelling on the vertical mixing—a massive methane release from the water surface to the atmosphere—in a brackish lake, suggesting the upwelling may also enhance and release more DIC after collapsing stratification [ 35 ]. Therefore, we calculated how much DIC the phytoplankton reduced due to photosynthesis from 2010 to 2018 ( Fig.…”
