Total alkalinity change: The perspective of phytoplankton stoichiometry
Sign Up to like & getrecommendations! Published in 2024 at "Limnology and Oceanography"
DOI: 10.1002/lno.12597
Abstract: Many biogeochemical processes change total alkalinity: this has been reported for carbonate precipitation and dissolution, uptake and release of various nitrogen‐containing compounds, uptake of phosphate, sulfate reduction combined with methane oxidation. However, the list is… read more here.

DOI: 10.1002/lno.70248
Abstract: The contribution of organic alkalinity (ADOM), derived from dissolved organic matter, to coastal acid–base chemistry remains poorly understood, particularly regarding its spatial, seasonal, and compositional variability. This study examines ADOM dynamics across distinct Korean coastal… read more here.
