What controls the chemistry of seawater as it freezes? A new collaboration with the Sea ice Environmental Research Facility, University of Manitoba, Canada
In the oceans, some inorganic chemicals - such as barium - show strong associations with the concentrations of essential nutrients and alkalinity leading to their use in a variety of geochemical proxies or archives. However, recent studies in my research group have suggested that some of these associations may break down in the high-latitude oceans. In particular, interactions with sea-ice may be important in controlling regional barium distributions, though the mechanisms underpinning these processes remains to be fully elucidated. We aim to build a new collaboration with the University of Manitoba Sea ice Experimental Research Facility (SERF) facility to investigate the role of physical and chemical processes in controlling inorganic geochemistry of sea ice, using barium cycling as a case study.
