Inorganic and Organic Sulfur in Estuarine Waters

Cycling of Inorganic and Organic Sulfur in Estuarine Waters 

This is further supported by the positive correlation between glutathione and chlorophyll-a concentrations (figure 12.9). Release of glutathione from phytoplankton cells can occur through enzymatic control (Meister and Anderson, 1983) as well as grazing activities by zooplankton.

When comparing DMS sources in estuaries to the shelf and open ocean sources it is clear that estuaries are not a significant source to the atmosphere (table 12.3 Sciare et al., 2002). However, as mentioned earlier, COS and CS2 may represent potentially important sources of S in estuaries (Watts, 2000 Sciare et al., 2002). Concentrations of both these compounds have been found to be 5 to 50 times higher than in coastal and
