From: Fluxes of water, sediments, and biogeochemical compounds in salt marshes
Average dissolved (closed symbols) and biogenic (open symbols) silica concentrations over the average of three summer tidal cycles. Circles, squares, and triangles represent neap, mid, and spring tidal ranges, respectively. Hours one and ten are low tide and represent the strongest marsh export water signal (and highest DSi). Error bars are standard errors (from Vieillard et al. 2011).
