Fig. 4: Pore fluid silicon concentrations and stable isotopic compositions from Greenland, and a global compilation of benthic dissolved silicon fluxes.
From: Insights into silicon cycling from ice sheet to coastal ocean from isotope geochemistry
a Pore fluid chemistry [DSi] and (b) stable Si isotope composition for a shelf location in the Godthåb Trough, near Nuuk48 and within Nuup Kangerlua fjord, Southwest Greenland49. c Compilation of benthic DSi fluxes from porewater profiles (i.e., diffusive only fluxes, hatched bars) and core incubations (solid bars) from the Arctic margins75,76, coastal Southwest Greenland48, glacial fjords from Greenland49, Southern Ocean (compiled by ref. 48), glacial fjords from Patagonia15, and West Antarctic Peninsula46. The numbers in parentheses are the number of cores used for porewater profiles/core incubations; bars show range of values for each location (unless only one observation has been made, in which case the bars show propagated errors). See Fig. 1 for locations. d Global compilation of benthic DSi fluxes based on diffusive pore fluid profiles from open ocean, coastal and fjord sites (compiled by ref. 15).
