“…10 was derived for oxic decomposition of TOC in pelagic sediments. Dissolved oxygen in interstitial waters is depleted in the upper few centimeters of open-lake sediments in Lake Superior (Glass and Poldoski 1975) agreement between our measured decay rates and those predicted by Eq. 10 is much better than what might have been anticipated, given the differences between lacustrine and pelagic marine enviromncnts.…”

Seventeen box cores from Lake Superior were analyzed for total organic carbon (TOC), porosity, and 210Pb activity. The data were trsed to determine relationships among bulk scdimentation rates, TOC sedimentation rates, and TOC degradation rates with depth in the core. Results are compared with predictive eqllations for TOC sedimentation rates and degradation rates in the oceans and show some striking similarities bctwcen the behavior of TOC in Lake Superior and in hemipclagic and pelagic marine environments.

“…Dissolved silica in Lake Erie sediments does not seem to have been measured previously. My data for Lake Superior show, in general, lower concentrations than those reported by Callender (1969) and Glass and Poldoski (1975). Disparities between my results and other published data could have resulted from different handling of the sediment samples before the pore waters were expressed.…”

“…insight into the diagenesis of aluminosilicates in Great Lakes sediments can be gained from studies of dissolved silica in interstitial waters, Silica concentrations in pore waters from Lakes Ontario, Erie, and Superior sediments reported by Kramer (1967), Callender (1969), Sutherland (1970), Weiler (1973), and Glass and Poldoski (1975) are subject to possibly large errors due to "temperature of squeezing" effects (see Fanning and Pilson 1971). I report here dissolved silica concentrations in interstitial waters from the three lakes obtained at in situ temperatures and propose a deterministic reaction model to explain the observed concentrations.…”

The distribution of dissolved silica in pore waters from Lakes Ontario, Erie, and Superior sediments is not directly related to the deposition of diatomites from the overlying water. It is proposed that silica concentrations in the pore waters are controlled by dissolution of fcrroaluminum silicate, AI,,Fe,,"+(SiO,),(OH)~~,-~~. The cryptocrystalline complex is formed in the sediments by the reaction of biogenic silica with aluminum and ferric oxyhydroxides or by the hydrolysis of clay minerals. A massive episodic flux of biogenic silica to the sediments follows the crash of diatom blooms. Most of the biogenic silica is however dissolved in the water column or at the sediment-water interface; a small fraction is fixed permanently in the sediments as the cryptocrystalline complex. Budget calculations show that regeneration of silica from Ontario and Erie sediments far exceeds annual input from external sources.

The anomalous behavior of manganese and nickel is interesting. In the case of manganese, filtration of the insoluble hydrated oxides removes most manganese (sample 2), but the purification treatment leaves over 90% of the manganese in solution (sample 3). We suspect that in the former case, insoluble manganese dioxide is formed via oxidation by dissolved oxygen and is filtered off. In the latter case, the reduction step keeps manganese in the +2 oxidation state, which apparently remains in solution as an hydroxo complex.
