In this paper a series of geochemical investigations are reported with respect to calcium contents in different waters collected from the sea off the coast of Cananéia, the lagoon surrounding Cananéia Island and from Nóbrega river (one of the saline branches from the lagoon, also called "marigot"). An almost direct relation of calcium to chlorinity, 0.02168 in average, similar to that of the outer Atlantic water, 0.02156, was observed in the coastal water. This indicates that the terrigenous supply of calcium might not contribute very much to the calcium content in the coastal water. The inflow of land water to the lagoon of Cananéia does not increase the calcium content of the lagoon water, where a slight depression of the Ca/Cl gradient (namely 0.0206) was observed. This characteristic of the calcium distribution is more remarkable in the water of the "marigot", branching off from the lagoon. An extremely low gradient of calcium to chlorinity, 0.0177 is one of the geochemical characteristics found in tropical estuaries where active bacterial decomposition of deposited organic materials renders the geochemical properties of the water more acid and more reduced. The low content of calcium in land water, 4-6 mg/Ca/kg, has also of course, a close relationship to this peculiar aspect of the calcium distribution in the coastal water, and further in the Atlantic water off the Brazilian coast.

Permafrost thawing and erosion results in the enrichment of northern lakes by soil organic matter. These allochthonous inputs favour bacterial decomposition and may cause the draw-down of dissolved oxygen to anoxic conditions that promote methanogenesis. Our objective in the present study was to determine the seasonal variations in dissolved oxygen in a set of permafrost peatland lakes in subarctic Quebec, Canada, and to relate these changes to metabolic rates, ice cover, and mixing. The lakes had high dissolved organic carbon concentrations, and their surface waters in summer had greenhouse gas concentrations that were up to one (CO2) to three (CH4) orders of magnitude above air-equilibrium values, indicating their strongly heterotrophic character. Consistent with these observations, the peatland lakes had elevated rates of bacterial production and oxygen consumption. Continuous measurements of oxygen by in situ sensors and of ice cover by automated field cameras showed that the lakes became fully anoxic shortly after freeze-up. The waters were partially re-oxygenated by mixing events in spring and fall, but in one lake, the bottom waters remained anoxic throughout the year. These observations provide a foundation for subsequent biogeochemical and modelling studies of peatland thaw lakes as an abundant class of Arctic freshwater ecosystems.
