Seasonal variations in chemistry and r1atios o f total inorganic carbon of carbonate dissolving waters are considered in the frame-work of a simplified approach dealing explicitly with major ionic s...
The pH, 613c of total dissolved carbon and HCO;, Ca2*, Ca2+ + Mg2+ contents in spring waters were investigated. Changes of these values were recorded for 8 months of 1982 and 1983. The changes were ...
Increasing numbers of studies have recently used stable isotopes of nitrogen (δ15N) and carbon (δ13C) to clarify the source of nutrients in lake water and sediments, the structure and energy flow of f...
southern part. Seasonally, POM with high δ13C and low δ15N has appeared in summer, whereas the opposite is the case in spring and autumn. Horizontally, the summer POM with both higher δ13C and lower δ...
