Short-term high-frequency water dissolved carbon dioxide, temperature, dissolved oxygen, salinity and pH data from 8 Estonian lakes in year 2014

This dataset was used in the analysis described in the manuscript by
Khan, H., A. Laas, R. Marcé, B. Obrador. Major effects of alkalinity
on the relationship between metabolism and dissolved inorganic carbon
dynamics in lakes. In review: Ecosystems. This dataset was used to
calculate short term changes of dissolved inorganic carbon (DIC)
concentrations and its variability in Estonian lakes. DIC data were
compared with measured dissolved oxygen (DO) data in lakes covering a
range of different alkalinity levels. Our results suggest that a large
part of the measured variability in DO and DIC reflects non-metabolic
processes. In lakes of lower alkalinity, DIC dynamics appear to be
mostly driven by aquatic metabolism, whereas in lakes of higher
alkalinity calcite precipitation plays a major role on DIC dynamics
and needs to be considered along with metabolism.
