Preferential sequestration of terrestrial organic matter in boreal lake sediments
The molecular composition and origin has recently been demonstrated to play a critical role in the persistence of organic matter in lake water, but it is unclear to what degree chemical attributes and sources may also control settling and burial of organic matter in lake sediments. Here we compared the annual contribution of allochthonous and autochthonous sources to the organic matter settling...

متن کاملDoes terrestrial organic carbon subsidize the planktonic food web in a clear-water lake?
Allochthonous organic carbon can subsidize consumers in aquatic systems, but this subsidy may only be significant in relatively small systems with high organic matter loading. We tested the importance of allochthonous carbon to consumers in a relatively large (258,000 m2) clear-water lake by adding HCO3 daily for 56 d. Dissolved inorganic carbon (DIC) was substantially enriched in 13C by the ad...
متن کاملEstimation of groundwater inflow situation using fuzzy logic: a case study (Beheshtabad water conveying tunnel, Iran)
Water inflow is one of the most important challenges in the underground excavations. In addition to inducing working conditions and environmental problems, it decreases the stability and quality of the surrounding rocks. The direct method of measuring rock mass hydraulic conductivity consists of drilling the boreholes and observing the rate of fluid lost in the boreholes. Applying this method i...
