The impact of sedimentary alkalinity release on the water column CO2 system in the North Sea
It has been previously proposed that alkalinity release from sediments can play an important role in the carbonate dynamics on continental shelves, lowering the pCO2 of seawater and hence increasing the CO2 uptake from the atmosphere. To test this hypothesis, sedimentary alkalinity generation was quantified within cohesive and permeable sediments across the North Sea during two cruises in Septe...
متن کاملMeasurement of community metabolism and significance in the coral reef CO2 source-sink debate.
Two methods are commonly used to measure the community metabolism (primary production, respiration, and calcification) of shallow-water marine communities and infer air-sea CO2 fluxes: the pH-total alkalinity and pH-O2 techniques. The underlying assumptions of each technique are examined to assess the recent claim that the most widely used technique in coral reefs (pH-total alkalinity), may hav...
متن کاملImpact of rainbow trout (Oncorhynchus mykiss) farm effluents on water physico-chemical parameters of Ryjab River (Kermanshah province)
The impact of rainbow trout farm effluents on water physico-chemical parameters of Ryjab River was investigated. Five stations were considered at different parts of the river. Station 1 located at the headwaters of the river, station 2 after nearly 30 percent of fish farms, station 3 after 60 percent of fish farms, station 4 after the last fish farm and station 5 located one kilometer after the...
متن کاملWater quality and sedimentary analyses of Siddheshwar dam (India) for assessing irrigational suitability
The physico-chemical properties of water and sediments therein were analyzed for assessing the suitability of Siddheshwar dam (India) waters for irrigation purpose. The physical parameters include total dissolved solids and electrical conductivity. The chemical parameters studied include pH, free carbon dioxide, total hardness, calcium hardness, magnesium hardness, phenolphthalein alkalinity, t...
متن کاملModeling the dissolution of settling CaCO3 in the ocean
concentration, which, on glacial-interglacial timescales, is involved in the regulation of atmospheric pCO2. The saturation state of the ocean with respect to calcium carbonate suggests that any dissolution of calcium carbonate takes place not in the water column but at the seafloor. On the other hand, several authors suggest that a significant part of the dissolution takes place in the upper p...
