Description
The Lake Balaton sediment database contains the laboratory test results of a detailed survey (a total of 5560 samples) on the physico-chemical properties of the lake bed sediments carried out in the 1970s and 80s. Mixed sediment samples were taken from the upper 10 cm layer with an Ekman-Birge sediment sampler. The purpose of the survey was a detailed investigation of the lake bed sediment for the better understanding the progressive eutrophication process. The published dataset includes the following parameters (remark:missing values are replaced with '-2' in the database):
- pH (KCl): measured with potenciometer
- CaCO3 (%): measured with Scheibler's calcimeter
- organic carbon (%): measured with Tyurin method
- total nitrogen (mg kg-1): measured with Kjeldahl method
- soluble phosphorus (P2O5 in mg kg-1): measured in ammonium-lactate (AL) extract with atomic adsorption spectrophotometry
- potassium (K2O in mg kg-1): measured in ammonium lactate (AL) extract with flame photometer
- magnesium (mg kg-1): measured in KCl extract with atomic adsorption spectrophotometry
- zinc (mg kg-1): measured in EDTA + KCl extract with atomic adsorption spectrophotometry
- copper (mg kg-1): measured in EDTA + KCl extract with atomic adsorption spectrophotometry
- manganese (mg kg-1): measured in EDTA + KCl extract with atomic adsorption spectrophotometry
