Data for: New spectroscopic method for true color determination in natural water with high agreement with visual methods”
No full textThe program is dedicated to true water color (TWC) calculation by light absorption in visual range from 390 up to 830 nm. Calculation is based on mathematical model of color perception by standard observer using spectral data, contained in text files.
It allows:
1 – To load standard solutions and samples spectra with spectrum conversion into absorption when required;
2 – To save and upload calculation of graduation curve and graduation data;
3 – To calculate true water color and export data to Microsoft (MS) Excel table;
Surce code and data examples are also attached

Lake Onego water chemical composition based on seasonal field surveys in 2019-2021
No full textThe Dataset contains the characteristics of the water chemical composition of Lake Onego (35 stations in different regions of the lake) including the lake outflow Svir' River and the estuarine area of the main tributaries of the lake (rivers Shuya, Vodla, Andoma, and Vytegra). The data were obtained in autumn 2019, spring and summer 2020, and in winter 2021. Detailed information is provided for each station of water sampling (station index, their geographic coordinates, sampling date, sampling depth, temperature, and water chemical composition). The concentration of Na+ and Cl- ions, content of organic matter (TOC, CODMn, CODCr, water color, BOD5), nutrients (PO4-P, TP, NH4-N, NO2-N, NO3-N, TN), Fe, Mn, heavy metals (Cu, Ni, Cr, Zn, Cd, Pb), total suspended solids (TSS), conductivity, and pH were measured in water samples. Analytical methods commonly accepted in hydrochemical practice were used to determine chemical parameters of the water. The hydrochemical data will enable society to understand the water quality of Lake Onego as it is the main source of freshwater. Therefore, this data can be used for comparative analysis of the hydrochemical characteristics of other large lakes.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.
