Remote determination of temperature and salinity in presence of dissolved organic matter in natural waters using laser spectroscopy

Abstract
During the last years, the problem of remote determination of parameters of natural waters became very important. This is due to the fact that salinity and temperature are the key parameters determining ocean circulation, and transfer of energy and mass in conterminous layers of the ocean. The authors of this study have previously suggested and implemented a method of simultaneous determination of temperature and salinity of seawater using laser Raman spectroscopy. In this paper, the results of the next step of this work are presented: the determination of temperature and salinity of natural water using Raman spectra in presence of fluorescence of dissolved organic matter as dispersant pedestal under the Raman valence band. This inverse problem of laser spectroscopy was successfully solved using Raman and fluorescence spectra of aqueous media and using artificial neural networks.
