Our works:
We deal with experimental studies and theoretical analysis of radiation fluxes in the sea-atmosphere system. Mainly we are interested in inherent and apparent optical properties of seawater components and their influence on solar energy distribution within water body especially the part of energy utilised in primary production process (WoŸniak and Dera 2001).
|
We are able to model main radiant energy fluxes in the sea-atmosphere system (WoŸniak et al. 1996, |
|
|
In the very centre of our concern are complex models of photosynthesis valid for all types of natural water (WoŸniak et al. 1992, Dera 1995,
WoŸniak et al. 1997, WoŸniak and Dera 2000). Such models are elaborated to estimate the primary production quantity by using remote sensing methods and to predict ecosystems functioning (Antal et al. 2001, Ostrowska 2001). In order to develop the models we are investigating and modelling:|
(sea waters classifications for case 1 water and case 2 water by WoŸniak) (WoŸniak and Pelevin 1991, WoŸniak et al. 1995, Kaczmarek and WoŸniak 1995);

|
|
|
(model characteristic of the specific absorption Gaussian bands of pigments) (WoŸniak and Ostrowska, 1990, WoŸniak et al. 1998); (statistical model of marine phytoplankton absorption and fluorescence capacities taking into account acclimation processes, pigment package effects and environmental factor) (Majchrowski and Ostrowska 2000,, WoŸniak et al. 2000, Majchrowski et al. 2000, Ostrowska et al. 2000a,b, Ficek 2001, Majchrowski 2001, Ston et al. 2002, Ston and Kosakowska 2002)

(WoŸniak et al. 1992, WoŸniak et al. 1997, Ficek et al. 2000a,b, Wozniak et al. 2002). |

To achieve these aims we carry out the measurements of light attenuation coefficients, pigments concentration, absorption properties of water seawater components, primary production, fluorescence of phytoplankton photosynthetic apparatus. We have collaborated with scientists from PP Shirshov Institute of Oceanology RAS in Moscow and Department of Biophysics Faculty of Biology Moscow State University (WoŸniak, 1991), and others. Our researches are performed within several international projects, e.g. BALTEX, BIOCOLOR.
