<i>In situ</i> and <i>simulated in situ</i> primary production in the Gulf of Gdañsk
Abstract
The method discussed in this article allows the simulated in situ primary production in the southern Baltic to be evaluated. To estimate the daily primary production at a~given field station, the following parameters have to be measured: the coefficients AN and Es (constants from the photosynthesis-light curve for phytoplankton), and the scalar irradiance attenuation coefficient (k), chlorophyll a concentration (Chl) and daily irradiation just below the sea surface (PAR). The results of simulated in situ primary production are in good agreement with the in situ measurements.
