metadata.name: dc.description.abstract
metadata.value: This study provides a rather new approach to research on a portion of general
  biological production of marine ecosystems, namely on primary production.
  The methodology presented consists of two blocks of techniques. The hydrological
  block provides for an estimate of the amounts of basic water masses, the
  estimate being based on the salinity and δ18O stable isotope value. The techniques
  of the ecosystem block provide for a calculation of primary production
  based on the water mass composition, nutrients concentrations in the cores
  of the water masses, and changes in nutrients reserves. The rate of the nutrients
  reserve change is corrected by the non-productive component caused by
  the inflow or outflow of the nutrient as a result of advection or exchange with
  underlying layers. Another correction is related to nutrient regeneration going
  in parallel to photosynthesis. The technique was tested and verified in the waters
  around the Svalbard archipelago. By using a combination of δ18О isotope
  parameter (with an intention to add δ2H in the future), salinity, and nutrients
  composition, the present methodology allows to consider the domain of the
  marine ecosystem comprising its hydrological, hydrochemical, and hydrobiological
  (phytoplankton) processes as a single system of their relationships.
