Hydrochemical Methods of the Bioproductivity Assessment in Fishing Grounds of the World Ocean

Abstract

The article presents not only theoretical background for the primary production (PP) assessment based on hydrochemical indices, but also numerous examples of the PP assessment for polar waters, upwelling zones, and ultraoligotrophic tropical waters. All advantages of the PP assessment based on hydrochemical parameters are shown, including a better representation and a more thorough assessment of PP in the Wordld ocean.
