Sažetak
The DOM concept has served its purpose in global carbon cycles on oceanic and geological scales [1] and it has been supported by improvements in opperational DOC measurement techniques [2]. However, the DOM concept is questioned, when it comes to a particular process of a new photosynthetic production and DOM fate in a given marine ecosystem. Therefore it is of importance to reconsider and redefine the traditional DOM concept for costal seas. We have selected the case of a most intensive primary production and DOM transformation in a Mediterranean basen, nothern part of the Adriatic Sea, as a possible excersise in validating the DOM concept in view of new instrumental developments [3 and references therein, 4, 5] understandings of microbiological processes [6] and interactions of biopolymers at micro and nanoscales [5, 7].
