Abstract

Primarna proizvodnja proces je iskorištavanja anorganskog ugljika u organski oblik tijekom fotosinteze. Morski fitoplanktonski organizmi najbrojniji su autotrofi na svijetu te su odgovorni za polovinu primarne proizvodnje u svijetu. Jadransko more jedinstven je morski bazen smješten u istočnom Sredozemnom moru. Prema geografskim, hidrološkim i biološkim karakteristikama, njegova najuobičajenija podjela je na sjeverni, srednji i južni Jadran. Na produktivnost Jadrana velik utjecaj imaju rijeke, od kojih je najveća rijeka Po u sjevernom te Zrmanja i Krka u srednjem dijelu. Na miješanja vodenih masa u Jadranu najveći utjecaj ima termohalina cirkulacija. Ogranak Levantinske intermedijarne vode zimi utječe u Jadran i kreće se uz njegovu istočnu obalu, dok se ljeti voda iz Jadrana kreće uz njegovu zapadnu obalu i istječe u Sredozemlje kroz Otrantska vrata. Veliko područje povećane primarne proizvodnje u Jadranskom moru sjeverni je Jadran zbog iznimnog utjecaja talijanske rijeke Po, ali i određene točke u području Palagruškog praga u južnom dijelu bazena. Obala otoka Lastova područje je povećane primarne proizvodnje zbog specifičnog fenomena valova vezanih uz otok koji se počeo aktivnije istraživati. Srednji Jadran jedina je regija koja je kontinuirano promatrana. Postoji potreba za izradom standardiziranog protokola mjerenja primarne proizvodnje i budućih istraživanja, osobito zbog klimatskih promjena.

Abstract (english)

Primary production is utilizing inorganic carbon into organic form via photosynthesis. Marine phytoplankton organisms are responsible for almost half of the primary production worldwide. The Adriatic Sea is a unique sea basin located in the eastern Mediterranean Sea. It is usually divided into the northern, middle and southern region. The thermohaline circulation is the most important for mixing different water masses in the Adriatic. During winter, the water mass from Mediterranean flows into the Adriatic, while in summer the water from the Adriatic flows into the Mediterranean. A large region of increased primary production in the Adriatic Sea is definitely the northern Adriatic, due to the significant influence of the Italian Po River. There are certain hotspots of primary production in the area of the Palagruški Prag in the southern part of the basin. The Lastovo island is characterised with unique phenomenon of Island Trapped Waves which is associated with increased primary production. The Central Adriatic is primarily influenced by antrophogenic eutrophication and rivers Zrmanja and Krka. It is the only region that has been continuously observed. There is a need to create a standardized protocol for measuring primary production and future research, especially due to climate change.
