ABSTRACT / SAŽETAK:
Nutrijenti predstavljaju ključne indikatore eutrofikacije u morskim ekosistemima. U radu je analizirana vertikalna raspodjela nutrijenata u vodenom stubu na više lokacija duž crnogorske obale. Uzorci morske vode prikupljeni su na različitim dubinama (0 m, 5 m, 10 m i pridneni sloj), a analizirane su koncentracije azotnih i fosfornih jedinjenja. Rezultati pokazuju izražene promjene koncentracija sa dubinom. Niže vrijednosti uglavnom su zabilježene u površinskim slojevima, dok su više koncentracije najčešće prisutne u dubljim slojevima. Ovakav obrazac ukazuje na biološku potrošnju nutrijenata u površinskim vodama i procese remineralizacije organske materije i regeneracije nutrijenata u dubljim slojevima vodenog stuba.
