Abstract

U ovom su radu obrađeni podaci o brojnosti i raznolikosti vrsta kokolitoforida, kao i fizikalni i kemijski parametri uzoraka morske vode uzeti na području sjevernog Atlantika na četiri različite postaje u srpnju 2018. s ciljem interpretacije cvata i sastava zajednice kokolitoforida na istraživanom području. Zaključeno je da su se tri postaje nalazile na kontinentskom šelfu, a preostala jedna na kontinentskoj padini. Na postaji na kojoj je zabilježen vrhunac cvata kokolitoforida dominirala je vrsta Gephyrocapsa huxleyi HET uz koju su značajne bile Syracosphaera origami HOL, Syracosphaera corolla HET, Rhabdosphaera xiphos HET i Ophiaster formosus HET.

Abstract (english)

In this paper, data on the abundance and diversity of coccolithophorid species, as well as the physical and chemical parameters of seawater samples taken in the North Atlantic area at four different stations in July 2018, were processed with the aim of interpreting the flora and composition of the coccolithophorid community in the research area. It was concluded that three stations were located on the continental shelf, and the remaining one was on the continental slope. At the station where the peak of the coccolithophorid bloom was recorded, the species Gephyrocapsa huxleyi HET dominated, along with Syracosphaera origami HOL, Syracosphaera corolla HET, Rhabdosphaera xiphos HET and Ophiaster formosus HET.
