Sediments and sedimentation changes at one station in eastern part of the Kaštela bay

U ovom su diplomskom radu predstavljeni rezultati uzorkovanja A i B jezgre srpanjskog i prosinačkog razdoblja 2012. godine na istočnom dijelu Kaštelanskog zaljeva. Obrađeno je 65 uzoraka sedimenta čime se ustanovilo da na istraživanoj postaji prevladava taloženje čestica veličine silta (51,51± 6,32%) i gline (37,43 ± 7,87%). Prevladavanje vrlo loše sortiranog sedimenta ukazuje na različito podrijetlo (terigeno i biogeno) istaloženih čestica u sedimentu koje su podjednakim udjelom karbonatne i nekarbonatne komponente (49,12 ± 4,86% karbonata). Prema Shepardovoj klasifikaciji najzastupljenija je glinoviti silt, a prema Folkovoj klasifikaciji mulj. Ustanovljene promjene duž jezgara sedimenta, kao i između njih, upućuju na postojanje tri ekološka uvjeta koji upućuju osim na miran okoliš u kojem su povremeno prisutni bentički organizmi i na antropogeni utjecaj s pretaloživanjem sedimenta.The thesis presents the results of A and B core samplings done in the eastern part of Kaštela Bay in July and December 2012. From 65 processed sediment samples it was determined that precipitation of silt particles (51.51 ± 6.32%) and clay particles (37.43 ± 7.87%) prevalied in the examined station. Prevalence of very poorly sorted sediments indicated different origins (terrigenous and biogenic) of precipitated particles in the sediments that are equally made of carbonated and uncarbonated components (49.12 ± 4.86%). According to the Shepard classification, clay silt is most common, and according to Folk classification the most common is mud. The changes along the cores, as well as between them, indicated existence of three ecological conditions what showed not only that there is a stable enviroment where bentic organisms are occasionally found but also an antropological impact with precipitation of sediment
