Isotopic variations reflected the dynamic nature of carbon input to continental shelf environments, which are influenced by phytoplankton blooms in spring and summer, and allochthonous (terrigenous) inputs in winter. The 13Corg isotopic composition of organic matter in surficial sediments suggests that the settling organic matter source was largely phytoplanktonic (marine)V Lyonskem zalivu (Z Sredozemsko morje) smo določili izotopsko sestavo ogljika v sedimentirajoči organski snovi. Ugotovljene sezonske variacije odražajo spremenljive razmere, ki so posledica cvetenja fitoplanktona v pomladnem in poletnem obdobju ter kopenskega (terigenega) vnosa pozimi. Sedimentirajoči organski delci so pretežno fitoplanktonskega (morskega) izvora, kar se odraža tudi v izotopski sestavi 13C v površinskih sedimentihTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Naravoslovnotehniška fakulteta
