Benthic foraminiferal distribution and taxonomy in the continental shelf of Goekceada, Bozcaada and Canakkale triangle (NE Aegean Sea)

The faunal composition and taxonomic distribution of benthic foraminifera in the Goekceada-Bozcaada-Canakkale triangle were investigated on the basis of 31 surface sediment samples. These are characterized by the lithologies of gravel, sand and mud. A total of 160 species belonging to 43 families an...

Summary:The faunal composition and taxonomic distribution of benthic foraminifera in the Goekceada-Bozcaada-Canakkale triangle were investigated on the basis of 31 surface sediment samples. These are characterized by the lithologies of gravel, sand and mud. A total of 160 species belonging to 43 families and 84 genera were determined from these samples. The agglutinated species are abundant, but never reach dominant number; however, calcareous forms have eight benthic species which are dominant number. These are respectively; Ammonia compacta Hofker, Asterigerinata mamilla (Williamson), Brizalina spathulata (Williamson), Cassidulina carinata Silvestri, Elphidium crispum (Linne), Porosononion subgranosum (Egger), Rosalina bradyi Cushman and Valvulineria bradyana (Fornasini). The relationships between the dominant species, lithology and CaCO sub(3) concentration were also investigated.Original Abstract: Bu calismada, Goekceada-Bozcaada ve Canakkale Bogazi arasinda kalan boelgedeki bentik foraminiferlerin faunal bilesimi ve taksonomik dagilimlari incelenmistir. Boelgeden 31 adet dip sediman oernegi toplanmistir. Bu oernekler genel olarak camur, kum ve cakil litolojileriyle temsil edilmektedir. Boelgede toplam 43 familyaya ait, 84 cins ve 160 tuer tayin edilmistir. Tanimlanan foraminiferlerden aglutinant kavkili olanlari baskin sayiya erisemezlerken, kalker kavkili olanlardan sekiz tueruen egemen tuer oldugu saptanmistir. Bunlar sirasiyla; Ammonia compacta Hofker, Asterigerinata mamilla (Williamson), Brizalina spathulata (Williamson), Cassidulina carinata Silvestri, Elphidium crispum (Linne), Porosononion subgranosum (Egger), Rosalina bradyi Cushman ve Valvulineria bradyana (Fornasini)'dir. Ayrica; litoloji, CaCO sub(3) konsantrasyonu ve egemen tuerler arasindaki iliskiler incelenmistir.
