Distribution of the recent planktic foraminifera of bottom sediments at the northeastern Aegean Sea in the Gökçeada-Bozcaada-Çanakkale triangle
(2002) Toker, Vedia; Yildiz, Ayşegul
Mediterranean type 8 species of 4 planktic foraminiferal genera were described in 70 of 100 bottom samples collected from the Gökçeada-Bozcaada-Çanakkale triangle. These species, which show an increase in their abundance and variety depending on depth and temperature of the sea water from Dardanelles to Aegean Sea, are Globigerina bulloides (d'Orbigny), Globigerina falconensis (Blow), Globigerina praebulloides Blow, Globigerinoides ruber (d'Orbigny), Globigerinoides sacculifer (Brady), Globigerinoides trilobus immaturus LeRoy, Globigerinoides trilobus trilobus (Reuss), Neogloboquadrina sp., Orbulina universa d'Orbigny. The specie represent warm and cool waters of the subtropical belt and within the assemblages and proportions of the subtropical-warm water forms are more abundant than the others. In addition, it was observed that the juvenil forms were abundant at the exit of Dardanelles and the number of the adult forms increases towards the Aegean Sea depending on increase in depth and juvenile forms were dominant at the exit of Dardanelles.
