title: CLIMATIC FLUCTUATIONS IN THE MIDDLE LATITUDES OF THE NORTHERN HEMISPHERE ACCORDING TO THE STUDY OF CAMPANIAN PLANKTONIC FORAMINIFERA
abstract: To reconstruct the climatic fluctuations that occurred in the middle latitudes of the Northern Hemisphere in the Atlantic Ocean in the Campanian Age, the systematic composition of the shells of planktonic foraminifera was studied from core samples from seven deep-water drilling holes. The identified foraminiferal assemblages are assigned to two types (boreal and intermediate) and one subtype (warm boreal) thanatocenosis. On the basis of their spatial distribution, the position of climatic zones
