Reconstrucción de la posición del frente ártico a partir de las asociaciones de foraminíferos planctónicos durante los estadios isotópicos marinos 14, 15 y 16
Planktic foraminifer assemblages and lithic components from IODP core U1314 (northern North Atlantic) were studied with high resolution from marine isotope stage (MIS) 14 to 16 (~ 530-700 ka). This study aims to contribute to a better understanding of the mid-Pleistocene climate shifts. The record s...
