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...

| Sumario: | 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 shows the evolution of the Arctic front and allows us to infer the relative position of the sea-ice edge. During MIS 16 Arctic front was south of the core location, while during MIS 14 the front was placed northward but near the core location, therefore stage 16 was colder than 14. Besides, during the interglacial stage 15, two brief cold substages were recorded showing that the Arctic front crossed again the core location area |
