We present high-resolution benthic delta C-13 records from intermediate water depth core site MD01-2461 ( 1153 m water depth), from the Porcupine Seabight, NE Atlantic, spanning 43 to 8 kyr B. P. At an average proxy time step of 160 +/- 56 years this core provides information on the linkage between...
