Solar forcing and El Niño-Southern Oscillation (ENSO) influences on productivity cycles interpreted from a late-Holocene high-resolution marine sediment record, Adélie Drift, East Antarctic Margin
Abstract Core JPC17B was collected from the Adélie-Drift, a nearly 300-m thick drift deposit at 140ºE along the Indian Ocean sector of the Antarctic continental shelf. Sediments consist of nearly continuously laminated diatom mud and diatom ooze, with accumulation rates on the order of 20-21 m kyr-1...
