An ikaite record of late Holocene climate at the Antarctic Peninsula
Calcium carbonate can crystallize in a hydrated form as ikaite at low temperatures. The hydration water in ikaite grown in laboratory experiments records the δ 18O of ambient water, a feature potentially useful for reconstructing δ 18O of local seawater. We report the first downcore δ 18O record of...
