Khim, B.-K., Yoon, H.I., Kang, C.Y. and Bahk, J.J. 2002. Unstable climate oscillations during the Late Holocene in the Eastern Bransfield Basin, Antarctic Peninsula. Quaternary Research 58: 234-245.
General climatic features were inferred from a study of the grain size, total organic carbon content, biogenic silica content and, most importantly, magnetic susceptibility of 210Pb- and 14C-dated sediments retrieved from the eastern Bransfield Basin (61°58.9'S, 55°57.4'W) just off the northern tip of the Antarctic Peninsula. Most of the Medieval Warm Period (AD 1050-1550) was warmer than the Current Warm Period.
