    Holocene glacier behavior around the northern Antarctic Peninsula and possible causes
    (2020) Kaplan, M. R.; Strelin, J. A.; Schaefer, J. M.; Peltier, C.; Martini, M. A.; Flores, E.; Winckler, G.; Schwartz, R.
    We obtained 49 new Be-10 ages that document the activity of the former Northern Antarctic Peninsula Ice Sheet, and subsequently the James Ross Island Ice Cap and nearby glaciers, from the end of the last glacial period until the last similar to 100 years. The data indicate that from >11 to similar to 8 ka marked recession of glacier systems occurred around James Ross Island, including tidewater and local land-terminating glaciers. Glaciers reached heads of bays and fjords by 8-7 ka. Subsequently, local glaciers were larger than present around (at least) 7.5-7 ka and similar to 5-4 ka, at times between 3.9 and 3.6 ka and just after 3 ka, between similar to 2.4 and similar to 1 ka, and from similar to 300 to similar to 100 years ago. After deglaciation, the largest local glacier extents occurred between similar to 7 ka and similar to 4 ka.
