“…Both types are expected to behave differently under climate variations. Because the calving front is more dynamically active, the data set has been supplemented with the results of several earlier studies [Carbonnel and Bauer, 1968;Weidick, 1991;Fastook et al, 1995; Krabill et al, 1995], available topographic maps, and additional SAR observations. These data were coregistered to the image data using a polynomial rectification technique.…”

Little Ice Age advance and retreat of Glaciar Jorge Montt, Chilean Patagonia

Abstract. Glaciar Jorge Montt (48 • 20 S/73• 30 W), one of the main tidewater glaciers of the Southern Patagonian Icefield (SPI), has experienced the greatest terminal retreat observed in Patagonia during the past century, with a recession of 19.5 km between 1898 and 2011. This retreat has revealed trees laying subglacially until 2003. These trees were dated using radiocarbon, yielding burial ages between 460 and 250 cal yrs BP. The presence of old growth forest during those dates indicates that Glaciar Jorge Montt was upvalley of its present position before the commonly recognized Little Ice Age (LIA) period in Patagonia. The post-LIA retreat was most likely triggered by climatically induced changes during the 20th century; however, Glaciar Jorge Montt has responded more dramatically than its neighbours. The retreat of Jorge Montt opened a 19.5 km long fjord since 1898, which reaches depths in excess of 390 m. The bathymetry is well correlated with glacier retreat rates, suggesting that dynamic responses of the glacier are at least partially connected to near buoyancy conditions at the ice front, resulting in high calving fluxes, accelerating thinning rates and rapid ice velocities.
