Systems Analysis of complex glaciological processes and application to calving of Amery Ice Shelf, East Antarctica

Calving is a complex process subject to several cooperating atmospheric, oceanographic and glaciological forcings that vary in space and time, and whose relative effects are challenging to separate. Statistical ‘Systems Analysis’ is commonly used in engineering and economics to extricate complex ‘force–response’ relationships. Here we apply Systems Analysis to the Amery rift system, East Antarc...

A structural glaciological analysis of the 2002 Larsen B ice shelf collapse

This study provides a detailed structural glaciological analysis of changes in surface structures on the Larsen B ice shelf on the Antarctic Peninsula prior to its collapse in February–March 2002. Mapped features include the ice-shelf front, rifts, crevasses, longitudinal linear surface structures and meltwater features. We define domains on the ice shelf related to glacier source areas and dem...

Glaciological and climatic significance of Hercules Dome, Antarctica: An optimal site for deep ice core drilling

[1] We present glaciological and climatological characteristics of Hercules Dome, Antarctica (86 S, 105 W), which demonstrate its potential as a deep ice core site. Annual layering in dD ratios from a 72 m ice core collected by the US-ITASE 2002 traverse indicate accumulation rates of 0.16–0.20 m/yr ice equivalent over the last 300 years. Age control from stratigraphy seen in the radio-echo sou...

GLACIOLOGICAL INVESTIGATIONS OF THE TROPICAL QUELCCAYA ICE CAP, PERU* By LONNIE

Glaciological results of the continuing investigations of the Quelccaya ice cap located at lat. 13 ° 56' S., long. 70° 50 ' W., in the Cordillera Oriental of southern Peru are presented. lee cores to a depth of 15 m have been retrieved from the summit dome (5 650 m), middle dome (5543 m), and south dome (5 480 m) and sampled in detail for microparticle, oxygen-isotope, and total-,8-activity mea...
