Farinotti, Daniel King, Edward C. Albrecht, Anika Huss, Matthias Gudmundsson, G. Hilmar 2014-07-01 A glacier-wide ice-thickness distribution and bedrock topography is presented for Starbuck Glacier, Antarctic Peninsula. The results are based on 90 km of ground-based radio-echo sounding lines collected during the 2012/13 field season. Cross-validation with ice-thickness measurements provided by NASA's IceBridge project reveals excellent agreement. Glacier-wide estimates are derived using a model that calculates distributed ice thickness, calibrated with the radio-echo soundings. Additional constraints are obtained from in situ ice flow-speed measurements and the surface topography. The results indicate a reverse-sloped bed extending from a riegel occurring ∼5 km upstream of the current grounding line. The deepest parts of the glacier are as much as 500 m below sea level. The calculated total volume of 80.7 ± 7.2 km3 corresponds to an average ice thickness of 312 ± 30 m. application/pdf https://folia.unifr.ch/global/documents/303693 https://folia.unifr.ch/documents/303693/files/hus_bts.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.3189/2014AoG67A025 info:eu-repo/semantics/openAccess License undefined Annals of Glaciology. - 2014, vol. 55, no. 67, p. 22–28 info:eu-repo/classification/udc/556 The bedrock topography of Starbuck Glacier, Antarctic Peninsula, as determined by radio-echo soundings and flow modeling http://purl.org/coar/resource_type/c_6501
