Zeising, Ole; Eisen, Olaf; Hofstede, Coen Matthijs; Brisbourne, Alex; Anandakrishnan, Sridhar: Vibroseismic measurements on Thwaites Glacier, Antarctica from 2023/24 [dataset bundled publication]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.987693 (dataset in review)
Abstract:
This vibroseismic survey was conducted on Thwaites Glacier in West Antarctica in 2023/24, as part of the International Thwaites Glacier Collaboration's project GHOST (Geophysical Habitat of Subglacial Thwaites). The 134 km long seismic profile (section 20240551) was measured perpendicular to the flow direction. This bundle contains datasets of the vibroseismic raw data, stacked and Kirchhoff migrated profiles, and seismic attributes in addition to metadata.
