Ice Thickness from downstream of the EastGRIP ice core site, North East Greenland Ice Stream, recorded with the airborne AWI UWB radar system ...

This project aims to acquire airborne data with AWI's UWB (ultrawideband) ice-penetrating radar to extend the knowledge of detailed subglacial topography downstream of the EastGRIP ice core site, following on from a previous UWB radar survey in 2018. The ice thickness data also opportunisticall...

Description
Summary:This project aims to acquire airborne data with AWI's UWB (ultrawideband) ice-penetrating radar to extend the knowledge of detailed subglacial topography downstream of the EastGRIP ice core site, following on from a previous UWB radar survey in 2018. The ice thickness data also opportunistically includes profiles that were flown in different survey modes, both upstream and surrounding EastGRIP. The majority of profiles are oriented parallel or perpendicular to ice flow direction. ... : AWI Flight Campaign: P5-233_NEGIS_2022Project: EGRIP-NOR-2022Region: Greenland, North East Greenland Ice StreamOwner / PI: Olaf Eisen (AWI)-Email address of the provider:olaf.eisen@awi.decharlotte.carter@awi.de-Instrument used: AWI UWB (MCorRDS 5)Firn correction: None appliedVelocity profile: dielectric constant of 3.15 ( c = 1.68914e8 m/s )Ice thickness uncertainty:Calculated as the RMS of the the sum of the crossover mean of 3639 intersections (12.23 m)and the error of the dielectric constant (1%).sqrt( (crossover_mean)^2 + ( (-ice_thickness/2) * 0.01 )^2 )-Method of navigation : GPS data was acquired by four NovAtel DL-V3 GPS receivers operating at 20Hz ...
