UK Polar Data Centre, Natural Environment Research Council, UK Research & Innovation. https://doi.org/10.5285/8ac60c79-d768-4ee1-969f-cce671824085 During the austral summer of 2001/02 five thousand line kilometres of airborne radio echo sounding and aeromagnetic data were collected in the region of three tributaries of Slessor Glacier, East Antarctica, which drains into the Filchner Ice Shelf. We present here the processed line aeromagnetic data acquired using scintrex cesium magnetometers mounted on the BAS aerogeophysical equipped Twin Otter. Data are provided as XYZ ASCII line data. Data were colected as part of UK Natural Environment Research Council (NERC) grant GR3/AFI2/65 No credit. completed Ferraccioli, Fausto British Antarctic Survey Researcher author Bamber, Jonathan University of Bristol Researcher author Joughin, Ian University of Washington Researcher author Shepherd, Tony University of Bristol Researcher author Rippin, David University of Leeds Researcher author Siegert, Martin Bristol Glaciology Centre, University of Bristol Researcher author Vaughan, David British Antarctic Survey Researcher author NERC EDS UK Polar Data Centre +44 (0)1223 221400 British Antarctic Survey, High Cross, Madingley Road Cambridge Cambridgeshire CB3 0ET United Kingdom PDCServiceDesk@bas.ac.uk https://www.bas.ac.uk/team/business-teams/information-services/uk-polar-data-centre/ information pointOfContact asNeeded completed EARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic Anomalies theme Global Change Master Directory (GCMD) Science Keywords 2026-01-27 publication 23 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) Greenbelt MD United States of America https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

(2006) along with further details on survey design and processing. Data available here includes all channels from raw through to microlevelled, products. Channel naming follows SCAR/ADMAP2 data release protocols, although the order of processing steps differs from that outlined by ADMAP2 documentation. Note in the database split by line the sections are defined as follows L= main survey grid lines, T=main survey tie lines, S=long transits, D=turns, P=Line sections between turns. Magnetic data channels and processing flow: Note that CLAFI processing work flow is ordered differently to ADMAP2 protocols, but naming conventions, compensations and corrections are adhered to. MagR- Raw magnetic total field intensity data (nT). TCorr- Tiptank corrections (nT). These include DC shifts and gradients due to aircraft noice, etc. Dummy values if not applicable. MagTCorr- Raw magnetic data corrected/cleaned for obvious tip tank events or anomalous spikes (nT). MagTC- Raw magnetic data corrected for tiptank events and low pass filtered at a cutoff wavelength of 5 fiducials to account for noise introduced by aircraft roll, pitch and yaw. (nT) Filtering applied instead of a designated compensation. BCorr- Low pass filtered (10 minute) magnetic base station correction. MagBTC- Filtered magnetic data corrected for tiptank events and base station measured geomagnetic field variations. (nT) MagBTC= MagTC- BCorr RefField- Geomagnetic reference field value for which the magnetic data has been compensated. IGRF model 2000 as implemented in Geosoft (nT). MagBRTC- Filtered magnetic value adjusted for tip tank, base station and the geomagnetic reference field variability. (nT) MagBRTC= MagBTC- RefField. ACorr- Additional correction applied to compensate for heading errors. SCorr- Any DC shift applied. MagF- Final mag value before levelling. (nT) MagL- Statistically levelled mag data. (nT) MagML- Microlevelled magnetic data following technique of (Ferraccioli et al., 1998). (nT) Note tie lines are not included in the microlevelled data channel.
