Computed tomography (CT) scans of a lake sediment core, Bylot Island, Nunavut, Canada.

Computed tomographic (CT) scanning was used (August 2015) to analyze a 109 cm-long lake sediment core from a thermokarst lake in Bylot Island, Nunavut, Canada. The core was collected in June 2015 at « Gull Lake » (also named BYL-66 in other publications) from the still-present ice cover with a 7 cm-diameter percussion corer (Aquatic Research Instruments). The core was scanned at Centre Eau Terre Environnement of the Institut national de la recherche scientifique (INRS-ETE).
