Summary(Plain Language Summary, not published)
A series of sediment cores was collected in Lancaster Sound during the Geological Survey of Canada ¿ Atlantic (GSCA) cruise 2008-029 onboard the CCGS Hudson. The cores from cruise 2008-029 have the most modern and complete suite of geotechnical and sedimentological analyses for any sediment samples in the Lancaster Sound region. The purpose of this report is to make these data available and provide a regional overview of sediment characteristics and basic geotechnical properties in Lancaster Sound. The lowermost sediment penetrated by these cores is the Baffin Shelf Drift unit. This till is a very dark brown sandy clay with sandy laminations and pebbles. The till is overlain by Davis Strait Silt unit laminated glaciomarine sediments consisting of carbonate-rich gray silty clay with occasional sandy layers and pebbles. The uppermost sedimentary unit is comprised of the post-glacial bioturbated olive gray silty clay of the Tikitartuq Mud unit.
