 waters of the western Champlain Sea\n\nRésumé / abstract:\n\nGlaciomarine 
 Champlain Sea (CS) sediments form a regional aquitard in the Ottawa valley
  and St. Lawrence lowlands with potential for landslide development. This 
 presentation will summarize results and insights from Geological Survey of
  Canada (GSC) and partner investigations of CS sediments in the Ottawa val
 ley. In 2019\, the GSC obtained near-continuous cores from deep boreholes 
 drilled at two sites in suburban Ottawa (49 and 66 m depths). Studies of t
 he boreholes\, core sediments and pore waters include a range of interdisc
 iplinary geoscientific methods\, namely\, pore water geochemistry and isot
 opes\, exchangeable cation chemistry\, bulk sediment geochemistry\, physic
 al and geotechnical properties\, borehole geophysics\, mineral magnetism\,
  CT (computed tomography) scans\, optical microscopy\, SEM (scanning elect
 ron microscopy)\, EDS (energy dispersive X-ray spectroscopy)\, XRD (X-ray 
 diffraction)\, hydraulic head\, pollen counts\, and microfossil enumeratio
 ns and their isotopic compositions.\n
