Abstract
Niveo-aeolian processes refer to the combined effect of blowing sand and snow in a coastal dune system. The dune system at Pinery Provincial Park is made up of shore parallel foredunes fronting complex parabolic dunes and trough blowouts. A marked seasonality exists in the transport of sand through these features. Winter sediment transport is significant, moving through the dunes at a time when sand trapping vegetation is dormant. The purpose of this paper is to document the presence and quantity of blowing sand deposited with snow on the backside of the dune. Volumes of sand deposited in the snow were estimated by snow coring to make point estimates of sand volume. These estimates were overlaid on a map and the volumes on a surface were approximated. The conclusions of the research indicate that: a significant volume of sand is transported with snow through the dune system in winter; there are large volumes of sand transported even though the surface is frozen or nearly completely covered with snow; and, cold regions processes are important in the dunescape of this northern extension of the Carolinian Zone.
