Abstract
Measurements made in a Spartina alterniflora tidal marsh along the St. Lawrence Estuary provide a rough estimate of the role of shore ice in tidal marsh development in a periglacial region. Marsh clumps torn out and moved by ice floes and subsequently released throughout the marsh surface give a minimum value for the volume of debris removed annually by ice. In nine sample plots surveyed at Isle-Verte, clumps released in the marsh by ice floes upon melting cover 0.9 to 16.5% of the area investigated, whereas the volume of clumps ranges from 1.9 to 99.6 cubic meters. Ice-borne clumps represent an important component of the sedimentary budget.
