Knowledge about macrotidal tidal flats comes mainly from studies in temperate regions, but the inclusion of sea ice in the Arctic means things look and behave differently. A better understanding of Arctic tidal flats may help communities adapt to projected changes. This study builds on past work that described the morphology and dynamics of the Iqaluit tidal flats, in an area of 12 m tidal range at Iqaluit, Baffin Island. We undertook field surveys and instrument moorings in summer and winter over 3 years (2009-2011). The Iqaluit waterfront is formed by storm beaches fronted by wide intertidal mud and sand boulder flats underlain by glaciomarine clay-silt sediments. It appears that the flats are being actively eroded by a number of processes, including ice push and rafting, tidal currents, surface runoff, and submarine slumping along the edge of the flats. gccst Erosion gccst Sedimentology gccst Geophysics Forbes, D.
