An extensive ice sheet builds up during the winter in a salt marsh complex at the mouth of Eagle River near Anchorage, Alaska. To clarify how snow accumulation, periodic tidal flooding, and freshwater flow contribute to the ice cover, ice cores were taken along a transect beginning at a deep pond along the edge of the salt marsh and transversing marsh, shallow pond, and mudflat areas. Ice structure, ice salinity, ice thickness, and the or absence of sediment bands in the ice are described and were found to change markedly along the transect.
