| Abstract | In 1983, low-altitude video tapes were made of the coast of Jones Sound; launch surveys were completed off five tidewater glaciers along the northeast coast of Devon Island. Large submarine glacial
deposits off northeast Devon Island suggest that some of the valley glaciers once stood 2 to 7 km off shore for a considerable time before rapidly retreating to near their present position. Today, the proglacial tidewater environments in bays
resemble those of the slowly retreating shallow-water glaciers in Glacier Bay, Alaska. Most of the Devon Island tidewater glaciers are grounded and are fringed by an ice-proximal shelf. Ice-front thickness is commonly 55 to 76 m but at the face of
larger glaciers, it exceeds 100 m. Sediment gravity flows, observed across the ice-proximal shelf foreslope, are an important agent in the transfer and deposition of sediment in the proglacial basins. |
