The Foreslope Hills are a series of ridges and troughs covering over 60 km2 of the sea floor at the base of the Fraser Delta slope. Internally, the hills consist of blocks of prodelta and delta slope sediment (> 10.6 km3) bounded by offshore dipping faults and shear pla...

Abstract Anthropogenic modification of forests has often decoupled streams from riparian ecosystems and altered natural wood recruitment processes. Extensive research has shown that large wood significantly impacts channel dynamics, especially in small and intermediate ...

An analysis of current meter and hydrographic data collected from an array of moorings situated at the shelf break off Nova Scotia is presented. In particular, the focus is on the ocean response to moderate (10 to 20 m s-1), transient winds of two or more days duration ...

Lake waters are a useful area for investigating the response of the Earth¡¦s gravity field to topographical density variations, since lake beds represent large density contrasts between water and rock. However, our ability to investigate relations between lake bathymetr...

Widespread glacier acceleration has been observed in Greenland in the past few years. Oceanographic observations taken in summer 2008 show that ocean waters melted a substantial fraction of ice along the calving fronts of three West Greenland glaciers, indicating that s...

Abstract In April 2000 a large-scale rock avalanche dammed the Yigong Zangpo River, forming an extensive rockslide-dammed lake. The impoundment lasted for 62 days before a catastrophic breaching caused a massive outburst flood in the Yarlung Zangpo (Tibet) and the Dihan...

The geomorphology of troughs crossing the Antarctic shelf is described and interpreted in terms of ice-stream hydrology. The scale of tunnel channels on the inner shelf and the absence of sediment at their mouths are taken to infer catastrophic drainage. Drumlins on the...

Abstract Observations from high resolution bathymetric surveys on the coast of North Carolina indicate areas with shore-parallel depth contours and other areas with shore-oblique sandbars. These shore-oblique bars are large-scale morphological features that extend up to...

Abstract This investigation explores the at-a-station hydraulic geometry (AHG) of small, steep mountain streams at low discharge. Thirteen reaches in five tributaries of Chilliwack River, British Columbia, ranging in size from 12 to 77 km 2 are examined. The resulting d...

Les fèces d’animaux d’élevage et les effluents d’origine urbaine ou agricole sont les principales sources de contamination microbiologique participant à la dégradation de la qualité des eaux et des coquillages et à l’apport de pathogènes entériques dans l’environnement....
