Europe’s Grand Canyon: Nazaré Submarine Canyon

The Biogeographic Significance of a Large, Deep Canyon: Grand Canyon of the Colorado River, Southwestern USA

Identification of Temporal Shifting Trends of Submarine Indus Canyon, Pakistan

Indus Canyon is one of the most prominent sub-aqueous features of the Indus Delta. Indus River, originating from the Manasarovour Lake, hosting at the foot of high Himalayan Mountains Glaciers, forms a huge delta after travelling more than 300 km at the north eastern coastline of the Arabian Sea. In view to assess the temporal geomorphic change associated with the Indus Canyon, a study has been...

Sandwave migration in Monterey Submarine Canyon, Central California

Repeated high-resolution multibeam bathymetric surveys from 2002 through 2006 at the head of theMonterey Submarine Canyon reveal a sandwave field along the canyon axis between 20 and 250 m water depth. These sandwaves range in wavelength from 20 to 70 m and 1 to 3 m in height. A quantitative measure was devised to determine the direction of sandwave migration based on the asymmetry of their pro...

Wintertime Boundary Layer Structure in the Grand Canyon

Wintertime temperature profiles in the Grand Canyon exhibit a neutral to isothermal stratification during both daytime and nighttime, with only rare instances of actual temperature inversions. The canyon warms during daytime and cools during nighttime more or less uniformly through the canyon’s entire depth. This weak stability and temperature structure evolution differ from other Rocky Mountai...

Regional economic impacts of Grand Canyon river runners.

Economic impact analysis (EIA) of outdoor recreation can provide critical social information concerning the utilization of natural resources. Outdoor recreation and other non-consumptive uses of resources are viewed as environmentally friendly alternatives to extractive-type industries. While outdoor recreation can be an appropriate use of resources, it generates both beneficial and adverse soc...
