Beaufort Sea Coastal Sediment Study

Chemical analyses of sediments studied to identify meth ods that would simplify analysis of this data. Statistical analysis restricted to observations with grain size results. Relationships between grain size & contaminant concentrations determined. Intra- and inter-laboratory variances noted

A detailed set of wave, current, suspended sediment and pore water pressure measurements was made from August 18 to September 24, 1986 at 2 locations offshore of North Head on Richards Island. Because pack ice remained between 100 and 200 km offshore, 1986 was an excellent year for program and two storms with wave heights up to 2.5 m were monitored in shallow water. The objective was to measure changes in pore water pressure and near-bed suspended sediment concentrations in response to storm generated waves and near bottom currents. Ultimately data are to be used to examine liquefaction potential of surficial soils, expected sediment transport rates and mechanics of wave energy attenuation.
