Experiments on transitional regime sediment density flows and resulting deposits
Much remains unknown regarding the sedimentary deposits of submarine density flows. Certain density flows may transition from a more turbulent to a more coherent flow regime e.g. by a loss of velocity in flows with large concentrations of suspended sediment. Such transitional flows are produced …

Remote estimation of aquatic sediment density in the presence of scatter.
… method is tested for its ability to estimate the density of the first few meters of shallow marine sediment. Normal incidence reflections from a 16 kHz omnidirectional source are collected using a single hydrophone directly above the source. An empirical relationship is then used to estimate the …

Analysis of laminated sediments from Lake DV09, northern Devon Island, Nunavut, Canada
A 147cm sediment core from Lake DV09, northern Devon Island, Nunavut, Canada (75° 34'34"N, 89° 18'55"W) contains annually-laminated (varved) sediments, providing a 1600-year record of climate variability. A minerogenic lamina deposited during the annual thaw period and a thin deposit of …

Experimental study of reservoir turbidity currents venting
… of their performance is threatened by sediment deposition within the impoundment. To achieve long-term sustainable performance of reservoirs, and to reach effective sediment management techniques, it is necessary to understand the characteristics of sediment and how it behaves before, …
