spatial variation of sediment:

Spatial variations of incoming sediments at the ...

Tow depths of the airguns and streamer cable were relatively shallow (5 m and 6 m, respectively) to better focus on the sedimentary structure. Despite significant differences in the survey configuration, spatial variations in sediment thickness are well constrained by both surveys after applying standard post-stack time migration (Figs. 2 and 3).

2018-2-12 · Ruxi River is a tributary of the Three Gorges Reservoir. This study examined the temporal and spatial dynamics in particle size characteristics and the associated nutrients and contaminants of the fluvial suspended and deposited sediments along the Ruxi River. Temporal variations in the particle size distribution of the suspended sediment are controlled mainly by differences in sediment source ...

In September 2009, a series of sediment cores were collected across the Alaskan Beaufort Sea shelf-slope. Sediment and porewater organic carbon (OC) concentrations and stable carbon isotope ratios (δ13C) were measured to investigate spatial variations in sediment organic matter (OM) sources and distribution of these materials across the shelf.
