resuspension

The EPA also wants to cut down on the level of PCBs kicked up from dredging, setting new standards on "resuspension" to limit wildlife exposure.

Also, the federal agency's thresholds for PCB "resuspension" in the water were exceeded twice, causing a temporary shutdown of work in August and a partial shutdown in September.

Similarly, reduced sea ice is likely to change the early spring ecosystem processes but greater surface exposure to winter storm conditions is likely to increase nutrient cycling and resuspension from shallower waters.

Similarly, loss of sea ice may result in changes to the early spring bloom and associated ecosystem processes, however greater surface exposure to winter storm conditions might increase nutrient circulation and resuspension in shallower waters.

In addition, increased freshwater input is likely to deposit more organic material, changing estuarine biogeochemistry and perhaps increasing primary productivity, the positive effects of which will possibly be offset in part by increased resuspension of contaminated sediments in these systems.

Effects of climate change on general hydro-ecology in the Arctic

Sea-ice pressure-ridge keels and icebergs scour the seabed, resulting in a characteristic roughened or ploughed seabed morphology that may affect resuspension rates and could change the degree of consolidation of the seabed surface.

As for indoor-air quality, the authors contend that central-air systems "increase air velocities and resuspension of particulate matter" and reduce fresh-air introduction, since "windows that would otherwise be open in the warm months are more likely to be kept closed in the presence of central air conditioning."

Seagrass stabilize sediments, diminishing sediment resuspension while promoting sedimentation.

This biologically induced roughness modifies the hydrodynamics above the sediment layer, which in turn affects erosion and resuspension.

Turbulent flow conditions are absolutely necessary for resuspension and transport of the accumulated solids through the filter.
