DredgesDredges are placed onto the bottom sediment of still water, then closed and pulled up to retrieve a sample. Careful release of the sample distributes the sample approximately as it appeared on the bottom – making sediment profile description possible. Dredges come if varying sizes and weights depending on the application. Heavy dredges are usually desired for collecting samples in ocean environments where tides may impact the movement of the dredge and also in hard floor lake enviroments that might be diffecult to penetrate the sampling surface.
