A Layered Horizontal Sampler for Shallow Water Bottom Sediment

Abstract

The invention discloses a horizontal layered shallow water bottom mud sampler. The horizontal layered shallow water bottom mud sampler comprises a collector which is used for collecting shallow water bottom mud and a determination device which is used for determining the nutritive salt flux of the shallow water bottom mud. By cooperation of the collector and the determination device, the stirring of a bottom mud-water interface is reduced; the bottom mud, excluding overlying water, is collected, so that the stirring is reduced; a sampling drawer can directly control the layer and thickness of the bottom mud, so that a sample can be collected; the horizontal layered shallow water bottom mud sampler has the advantages of no bottom mud stirring, completeness, clearness in layering and large sampling amount; moreover, a ship does not need to be fixed in a sampling process, and a nutritive salt flux experiment on the bottom mud can be performed in a layered manner; and the horizontal layered shallow water bottom mud sampler is large in experimental flux area, light in weight, simple in structure, convenient to use and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of bottom mud samplers, in particular to a shallow water bottom mud layered horizontal sampler. Background technique [0002] In the process of investigation and research on water ecosystems, it usually involves collecting surface sediment in shallow waters, such as ponds and shallow ocean areas. It is possible to study the flux of nutrients at the sediment-water interface. During the operation, it is required that the collection or experiment should not be disturbed or disturbed as much as possible, and the stratification should be clear and accurate. The mud sample research materials should be as sufficient as possible each time. However, the currently used The mud sampler is bulky in shape, complex in structure, and difficult to carry and operate; when sampling, the sediment-water interface is greatly agitated, or the columnar sampler with less agitation has a limited collection area. Manually suck out t...
