Sailing type plankton online collection device

Abstract

The invention belongs to the technical field of marine survey field measurement and sampling tool manufacturing, and particularly relates to a sailing type plankton online collection device. The sailing type plankton online collection device comprises a seawater sample injector, a sampling net and a sample collection bag which are sequentially connected, wherein the outer sides of the sampling netand the sample collection bag are sleeved with a protective cover; the protective cover is a hollow cylindrical frame; a mini CTD is arranged on the protective cover; and a flowmeter is arranged in the sampling net. The sampling net is of a conical structure which is gradually thinned from the sample injection end to the tail. The sailing type plankton online collection device is applied to the aspect of marine plankton collection, the problems that a collector cannot be operated online in real time, the sampling water filtering amount cannot be measured, equipment is difficult to disassembleand assemble due to the fact that the overall structure is of a barrel type structure, and plankton sample recycling is troublesome are solved, and the sailing type plankton online collection devicehas the advantages of being light in structure, convenient to disassemble and assemble, capable of measuring the sampling water filtering amount and capable of obtaining environment parameters onlinein real time.

Description

technical field [0001] The invention belongs to the technical field of on-site measurement and sampling equipment manufacturing for marine surveys, and in particular relates to a mobile plankton online collection device. Background technique [0002] Plankton is an important basic link in the ecosystem. The changes in the composition and quantity of the population reflect the dynamics of the entire ecosystem and also affect the biogeochemical cycle of the source elements. In particular, a few key species play a role in controlling the overall situation. effect. Zooplankton plays a central role in the marine food chain. Most zooplankton feed on phytoplankton, and they themselves are the bait for fish and other advanced feeders. An important part of. Therefore, it is of great significance to accurately determine the population structure and distribution pattern of plankton. However, during the sailing process, the seawater flow rate is relatively fast, and the general ship ...
