Visible Fidelity Collector of a Zooplankton Sample from the Near-Bottom of the Deep Sea

The multi-net visible fidelity zooplankton collector is designed to obtain near-bottom fidelity zooplankton. The collector is sent to the designated sampling location based on the information provided by the camera and altimeter. The host computer sends instructions to control the opening of the net port for sample collection and closing of the sampling cylinder cover after sampling. The collector contains three trawls so that three samples can be collected for each test, and environmental parameters can be collected simultaneously. After sampling, The sample maintains its fidelity, that is, maintaining the temperature and pressure of the seabed sample after sampling. Two experiments were carried out in the Western Pacific, and six bottles of zooplankton samples were successfully obtained. The development of a multi-net visible zooplankton collector is of great significance for the collection of near-bottom zooplankton.

Automated summary

The multi-net visible fidelity zooplankton collector is designed to obtain near-bottom zooplankton with high fidelity. It has been proven effective through multiple experiments and provides an important reference for the collection of near-bottom zooplankton.
