AI Technical Summary

Technical Problem

Existing technologies cannot fully reflect the dynamics of CO2 exchange among large algae, marine shellfish, and algae in the natural environment, and the experimental devices cannot simulate real field environments, which limits the reliability and applicability of the experimental results.

Method used

Design an experimental device comprising a stabilizing component, an enclosure component, and a collection device. The device is fixed in a marine aquaculture area and stabilized using a float and anchors. The collection component collects shed aquatic organisms. The collection device and a monitoring instrument measure CO2 content in real time. The sealing cap design ensures the gas collection is airtight. The connecting components and support rods facilitate installation and adjustment.

Benefits of technology

It enables dynamic monitoring of carbon sinks in shellfish and algae, improves the reliability of carbon exchange data at the air-sea interface, and simultaneously acquires dissolved organic carbon and inert organic carbon indices, making up for the limitations of traditional methods. The device has a stable structure and is easy to operate.

Abstract

This invention provides an enclosure experimental device and method for measuring carbon sequestration in shellfish and algae, comprising: a stabilizing component, an enclosure component, a collection component, and a collection device; the stabilizing component is fixed on a marine aquaculture area, and multiple enclosure components are arranged inside the stabilizing component, each enclosure component containing a collection component for collecting shed material from aquaculture organisms; the collection device is mounted on the stabilizing component, with its lower end positioned above the collection component, and its upper end connected to a monitoring instrument via an air tube, the monitoring instrument being configured to measure the CO2 content of the air above the collection device. This invention can simulate a real marine aquaculture environment, enabling better collection of biological shed material and gas data, and improving the accuracy and scientific rigor of carbon sequestration measurement.
