Marine biological elements online monitoring instruments successfully completed standardized sea trials

[ Instrument Network Instrument Development ] Recently, the National Key R&D Program “Animation of Marine Environmental Safety” under the National Key R&D Program of Anguang Institute, “Development and Industrialization of Marine Biochemical Conventional Elements Online Monitoring Instrument”, online monitoring of marine biological elements Significant progress has been made in the application of instruments, and the task of standardized sea trials for the Yellow Sea voyage in 2019 (hereinafter referred to as the “sea test”) was successfully completed.
The project uses optical/spectroscopy as an analytical tool to independently develop seawater chlorophyll online monitor, marine primary productivity online monitor and seawater dissolved oxygen online monitor to realize algae community structure, chlorophyll, primary productivity, dissolved oxygen and other elements. Rapid online and in-situ profile monitoring applications; related equipment and equipment according to the "Marine Instrumentation Equipment Marine Test Management Specification" requirements and sea trial outline tasks, according to the 2019 Yellow Sea voyage plan for on-line navigation, in-situ section observation and comparison Test and other tasks, the cumulative range of 806 nautical miles, 130 hours of online monitoring, 12 in-situ observation points, successfully obtained more than 9,200 data on algal community structure, chlorophyll concentration, primary productivity, dissolved oxygen, and the distribution characteristics of typical sea biological elements. .
The project research and development instrument has the characteristics of rapid and sensitive measurement, no sample pretreatment, pollution-free and non-destructive, and provides advanced means for marine ecological environment quality assessment, fishery resource assessment, and water bloom red tide disaster monitoring and early warning. And effect research, global carbon cycle and climate change prediction have important scientific significance and application value.
The national key research and development plan “Marine Environmental Safety Guarantee” key project “National Marine Equipment Standardized Offshore Test” project “Standard Acoustics and Offshore Marine Ecology Marine Instruments Standardized Offshore Test” project, carefully prepared and powerfully guaranteed, provides a sea test platform And organized experts to carry out the sea test site acceptance.
