Description
Technical Field
The invention relates to the technical field of sea gas observation, in particular to a sea gas carbon flux observation buoy and a working method thereof.
Background
Since 1960, global CO 2 The concentration increased from 280ppm to 410ppm, and the united states inter-government climate change committee (Intergovernmental Panel on Climate Change, IPCC) indicated "the next 20 years will be at a temperature of 1.5 degrees celsius". Climate change is a major problem concerning human survival and development in various countries, and is one of the most serious challenges facing humans in the 21 st century.
The ocean is used as the largest carbon reservoir on the earth, can continuously absorb and fixedly convert carbon dioxide in the atmosphere, and can reduce CO in the atmosphere 2 Content and stable climate change have a prominent contribution. In the vertical direction, CO in the atmosphere 2 Is transferred to the ocean by sea-gas interaction, dissolved CO in the ocean 2 Is immobilized in the ocean by biological absorption and sedimentation, and the total amount of carbon passing through unit area in unit time in the vertical direction is defined as carbon flux, and the carbon flux can be used for quantifying the absorption of atmospheric CO by the ocean 2 And (3) assessing the carbon sequestration capacity of the ocean.
At present, the observation method of ocean carbon flux mainly comprises remote sensing, a box method, a direct measurement method and the like, and the remote sensing observation method is used for observing atmospheric CO 2 The change of the content is used for calculating the carbon flux, and the ocean CO can not be directly observed 2 Content and observation are easily affected by weather; the box method observation precision is greatly influenced by a measuring instrument, the measuring range is small, and the system error is large; direct measurement cannot be used for long-term in situ carbon flux observation. Therefore, the conventional ocean carbon flux observation equipment cannot realize long-term in-situ, high-resolution and carbon flux observation between the vertical interfaces of the sea and the gas.
Currently, observation devices for carbon flux focus mainly on carbon flux measurements between the atmosphere and the soil and between the atmosphere and the water meter layer. As disclosed in CN104535522A, the invention is named as a wet land CO in intertidal zone 2 Flux measuring device and measuring method thereof, discloses a tidal zone wetland CO 2 Flux measuring device and measuring method thereof, and infrared gas analyzer is adopted to measure CO in carbon flux gas chamber 2 The change of concentration with time gives a flux of carbon dioxide between the atmosphere and the intertidal zone wetland. However, the device only measures the carbon flux in the closed air chamber, and the carbon flux in the environment is changed for a long time, so that the device ignores the interference of the external environment and has a certain limitation. The invention discloses a real-time sea-air coupling observation buoy system based on Beidou iridium double-star communication, which has the publication number of CN110203333A and is characterized in that turbulence pulsation signals are measured by adopting a vortex correlation method flux measurement module to calculate CO 2 Covariance of concentration pulsation and vertical wind speed pulsation to obtain CO 2 Flux. However, the device only measures the carbon flux between the atmosphere and the sea surface, ignores the change of the carbon flux in the sea water, and has certain limitation.
Therefore, the existing observation equipment does not consider the carbon flux change of the sea-gas two-phase medium, the obtained carbon flux data is quite controversial, the accurate observation of sea-gas carbon flux can not be realized, and the technical bottleneck for restricting the evaluation of sea carbon fixing capacity and the development of sea carbon fixing potential is formed.
