Abstract

The invention relates to the field of ocean-atmosphere measurement, in particular to a watertight anti-pressure storehouse body for measuring ocean-atmosphere carbon dioxide flux. The storehouse body comprises a lower storehouse body and an upper storehouse body, wherein the lower storehouse body is arranged on the lower half part of the watertight anti-pressure storehouse body; the upper storehouse body is arranged on the upper half part of the watertight anti-pressure storehouse body; and a carbon dioxide partial pressure optical fiber chemical sensor sample cell, which is connected with the upper and lower storehouse bodies respectively, of an atmosphere passage, a carbon dioxide partial pressure optical fiber chemical sensor sample cell, which is connected with the upper and lower storehouse bodies respectively, of an ocean passage, and an electrical connecting passage which is connected with the upper and lower storehouse bodies respectively are arranged between the lower storehouse body and the upper storehouse body. The watertight anti-pressure storehouse body designed by the invention has a compact and simple structure, is convenient to mount, has high sealability and pressure resistance, can be sequentially released for a long time, and is suitable for an anchoring platform and an ocean-atmosphere CO2 flux measuring instrument which adopts CO2 partial pressure opticalfiber chemical sensors.

Description

technical field [0001] The invention relates to the field of air-sea measurement, in particular to a watertight pressure-resistant chamber body applied to the measurement of air-sea carbon dioxide flux. Background technique [0002] Accurate quantification of air-sea carbon dioxide (CO 2 ) fluxes and mastering their changes on different temporal and spatial scales is one of the central tasks in the study of global carbon cycle and climate change. Based on ship-borne observations, the surface seawater and sea surface atmospheric CO 2 On-site measurement of partial pressure is the most widely used and most recognized method for estimating sea-air CO 2 flux method. However, the instruments used in shipborne aerial surveys are expensive, and it is difficult to achieve fixed-point observations of long-term time series. In the past decade, with the CO 2 The partial pressure optical fiber chemical sensor technology has made great progress, which makes it possible to develop a ...
