Embodiment 1

[0072] Step 1. Data Collection

[0073] (1) Domestic data: The dissolved oxygen observation data of China's fourth, fifth and sixth Arctic scientific expeditions, laboratory water sample measurement data and dissolved oxygen observation data of China's 29th Antarctic scientific expedition were collected.

[0074] Among them, the distribution map of dissolved oxygen observation stations for the fourth, fifth and sixth Arctic scientific expeditions is shown in Figure 1-Figure 3 , the distribution map of dissolved oxygen observation stations of China's 29th Antarctic Scientific Expedition is shown in Figure 4 .

[0075](2) Overseas data: collected the measured data database provided by the National Oceanographic Data Center (NODC) of the United States - the World Ocean Dataset (World Ocean Database 2013, WOD2013) in the polar regions containing dissolved oxygen observation data. The resolution CTD observation data set (High-resolution Conductivity-Temperature-Depth (CTD) data...

Abstract

The invention discloses a method for observing and correcting dissolved oxygen in a polar region. The method comprises the following steps: collecting dissolved oxygen observation data by virtue of anSBE 911Plus CTD system; and observing the data by virtue of a dissolved oxygen sensor, and carrying out processing and correction. By virtue of the replacement and backup of the dissolved oxygen sensor, the observation situation of dissolved oxygen during the polar region research is improved, and the continuity and accuracy of the observation are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of polar exploration, and in particular relates to a method for observing and correcting polar dissolved oxygen. Background technique [0002] Dissolved oxygen is one of the important basic substances of marine ecosystems. It not only has an important impact on marine biology and chemical processes, but also is an important element for exploring physical ocean processes in sea areas. As one of the most basic parameters in oceanographic research, the close relationship between dissolved oxygen and marine biological and chemical processes is the focus of research. In fact, the transport process of dissolved oxygen is accompanied by the movement of water bodies. It plays an important role in the division of water mass and the analysis of water mass characteristics. To a certain extent, it can be used to trace the changes of water mass. Its distribution characteristics are also closely related to the circulation...
