Embodiment 1

[0072] Step 1. Data collection

[0073] (1) Domestic data: The dissolved oxygen sensor observation data of China's fourth, fifth and sixth Arctic scientific expeditions and laboratory water sample measurement data and the dissolved oxygen sensor 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 , see the distribution map of dissolved oxygen observation stations during China's 29th Antarctic Scientific Expedition Figure 4 .

[0075] (2) Foreign data: Collected the measured data database provided by the US National Oceanographic Data Center (NODC) - the World Ocean Database (World Ocean Database 2013, WOD2013) in polar regions containing dissolved oxygen sensor observation data. High-resolution CTD observation data set (High-resolution Conductivity-Temperature-Depth (CTD) ...

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 polar dissolved oxygen observation and correction. Background technique [0002] Dissolved oxygen is one of the important basic substances of the marine ecosystem. It not only has an important impact on marine biology and chemical processes, but also is an important element for exploring the physical oceanic processes in the sea area. As one of the most basic parameters of oceanographic research, the close relationship between dissolved oxygen and marine organisms and chemical processes is the focus of research. In fact, the transport process of dissolved oxygen is accompanied by the movement of water micromass, so dissolved oxygen is in the Water mass division and analysis of water mass characteristics play an important role. To a certain extent, it can be used to track the changes of water mass. Its distribution characteristics are also closel...
