Polar region sea ice environmental data monitoring buoy and polar region sea ice environmental data monitoring method

Abstract

The invention discloses a polar region sea ice environmental data monitoring buoy and a polar region sea ice environmental data monitoring method. Atmospheric parameters of positions at different heights within 4 meters above an ice surface can be measured and include the air speeds, the air directions, the air temperatures, the air pressure and humidity of the positions at different heights; thecontent of seawater dissolved oxygen and chlorophyll of positions at different depths under the ice surface can be acquired as well; the on-ice snowfall and the ice and water interface distance are measured through overwater sonar and underwater sonar, and the change of the total thickness of an ice layer can be obtained; data are transmitted through an iridium satellite module, automatic remote real-time monitoring is achieved, and analysis reference is provided for the thermodynamic change process in the sea ice growth process; compared with other buoy devices, the buoy has the beneficial effects of being novel in structure and diverse in measured data; and the buoy and method can be used for automatic unmanned monitoring of south and north pole polar region sea ice.

Description

technical field [0001] The invention relates to the field of automatic monitoring, in particular to a polar sea ice environment data monitoring buoy and a polar sea ice environment data monitoring method. Background technique [0002] The global climate is a unity of various factors interacting with each other, and the climate in the North and South Poles is one of the most climate-sensitive regions on the earth. Sea ice can cover up to about 7% of the earth's surface area every year, and the largest part is distributed in the north and south poles of the earth. Obviously, sea ice occupies a large proportion in the research of the north and south poles. The change of polar sea ice is the wind vane of polar climate change. The observation and research of sea ice buoys and the application of their results play an important role in polar research. Sea ice buoys are used to observe the drift position of sea ice, the air pressure and temperature at the position of the buoy, and t...

Problems solved by technology

[0004] At present, most of the buoys placed on the polar sea ice at home and abroad are equipped with a 1-6 meter high fixed bracket on the upper part of the main body, and the same type of monitoring sensors are installed on the bracket at different heights. Chain or anchor chain, the same type of monitoring sensors are installed at different depths on the iron chain. The main disadvantage of this type of buoy is: the higher the upper fixing bracket, the larger the diameter and height of the buoy are required, otherwise the buoy will fall down.

Installing the same type of sensors at different depths on the lower iron chain will increase the number of sensors and increase the cost
