Abstract

The invention belongs to the technical field of polar region observation devices, and discloses a sea ice growth observation system, the sea ice growth observation system comprises a buoy and a sea ice observation subsystem, the sea ice growth observation system is characterized in that the buoy is configured to float above sea ice surface, the outer wall of the buoy is provided with concave grains for icing, the sea ice observation subsystem comprises a plurality of groups of sea ice thickness sensors which are in one-to-one correspondence along the vertical direction; and the plurality of groups of sea ice thickness sensors are arranged at the periphery of the buoy at intervals. Beneficial effects are as follows: the buoy can float on the sea throughout the year; when the temperature isreduced to an icing condition; seawater located in the concave lines can be frozen, meanwhile, the friction force between newly-generated sea ice and the buoy during sea ice freezing is increased, thefreezing strength during sea ice growth is improved, and therefore the influence of waves and ocean currents on buoy freezing can be resisted, the posture stability of the buoy during newly-generatedsea ice growth is improved, and the accuracy of observing the newly-generated sea ice is improved.

Description

technical field [0001] The invention relates to the technical field of polar observation devices, in particular to a sea ice growth observation system. Background technique [0002] Global warming is significantly amplified in the Arctic, leading to a rapid decrease in Arctic sea ice reserves, and sea ice will cause abnormal effects on global weather and climate. Scientific research in this area is currently a hot spot in the world. [0003] Changes in Arctic sea ice and sea-ice-air interactions (upper seawater below the ice, sea ice, and bottom atmosphere above the ice) are the main factors affecting the warming of the Arctic climate and the rapid decline of sea ice. The multi-parameter long-term basic environmental data of the interface, due to the usually manned observation based on the icebreaker, due to the reason of the icebreaker ship schedule, is mainly concentrated in summer, and the observation time period is short, resulting in a lack of understanding of key proce...
