Portable field ice core observation device

Abstract

The invention relates to a portable field ice core observation device. The portable field ice core observation device is structurally characterized in that a light box and an ice core groove form a sealed body; the upper end face of the light box is provided with the ice core groove which is a semi-circular concave object, the two sides of the ice core groove are provided with rulers, one end of the ice core groove is a sealed end, and the end face of the sealed end of the ice core groove is flush with zero graduation lines of the rulers; light bases on the inner side wall of the light box are provided with light tubes, the two ends of each light tube are connected with a power supply through power lines, the two ends of a switch are connected with the light bases through power lines, a bottom plate of the light box is provided with a telescopic bushing support, and bushings are fixed through knob locks. The portable field ice core observation device is reasonable in design, compact in structure, light and convenient to use, facilitates field transportation and quick assembly, can meet the requirements of field on-site ice core description work, can effectively and accurately describe and record physical parameters and physical information of an ice core, and provides the most primitive, reliable and basic scientific data for later ice core recoding and research.

Description

technical field [0001] The invention relates to an observation device, in particular to a portable device used in the field to observe and record physical parameters and information of drilled ice cores. [0002] Background technique [0003] Polar and mountain glaciers are formed by the accumulation and compaction of snow layers over millions of years into ice. During this process, glaciers record information about climate and environmental changes in different historical periods. Ice cores are used to drill a glacier to obtain a cylindrical continuous ice layer. Scientists can extract physical, chemical and biological information through ice cores. This information can truly reproduce the environmental and climatic characteristics of the glacial period. Some physical information contained in the ice core can be observed with the naked eye, such as the annual layer of the ice core, the type of granular snow, the deposition layer of atmospheric dust, the deposition layer ...

AI Technical Summary

Problems solved by technology

At present, due to the extremely harsh environmental conditions in the field of ice core drilling and the difficulty of material transportation, the description of ice cores is usually carried out on a temporary flat snow platform on the ground. Due to the lack of corresponding observation devices and good lighting facilities , the physical information contained in some ice cores cannot be clearly and accurately observed with the naked eye, and it is easy to miss and misjudge some important physical information; in addition, due to the low height of the snow platform, the staff can only observe in a sitting or squatting position, and cannot Move your body position flexibly to carefully observe the physical information of different parts of the ice core
