Problems solved by technology
The main difficulties faced in the measurement are: during the measurement, the probe measurement plane and the subsurface of the sea ice need to maintain a horizontal micro-contact. If the distance is too close, the surface of the probe will be damaged. If the distance is too far, the authenticity of the measurement cannot be guaranteed. Therefore, , what kind of auxiliary measuring device and measuring method should be used for the measurement to ensure that the measuring plane of the probe and the subsurface of the sea ice are in horizontal micro-contact?
[0004] At present, there is no dedicated commercial instrument for measuring the sea ice transmission spectrum. Researchers mostly use various self-developed sea ice transmission spectrum measurement devices when measuring the sea ice transmission spectrum, and most of them are based on the ground. It is refitted from a physical spectrometer, and there is no perfect solution for the above-mentioned difficulties in measuring the sea ice transmission spectrum.

Embodiment Construction
[0019] Such as figure 1 As shown, the present invention is a radiation measurement device for the lower layer of the ice body, which is composed of a data acquisition device 1 , a probe device 4 and an auxiliary measurement device 5 . Among them, 3 are ice bodies, and 2 are ice caves dug on the ice body.
[0020] Such as figure 2 As shown, it is a specific schematic diagram of measuring the floating body through radiation, in which 6 and 7 are cylinders, and the length of the cylinder is 6cm. There are four cylinders, which are respectively located at 0 degrees, 90 degrees, 180 degrees and 270 degrees of the floating body Location. The role of the cylinder can make the floating body not completely close to the bottom of the sea ice, so as to protect the probe and reduce the influence of the reflection of the upper baffle on the light field. 8 is a radiance probe or an irradiance probe. The probe is watertight at a water depth of 20m. By replacing the two probes, radiation...

A sea ice transmission spectrum measurement device, including a data acquisition device, a transmission spectrum measurement probe device, and an auxiliary measurement device, the data acquisition device is connected to the probe device for collecting data measured by the probe device, The auxiliary measurement device is a floating body, and the probe device is installed in the floating body. There is a layer of black baffles with low density on the upper and lower sides of the floating body. The upper baffle is provided with four cylinders, so that the floating body is not completely close to the sea. the bottom of the ice to protect the probe.
Description
technical field [0001] The invention relates to the field of marine monitoring, in particular to a sea ice transmission spectrum measuring device and a measuring method thereof. Background technique [0002] Sea ice transmission spectrum is one of the key parameters in sea ice related research. Accurate and simple measurement of sea ice transmission spectrum is an unavoidable basic technical problem in any sea ice optical radiation measurement. [0003] The common method for sea ice transmission spectrum measurement is: first select the ice surface to be measured, and then dig an ice hole at an appropriate distance from the selected ice surface along the sunlight, and send the measuring probe under the measured sea ice through the ice hole. Measuring sea ice transmission spectra. The main difficulties faced in the measurement are: during the measurement, the probe measurement plane and the subsurface of the sea ice need to maintain a horizontal micro-contact. If the distanc...
