Abstract

The invention belongs to the field of marine observation, and in particular relates to a portable optical measurement system for a water body with a vertical section and a using method of the system. The measurement system comprises a buoyancy block, an irradiance sensor, a supporting frame body, a gravity balance adjustment hammer and a radiance sensor, wherein the buoyancy block is arranged at the top of the supporting frame body; the irradiance sensor and the radiance sensor are arranged on two sides of the supporting frame body respectively; the gravity balance adjustment hammer is installed at the lower part of the supporting frame body in a relative moving manner; the irradiance sensor and the radiance sensor move on the supporting frame body by virtue of the gravity balance adjustment hammer, and are always in the vertical direction in water. The measurement system can float away from a boat body downstream and fall slowly and freely, can continuously measure the upstream radiance and the downstream irradiance of the water body with the vertical section from a water surface to set depth, has the characteristics of simple structure and small size, can be free from the influence of the boat body and shadow so as to ensure accuracy of an optical measuring parameter, and can be used for carrying out ocean water color research, satellite calibration and confirmation and the like.

Description

technical field [0001] The invention belongs to the field of ocean observation, in particular to a portable optical measurement system for vertical section of water body and its application method. Background technique [0002] With the change of water depth, some physical quantities in the ocean water body generally have uneven distribution in the vertical section. For example, sunlight irradiates the sea surface and passes through the water body, causing the spectral irradiance and radiance of the water body optics to change vertically from the water surface to the deep layer. Profile distribution changes. And this change will also make the vertical profile distribution of chlorophyll, nutrients, etc. uneven, and the detection of the profile distribution of these parameters can provide effective data for marine ecology. However, at the position close to the survey ship, due to the influence of the ship, the measured elements such as irradiance and radiance of the water pr...
