摘要/Abstract

摘要：

海洋浮游植物光合作用固碳在全球碳循环中扮演着极为重要的角色, 获取不同光衰减对应的海水深度, 对于采集水样用于海洋初级生产力的研究具有重要意义。本研究于国际上首次开发了无缆便携式海洋透光率仪, 特殊的光学结构设计和光谱滤光技术使得光谱响应在波段400~700nm范围内超过了同类海洋传感器, 特定光衰减下对应的深度误差小于0.5m。将本设备应用于南海中尺度涡旋初级生产力的研究中, 在采样率和自动化方面验证了仪器的便携性; 通过对涡旋中初级生产力的空间分布规律进行分析, 检验了仪器数据结果的可靠性。海洋透光率仪在价格、准确性、可靠度和操作的便携性上具有不可比拟的优势, 将在未来海洋生态环境的研究中发挥重要作用。

Abstract:

Carbon sequestration by photosynthesis of marine phytoplankton plays an important role in the global carbon cycle. Obtaining the seawater depth in a condition of different light attenuation is important for studying marine primary productivity by sampling seawater. In this study, a portable marine transmittance instrument without cable was developed, the first in the world. The special optical structure design and spectral filter technology make the spectral response in the band range of 400-700 nm exceed that of similar marine sensors, and the corresponding depth error is less than 0.5 m under the specific light attenuation. The device was applied to the study of mesoscale eddy primary productivity in the South China Sea, and the portability of the instrument was verified in terms of sampling rate and automation. By analyzing the spatial distribution of primary productivity in the vortex, the reliability of the instrument data was tested. Due to its incomparable advantages in price, accuracy, reliability, and portability of operation. Finally, the marine transmittance meter will play an important role in the future research of marine ecological environment.

Key words: marine monitoring, primary productivity, photosynthetically active radiation, seawater euphotic layer, attenuation
