“…The technical means of deep-sea planktonic ecology research are mainly divided into plankton trawling, optical survey equipment, acoustic survey equipment, and sediment trap [11]. Due to the limitation of traditional biological trawl sampling, many researchers in recent years began to use acoustics to obtain abundance and distribution data of marine animals such as zooplankton and fish [5], so as to analyze the temporospatial changes of zooplankton's vertical movement in different sea areas [12][13].…”

Marine zooplankton have diel vertical migration behavior and play a key role in the transport of surface organic compounds to the deep ocean, which is of great significance in studying marine climate change. In this research, the manual visual interpretation method was used to preprocess the biological backscattering intensity data of acoustic Doppler current profiler (ADCP) during the eighth Arctic expedition. Results showed that the extracted vertical migration trajectory was in good agreement with the variation of backscattering intensity data. The amount of zooplankton in the Arctic Ocean is significantly lower than that in the North Pacific and the North Atlantic, and sea ice cover has a significant effect on the diel vertical migration of zooplankton. Characteristics of zooplankton distribution in the North Atlantic Ocean were analyzed based on mathematical statistical methods. The results also prove that the backscattering intensity of -90dB can distinguish scattering layer and water, and that of -78dB can distinguish general scatters and zooplankton. There are two significant concentrations of zooplankton in the Atlantic Ocean which were located at the surface and at depths of 350-450 m, respectively.
