Characterizing the Sound-Scattering Layer and Its Environmental Drivers in the North Equatorial Current of the Central and Western Pacific Ocean by Tianji Gao, Jianfeng Tong, Minghua Xue, Zhenhong Zhu, Yue Qiu, Richard Kindong, Qiuyun Ma, Jun Li

“…In this study, we statistically analyzed the spatiotemporal factors of 10–200 m SSL in the NEC of the Central and Western Pacific Ocean using acoustic survey data collected by the “Songhang” research vessel (RV) in 2022, and the influence of environmental factors on the scattering layer distribution was analyzed using the Generalized Additive Model (GAM). …”

Broadband Characteristics of Zooplankton Sound Scattering Layer in the Kuroshio–Oyashio Confluence Region of the Northwest Pacific Ocean in Summer of 2019 by Minghua Xue, Jianfeng Tong, Siquan Tian, Xuefang Wang

“…To understand its spatial–temporal distribution, acoustic data of the Kuroshio–Oyashio confluence region at the Northwest Pacific Ocean, obtained by a Simrad EK80 broadband scientific echosounder in 2019, were used on board the research vessel (RV) Songhang. After noise removal, the volume backscattering strength (<i>S_V</i>) was measured to plot the broadband scattering spectrogram of each water layer and to exhibit zooplankton distribution. …”

Assessing the influence of abiotic factors on small pelagic fish distribution across diverse water layers in the Northwest Pacific Ocean through acoustic methods by Zhenhong Zhu, Jianfeng Tong, Minghua Xue, Ousmane Sarr, Tianji Gao

“…This study used acoustic measurement data collected by the scientific research vessel “Songhang” equipped with a Simrad EK 80 scientific echosounder from June to July 2022, to estimate the small pelagic fish resource density in different water layers from 0 to 200 m. …”
