Three-dimensional acoustic propagation of noise from impact pile driving in a complex costal environment and its effects on large yellow croaker (Pseudosciaena crocea)

Autor: Jiarui Xie, Ruichao Xue, Fuqiang Niu, Benqing Chen, Yanming Yang

Publikováno v: Frontiers in Marine Science, Vol 11 (2024)

The effects of high-intensity impulsive noise generated by pile driving on fish are a major concern in environmental impact assessments. Numerical acoustic models are essential for predicting underwater-acoustic-related problems in complex coastal en

Effect of the One-to-Many Relationship between the Depth and Spectral Profile on Shallow Water Depth Inversion Based on Sentinel-2 Data

Autor: Erhui Huang, Benqing Chen, Kai Luo, Shuhan Chen

Publikováno v: Remote Sensing, Vol 16, Iss 10, p 1759 (2024)

In shallow water, Sentinel-2 multispectral imagery has only four visible bands and limited quantization levels, which easily leads to the occurrence of the same spectral profile but different depth (SSPBDD) phenomenon, resulting in a one-to-many rela

Assessing differences in acoustic characteristics from impact and vibratory pile installation and their potential effects on the large yellow croaker (Pseudosciaena crocea)

Autor: Fuqiang Niu, Jiarui Xie, Xuexin Zhang, Ruichao Xue, Benqing Chen, Zhenwen Liu, Yanming Yang

Publikováno v: Frontiers in Marine Science, Vol 10 (2023)

Underwater noise from anthropogenic activities can have negative behavioral and physical effects on marine life, including physical changes, injuries, and death. Impact pile driving and vibratory pile driving are generally used for the construction o

Evaluation and Improvement of No-Ground-Truth Dual Band Algorithm for Shallow Water Depth Retrieval: A Case Study of a Coastal Island

Autor: Qingjie Yang, Jianyu Chen, Benqing Chen, Bangyi Tao

Publikováno v: Remote Sensing, Vol 14, Iss 24, p 6231 (2022)

Conventional bathymetric inversion approaches require bathymetric data as ground truth to obtain shallow water depth from high spatial resolution remote sensing imagery. Thus, bathymetric mapping methods that do not require inputs from in situ measur

A dual band algorithm for shallow water depth retrieval from high spatial resolution imagery with no ground truth

Autor: Huang Erhui, Yang Yanming, Xu Dewei, Benqing Chen

Publikováno v: ISPRS Journal of Photogrammetry and Remote Sensing. 151:1-13

For shallow water depth retrieval from high spatial resolution satellite images, although numerous empirical models have been developed, it remains impossible to estimate shallow water depths without collection of required ground truth depth. To addr

Baseline assessment of ocean ambient noise in the western Clarion Clipperton Zone, Pacific Ocean

Autor: Ruichao Xue, Fuqiang Niu, Benqing Chen, Yanming Yang, Hailin Ruan, Kai Luo

Publikováno v: Marine pollution bulletin. 173

Ocean noise in the western Clarion Clipperton Zone, Pacific Ocean was recorded for 5 min every hour during 2017 and 2018, at a depth of 300 m. The monthly and hourly mean spectrum levels in the 20-1000 Hz band were calculated, along with their skewne

High-resolution monitoring of beach topography and its change using unmanned aerial vehicle imagery

Autor: Kai Luo, Hailin Ruan, Benqing Chen, Fuhuang Zhong, Zaiming Zhou, Hongtao Wen, Yanming Yang

Publikováno v: Ocean & Coastal Management. 160:103-116

Beaches suffer from considerable degradation due to the dual influences from natural and human-induced factors. Higher resolution topographic data are frequently needed for assessment of the rapid changes and for building the models that can predict

Estimating Spartina alterniflora fractional vegetation cover and aboveground biomass in a coastal wetland using SPOT6 satellite and UAV data

Autor: Zaiming Zhou, Yanming Yang, Benqing Chen

Publikováno v: Aquatic Botany. 144:38-45

Spartina alterniflora (S. alterniflora) is one of the most serious invasive species in some coastal wetlands of China, and its fractional vegetation cover (FVC) and aboveground biomass (AGB) are important parameters that affect the ecology of these w
