Spectral classification of water masses under the influence of the Amazon River plumeActa Oceanologica Sinica - Tập 29 - Trang 1-8 - 2010
Gustavo Souto Fontes Molleri, Milton Kampel, Evlyn Márcia Leão de Moraes Novo
The large amount of dissolved and particulate material discharged by the Amazon River into the Equatorial Atlantic Ocean cause distinct spectral response of its waters as compared to the nearby ocean waters. This paper shows the application of K-means clustering algorithm for classifying water masses in the region under the Amazon River plume influence according to their spectral behavior.

Sedimentary elements, evolutions and controlling factors of the Miocene channel system: a case study of the deep-water Taranaki Basin in New ZealandActa Oceanologica Sinica - - 2024
Guangxu Wang, Wei Wu, Changsong Lin, Quan Li, Xiaoming Zhao, Yongsheng Zhou, Weiqing Liu, Shiqin Liang
Deep-water channel systems are important petroleum reservoirs, and many have been discovered worldwide. Understanding deep-water channel sedimentary elements and evolution is helpful for deep-sea petroleum exploration and development. Based on high-resolution 3D seismic data, the Miocene channel system in the deep-water Taranaki Basin, New Zealand, was analyzed by using seismic interpretation tech...... hiện toàn bộ
Performances of conventional fusion methods evaluated for inland water body observation using GF-1 imageActa Oceanologica Sinica - Tập 38 - Trang 172-179 - 2019
Yong Du, Xiaoyu Zhang, Zhihua Mao, Jianyu Chen
Satellite remote sensing of inland water body requires a high spatial resolution and a multiband narrow spectral resolution, which makes the fusion between panchromatic (PAN) and multi-spectral (MS) images particularly important. Taking the Daquekou section of the Qiantang River as an observation target, four conventional fusion methods widely accepted in satellite image processing, including pan ...... hiện toàn bộ
Under-ice ambient noise in the Arctic Ocean: observations at the long-term ice stationActa Oceanologica Sinica - Tập 39 - Trang 125-132 - 2020
Xiao Han, Jingwei Yin, Yanming Yang, Hongtao Wen, Longxiang Guo
Under-ice ambient noise in the Arctic Ocean is studied using the data recorded by autonomous hydrophones at the long-term ice station during the 9th Chinese National Arctic Research Expedition. Time-frequency analysis of two 7-s-long ice-induced noise samples shows that both ice collision and ice breaking noise have many outliers in the time-domain (impulsive characteristic) and abundant frequency...... hiện toàn bộ
Validation of MODIS ocean-colour products in the coastal waters of the Yellow Sea and East China SeaActa Oceanologica Sinica - Tập 39 - Trang 91-101 - 2020
Lingling Jiang, Xiangyu Guo, Lin Wang, Shubha Sathyendranath, Hayley Evers-King, Yanlong Chen, Bingnan Li
An extensive study collected in situ data along the Yellow Sea (YS) and East China Sea (ECS) to assess the radiometric properties and the concentration of the water constituents derived from Moderate Resolution Imaging Spectroradiometer (MODIS). Thirteen high quality match-ups were obtained for evaluating the MODIS estimates of Rrs(λ), chlorophyll a (Chi a) and concentrations of suspended particul...... hiện toàn bộ
