Spectral classification of water masses under the influence of the Amazon River plume
Acta 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.

Clay minerals in Arctic Kongsfjorden surface sediments and their implications on provenance and paleoenvironmental change
Acta Oceanologica Sinica - - 2018
Fang Shi, Xuefa Shi, Xinming Su, Xisheng Fang, Yonghua Wu, Zhizhong Cheng, Zhengquan Yao
Sedimentary elements, evolutions and controlling factors of the Miocene channel system: a case study of the deep-water Taranaki Basin in New Zealand
Acta 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 image
Acta 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 station
Acta 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 Sea
Acta 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
Sea surface temperature retrieval based on simulated microwave polarimetric measurements of a one-dimensional synthetic aperture microwave radiometer
Acta Oceanologica Sinica - Tập 40 - Trang 122-133 - 2021
Mengyan Feng, Weihua Ai, Wen Lu, Chengju Shan, Shuo Ma, Guanyu Chen
Compared with traditional real aperture microwave radiometers, one-dimensional synthetic aperture microwave radiometers have higher spatial resolution. In this paper, we proposed to retrieve sea surface temperature using a one-dimensional synthetic aperture microwave radiometer that operates at frequencies of 6.9 GHz, 10.65 GHz, 18.7 GHz and 23.8 GHz at multiple incidence angles. We used the ERA5 ...... hiện toàn bộ
Phylogenetic diversity of dimethylsulfoniopropionatedependent demethylase gene dmdA in distantly related bacteria isolated from Arctic and Antarctic marine environments
Acta Oceanologica Sinica - Tập 38 - Trang 64-71 - 2019
Yinxin Zeng
Dimethylsulfoniopropionate (DMSP) is mainly produced by marine phytoplankton as an osmolyte, antioxidant, predator deterrent, or cryoprotectant. DMSP is also an important carbon and sulfur source for marine bacteria. Bacteria may metabolize DMSP via the demethylation pathway involving the DMSP demethylase gene (dmdA) or the cleavage pathway involving several different DMSP lyase genes. Most DMSP r...... hiện toàn bộ
Impacts of oceanographic factors on interannual variability of the winter-spring cohort of neon flying squid abundance in the Northwest Pacific Ocean
Acta Oceanologica Sinica - Tập 36 - Trang 48-59 - 2017
Wei Yu, Xinjun Chen, Changsheng Chen, Yu Zhang
The neon flying squid Ommastrephes bartramii is an economically important species in the Northwest Pacific Ocean. The life cycle of O. bartramii is highly susceptible to climatic and oceanic factors. In this study, we have examined the impacts of climate variability and local biophysical environments on the interannual variability of the abundance of the western winter-spring cohort of O. bartrami...... hiện toàn bộ
