Using GOCI extracting information of red tide for time-series analysing in East China Sea(基于GOCI提取东海近几年赤潮信息及时序分析)

Zhejiang Daxue xuebao. Lixue ban, 2017
赤潮已经成为我国东海最普遍的海洋灾害之一.利用卫星手段监测赤潮也由来已久.采用Geostationary Ocean Color Imager(GOCI)静止卫星对东海近几年的赤潮进行了监测和分析.研究表明：1）利用Quick Atmospheric Correction(QUAC)获取GOCI的归一化离水辐射率，其中nLw(555 nm)作为赤潮事件的特征波段来监测赤潮是有效的；2）以nLw(555 nm)为峰值且通过小于1.5 mW • cm-2 • sr-1 • µm ...

Effects of seasonal variations on sediment-plume streaks from dredging operations [PDF]

, 2018
When mixtures of aggregates and water dredged from the seabed are discharged at the surface into the adjacent water from a barge, coarse sediments sink immediately and fine sediments are suspended forming a plume.

A novel quantitative analysis for diurnal dynamics of Ulva prolifera patch in the Yellow Sea from Geostationary Ocean Color Imager observation

Frontiers in Marine Science, 2023
IntroductionIn the last decade, the outbreak of large-scale green tides caused by Ulva prolifera has continuously occurred in the Yellow Sea. Satellite remote sensing techniques have been widely used to monitor the distribution area and duration of green

A new technique based on mini-UAS for estimating water and bottom radiance contributions in optically shallow waters [PDF]

, 2015
The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with respect to those derived from Lidar systems due in part

Exploiting Machine Learning to Develop Ocean Color Retrievals From the Tropospheric Emissions: Monitoring of Pollution Instrument

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Retrievals of ocean color (OC) properties from space are important for understanding the ocean ecosystem, the carbon cycle, and monitoring events such as harmful algal blooms (HABs). The recently launched U.S. National Aeronautics and Space Administration (NASA) Earth Venture Instrument, the geostationary Tropospheric Emissions: Monitoring of ...

GOCI image enhancement using an MTF compensation technique for coastal water applications

Optics Express, 2014
The Geostationary Ocean Color Imager (GOCI) is the first optical sensor in geostationary orbit for monitoring the ocean environment around the Korean Peninsula. This paper discusses on-orbit modulation transfer function (MTF) estimation with the pulse-source method and its compensation results for the GOCI.

Ocean Colour Atmospheric Correction for Optically Complex Waters under High Solar Zenith Angles: Facilitating Frequent Diurnal Monitoring and Management

Remote Sensing, 2023
Accurate atmospheric correction (AC) is one fundamental and essential step for successful ocean colour remote-sensing applications. Currently, most ACs and the associated ocean colour remote-sensing applications are restricted to solar zenith angles ...
