Mapping the Changjiang Diluted Water in the East China Sea during summer over a 10-year period using GOCI satellite sensor data

Frontiers in Marine Science, 2022
The Changjiang River loads freshwater into the East China Sea (ECS) and the Yellow Sea (YS). A low-salinity plume known as Changjiang Diluted Water (CDW) is formed by mixing with saline ambient waters; it disperses toward Jeju Island and the East/Japan ...

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.

A Net CO2 Sink in the Korea Strait and East/Japan Sea Revealed by Direct Eddy Covariance Measurements

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract The Korea Strait (KS) and East/Japan Sea (EJS), Kuroshio‐influenced regions of the northwestern Pacific, are important yet still poorly constrained components of the regional carbon budget. Air‐sea carbon dioxide (CO2) fluxes in KS and EJS were quantified using direct eddy covariance measurements collected during seasonal cruises between 2023 ...

Improvement of GOCI-II Water Vapor Absorption Correction through Fusion with GK-2A/AMI Data

Remote Sensing, 2023
In remote sensing of the ocean color, in particular, in coarse-resolution global model simulations, atmospheric trace gases including water vapor are generally treated as auxiliary data, which create uncertainties in atmospheric correction.

Latitude Dictates Global Marine Diatom Dynamics: Insights From 25 years of Satellite Data

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Marine diatoms are key players in global biogeochemical cycles, yet their spatiotemporal dynamics and the underlying drivers remain poorly understood. Here, we developed a novel remote sensing model and utilized 25 years of global satellite data to investigate marine diatom biomass.

Concurrent Variations in Air–Sea Heat Fluxes and Sea Ice Extensions Under Cold‐Air Outbreaks: The First Joint Buoy–Cruise Observational Results in the Bohai Sea

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The air–sea interface near seasonal ice edges notably regulates the regional climate but remains poorly understood. We present the first coordinated buoy–cruise measurements in the Bohai Sea—the world's lowest‐latitude seasonal ice zone—during the winter of 2024–2025.

The Applicability of the Geostationary Ocean Color Imager to the Mapping of Sea Surface Salinity in the East China Sea

Remote Sensing, 2021
During the summer season, low-salinity water (LSW) inputs from the Changjiang River are observed as filamentous or lens-like features in the East China Sea.

Variations of transparency derived from GOCI in the Bohai Sea and the Yellow Sea

Optics Express, 2018
Secchi disk depth (Zsd), represents water transparency which is an intuitive indicator of water quality and can be used to derive inherent optical properties, chlorophyll-a concentrations, and primary productivity. In this study, the Zsd was derived from the Geostationary Ocean Color Imager (GOCI) data over the Bohai Sea (BHS) and the Yellow Sea (YS ...

A review of the FATIMA Yellow Sea field campaign research

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 777, April 2026 Part B.
The FATIMA marine fog project took place over the Sable Island region of eastern Canada (summer 2022) and the Yellow Sea of the Republic of Korea (ROK, summer 2023). Its goals are to improve marine fog monitoring and forecasting. Instrumented multiple research vessels, aircraft, tethered balloon and autonomous systems, ocean observation sites, and ...
