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 ...

Diurnal Variability of Submesoscale Chlorophyll‐a Fronts Revealed by Hourly Geostationary Satellite Observations

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The detection of submesoscale fronts is critical for understanding physical‐biological interactions and ecosystem variability. This study characterizes the diurnal variability of chlorophyll‐a (Chl‐a) fronts using hourly data from the geostationary satellite GK‐2B/GOCI‐II in the East/Japan Sea.

Evaluation of GOCI Remote Sensing Reflectance Spectral Quality Based on a Quality Assurance Score System in the Bohai Sea

Remote Sensing, 2022
In the application of ocean color remote sensing, remote sensing reflectance spectral (Rrs(λ)) is the most important and basic parameter for the development of bio-optical algorithms.

Daily Sun‐induced chlorophyll fluorescence vs. irradiance curves reflect the photoadaptation of phytoplankton in surface waters

Limnology and Oceanography, Volume 70, Issue 4, Page 1001-1015, April 2025.
Abstract Phytoplankton chlorophyll Sun‐induced fluorescence is observable in the upwelling light field of the ocean. This allows its observation by radiometers in situ or on satellite sensors. Since it is influenced by both biomass and physiology it can potentially provide information about both.

Comparison of NDVIs from GOCI and MODIS Data towards Improved Assessment of Crop Temporal Dynamics in the Case of Paddy Rice

Remote Sensing, 2015
The monitoring of crop development can benefit from the increased frequency of observation provided by modern geostationary satellites. This paper describes a four-year testing period from 2010 to 2014, during which satellite images from the world's ...

Tide-Induced Variability and Mechanisms of Surface Suspended Sediment in the Zhoushan Archipelago along the Southeastern Coast of China Based on GOCI Data

Remote Sensing, 2021
The variations and dynamics of suspended sediment in the coastal waters around the Zhoushan Archipelago are complex due to strong tidal dynamics. This study aims to delineate the tide-induced variability of surface suspended sediment and reveal its ...

Short‐Term Sea Fog Area Forecast: A New Data Set and Deep Learning Approach

Journal of Geophysical Research: Machine Learning and Computation, Volume 1, Issue 3, September 2024.
Abstract Prompt and precise forecast of sea fog regions ensures maritime navigational safety. This paper establishes a prompt and precise forecast of sea fog regions that ensure maritime navigational safety. This paper establishes a multivariable sea fog forecast (MV‐SFF) data set and proposes a deep learning‐based forecast method named rich‐element ...

Identifying algal bloom types and analyzing their diurnal variations using GOCI-Ⅱ data

International Journal of Applied Earth Observations and Geoinformation
Frequent algal blooms pose a serious threat to the marine ecosystem of the East China Sea. The Geostationary Ocean Color Imager-Ⅱ (GOCI-Ⅱ), a second-generation geostationary satellite sensor, is crucial for monitoring marine environmental dynamics.

Recent warming of the Kuroshio Current has promoted offshore sediment transport in the Yellow Sea

Limnology and Oceanography Letters, Volume 9, Issue 4, Page 452-460, August 2024.
Abstract As cross‐shelf gradients of most properties are typically much steeper than those in the alongshore direction, transport across isobaths tends to be inhibited, particularly at oceanic fronts where cross‐shelf gradients are markedly pronounced.

Spatial, seasonal and climatic drivers of suspended sediment atop Great Bahama Bank

Sedimentology, Volume 71, Issue 3, Page 769-792, April 2024.
ABSTRACT Suspension is the key mechanism by which fine‐grained sediment (≤125 μm) is winnowed and transported across shallow‐water carbonate platforms into adjacent deep waters. Unlike sliding and saltation, which deliver sedimentary structures via bedload, the sedimentological signature of suspended sediment is more cryptic.
