Characterization of ocean color retrievals and ocean diurnal variations using the Geostationary Ocean Color Imager (GOCI)

International Journal of Applied Earth Observations and Geoinformation, 2023
Using measurements from the Geostationary Ocean Color Imager (GOCI) on the Communication, Ocean, and Meteorological Satellite (COMS), we characterize and quantify some advantages and applications of the satellite geostationary measurements, compared with

Seasonal bias in global ocean color observations. [PDF]

Appl Opt, 2021
In this study, we identify a seasonal bias in the ocean color satellite-derived remote sensing reflectances ( R r s ( λ ) ; s r − 1 ) at the ocean color validation site, Marine Optical BuoY ...

High-resolution ocean color imagery from the SeaHawk-HawkEye CubeSat mission [PDF]

Scientific Data
Here we describe the data obtained by a successful proof-of-concept initiative to launch the first ocean color imager on board a CubeSat satellite and collect research-grade imagery at severalfold higher spatial resolution than any other ocean color ...

Gradient Boosting for the Spectral Super-Resolution of Ocean Color Sensor Data [PDF]

Sensors
We present a gradient boosting framework for reconstructing hyperspectral signatures in the visible spectrum (400–700 nm) of satellite-based ocean scenes from limited multispectral inputs.

Comparative analysis of GOCI ocean color products. [PDF]

Sensors (Basel), 2015
The Geostationary Ocean Color Imager (GOCI) is the first geostationary ocean color sensor in orbit that provides bio-optical properties from coastal and open waters around the Korean Peninsula at unprecedented temporal resolution. In this study, we compare the normalized water-leaving radiance (nLw) products generated by the Naval Research Laboratory ...

Using Machine Learning for Timely Estimates of Ocean Color Information From Hyperspectral Satellite Measurements in the Presence of Clouds, Aerosols, and Sunglint

Frontiers in Remote Sensing, 2022
Retrievals of ocean color from space are important for better understanding of the ocean ecosystem but can be limited under conditions such as clouds, aerosols, and sunglint.

The Colors of the Ocean Plastics [PDF]

Environmental Science & Technology, 2020
Characterization of the color of the plastic is often included in studies on plastic pollution. However, the comparability and relevance of this information is limited by methodology or observer subjectivity. Based on the analysis of thousands of floating plastic fragments from a global collection, here we propose a systematic semiautomatic method to ...
