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.

Monitoring Red Tide in South Sea of Korea (SSK) Using the Geostationary Ocean Color Imager (GOCI)

Korean Journal of Remote Sensing, 2012
To identify Cochlodinium polykrikoides red tide from non-red tide water (satellite high chlorophyll waters) in the South Sea of Korea (SSK), we improved a spectral classification method proposed by Son et al.(2011) for the world first Geostationary Ocean Color Imager (GOCI). C.

Preliminary Study of the Tsunami Effect from the Great East Japan Earthquake using the World First Geostationary Ocean Color Imager (GOCI) [PDF]

Korean Journal of Remote Sensing, 2012
The enormous disaster (Friday nightmare) occurred at 14:46 (JST) (05:46 UTC) on 11 March 2011, officially named “the 2011 Tohoku Earthquake and Tsunami”. To monitor the variations of the marine environment after the earthquake, we used chlorophyll and Rrs(555) of GOCI and MODIS ocean color satellite data during March ~ May 2011.

Developing data-driven models for quantifying Cochlodinium polykrikoides using the Geostationary Ocean Color Imager (GOCI)

International Journal of Remote Sensing, 2017
Harmful algal blooms have caused critical problems worldwide because they pose serious threats to human health and aquatic ecosystems. In particular, red tide blooms of Cochlodinium polykrikoides have caused serious damage to aquaculture in Korean coastal waters.
