Monitoring the Characteristics of the Bohai Sea Ice Using High-Resolution Geostationary Ocean Color Imager (GOCI) Data

Abstract: Satellite remote sensing data, such as moderate resolution imaging spectroradiometers (MODIS) and advanced very high-resolution radiometers (AVHRR), are being widely used to monitor sea ice conditions and their variability in the Bohai Sea, the southernmost frozen sea in the Northern Hemisphere. Monitoring the characteristics of the Bohai Sea ice can provide crucial information for ice disaster prevention for marine transportation, oil field operation, and regional climate change studies. Although these satell… Show more

“…Comparing the SIT between 2012 and 2013, we can see that the SIT in February 2013 is larger than that in February 2012, as shown in Figure 6a-l,r-u. This finding is consistent with Yan's results [30]. Focusing on January and February 2013, SIT tends to decrease over time, and the findings confirm the statistical results: the sea ice in LDB began to melt gradually at the end of February and early March.…”

“…Therefore, the information of all bands is needed for ice thickness inversion. In Yan's paper [30], the information of all the bands is also used to carry out ice thickness inversion. Even with combinations of 3 bands, the retrieval results have slightly lower skill scores for JZ20-2 than for JZ9-3 because the in situ SIT falls within a range, and the variation range for JZ20-2 is larger than that for JZ9-3.…”

“…For example, the first geostationary ocean color imager (GOCI, data available since 2011), operated by the Korea Institute of Ocean Science & Technology, has demonstrated its unique contributions in capturing the diurnal changes of red tides, turbidity plumes, water quality and ocean surface current, etc. [5][6][7][8][9][10][11][12], given its temporal resolution of eight hourly observations per day. Although they have coarse spectral and spatial resolutions, geostationary meteorological satellites (such as the Himawari-8 from the Japan Meteorological Agency and the Geostationary Operational Environmental Satellite (GOES) from NOAA) boast high observational frequencies (tens of minutes), allowing them to detect, for example, the short-term dynamics of floating algae [13][14][15].…”

“…Although the use of optical remote sensors is constrained by the weather conditions, they have the merits of finer spatial resolution, low cost, and a short revisit period (one day or less). Thus, optical remote sensors such as the Advanced Very High-Resolution Radiometer (AVHRR) [14], Moderate Resolution Imaging Spectroradiometer (MODIS) [15][16][17][18], Geostationary Ocean Color Imager (GOCI) [19][20][21], and FengYun-3 Medium Resolution Spectral Imager (MERSI) [22] have been effectively employed to extract sea ice distribution information via a variety of methods. For example, rapid and effective sea ice extraction has been achieved with a ratio-threshold segmentation method based on the red and infrared bands of MODIS images [2,23].…”
