Abstract：
The authors utilized remote sensing data from the visible and near-infrared bands of the Gaofen-4 satellite during clear days in the winter of 2021 to 2022 in the Liaodong Bay to invert the thickness of sea ice. 12 polygon vectors of the navigable waters in the Liaodong Bay were obtained from China sailing directions: Bohai Sea and Yellow Sea. The Risk Index Outcome (RIO) dataset for non-ice-strengthened vessels in the navigable waters of the Liaodong Bay were obtained using the Polar Operations Limitations Assessment Risk Index System (POLARIS) methodology. The dataset includes: (1) 12 polygon vector data of the navigable waters in the Liaodong Bay. (2) RIO values for 12 navigable waters in the Liaodong Bay on 44 clear days. The first line in the table include the dates of clear days, and 12 navigable waters. The dataset is archived in .shp and .xlsx formats, and consists of 97 data files with data size of 78.7 KB (Compressed into one file with 36.2 KB). The research findings based on the dataset was published at Journal of Marine Science and Engineering, Vol. 12, No. 5, 2024.
