桑沟湾海冰厚度遥感反演研究
Sea ice thickness in the Sanggou Bay retrieved from satellite observations
摘要
Abstract
Sea ice is frequently observed in the Sanggou Bay and has significant influence on the local aquaculture community. Due to the absence of field measurements and due to rigid winter conditions that make it too hostile to conduct in-situ observations, we make use of satellite images to estimate sea ice thickness. Comparative results suggest that our estimations agree well with results from a robust model with a mean bias of 2 cm, standard devia-tion of 6 cm, and correlation coefficient of 0.76. Spatiotemporal behavior is clearly reflected in our satellite-derived thickness. Under warmer conditions, there is basically no ice in the bay. In years of moderate-to- low temperatures, the bay may be broadly covered by ice floes. The declining trend from onshore to offshore is obvious. In particular, in heavy ice years, the southern Sanggou Bay is dominated by sea ice with a mean thickness of 20 cm due to the effects of tides and winds.关键词
