烟台海岸带所在海上溢油探测及其生态影响研究取得新进展
原油溢入海水引起的乳化现象会导致其粘度、张力增加,体积增大;乳化后的原油更难清理,对海洋动、植物带来的危害增大。所以根据原油乳化特性,利用遥感手段识别泄露的原油,调查研究海上溢油对生态环境的影响是研究关注的重点。
通过室内实验发现不同沥青含量原油乳化随温度增加,张力、粘度和密度是递减的;通过实验和模式模拟发现乳化原油发生最大波阻尼的油膜厚是原油发生最大波阻尼的油膜厚度的两倍。通过户外实验发现不同沥青含量原油,在一定油膜厚度范围内,乳化原油增大后向散射,这一结论与室内实验和模拟结果当在一定油膜厚度时,波阻尼达到最大值,从而导致后向散射减小基本一致。
研究对墨西哥湾溢油(乳化)的大面积遥感识别开展了研究工作并取得一定进展。目前已发表/接收12篇文章。该研究得到中国科学院对外合作重点项目“海上溢油探测及其生态影响研究”的支持。
