Recent decreases in summer sea ice cover are spurring interest in hydrocarbon extraction and shipping in Arctic waters, increasing the risk of an oil spill in ice covered waters. With advances in unmanned vehicle operation, there is an interest in identifying techniques for remote, underwater detection of oil spills from below. High-frequency (200-565 kHz), broadband acoustic scattering data demonstrate that oil can be detected and quantified under laboratory grown sea ice and may be of use in natural settings. A simple scattering model based on the reflection coefficients from the interfaces agrees well with the data.
近期夏季海冰覆盖面积的减少引发了人们对北极水域油气开采和航运的兴趣，增加了在有冰水域发生石油泄漏的风险。随着无人运载工具操作技术的进步，人们希望找到从水下远程探测石油泄漏的技术。高频（200 - 565千赫兹）宽带声学散射数据表明，在实验室培育的海冰下能够检测到石油并对其进行量化，且该方法可能适用于自然环境。基于界面反射系数的简单散射模型与数据吻合良好。
