北极露脊鲸（Balaena mysticetus）在秋季迁徙时暴露在阿拉斯加博福特海的石油勘探活动中。虽然以前对工业噪音对鲸鱼行为和分布的影响的研究已经注意到了显着的反应，但这项研究往往是从参数统计框架出发的。为了解释空间自相关和相互关联的数据的存在，我们提出了一套空间分析技术来评估北极露脊鲸相对于石油勘探活动的分布。使用随机rescent技术和曼特尔测试，我们分析了1993年在活跃的钻井平台周围的露脊鲸的分布。重新定位测试的结果表明，鲸鱼分布在离钻井平台更远的地方，而不是在随机情况下。Mantel试验的结果表明，在1993年，露脊鲸分布的空间格局与距钻机的距离高度相关，表明钻机的存在导致了可用栖息地的显著暂时丧失。这些技术为海洋空间分析提供了新的视角
Bowhead whales (Balaena mysticetus) on their fall migration are exposed to oil exploration activities in the Alaskan Beaufort Sea. While previous research into the effect of industrial noise on whale behavior and distribution has noted significant responses, this research has often proceeded from a parametric statistical framework. To account for the presence of spatially autocorrelated and intercorrelated data, we propose a suite of spatial analysis techniques to assess the distribution of bowhead whales relative to oil exploration activities. Using random resampling techniques and Mantel tests, we analyzed the distribution of bowhead whales around active drilling rigs in 1993. Results from the resampling tests indicated that whales were distributed farther from the drilling rig than they would be under a random scenario. Results from the Mantel tests indicated that in 1993, the spatial pattern of bowhead whale distribution was highly correlated with distance from the drilling rig, indicating that the presence of the drilling rig resulted in a signifi - cant temporary loss in available habitat. These techniques offer a new perspective on spatial analysis in the marine
