Until now, continental shelf environments have been monitored with highly localized line-transect methods from slow-moving research vessels. These methods significantly undersample fish populations in time and space, leaving an incomplete and ambiguous record of abundance and behavior. We show that fish populations in continental shelf environments can be instantaneously imaged over thousands of square kilometers and continuously monitored by a remote sensing technique in which the ocean acts as an acoustic waveguide. The technique has revealed the instantaneous horizontal structural characteristics and volatile short-term behavior of very large fish shoals, containing tens of millions of fish and stretching for many kilometers.
到目前为止，大陆架环境一直是通过慢速行驶的研究船只采用高度局部化的断面线方法进行监测的。这些方法在时间和空间上对鱼类种群的采样严重不足，留下了关于丰度和行为的不完整且模糊的记录。我们表明，大陆架环境中的鱼类种群可以通过一种遥感技术瞬间成像数千平方公里，并持续进行监测，在这种技术中海洋充当声波导。该技术揭示了包含数千万条鱼且绵延数公里的非常大的鱼群的瞬时水平结构特征和多变的短期行为。
