乔治浅滩海底峡谷中高密度磷虾底层水声学探测。

Abstract

High-density demersal layers of krill have been detected in the submarine canyons off Georges Bank by means of a high-frequency, dual-beam bioacoustical technique. Krill densities in these demersal layers were observed to be two to three orders of magnitude greater than the highest densities observed in water-column scattering layers. Such abundances may help explain the unusually high squid and demersal fish production estimates attributed to the Georges Bank ecosystem.

摘要

利用高频双波束生物声学技术，在乔治王湾的海底峡谷中探测到了高密度的底栖磷虾。这些底栖层中的磷虾密度比水柱散射层中观察到的最高密度高出两到三个数量级。如此高的丰度可能有助于解释归因于乔治王湾生态系统的异常高的鱿鱼和底栖鱼类产量估计。
