用于探测、分类和定位海洋哺乳动物的被动声学技术和相关算法正在成为北约海底研究中心减轻海洋哺乳动物风险（MMRM）项目中开展科学调查的首选手段。在过去的九年里，这个强大的科学项目调查了主要关注物种居维叶喙鲸（ziphus cavirostris）的栖息地和行为，以及其他方面。SIRENA '08海试于2008年5月17日至6月18日在Alboran海进行，是支持MMRM项目的一系列此类活动中最近的一次海试。NRV联盟号的行动分为三个阶段；在第一阶段（5月19日至27日）和第二阶段（5月29日至6月6日），利用声学和视觉方法进行了样线调查，以确定鲸类的存在和不存在。在第3阶段（6月8 - 16日），对居维叶喙鲸和长鳍领航鲸（Globicephela melas）进行了重点跟踪和标记。在这三个阶段，还在海岸站进行了滑翔机操作和目视观察。在SIRENA '08期间，使用、测试和评估了几种非声学工具和技术；然而，本文将重点研究被动声学技术在巡航中的应用。
Passive acoustic technologies and associated algorithms that detect, classify and localize marine mammals are becoming the preferred means of performing scientific investigations in the marine mammal risk mitigation (MMRM) project at the NATO Undersea Research Centre. During the last nine years, this robust scientific program has investigated, among other aspects, the habitat and behavior of the primary species of concern, Cuvier's beaked whales (Ziphius cavirostris). The SIRENA '08 sea trial, conducted from 17 May to 18 June 2008 in the Alboran Sea, was the most recent sea trial in a series of such campaigns that supported the MMRM project. Operations aboard the NRV Alliance were divided into three phases; during phases 1 (19 - 27 May) and 2 (29 May - 6 June), line-transect surveys were performed using acoustic and visual methods to determine the presence and absence of cetaceans. During phase 3 (8 - 16 June), focal follow and tagging of Cuvier's beaked whales and long-finned pilot whales (Globicephela melas) were performed. Glider operations and visual observations were also performed from a shore station during all three phases. Several non-acoustic tools and techniques were used, tested and evaluated during SIRENA '08; however, this paper will focus on the passive acoustic technologies employed on the cruise.
