Abstract:
Features in this feature class represent animal sightings recorded during aerial monitoring surveys for marine mammals and sea turtles performed in January, February, and August 2014 in the Hawaii Range Complex (HRC). Aerial surveys were conducted subsequent to two naval training events in HRC. The surveys involved circumnavigation of the island of Kauai in January–February using a ASTAR 350 B2-7 helicopter, and the islands of Oahu, Maui, Molokai, Lanai and Kahoolawe in August using a Bell 206L3 helicopter . The associated training events (Koa Kai and Rim of the Pacific or “RIMPAC”) involved the use of mid-frequency active sonar and, in the case of RIMPAC, explosives. The Koa Kai event took place primarily on the Pacific Missile Range Facility Barking Sands Tactical Underwater Range and Barking Sands Underwater Range Extension between Kauai and Niihau, Hawaii, during 24–31 January 2014. Following the Koa Kai event, shoreline surveys were conducted on 31 January and 5 February. RIMPAC took place during an extended period from 8 July through 2 August 2014 and involved a broader expanse of ocean off the main Hawaiian Islands. The aerial shoreline surveys performed subsequent to RIMPAC circumnavigated the five islands of Oahu, Maui, Molokai, Lanai and Kahoolawe over 4 days on 1 and 4–6 August. All surveys involved looking for stranded or near-stranded marine mammals, and observers documented the positions and behavior of all marine mammals and sea turtles seen within 3 km of shore. The survey platform was a small fixed-wing Aero Commander 500. Work was performed under HDR task order KB26 (IDIQ contract award N62470-10-D-3011, NAVFAC LANT).

摘要：本特征类中的特征代表在2014年1月、2月和8月对海洋哺乳动物和海龟进行空中监测调查期间记录的动物目击事件。这些调查在夏威夷范围复合体（HRC）的两个海军训练活动之后进行。空中调查包括环绕考艾岛（Kauai）的飞行，使用 ASTAR 350 B2-7 直升机于1月至2月进行，以及使用贝尔206L3直升机于8月环绕奥ahu、茂宜、摩洛凯、拉奈和卡胡拉维岛。相关的训练活动（科阿凯和环太平洋军演或“RIMPAC”）涉及中频主动声纳的使用，以及RIMPAC活动中爆炸物的使用。科阿凯活动主要在太平洋导弹靶场巴可沙战术水下靶场和巴可沙水下靶场延伸区（位于考艾岛和尼豪岛之间）于2014年1月24日至31日进行。科阿凯活动之后，于1月31日和2月5日进行了海岸线调查。环太平洋军演在2014年7月8日至8月2日的延长期间进行，涉及主夏威夷群岛附近的更广阔海域。环太平洋军演之后的空中海岸线调查在8月1日和4日至6日的4天内环绕奥ahu、茂宜、摩洛凯、拉奈和卡胡拉维岛的五座岛屿进行。所有调查均旨在寻找搁浅或几乎搁浅的海洋哺乳动物，观察者记录了所有在岸边3公里范围内看到的海洋哺乳动物和海龟的位置和行为。调查平台为一架小型固定翼航空指挥官500飞机。工作是在HDR任务订单KB26（IDIQ合同授予N62470-10-D-3011，NAVFAC LANT）下进行的。
