Original provider: HDR Environmental, Operations and Construction, Inc. Dataset credits: The U.S. Navy Marine Species Monitoring Program 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).原始提供方：HDR环境、运营与建筑公司（HDR Environmental, Operations and Construction, Inc.） 数据集致谢：美国海军海洋物种监测计划（The U.S. Navy Marine Species Monitoring Program） 摘要：本要素类中的要素代表2014年1月、2月及8月，在夏威夷靶场综合体（Hawaii Range Complex, HRC）开展的海洋哺乳动物与海龟航空监测调查中记录的动物目击事件。本次航空调查于HRC内两次海军训练活动后开展：1月至2月，调查团队使用ASTAR 350 B2-7直升机环绕考艾岛（Kauai）开展作业；8月则使用Bell 206L3直升机，对瓦胡岛（Oahu）、毛伊岛（Maui）、莫洛凯岛（Molokai）、拉奈岛（Lanai）及卡霍奥拉韦岛（Kahoolawe）展开调查。相关训练活动包括"Koa Kai"演习与"环太平洋"军事演习（Rim of the Pacific, 简称RIMPAC），二者均使用了中频主动声呐，其中RIMPAC演习还动用了爆炸物。"Koa Kai"演习主要于2014年1月24日至31日，在夏威夷考艾岛与尼豪岛（Niihau）之间的太平洋导弹靶场设施巴金桑兹战术水下靶场及巴金桑兹水下靶场扩展区举行。"Koa Kai"演习结束后，调查团队于1月31日与2月5日开展了沿岸调查。RIMPAC演习的举办周期为2014年7月8日至8月2日，作业范围覆盖夏威夷主岛周边更广海域。RIMPAC演习后的航空沿岸调查于8月1日、4日至6日分4天完成，环绕前述5座岛屿开展。所有调查均以搜寻搁浅或近搁浅海洋哺乳动物为目标，观察员记录了离岸3公里范围内所有观测到的海洋哺乳动物与海龟的位置及行为。本次调查使用的平台为Aero Commander 500小型固定翼飞机。本项工作依据HDR任务订单KB26执行（不定额不定交付合同（Indefinite Delivery Indefinite Quantity, IDIQ）编号N62470-10-D-3011，美国海军设施工程司令部大西洋分部（NAVFAC LANT））。
