Cuvier's Beaked Whale and Fin Whale Surveys at the Southern California Offshore Anti-submarine Warfare Range (SOAR)

Original provider: Marine Ecology and Telemetry Research Dataset credits: Marine Ecology and Telemetry Research Abstract: The United States (US) Navy uses the Southern California (SOCAL) portion of the Hawaii-Southern California Training and Testing area, a collection of nearshore and offshore training areas that include much of the navigable water from Santa Barbara Island, California, to northern Baja California, Mexico, and extending several hundred miles to the west. It is among one of the most heavily used tactical training areas in the world, and is used for a variety of aerial, surface, and subsurface exercises. The Southern California Offshore Range (SCORE) is a subset of complexes within SOCAL centered on San Clemente Island and managed via the Range Operation Center (ROC) on North Island, Coronado. It includes the Southern California Anti-submarine Warfare Range (SOAR), a focal area for exercises involving mid-frequency active sonar (MFAS) systems within the San Nicolas Basin. Through its N45 Living Marine Resources (LMR) research programs, and more recently in support of Pacific Fleet Monitoring efforts, the US Navy has funded directed studies on cetacean occurrence on SOAR since 2006. The primary focus of these studies is to support long-term surveys of Cuvier’s beaked whales and fin whales using photo-identification (photo-ID) and genetics to elucidate population size, structure, and trends, which can in turn provide a particularly robust basis for assessing population-level impacts of Navy training. Data is collected on all species encountered in this region as part of the monitoring program.原始提供方：海洋生态学与遥测研究机构 数据集署名：海洋生态学与遥测研究机构 摘要：美国海军使用夏威夷-南加州训练与测试区域的南加州（SOCAL）部分。该区域由近岸与近海训练区组成，覆盖从加利福尼亚州圣巴巴拉岛至墨西哥下加利福尼亚州北部的大部分可通航水域，并向西延伸数百海里。它是全球使用频次最高的战术训练区域之一，可支撑各类空中、水面及水下演习任务。南加州近海靶场（SCORE）是SOCAL范围内的综合体子集，以圣克莱门特岛为核心，由科罗纳多北岛的靶场运营中心（ROC）负责管理。该靶场包含南加州反潜战靶场（SOAR），这里是圣尼古拉斯盆地内中频主动声呐（MFAS）系统相关演习的核心区域。 自2006年起，美国海军依托其N45海洋生物资源（LMR）研究计划，并为配合太平洋舰队监测工作，资助了针对SOAR海域鲸类出现情况的定向研究。此类研究的核心目标为：通过照片识别（photo-ID）与遗传学技术，对居维叶喙鲸及长须鲸开展长期调查，以明确其种群规模、结构与动态趋势，进而为评估海军训练活动带来的种群级影响提供坚实的科学依据。作为该监测计划的组成部分，项目组会收集本区域内所有被观测到的鲸类物种的相关数据。
