Informing spatial planning for pygmy blue whale management: fine scale analysis of movement (WEL)

This project documents the results of a desk-top analysis of existing pygmy blue whale (PBW) satellite telemetry data (horizontal and vertical movement) at finer scales than previously undertaken. The objective was to provide key parameters on the movement behaviour of PBW within the North-west Marine Region (NWMR) to assist in understanding and modelling their potential responses to underwater noise in the region.Satellite tagged PBW (n=10) spent 19 ± 6 days in the region between Ningaloo and the northern extent of Australia’s EEZ on the northern migration (present 12 April – 12 July) and 23 and 10 days on the southern migration (present 23 September – 30 October)

本项目记录了针对现有小蓝鲸（pygmy blue whale, PBW）卫星遥测数据（涵盖水平与垂直运动数据）开展的桌面分析结果，该分析采用了较此前同类研究更为精细的尺度。本研究的目标为获取西北海域（North-west Marine Region, NWMR）内小蓝鲸的运动行为关键参数，以助力解析该海域内小蓝鲸对水下噪声的潜在响应并构建相关响应模型。本次研究中被卫星标记的小蓝鲸样本量为10头，其在北迁过程中（停留时段为4月12日至7月12日）于宁格鲁礁与澳大利亚专属经济区北部边界之间的海域停留了19±6天；在南迁过程中于该海域的停留时长分别为23天与10天，南迁的停留时段为9月23日至10月30日。
