Satellite tracks of humpback whales generated from tag deployments during the Antarctic Whale Expedition (AWE) 2009/10

Satellite derived tracks of humpback whales tagged on their Antarctic feeding grounds.Data can be found here: https://data.aad.gov.au/aadc/argos/display_campaign.cfm?campaign_id=83Satellite tags were deployed on adult humpback whales with a modified version of the Air Rocket Transmitter System (ARTS, Restech) and a purpose-designed projectile carrier at a pressure of 7.5 – 10 bar. A custom-designed, 80mm anchor section is attached to a stainless steel cylindrical housing containing a location-only transmitter (SPOT-5 by Wildlife Computers, Redmond, Washington, USA and Kiwisat 202 Cricket by Sirtrack, Havelock North, New Zealand). This superseded anchor design resulted in the anchor section disarticulating upon deployment in order to achieve improved tag retention times while minimising impact. The tags were sterilised with ethylene oxide prior to deployment and implanted up to 290mm into the skin, blubber, interfacial layers and outer muscle mass of the whale. Tags were programmed to transmit to the Argos satellite system at various duty cycles and repetition rates for a maximum of 720 transmissions per day. These transmissions are relayed to processing centres which calculate the transmitter’s location by measuring the Doppler Effect on transmission frequency.

本数据集收录了在南极觅食场所标记的座头鲸卫星追踪轨迹。相关数据可通过以下链接获取：https://data.aad.gov.au/aadc/argos/display_campaign.cfm?campaign_id=83。研究人员采用改装版空气火箭发射器系统（Air Rocket Transmitter System, ARTS, Restech）与定制抛射载体，以7.5–10巴的压力将卫星标签部署于成年座头鲸身上。定制的80毫米锚定部件被安装于不锈钢圆柱形外壳上，该外壳内置仅支持定位功能的发射器：美国华盛顿州雷德蒙德市Wildlife Computers公司生产的SPOT-5，以及新西兰哈夫洛克北市Sirtrack公司生产的Kiwisat 202 Cricket。该迭代升级后的锚定设计可在部署时实现锚定部件自动脱开，以此在提升标签留存时长的同时最大限度降低对鲸鱼的影响。标签在部署前会通过环氧乙烷（ethylene oxide）进行灭菌处理，并被植入鲸鱼的皮肤、鲸脂、界面层以及外层肌肉组织中，植入深度可达290毫米。标签被编程为以多种占空比与重复速率向Argos卫星系统（Argos Satellite System）传输信号，单日最大传输次数为720次。这些传输信号会被中继至数据处理中心，处理中心通过测量传输频率的多普勒效应（Doppler Effect）来计算发射器的位置。
