Satellite tracking of southbound East Australian humpback whales 2008/09

Tracking spring and summer migration of humpbacks from Eden NSW, Australia to Antarctica. Dataset can be found here: https://data.aad.gov.au/aadc/argos/display_campaign.cfm?campaign_id=70 Satellite 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 This superseded anchor design resulted in the anchor section disarticulating upon deployment in order to achieve improved tag retention times while minimising impact.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.追踪座头鲸于春夏季从澳大利亚新南威尔士州伊甸镇至南极洲的迁徙活动。 本数据集可通过以下链接获取：https://data.aad.gov.au/aadc/argos/display_campaign.cfm?campaign_id=70 研究人员采用经改装的空气火箭发射系统（Air Rocket Transmitter System, ARTS，Restech公司出品）与定制设计的抛射载体，以7.5至10巴的压力，将卫星标签部署于成年座头鲸身上。定制设计的80毫米锚定段安装于不锈钢圆柱形外壳之上，该外壳内置仅用于定位的发射器：美国华盛顿州雷德蒙德市Wildlife Computers公司的SPOT-5，以及新西兰哈夫洛克北市Sirtrack公司的Kiwisat 202 Cricket。 这款经过升级的锚定设计可在部署时实现锚定段脱离，以此在提升标签留存时长的同时尽可能降低对鲸鱼的影响。 标签在部署前会通过环氧乙烷进行灭菌处理，并被植入鲸鱼皮肤、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和重复频率向Argos卫星系统传输数据，单日最大传输次数可达720次。这些传输信号会被转发至数据处理中心，后者通过测量传输频率的多普勒效应来计算发射器的位置。
