Argos PTT Tracking Database

A repository of all ARGOS satellite messages from 1982 to present. Trackers have been used on AWS stations, buoys and numerous species of whales, seals and seabirds.ARGOS is a means of sending data back from PTT devices - Position Tracking Terminals. However, the subject does not necessarily have to be moving - as in the case of the Automatic Weather Stations (AWS), which use ARGOS for relaying meteorological data back to Australia.Animal species that have been or are currently monitored by the Australian Antarctic Program using the ARGOS system include:Grey-headed AlbatrossBlack-browed AlbatrossLight mantled sooty albatrossAustralian Fur SealAntarctic Fur SealWeddell SealRoss sealCrabeater sealSouthern Elephant SealEmperor PenguinKing PenguinMacaroni PenguinAdelie PenguinPygmy Blue WhaleLocations in which the ARGOS system is/was being used by the Australian Antarctic Program are:Admiralty BayAlbatross IslandAlmagroAuster RookeryBechervaise IslandCape GantheaumeCaroline CoveCaseyDavisDiego RamirezDumont d'Urville, BaseEdmonson PointIldefonsoInexpressible IslandMacquarie IslandMagnetic IslandPedra BrancaScullin MonolithShirley IslandSpit BayTaylor RookeryUfs IslandEach day, data is retrieved via telnet client from the ARGOS site in France. A batch process parses the data files and inserts into the Data Centre database by 0800 local time. End-users can subscribe to an email describing the recent data uploads. Web-based tools are provided to filter the data by bounding box, time span and type of message quality. Finally a optional velocity filter can be applied to remove spurious positions that should not be reachable by that particular species. For example, seal data can be filtered for positions that would require speeds in excess of 10 km/hr. The same tool ascribes species, gender, age class and breeding status to each set of data. A separate control allows the filtered data to be published to the general public and/or to OBIS and GBIF via web services.Output products include maps, excel spreadsheets and KML files for mapping data on Google Earth.

本数据集收录了1982年至今的所有ARGOS卫星报文。其配套追踪设备已部署于自动气象站（Automatic Weather Stations, AWS）、浮标以及多种鲸类、海豹和海鸟身上。

ARGOS系统是一种从位置跟踪终端（Position Tracking Terminals, PTT）回传数据的通信手段。但监测对象未必处于移动状态——例如使用ARGOS系统向澳大利亚中继气象数据的自动气象站（AWS）即是如此。

澳大利亚南极项目使用ARGOS系统监测过或正在监测的动物物种包括：灰头信天翁、黑眉信天翁、浅斑乌信天翁、澳洲海狗、南极海狗、威德尔海豹、罗斯海豹、食蟹海豹、南象海豹、帝企鹅、王企鹅、马可罗尼企鹅、阿德利企鹅、小蓝鲸。

澳大利亚南极项目使用过或正在使用ARGOS系统的监测地点包括：阿德默勒尔蒂湾、信天翁岛、阿尔马格罗、奥斯特企鹅聚居地、别切维尔塞岛、甘捷奥姆角、卡罗琳湾、凯西科考站、戴维斯科考站、迭戈拉米雷斯、迪蒙·迪维尔基地、埃德蒙森角、伊尔丰索岛、难言岛、麦夸里岛、磁岛、佩德拉布兰卡岩、斯克林巨岩、雪莉岛、斯皮特湾、泰勒企鹅聚居地、乌夫斯岛。

每日，系统通过Telnet客户端从法国的ARGOS站点获取数据。批处理程序将解析数据文件，并于当地时间08:00前将数据写入数据中心数据库。终端用户可订阅用于推送近期数据上传情况的邮件。平台提供基于网页的工具，支持通过边界框（bounding box）、时间跨度和报文质量类型对数据进行筛选。此外还可启用可选的速度过滤器，剔除特定物种无法达到的异常位置数据——例如针对海豹数据，可过滤掉需要其移动速度超过10公里/小时的位置点。同一工具可为每一组数据赋予物种、性别、年龄层级及繁殖状态属性。另有独立控件支持将筛选后的数据通过网页服务发布至公众平台，或同步至海洋生物地理信息系统（Ocean Biogeographic Information System, OBIS）与全球生物多样性信息机构（Global Biodiversity Information Facility, GBIF）。

产出成果包括地图、Excel电子表格以及可用于在谷歌地球（Google Earth）上可视化数据的关键标记语言（Keyhole Markup Language, KML）文件。
