Sea Ice Atlas from Advanced Very High Resolution Radiometer (AVHRR) imagery 1992-1999

This Atlas presents a compilation of AVHRR satellite images of sea ice adjacent to the coast of Eastern Antarctica. It is produced primarily for use by marine and vertebrate ecologists within the Australian Antarctic Division and as a contribution to the CCAMLR Ecosystem Monitoring Program. It is anticipated that this atlas will have value to a wider range of research and other uses including shipping operations.The Atlas provides one good image for each month between 1992 and 1999 for each of 5 regions of Eastern Antarctica centered on the following Antarctic Stations.Mawson station (M) - latitude 67 degrees 36.3 minutes S, longitude 62 degrees 52.2 minutes EDavis station (D) - latitude 68 degrees 34.6 minutes S, longitude 77 degrees 58.3 minutes ECasey station (C) - latitude 66 degrees 17.0 minutes S, longitude 110 degrees 31.2 minutes EDumont D'Urville station (DD) - latitude 66 degrees 39.8 minutes S, longitude 140 degrees 00.1 minutes ETerra Nova Bay station (TN) - latitude 74 degrees 41.7 minutes S, longitude 164 degrees 07.0 minutes EEach image has been renavigated onto the same projection (Polar stereographic), gridded and a coastline added. Visible and thermal images are provided for the austral summer months, while only a thermal image is provided for the dark winter months. Due to either missing data or the lack of suitable imagery it has not been possible to provide a complete coverage over the period in all regions. Those 500 images presented were culled from some 20,000 images consulted.Images are presented with a schematic map indicating the major divisions of the image into open water, sea ice, cloud, land etc. Each month is accompanied by a short description of the sea ice conditions.The concept of a Sea Ice Atlas for scientific purposes was first proposed in 1999 and funded by the Australian Antarctic Division on the recommendation of the ANARE Mapping and Geographic Information Committee in 1999. Dr Kelvin Michael at IASOS was contracted to supervise the project and produce the Sea Ice Atlas in both hard copy and digital format.The AVHRR data are down loaded at the HRPT receiving facility Australian Antarctic Station of Casey. The HRPT archive is kept at the Antarctic Climate and Ecosystems CRC at the University of Tasmania.本图集汇编了东南极洲沿岸邻近海域的高级甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR）卫星影像。本图集主要面向澳大利亚南极局（Australian Antarctic Division, AAD）的海洋与脊椎动物生态学家使用，同时作为对南极海洋生物资源保护委员会（Commission for the Conservation of Antarctic Marine Living Resources, CCAMLR）生态监测计划的一项贡献。本图集预计可服务于更广泛的研究与其他领域，包括航运作业。 本图集覆盖东南极洲5个以南极科考站为中心的区域，为1992年至1999年间的每个月份各提供一幅优质影像，各区域的中心科考站如下： 莫森站（M）：南纬67°36.3′，东经62°52.2′； 戴维斯站（D）：南纬68°34.6′，东经77°58.3′； 凯西站（C）：南纬66°17.0′，东经110°31.2′； 迪蒙·迪尔维尔站（DD）：南纬66°39.8′，东经140°00.1′； 特拉诺瓦湾站（TN）：南纬74°41.7′，东经164°07.0′。 所有影像均已重新投影至统一的极立体投影（Polar stereographic），并完成网格化处理，同时添加了海岸线图层。南半球夏季月份会同时提供可见光与热红外影像，而极夜冬季仅提供热红外影像。由于存在数据缺失或缺乏合格影像的情况，部分区域在部分时段无法提供完整的影像覆盖。本次收录的500幅影像均从约20000幅检索到的影像中精选而来。 每幅影像均附带示意图，标注了影像中开阔水域、海冰、云、陆地等主要地物分区。每个月份的影像均附带一段海冰状况的简要说明。 面向科学用途的海冰图集概念最早于1999年提出，并于同年经澳大利亚南极探险队（Australian National Antarctic Research Expeditions, ANARE）测绘与地理信息委员会建议，由澳大利亚南极局资助立项。IASOS的凯尔文·迈克尔博士受委托主持该项目，并制作了印刷版与数字版海冰图集。 AVHRR数据通过凯西站的高分辨率图片传输（High Resolution Picture Transmission, HRPT）接收站进行下载。HRPT数据档案由塔斯马尼亚大学南极气候与生态系统合作研究中心（Antarctic Climate and Ecosystems CRC）保管。
