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 E Davis station (D) - latitude 68 degrees 34.6 minutes S, longitude 77 degrees 58.3 minutes E Casey station (C) - latitude 66 degrees 17.0 minutes S, longitude 110 degrees 31.2 minutes E Dumont D'Urville station (DD) - latitude 66 degrees 39.8 minutes S, longitude 140 degrees 00.1 minutes E Terra Nova Bay station (TN) - latitude 74 degrees 41.7 minutes S, longitude 164 degrees 07.0 minutes E Each 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.本图集汇编了南极东部沿岸毗邻海域的先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）卫星海冰影像。本图集主要面向澳大利亚南极局的海洋与脊椎动物生态学者开发，同时作为贡献成果纳入南极海洋生物资源养护委员会（Commission for the Conservation of Antarctic Marine Living Resources，CCAMLR）生态系统监测计划。本图集预期可服务于更广泛的科研与其他场景，包括航运作业。 本图集为1992年至1999年间的每个月份，在以下5个以南极科考站为中心的南极东部区域各提供一幅优质影像： 莫森站（Mawson station，M）：南纬67°36.3′，东经62°52.2′ 戴维斯站（Davis station，D）：南纬68°34.6′，东经77°58.3′ 凯西站（Casey station，C）：南纬66°17.0′，东经110°31.2′ 迪蒙·迪维尔站（Dumont D'Urville station，DD）：南纬66°39.8′，东经140°00.1′ 特拉诺瓦湾站（Terra Nova Bay station，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地方位等距投影（Polar stereographic），并进行网格化处理，同时添加了海岸线图层。南极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。由于部分数据缺失或无可用合格影像，部分区域在对应时段未能完成完整影像覆盖。本图集收录的500幅影像均从约20000幅候选影像中遴选而来。 每幅影像均附带示意图，标注出影像内开阔水域、海冰、云、陆地等主要分区；每个月份的影像还配有海冰状况简要说明。 科学用海冰图集的构想最早于1999年提出，并于同年经澳大利亚国家南极研究探险队（Australian National Antarctic Research Expeditions，ANARE）测绘与地理信息委员会提议，由澳大利亚南极局资助立项。澳大利亚南极与南大洋研究所（Institute of Antarctic and Southern Ocean Studies，IASOS）的开尔文·迈克尔博士获聘负责该项目监管，并完成了印刷版与数字版海冰图集的制作。 AVHRR数据通过凯西站的高分辨率图片传输（High Resolution Picture Transmission，HRPT）接收站获取。HRPT影像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托管。
