Ship-board webcam images taken during the SIPEX II voyage of the Aurora Australis, 2012

This dataset contains webcam images from the three ship-board webcams that were present during the SIPEX II voyage to the sea ice North-East of Casey station, from Hobart in September to November 2012.

The ship had webcams mounted on the bridge (facing foreward), the top of the helicopter hangar (facing aft), and the port-side bridge wing (facing portside).

Images were taken from each camera every ten minutes.

File names consist of which webcam the image was from, followed by an 8 digit date (YYYYMMDD), followed by a sequence number.

The folder structure consists of {YEAR}/{WEEK_NUMBER}/{DAY}.

The port-side webcam was enabled during the second ice station, so earlier images do not exist. The port side webcam does show a good overview of the activities at each ice station, as well as transits between ice stations. The aft camera recorded pictures of helicopter operations as well as the path of destruction that the ice breaker left in its wake. The fore camera shows a clear picture of ice conditions from the point of view of the bridge (in good weather).

The webcams were set up and maintained by Matthew Longmire and Ian McClean of the AAD.

本数据集包含2012年9月至11月期间，从霍巴特（Hobart）出发前往凯西站（Casey Station）东北方向海冰区域的SIPEX II科考航次中，船舶搭载的三台网络摄像头（webcam）所拍摄的影像。
该船舶分别在驾驶台（朝前）、直升机机库顶部（朝后）以及左舷驾驶台翼台（朝向左舷）安装了网络摄像头。
每台网络摄像头每隔10分钟采集一张影像。
影像文件名由拍摄源摄像头标识、8位日期（格式为YYYYMMDD）以及序列号依次拼接而成。
数据集的文件夹结构遵循「{YEAR}/{WEEK_NUMBER}/{DAY}」的层级格式。
左舷网络摄像头仅在第二个冰站期间启用，因此该摄像头无早期拍摄影像。其可清晰记录各冰站的作业全貌，以及冰站间的航行轨迹。
船尾网络摄像头记录了直升机作业画面，以及破冰船航行后留下的冰面破坏航迹。
朝前的网络摄像头则可在天气良好时，从驾驶台视角呈现清晰的海冰状况。
本数据集的网络摄像头由澳大利亚南极局（Australian Antarctic Division, AAD）的Matthew Longmire与Ian McClean架设并维护。
