Parent metadata record for all metadata created from the SIPEX II voyage of the Aurora Australis, 2012-2013 season - Sea Ice Physics and Ecosystem eXperiment

More than 50 scientists from eight countries conducted the Sea Ice Physics and Ecosystem eXperiment 2012 (SIPEX-2). The 2012 voyage built on information and observations collected in 2007, by re-visiting the study area at about 100-120 degrees East. This was the culmination of years of preparation for the Australian Antarctic Division and, more specifically, the ACE CRC sea-ice group who lead this international, multi-disciplinary, sea ice voyage to East Antarctica.Work began at the sea-ice edge and penetrated the pack ice towards the coastal land-fast ice. The purpose of SIPEX-2 was to investigate relationships between the physical sea-ice environment, marine biogeochemistry and the structure of Southern Ocean ecosystems. While the scientists and crew did not set foot on Antarctic terra firma, a number of multi-day research stations were set up on suitable sea ice floes, and a range of novel and state-of-the-art instruments were used. These included:A Remotely Operated Vehicle (ROV) to observe and film (with an on-board video camera) krill, and to quantify the distribution and amount of sea ice algae associated with ice floes.An Autonomous Underwater Vehicle (AUV) to study the three-dimensional under-ice topography of ice floes.Helicopter-borne instruments to measure snow and ice thickness, floe size and sea ice type. Instruments included a scanning laser altimeter, infrared radiometer, microwave radiometer, camera and GPS.Sea ice accelerometer buoys to measure sea ice wave interaction and its effect on floe-size distribution.Customised pumping systems and light-traps to catch krill from below the ice and on the sea floor.Available at the provided URL in this record, is a link to a file containing the locations of all ice stations from this voyage.

来自8个国家的50余名科学家开展了2012年海冰物理与生态实验（Sea Ice Physics and Ecosystem eXperiment 2012，简称SIPEX-2）。本次2012年科考航次以2007年收集的观测数据与资料为基础，重新造访了东经100°至120°左右的研究区域。这是澳大利亚南极署（Australian Antarctic Division），尤其是牵头本次国际多学科南极东向海冰科考航次的ACE CRC海冰研究团队，历经多年筹备的成果。科考工作从海冰边缘起步，向沿岸固定冰方向穿透流冰群。SIPEX-2的核心目标为探究海冰物理环境、海洋生物地球化学与南大洋生态系统结构之间的相互关联。尽管科考人员与船员并未踏足南极大陆陆地，团队仍在合适的海冰浮冰上搭建了多个多日科考站，并运用了一系列新颖顶尖的观测仪器，具体包括：遥控水下机器人（Remotely Operated Vehicle，ROV），搭载机载摄像机用于观测并拍摄磷虾，同时量化与浮冰相关的海冰藻类的分布与数量；自主水下航行器（Autonomous Underwater Vehicle，AUV），用于研究浮冰的三维冰下地形；机载直升机探测仪器，用于测量雪厚、冰厚、浮冰尺寸与海冰类型，所用仪器涵盖扫描激光高度计、红外辐射计、微波辐射计、摄像机与GPS（Global Positioning System）；海冰加速度计浮标，用于测量海冰与波浪的相互作用及其对浮冰尺寸分布的影响；定制抽滤系统与光阱装置，用于从冰下与海底捕获磷虾。本记录提供的URL链接包含本次航次所有冰上科考站的位置信息。
