Oden Southern Ocean 2008/09 - Meteorological, Oceanographic and Ship Data Collected Onboard Icebreaker Oden during November 2008 through January 2009

Oden Southern Ocean 2008/09 was a cooperative effort of the Swedish Polar Research Secretariat and the National Science Foundation (NSF) in the USA.

It was the third season in a row icebreaker Oden worked in Antarctica. The basis of the cooperative effort was that NSF chartered Oden from the Swedish Maritime Administration and the Swedish Polar Research Secretariat to break an ice channel to the McMurdo Antarctic Station in the Ross Sea, allowing supply vessels to reach the station. As Oden sailed through the Southern Ocean, researchers had an opportunity to perform marine studies.

The marine research conducted during Oden Southern Ocean 2008/09 was interdisciplinary, and involved environmental chemistry, chemical and physical oceanography, climate research, epidemiology and evolutionary biology. The scientific findings from the expedition will play an important role in our understanding of the Antarctic system and its role in climate change. Its extreme climate and isolated location makes the Antarctic a unique platform for studying the Earth’s climatic, biological and geological evolution, and the environmental problems of the future.

This data set contains meteorological, oceanographic and ship data collected during the American-Swedish expedition Oden Southern Ocean 2008/09, which was an international research cruise using the icebreaker Oden. The expedition embarked from Gothenborg, Sweden on October 28 2008 and arrived in McMurdo Januari 2009.

Data include meteorological variables: Air temperature, Humidity, Wind direction/speed, Atmospheric pressure.

Oceanographic variables: Sea water temperature, Conductivity, Salinity and Sound velocity.

Ship data: Position, Speed, Course.

Further metadata on instrumentation and the individual variables can be found in the info file. Graphics and files describing the route are included in the package.

Quality Information:

Obviously erroneous data (e.g. negative air pressure) have been omitted. No other processing or quality check of the data has been undertaken. Users should be aware of this in further data handling and analysis.

2008/2009年度奥德森号南大洋科考项目是瑞典极地研究秘书处（Swedish Polar Research Secretariat）与美国国家科学基金会（National Science Foundation, NSF）的合作项目。

本项目是破冰船奥德森号（Oden）连续第三个南极科考季。此次合作的核心内容为：美国国家科学基金会从瑞典海事管理局与瑞典极地研究秘书处租赁奥德森号，用于在罗斯海区域开辟通往麦克默多南极站（McMurdo Antarctic Station）的冰上航道，保障补给船舶能够顺利抵达该科考站。奥德森号在南大洋航行期间，科研人员得以开展海洋相关研究工作。

本次2008/2009年度奥德森号南大洋科考所开展的海洋研究具有跨学科特性，涵盖环境化学、化学与物理海洋学、气候研究、流行病学以及进化生物学等领域。本科考队的科研成果将有助于深化我们对南极系统及其在气候变化中作用的认知。南极拥有极端气候与与世隔绝的地理位置，是研究地球气候、生物与地质演化以及未来环境问题的独特平台。

本数据集收录了2008/2009年度奥德森号南大洋美瑞联合科考期间采集的气象、海洋学与船舶航行数据，本次科考为使用破冰船奥德森号开展的国际研究巡航。科考队于2008年10月28日从瑞典哥德堡出发，并于2009年1月抵达麦克默多南极站。

数据包含以下类别：
1. 气象变量：气温、湿度、风向/风速、大气压强；
2. 海洋学变量：海水温度、电导率、盐度与声速；
3. 船舶航行数据：位置、航速、航向。

关于仪器设备与各变量的详细元数据，可查阅数据包中的说明文档。数据包中还包含航线相关的图表与文件。

数据质量说明：
已剔除明显存在错误的数据（例如负大气压强值），未对其余数据进行额外处理或质量校验。使用者在后续的数据处理与分析过程中需注意此情况。
