中文摘要
0087530 Honjo拟议的工作将在澳大利亚南部的极锋区提供和维护一个深海沉积物收集器系泊系统,这是对澳大利亚南极合作研究中心在亚南极区部署的一个类似的澳大利亚沉积物收集器系泊系统的补充。 澳大利亚方案最近得到延长;这项建议工作将把联合工作延长两年,直到2003年。 具体目标是使用放射性核素技术检查颗粒物质的产生、再矿化和出口,以便评价沉积物收集器的效率。 另一个目标是记录在南部高纬度地区通风的中间深度水团是否可以为人为二氧化碳提供一个临时的替代物,并了解该地区在大气二氧化碳水平的长期趋势和年际变化中的作用。
英文摘要
0087530HonjoThe proposed work will provide and maintain of a deep sea sediment trap mooring in the Polar Frontal Zone south of Australia, which complements a similar Australian sediment trap mooring in the Subantarctic Zone deployed by the Australian Antarctic Cooperative Research Centre. The Australian program has recently been extended; this proposal work will extend the joint work for two years until 2003. The specific objective is to examine the production of particulate matter, remineralization, and export using a radionuclide technique that will allow the evaluation of sediment trap efficiency. A further objective is to document whether intermediate depth water masses that are ventilated at high southern latitudes can provide a temporary reservoirfor anthropogenic carbon dioxide, and to understand the role of this region in the long term trends and interannual variability of atmospheric carbon dioxide levels.
