中文摘要
如果没有科学家的帮助, 知道为什么主要营养素永远不会耗尽, 离岸的开放海洋沃茨。 马丁博士建议测试 南大洋浮游植物生产力假说 与铁的供应量直接相关。 的待测样品 这一假设是在公海沃茨收集的, 1989年3月/4月在德雷克海峡和1989年在罗斯海 1990年1月/2月。 初步结果表明,铁 缺乏是浮游植物无法 大量繁殖并消耗南大洋沃茨的主要营养物质。 延长一年的资金,以支持我们继续分析 样品和缺铁假说的测试是必需的 在这个提议中。
英文摘要
The Southern Ocean will never be adequately understood without knowing the reasons why major nutrients never go to depletion in offshore, open-ocean waters. Dr. Martin proposes to test the hypothesis that phytoplankton productivity in the Southern Ocean varies in direct relation to iron availability. Samples to test this hypothesis were collected in the open-ocean waters of the Drake Passage in March/April 1989 and in the Ross Sea in January/February 1990. Initial results suggest that iron deficiency is the primary reason that the phytoplankton fail to bloom and use up major nutrients in offshore Southern Ocean waters. Renewed funding for one year to support our continued analysis of samples and testing of the iron deficiency hypothesis is requested in this proposal.
