Southern Ocean IronExIII: Science and Logistics Workshop

摘要OCE-9817821直到过去四年，海洋科学家才证实，在表层海水中溶解的超微量铁可能会限制世界海洋广大地区的生物生产，特别是那些远离大陆的低产量地区，那里的其他营养物质(如氮和二氧化硅)似乎过剩。自从这组调查人员和他们的同事--IronEx I和IronEx II实验--在赤道西太平洋验证了“铁假说”以来，人们一直在兴奋地猜测，应该出现铁限制的主要海洋区域是南大洋，特别是在南极洲附近的高纬度地区。该奖项的目的是支持南大洋“IronEx III”的规划和评估研讨会。被邀请的参与者名单将包括几乎整个美国铁生物地球化学专家社区以及他们的顶级国际同行。

ABSTRACT OCE-9817821 It has only been within the past four years that ocean scientists have verified that the ultratrace amounts of iron dissolved in surface seawater may limit biological production throughout vast regions of the world ocean, particularly those low-production regions far from the continents where other nutrients (like nitrogen and silica) seem to be in excess. Since verification of the "iron hypothesis" in the Western Equatorial Pacific by this team of investigators and their colleagues - the IronEx I and IronEx II experiments - there has been excited speculation that the major oceanic region where iron limitation should occur is the Southern Ocean, particularly in the high latitudes near Antarctica. The purpose of this award is to support a planning and evaluation workshop for a Southern Ocean "IronEx III". The list of invited participants will include virtually the entire community of American iron biogeochemistry experts as well as their top international counterparts.
