9416614 Ammerman The principal objective of this study is to determine if planktonic microbial growth in the Sargasso Sea is phosphorus limited. This objective will be addressed by a combination of chemical, metabolic and biomass measurements coupled with a series of nutrient-enrichment experiments. The measurements will made over the course of three cruises aimed at capturing contrasting spring bloom and summer periods. More frequent time series cruises will supplement the results fro these three proposed study will measure the cycling of phosphorus in the Sargasso Sea, which is a major but rarely studied nutrient which may be limiting autotrophic and heterotrophic planktonic growth. Phosphorus limitation in such environments could have significant impact on the global phosphorus cycle and the oceanic component of the global carbon cycle. The research will also serve to improve analytical methods for measuring inorganic phosphorus in seawater.

小行星9416614 本研究的主要目的是确定是否在马尾藻海浮游微生物的生长是磷限制。 这一目标将通过结合化学、代谢和生物量测量以及一系列营养强化实验来实现。 测量将在三次巡航过程中进行，旨在捕捉对比鲜明的春季开花和夏季。 更频繁的时间序列巡航将补充这三项拟议研究的结果，将测量马尾藻海中磷的循环，这是一种主要但很少研究的营养物质，可能限制自养和异养浮游生长。 在这样的环境中限制磷可能会对全球磷循环和全球碳循环的海洋组成部分产生重大影响。 该研究还将有助于改进测量海水中无机磷的分析方法。
