Support for Publication Costs, American Society of Limnologyand Oceanography Symposium, What Controls Phytoplankton ___ Production in Nutrient-Rich Area of the Open Ocean

多年来，公海某些区域的高营养物质/低浮游植物种群的明显悖论一直困扰着海洋学家。解释它的假设包括光、温度、浮游动物放牧以及这些地区的痕量金属限制和/或毒性对生产力的调节。到目前为止，没有一个假说或它们的组合成为被广泛接受的解释，解释为什么这些海洋区域的氮和磷没有枯竭。最近，新的证据支持了这样的假设，即铁缺乏限制了亚北极和南极水域浮游植物的生长。这一证据引发了关于用铁给部分海洋施肥的可行性的讨论，从而将更多的大气二氧化碳隔离在未来几个世纪将被束缚的深海中。围绕这一命题的经济、社会和伦理问题，以及悬而未决的科学问题，证明有理由对这些地区的生产力调控这一主题进行严格的讨论、辩论和出版。为此，美国湖泊和海洋学学会(ASLO)举办了一次专题讨论会，主题是“是什么控制了公海营养丰富地区的浮游植物？”ASLO现在寻求资金，以支付出版一期湖沼学和海洋学专题讨论会的费用，以提供专题讨论会会议记录的书面记录。

The apparent paradox of high nutrients/low phytoplankton populations in some areas of the open ocean has challenged oceanographers for many years. Hypotheses to explain it include the regulation of productivity by light, temperature, zooplankton grazing, and trace metal limitation and/or toxicity in these regions. To date, none of the hypotheses, or combinations thereof, has emerged as a widely accepted explanation for why the nitrogen and phosphorus are not depleted in these areas of the oceans. Recently, new evidence has supported the hypothesis that iron deficiency limits phytoplankton growth in Subarctic and Antarctic waters. This evidence has stimulated discussions of the feasibility of fertilizing parts of the oceans with iron, and thus sequestering additional atmospheric CO2 in the deep oceans where it would be bound over the next few centuries. The economic, social, and ethical issues surrounding such a proposition, along with the outstanding scientific issues, justify rigorous discussion, debate, and publication on the topic of regulation of productivity in these regions. To this end, The American Society of Limnology and Oceanography (ASLO) held a symposium on the topic of "What controls phytoplankton in nutrient-rich areas of the open sea?" ASLO now seeks funding to cover the costs of publishing a special symposium issue of Limnology and Oceanography, to provide a written record of the symposium proceedings.
