Determination of the Redfield Remineralization Ratios Based on Neutral Surface Analysis of the New Global Data Set

在这项研究中，来自普林斯顿大学和俄勒冈州立大学的研究人员将利用NOAA-OACES和WOCE实地研究中获得的新的高质量营养数据集，来精确估计海洋有机质分解或再矿化过程中产生的磷、氮和碳的相对数量，即所谓的Redfield比率（P:N:C）。红场比率并不是一个新概念；事实上，它已经被使用了几十年，它的近似值也已经知道了。海洋科学家依靠该比率的估计值，从已测量的值中计算出各种未测量的生物地球化学值。对近年来产生的高质量营养数据集的分析要求雷德菲尔德的估计得到改进，这正是该研究小组打算做的。还将开发一种最佳的多参数技术，以确定比值端点，用于在联合全球海洋通量研究（JGOFS）期间以及从OACES和WOCE收集的生物地球化学数据建模。该技术将应用于每个海洋盆地的20个中性密度层，以获得全球变率以及全球平均雷德菲尔德值的一些概念。

ABSTRACTOCE-9819144 / OCE-9903391In this study, investigators from Princeton University and Oregon State University will use the new, high-quality nutrient data set obtained during NOAA-OACES and WOCE field studies to refine estimates of the relative amounts of phosphorous, nitrogen, and carbon generated during the decomposition, or remineralization, of marine organic matter - the so-called Redfield Ratio (P:N:C). The Redfield Ratio is not a new concept; in fact, it has been used, and its approximate value has been known, for decades. Ocean scientists have relied on estimates of the Ratio to calculate a values of a variety of unmeasured biogeochemical values from the values of ones that have been measured. Analysis of the high-quality nutrient data sets generated in recent years demands that the Redfield estimate be improved, and this is what this team of investigators intends to do. An optimal multi-parameter technique will also be developed to determine ratio endpoints for application to modeling of biogeochemical data collected during the Joint Global Ocean Flux Study (JGOFS) as well as from OACES and WOCE. The technique will be applied to twenty neutral-density layers in each ocean basin to achieve some idea of the global variability as well as a global averaged Redfield value.
