SGER: Collaborative Research: Contribution of the 2008 Midwestern Flood to Gulf Hypoxia

CBET-0843792Schnoor 该 SGER 奖旨在表彰针对创纪录的中西部洪水的紧急研究，该洪水向墨西哥湾输送大量营养物质，加剧缺氧。 研究人员将通过综合自己和其他研究人员的监测数据，对洪水顶部的养分通量进行质量平衡。 他们确定并列出了关于海湾缺氧的发展和缓解仍然存在的关键科学问题，并制定了一个控制假设，即创纪录的洪水导致了营养物负荷峰值，进而导致有史以来最严重的海湾缺氧。他们的研究将检验这一假设。 墨西哥湾缺氧是美国许多地区景观和河流流域过量氮和磷输出造成的广泛沿海富营养化的典型现象。这项研究将在美国各地具有广泛的适用性，有助于了解洪水事件对营养驱动因素的作用，并可能在洪水高峰期间提出更有效的政策和管理策略。

CBET-0843792SchnoorThis SGER award is for urgent research in response to a record Midwestern flood that is contributing large fluxes of nutrients to the Gulf of Mexico, exacerbating hypoxia. The investigators will perform mass balances on nutrient fluxes along the crest of the flood by synthesizing their own monitoring data and that of other researchers. They have identified and listed key science questions that remain regarding the development and mitigation of Gulf Hypoxia, and have formulated a governing hypothesis that record flooding has caused peak nutrient loadings which will, in turn, cause the largest Gulf Hypoxia ever. Their research will test this hypothesis. Gulf of Mexico hypoxia is prototypical of widespread coastal eutrophication caused by excessive nitrogen and phosphorus export from landscapes and river basins in many regions of the U.S. The research will have wide applicability across the U.S. in helping to understand the role of flood events on nutrient drivers and possibly to suggest more effective policies and management strategies during peak flood events.
