This grant is in partial support of a workshop on wetlands mitigating water quality problems. The workshop will be held on August 3, 2019 on the shores of Lake Erie in north central Ohio, The workshop will include presentations on early research results from ongoing wetlaculture experiments in Ohio and south Florida, the role of wetlands in mitigating algal toxicity, current studies of large-scale wetland restoration and creation of wetlands for water quality control, as well as studies by a UNESCO lab in Poland on ecohydrological approaches to dealing with harmful algal blooms. Landscape-scale approaches are needed that integrate wetland retention of nutrients from stormwater and polluted rivers and ditches with a recycling mechanism that will return those nutrients to agricultural production, thereby decreasing downstream eutrophication, including harmful algal blooms and hypoxia, while reducing the requirements for additional fertilization for agricultural production.Treatment wetlands in high-nutrient landscapes integrate food (agricultural production), energy (solar-based ecological systems replacing fossil-fuel-based treatment systems) and water (water quality improvement. The western basin of Lake Erie will be the feature of several of the presentations and probably most of the discussion at our workshop. It has suffered extensive late summer algal blooms for the past seven years, starting with the then-largest recorded algal bloom in Lake Erie in 2011 and leading to a total shutdown of the Toledo Ohio water supply in 2014. Subsequently, one of the most extensive algal blooms occurred in 2017 in Lake Erie. Restoration of some of the former Black Swamp of northwestern Ohio has now been proposed for the strategic purpose of reducing nutrient inflows to the western basin of Lake Erie. There are many scientific inquiries that need to be implemented before the feasibility of a restoration on this scale can be attempted. Research is needed on wetland design in this former-wetland landscape, and on whether the wetlaculture approach would work well in this region. This workshop will focus on identifying and articulating the required research needs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这笔赠款是为了部分支持一个关于湿地缓解水质问题的研讨会。研讨会将于2019年8月3日在俄亥俄州中北部的伊利湖畔举行，研讨会将介绍俄亥俄州和佛罗里达州南部正在进行的湿地养殖实验的早期研究结果，湿地在减轻藻类毒性方面的作用，大规模湿地恢复和创建用于水质控制的湿地的当前研究，以及联合国教科文组织在波兰的一个实验室关于处理有害藻华的生态水文学方法的研究。需要采取景观规模的办法，将湿地对雨水、受污染的河流和沟渠中的养分的保持与将这些养分返回农业生产的循环机制结合起来，从而减少下游的富营养化，包括有害的藻华和缺氧，同时减少对农业生产额外施肥的需求。伊利湖西部盆地将是我们研讨会上几个演讲的特色，可能也是大部分讨论的特色。在过去的七年里，它遭受了夏末大规模的藻类水华，从2011年伊利湖有记录以来最大的藻类水华开始，并导致2014年俄亥俄州托莱多的供水完全中断。随后，2017年伊利湖出现了最广泛的藻类水华之一。出于减少营养物质流入伊利湖西部盆地的战略目的，现已提议修复俄亥俄州西北部的一些以前的黑色沼泽。在尝试这种规模的修复可行性之前，需要进行许多科学调查。需要研究在这一前湿地景观中的湿地设计，以及湿地养殖方法是否在该地区发挥良好作用。本次研讨会将集中于确定和阐明所需的研究需求。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
