The National Aeolian Detritus Project

国家风成碎屑项目（NADP）的本质非常简单——从天上掉下来的是什么？这意味着什么？中学生和大学生们正在一个2.3平方米的塑料水池上收集空气中的微粒。他们用法医证据胶带从收集器中去除颗粒，并将其集中在过滤器上进行检查。简单的光学显微镜是最有用的鉴定技术，在大多数情况下，只需要一个图像参考进行鉴定。NADP中心通过我们的网站www.skydust.org协助收集站点，提供颗粒图像的在线目录，安排先进的识别技术，并根据每个站点的情况开发科学有效的查询线。会员网站收集的数据以地理空间信息系统格式公布在我们的网站上，任何人都可以查阅。我们的收集程序不是特定类型的，总是捕获植物和动物生物制剂和陆地矿物组分。化学微粒和微陨石的发现频率较低。因此，这些集合提供了一个调查线几乎任何课堂目的或课程。我们与NASA太空基金的初步工作已经显示出与亚洲尘埃输送的复杂研究有很好的相关性，这表明我们的研究可以用作火星沙尘暴调查的代理。该项目为最佳实践提供了高度激励和易于采用的方法，大力支持基于标准的科学课程，并为城市和代表性不足的学生群体提供了便利。

The essence of the National Aeolian Detritus Project (NADP) is disarmingly simple - what falls out of the sky and what does it mean? Middle school through college students are collecting airborne particulate on a 2.3 square meter sheet of coated nylon draped in a plastic wading pool. They remove particulate from the collector with forensic evidence tape and concentrate it on filters for examination. Simple light microscopy is the most useful identification technique and, in most cases, requires only an image reference for identification. The NADP center is assisting collecting sites through our website, www.skydust.org, by providing an on-line catalog of particulate images, arranging advanced identification techniques, and developing scientifically valid lines of inquiry tailored to the circumstances of each site. Data collected by member sites are published on our website in Geospatial Information Systems format and can be accessed by anyone. Our collecting procedure is not type-specific and invariably captures plant and animal biologicals and terrestrial mineral fractions. Chemical particulate and micrometeorites are found less frequently. Thus these collections offer a line of inquiry for almost any classroom purpose or curriculum. Our preliminary work with NASA Space Grant has shown good correlation with sophisticated studies of Asian dust transport, suggesting that our studies can be used as proxies for the investigation of Martian dust storms. This project offers a highly motivating and easily adopted approach to best practices, strongly supports Standards-based science curricula, and is accessible to urban and underrepresented student populations.
