Non Technical Summary
This project provides a collaborative framework for participating scientists from State Agricultural Experiment Stations (SAES); universities; federal, state, local, and tribal government agencies; national forests and laboratories; environmental institutes; private companies; and other research organizations to cooperate in sponsoring the National Atmospheric Deposition Program (NADP). The NADP is a network of sites and cooperators that measure the chemistry of precipitation on a weekly basis. The NADP provides the only regional and national-scale data and information on the amounts, geographic distribution, and trends in the chemistry of precipitation in the United States. These data, which have been collected since the late 1970s on some sites, provide important information to scientists and policymakers on the background levels of atmospheric deposition and its effects on ecosystems, climate change, and human health.

Goals / Objectives
The NADP has had three objectives during its existence: 1.to characterize geographic patterns and temporal trends in chemical or biological atmospheric (wet and dry) deposition 2.to support research activities related to: (a) the productivity of managed and natural ecosystems (b) the chemistry of surface and ground waters, including estuaries (c) critical loads in terrestrial and aquatic ecosystems (d) the health and safety of the nations food supply and (e) source-receptor relationships and 3.to support education and outreach through the development of informational materials and programs aimed at people of all ages. To achieve these objectives, NADP provides timely deliverables free of charge. Scientists, educators, students, policy-makers, and others are encouraged to access data from the NADP website (http://nadp.isws.illinois.edu/). This site offers on-line retrieval of individual data points, seasonal and annual averages, trend plots, concentration and deposition maps, reports, manuals, educational brochures, and other information about NRSP-3. Quality-assured data and information from all networks are loaded quarterly into the on-line database system with a lag of ~180 days. Information available from this website and linked database management system constitute the deliverables that support the project objectives. NADP also addresses special request data products, answers scientific questions, and assists users to find related information. Complementing the on-line data and information are publications such as annual data summaries, annual meeting proceedings and presentations, quality assurance documents (e.g., quality management plans), manuals, informational and educational brochures, and reports. All publications are available online (nadp.isws.illinois.edu/lib/). Project Assessment and Revision of Objectives: In order to assess the type and amount of research activity supported by NRSP-3, participants are asked to report their program activities and publications that use NADP data annually. Additionally information is obtained from online literature repositories to locate all publications that reference or use NADP data, maps, and other information. These are summarized annual and provided on the NADP website ( http://nadp.isws.illinois.edu/lib/bibliography.aspx). More than ~95% of these publications are peer-reviewed journal articles and reports, including theses and dissertations. The balance includes informational pieces, such as newspaper articles and other news reports. Over the last three complete years (2010-2012), publications listed have numbered 146, 172, and 170 publications, respectively. This demonstrates that NRSP-3 is achieving the primary function of NRSPs, namely to support research (and NADPs Objective #2). Objective (1) was changed during the 2002-06 funding period to chemical or biological atmospheric (wet and dry) deposition. This objective now explicitly mentions wet and dry deposition, including the (biological) deposition of plant pathogens, such as ASR spores. Current networks to measure air concentrations of ammonia and mercury make possible the estimation of dry deposition fluxes, building new research support capacity. Research activities under objective (2) were amended to address emerging interest in critical loads and the health and safety of the nations food supply. Including the health of food supplies embraces the work being done to understand mercury sources that have led to advisories in 49 states to limit fish consumption, and also embraces the work being done to track SBR, a disease that can drastically reduce yields in unprotected soybean crops. Objective (3) articulates what is already being done (see summary in Integration and Documentation of Research Support). These points show that the NRSP-3 is adjusting to our current understanding and adapting to new needs (e.g., ambient ammonia monitoring, ASR pathogen transport, radioactive fallout from Fukushima, and related studies.).

Project Methods
On a weekly basis, samples from all NADP / NTN sites are mailed to the Central Analytical Lab at the University of Illinois for analysis.Samples are analyzed for nitrate, ammonium, base cations (calcium, magnesium, and potassium), sulfate, phosphate, sodium, and chloride. Samples also are measured for conductivity and pH.Data are compiled and posted on the NADP websitehttp://nadp.sws.uiuc.edu/

Progress 01/21/15 to 09/30/19

Outputs
Target Audience:This project represents a contribution of data to a national database on the chemistry of precipitation. Target audience includes other scientists who use the data for publications coming from the data set, policymakers who use the data to set benchmarks for emissions, land managers who are establishing critical loads of deposition to ecosystems, and other users (educators, students) who use the freely accessible data. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Undergraduate and graduate students are involved in this project and have learned valuable forestry skills, including tree identification and size measurements, tree seedling identification, soil resource sampling and analysis, and data analysis and modeling. During the reporting period, undergraduate and graduate students, a postdoc, and a technician were involved. How have the results been disseminated to communities of interest?As part of the national network, results have been disseminated via the website and publications. http://nadp.slh.wisc.edu/ What do you plan to do during the next reporting period to accomplish the goals?We will continue weekly sampling and shipping of samples to the University of Wisconsin for analysis. We also will continue observational and manipulative experiments designed to test effects of atmospheric deposition on the species composition and productivity of forest ecosystems.

Impacts
What was accomplished under these goals? This project is Michigan's contribution to a cooperative effort among State Agricultural Experiment Stations (and other agencies) to monitor the amount, geographic distribution, and temporal trends in precipitation try and wet chemical deposition. The contributed data from the KBS NADP site and all NADP sites is available at: http://nadp.slh.wisc.edu/ under NTN (National Trends Network) . Weekly samples of wet deposition at Kellogg Biological Station were collected throughout 2016 by Kellogg Forest personnel and shipped to the University of Illinois for analysis. In addition to the weekly sampling, we are conducting experiments to understand the effects of atmospheric deposition on productivity and tree species composition of forests. We are using two approaches to understand effects of changes in element availability due to atmospheric deposition: 1) experimental fertilizations of targeted trees of four important species and 2) monitoring the dynamics of mature tree and seedling dynamics across a natural soil fertility gradient in northern Michigan. The overall project (NRSP-3) has supported numerous publications and is the only national scale database to monitor the amounts of pollutants that are being deposited on ecosystems. These accomplishments are reported by the NADP office (http://nadp.slh.wisc.edu/lib/).
