Michelle A Nott
Biography
Michelle Nott (formerly Lutz) is a Physical Scientist at the USGS Wisconsin Water Science Center. She started at the Center in 2001, and has worked on various projects since then. For several years she worked intensively with the NAWQA Mercury Topical Team, investigating biogeochemical cycling of mercury through geographically diverse ecosystems. Her emphasis was on streambed sediment and consideration of the distribution and prevalence of various bed sediment characteristics on interpretation of analytical results. Following the completion of this project, she turned her attention to more local studies. Her recent work has focused on investigations in urban streams with chronically depressed dissolved oxygen levels, as well as investigations of biofilm communities growing in streams receiving airport deicer runoff. In addition to these more focused studies, she also provides field, GIS, and database support to other local and regional projects.

Science and Products
Biological water-quality assessment of selected streams in the Milwaukee Metropolitan Sewerage District Planning Area of Wisconsin, 2007
Changes in the water quality of stream ecosystems in an urban area may manifest in conspicuous ways, such as in murky or smelly streamwater, or in less conspicuous ways, such as fewer native or pollution-sensitive organisms. In 2004, and again in 2007, the U.S. Geological Survey sampled stream organisms—algae, invertebrates, and fish—in 14...

Evaluation of aquatic biota in relation to environmental characteristics measured at multiple scales in agricultural streams of the Midwest, 1993-2004
This study evaluated the relations between algal, invertebrate, and fish assemblages and physical environmental characteristics of streams at the reach, segment, and watershed scale in agricultural settings in the Midwest. The 86 stream sites selected for study were in predominantly agricultural watersheds sampled as part of the U.S. Geological...

Data on mercury in water, bed sediment, and fish from streams across the United States, 1998-2005
The U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) and Toxic Substances Hydrology Programs conducted the National Mercury Pilot Study in 1998 to examine relations of mercury (Hg) in water, bed sediment and fish in streams across the United States, including Alaska and Hawaii. Water and bed-sediment samples were analyzed...

Mercury cycling in stream ecosystems. 2. Benthic methylmercury production and bed sediment - Pore water partitioning
Mercury speciation, controls on methylmercury (MeHg) production, and bed sediment−pore water partitioning of total Hg (THg) and MeHg were examined in bed sediment from eight geochemically diverse streams where atmospheric deposition was the predominant Hg input. Across all streams, sediment THg concentrations were best described as a combined...

Environmental Settings of Selected Streams Sampled for Mercury in Oregon, Wisconsin, and Florida, 2002-06
From 2002 through 2006, the U.S. Geological Survey National Water-Quality Assessment Program conducted studies investigating mercury biogeochemistry and food-web bioaccumulation in eight streams from three distinct geographic areas of the United States. These streams varied greatly in environmental characteristics, including land-cover, hydrologic...
Bell, Amanda H.; Lutz, Michelle A. Procedures for collecting and processing streambed sediment and pore water for analysis of mercury as part of the National Water-Quality Assessment Program
Mercury (Hg) contamination is an issue of national concern, affecting both wildlife and human health. The U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program, in association with the USGS Toxic Substances Hydrology Program and the USGS National Research Program, has initiated two levels of studies to investigate Hg...
Lutz, Michelle A.; Brigham, Mark E.; Marvin-DiPasquale, Mark Total mercury, methylmercury, methylmercury production potential, and ancillary streambed-sediment and pore-water data for selected streams in Oregon, Wisconsin, and Florida, 2003-04
Mercury contamination of aquatic ecosystems is an issue of national concern, affecting both wildlife and human health. Detailed information on mercury cycling and food-web bioaccumulation in stream settings and the factors that control these processes is currently limited. In response, the U.S. Geological Survey (USGS) National Water-Quality...

Water-Quality Characteristics for Selected Sites Within the Milwaukee Metropolitan Sewerage District Planning Area, Wisconsin, February 2004-September 2005
The Milwaukee Metropolitan Sewerage District (MMSD) Corridor Study is a three-phase project designed to improve the understanding of water resources in the MMSD planning area to assist managers and policy makers in their decisions. Phase I of the Study involved the compilation of existing data from multiple agencies into a single database. These...

Water-resources-related information for the Milwaukee Metropolitan Sewerage District planning area, Wisconsin, 1970-2002
The Milwaukee Metropolitan Sewerage District (MMSD) Corridor Study is a three-phase project designed to improve the understanding of water resources in the stream corridors of the MMSD planning area by initially compiling existing data and using the compiled information to develop 3-year baseline and long-term monitoring plans. This report is one...
