Teco: Carbon Monoxide Consumption By Forest And Agroecosystem Soils, Gary M. King
Teco: Carbon Monoxide Consumption By Forest And Agroecosystem Soils, Gary M. King
University of Maine Office of Research Administration: Grant Reports
Carbon monoxide is a more dynamic component of the atmosphere than methane, occurring at a lower concentration but substantially higher flux. CO and hydroxyl radical interact rapidly, affecting a number of atmospheric parameters: the oxidative state of the troposphere; the fate and residence times of methane, non-methane organics and inorganics; tropospheric ozone; and the extent of thermal forcing. Soils consume atmospheric CO, accounting for 10-25% of the global carbon budget, depending on the source estimate. Some of the controls of soil CO uptake and production have been described generally, but much remains unknown. Details of CO uptake in agroecosystems are …
Gasoline Consumption Attributable To Gasoline Powered Watercraft Use In Maine, Jonathan Rubin, Charles Morrris, Suzanne K. Hart
Gasoline Consumption Attributable To Gasoline Powered Watercraft Use In Maine, Jonathan Rubin, Charles Morrris, Suzanne K. Hart
Economic Development
This study was conducted by the Margaret Chase Smith Center for Public Policy (MCSC) of the University of Maine at the request of the Maine Legislature’s Commission to Study Equity in the Distribution of Gas Tax Revenues Attributable to Snowmobiles, All-Terrain Vehicles and Watercraft. The Commission was created by the Legislature with a charge to collect and analyze information to determine an equitable distribution of gas tax revenues used in the enforcement and enhancement of programs supporting off-road vehicle use in Maine. The Commission concluded that snowmobiling, boating and ATV use has increased significantly over recent years and now constitutes …

Acquisition Of Ion Chromatographs And Related Glaciochemistry Equipment, Paul Andrew Mayewski
University of Maine Office of Research Administration: Grant Reports
The goal of this project has been to upgrade the ice core processing and analytical equipment. This has been accomplished in three major areas: the design and construction of an ice core lathe, develpoment of a continuous melting system, and new ion chromatographs. The lathe is a unique ice core processing tool that operates similiar to a wood lathe. The lathe will reduce or eliminate the need for the cores to be hand scraped, the first cleaning step of core preparation.
Our continuous melting system is a modification of existing designs. Unlike other systems, we will collect discrete samples for …

Hierarchical Modeling For Integrated Environmental Assessments, Raymond O'Connor, Deidre Mageean
University of Maine Office of Research Administration: Grant Reports
The distribution of biotic resources over large spatial extents is often a function of climate, of land-use, and of the demographics of the human population but these different classes of independent variables have different spatial scales for their action. One approach to the integration of these effects across scales is to use hierarchical models that incorporate contingencies and constraints in effects. This project seeks to develop such a modeling paradigm by use of classification and regression trees (CART). The hexagonal grid of the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program is used as the spatial grid, with about …
