A High-Resolution Paleoenvironmental And Paleoclimatic History Of Extreme Events On The Laminated Sediment Record From Basin Pond, Fayette, Maine, U.S.A., Daniel R. Miller
Masters Theses
Future impacts from climate change can be better understood by placing modern climate trends into perspective through extension of the short instrumental records of climate variability. This is especially true for extreme climatic events, such as extreme precipitation and wildfires, as the period of instrumental records provides only a few examples and these have likely have been influenced by anthropogenic warming. Multi-parameter records showing the past range of climate variability can be obtained from lakes. Lakes are particularly good recorders of climate variability because sediment from the surrounding environment accumulates in lakes, making them sensitive recorders of climate variability and …
Assessing Kiln-Produced Hardwood Biochar For Improving Soil Health In A Temperate Climate Agricultural Soil, Emily J. Cole
Assessing Kiln-Produced Hardwood Biochar For Improving Soil Health In A Temperate Climate Agricultural Soil, Emily J. Cole
Doctoral Dissertations
Soil quality has become a major factor used in assessing sustainable land management and the overall environmental quality, food security, and economic viability of agricultural lands. Recently, biochar has been touted as having many potential uses as a soil amendment for improving soil quality, specifically improving cation exchange capacity, pH and nutrient availability. However, soil biology also plays a significant role in biogeochemical processes that influence soil health and should be included in a more comprehensive study of soil health. This dissertation describes 4 projects within the same 3-year field study with the cumulative purpose of better understanding the effect …

The Benefits of a Manure-based Biochar: Mike McGolden
Biochar has been in existence for thousands of years. However, it has only been in the past decade that there has been a resurgence in the thirst for knowledge about biochar and research into how it is made and its impact on the environment.
This resurgence has brought about a tremendous amount of research and a rapid growth in education among the general population about biochar – especially in the past …

Rescuing biochar: Pre - application techniques to enhance plant responses to biochar additions: Nigel Gale, U of Toronto
A growing body of literature indicates variable responses of different plant species to biochar, including positive, neutral, and negative, suggesting that it is important to investigate the nature and mechanism of species-specific responses to biochar additions. Neutral or negative plant responses to additions of biochars have commonly been reported in prior studies, and are likely the result of a combination of changes in soil properties (e.g. pH, surface area, and nutrient and water retention) and the production of volatile organic compounds from …

Cascading Uses of Biochar - Hans-Peter Schmidt, Ithaka Institute
In addition to the use of biochar as a soil amendment, there are an increasing number of ways to incorporate biochar into different eco- and industrial systems. Thus feeding biochar to livestock has numerous benefits not only for the animals, but it also helps reduce greenhouse gas emissions and improves nutrient retention in animal manure. The use of biochar in building materials is just beginning to be studied but shows promise in the ability to insulate, decontaminate air, provide odor and humidity control. Biochar as pillow filling to induce perfectly reposing …

USBI Biochar Conferences
Biochar and the Sustainability Imperative. Now marks a critical time: as biochar comes of age and markets begin to develop, this young industry is attracting naysayers, doubters and get-rich-quick-schemers. Ethical biochar production and use is of paramount importance as we continue to lay the groundwork for biochar as a model for carbon neutral/negative business, landscape restoration and truly green technology. Shortcuts, poor quality product and unsustainable use of biomass could bring biochar to its knees before it gains the traction necessary to fulfill its promises. This discussion will explore opportunities and pitfalls in feedstocks sustainability, production integrity and ethics in …

Sorptive Treatment of Metals and Nitro Explosives in Water Using Biochar -
Seok-Young Oh1*,
Biochar, a solid byproduct of a pyrolysis process was investigated as a sorbent to remove toxic metals and nitro explosives from natural water and wastewater. It was hypothesized that biochar can sorb dissolved metals and nitro explosives due to its high surface area and strong sorption affinity of aromatic organic compounds. Using a tube furnace under N2, various types biochar were synthesized by changing biomass (poultry litter, sludge, fallen leaves, corn stalk, rice straw, and coffee grounds) and temperature (250, 400, …

Ecohydrologic Impacts Of Climate And Land Use Changes On Watershed Systems: A Multi-Scale Assessment For Policy, Paul A. Ekness
Open Access Dissertations
Maintaining flows and quality of water resources is critical to support ecosystem services and consumptive needs. Understanding impacts of changes in climate and land use on ecohydrologic processes in a watershed is vital to sustaining water resources for multiple uses. This study completes a continental and regional scale assessment using statistical and simulation modeling to investigate ecohydrologic impacts within watershed systems.
Watersheds across the continental United States have diverse hydrogeomorphic characters, mean temperatures, soil moistures, precipitation and evaporation patterns that influence runoff processes. Changes in climate affect runoff by impacting available soil moisture, evaporation, precipitation and vegetative patterns. A one …

Uncertainty In Climatic Change Impacts On Multiscale Watershed Systems, Olga V. Tsvetkova
Open Access Dissertations
Uncertainty in climate change plays a major role in watershed systems. The increase in variability and intensity in temperature and precipitation affects hydrologic cycle in spatial and temporal dimensions. Predicting uncertainty in climate change impacts on watershed systems can help to understand future climate-induced risk on watershed systems and is essential for designing policies for mitigation and adaptation. Modeling the temporal patterns of uncertainties is assessed in the New England region for temperature and precipitation patterns over a long term. The regional uncertainty is modeled using Python scripting and GIS to analyze spatial patterns of climate change uncertainties over space …
A High-Resolution Temperature Record From Lakes Of The Lofoten Islands, Northwestern Norway Based On A New Uk37 Temperature Calibration From In Situ Measurements, Xiaohui Huang
Masters Theses 1911 - February 2014
Water filters and sediment trap samples were collected weekly from late May to early September 2009 from four lakes of the Lofoten archipelago, northwestern Norway, and were used to explore the applicability of the alkenone unsaturation index (UK37) for temperature reconstruction in limnic systems in the area. For the first time, we observed the occurrence of long-chain alkenones (LCAs) within the water columns of lakes in this region. Water filters from two of the four studied lakes contained measurable concentrations of alkenones that were restricted to spring turnover and disappeared with the onset of summer stratification. These results indicate that …
