A Comparative Study Of Cave System Calcium Isotope Ratios: Implications For Quantitative Reconstruction Of Paleorainfall From Speleothems, Cameron B. De Wet, Elizabeth M. Griffith, Andrea Erhardt, Jessica L. Oster

Earth and Environmental Sciences Faculty Publications

Variations in speleothem calcium isotope ratios (δ44Ca) are thought to be uniquely controlled by prior carbonate precipitation (PCP) above a drip site and, when calibrated with modern data, show promise as a semi‐quantitative proxy for paleorainfall. However, few monitoring studies have focused on δ44Ca in modern cave systems. We present a multi‐year comparative study of δ44Ca, carbon isotopes (δ13C), and trace elemental ratios from cave drip waters, modern calcite, and host rocks from two cave systems in California—White Moon Cave (WMC) and Lake Shasta Caverns (LSC). Drip water and calcite δ44Ca from both caves indicate PCP‐ driven enrichment, and we …

Managing Frost Risk, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Frost occurs on clear nights in early spring when the air temperature drops to 2°C or less. Crop damage from frost may occur at any stage of development but is most damaging at or around flowering.

Frost is difficult to manage, and damage will be unavoidable in some seasons. Risk management options proven to reduce frost risk include paddock zoning, crop and variety selection, time of sowing, stubble management and managing inputs. The greatest gains result from in paddock choice/zoning, crop and variety choice, and manipulating the canopy.

How Did The Deer Cross The Road? Reducing Habitat Fragmentation And Wildlife-Vehicle Collision Deaths Through Connective Conservation In The South Mountain Region, Pennsylvania, Jack B. Joiner, Emily R. Kreider, Thomas H. Manning, Madison E. Rowell

Student Publications

While some deleterious effects of road networks and the vehicles that travel them– such as pollution, fossil fuel extraction, and carbon emissions– are widely recognized, their significant role in causing an estimated one million wildlife deaths per day (Shilling et al., 2021) and contributing to habitat loss and degradation, the leading causes of global biodiversity decline (Pinto et al., 2023), has garnered less attention. Connective conservation policies, such as designating wildlife corridors and constructing wildlife crossings on roadways, have been proposed as a means of mitigating these repercussions. This study proposes a connective conservation plan addressing the logistics of a …

Simulating The Compound Impacts Of Climate Change And Sea-Level Rise On Coastal Shallow Groundwater Using An Integrated Surface-Subsurface Hydrologic Model, Zhaoyi Cai

Civil & Environmental Engineering Theses & Dissertations

As climate change intensifies and sea levels rise, coastal aquifers become increasingly vulnerable to interacting oceanic and terrestrial processes. This dissertation examines the combined impacts of climate change and sea-level rise (SLR) on coastal shallow groundwater using an integrated surface-subsurface hydrologic model, focusing on the low-lying Little Creek watershed (LCW) in Norfolk, Virginia. The SWAT-MODFLOW model, a coupled system, unifies land surface, streamflow, and groundwater processes, providing a comprehensive framework for watershed-aquifer analysis. Model parameters were derived from U.S. Geological Survey datasets, relevant literature, station records, and technical reports, followed by meticulous calibration. The validated model first simulated baseline groundwater …

Using Catholic Social Thought And The Normativity Of The Future In Responding To The Super Wicked Problem Of Climate Change, Stephanie Ann Yu Puen

Theology Department Faculty Publications

The climate crisis has been dubbed a “super wicked problem”—one where there is a sense of urgency, complicity in the problem by those who wish to solve it, and difficulty in sacrificing the short term for the long term. To respond to the difficulty of long-term thinking in addressing super wicked problems as part of SDG 13 (Climate Action), there is a need to pay attention to the narratives, norms, and values at work, and how we employ these categories in climate action. This paper discusses how Catholic social thought and the concept of the normativity of the future can …
