Trends in cation, nitrogen, sulfate and hydrogen ion concentrations in precipitation in the United States and Europe from 1978 to 2010: a new look at an old problem

Creator:: Lajtha, Kate and Jones, Julia A.
Abstract:: Industrial emissions of SO₂ and NOₓ, resulting in the formation and deposition of sulfuric and nitric acids, affect the health of both terrestrial and aquatic ecosystems. Since the mid-late 20th century, legislation to control acid rain precursors in both Europe and the US has led to significant declines in both...

Abrupt change in atmospheric CO₂ during the last ice age

Creator:: Ahn, Jinho, Brook, Edward J., Schmittner, Andreas, and Kreutz, Karl
Abstract:: During the last glacial period atmospheric carbon dioxide and temperature in Antarctica varied in a similar fashion on millennial time scales, but previous work indicates that these changes were gradual. In a detailed analysis of one event we now find that approximately half of the CO₂ increase that occurred during...

Disputed Spaces : Concheras, Shrimp Aquaculture, and Conservation in the Mangrove Forests of Southern Esmeraldas, Ecuador

Creator:: Treviño Peña, Melva B.
Abstract:: The mangrove ecosystem has served as a life-support system to large populations of coastal dwellers in Ecuador for many generations. Diverse communities comprised of multi-racial and multi-ethnic groups have formed along the edge of the mangrove forests throughout the Ecuadorian coast. These groups self-identify as being part of an “ancestral”...

Atmospheric CO₂ over the last 1000 years: A high-resolution record from the West Antarctic Ice Sheet (WAIS) Divide ice core

Creator:: Ahn, Jinho, Brook, Edward J., Mitchell, Logan, Rosen, Julia, McConnell, Joseph R., Taylor, Kendrick, Etheridge, David, and Rubino, Mauro
Abstract:: We report a decadally resolved record of atmospheric CO₂ concentration for the last 1000 years, obtained from the West Antarctic Ice Sheet (WAIS) Divide shallow ice core. The most prominent feature of the pre-industrial period is a rapid ∼7 ppm decrease of CO₂ in a span of ∼20–50 years at...

Transdisciplinary Research in Water Sustainability: What’s in it for an Engaged Researcher-Stakeholder Community?

Creator:: Chan, Samuel, Ferguson, Laura, Santelmann, Mary V., and Tilt, Bryan
Abstract:: This study uses semi-structured interviews and an online survey to explore the structure, challenges and outcomes of a five-year National Science Foundation-funded water scarcity modelling project in the Willamette River Basin of Oregon, USA. The research team chose to facilitate broader impacts by engaging stakeholders from the study’s inception (e.g....

Characterizing and Assessing the Researcher-Stakeholder Engagement Process for Water Sustainability : The Willamette Water 2100 Project

Creator:: Ferguson, Laura B.
Abstract:: Natural resource management and policy is ideally informed by the best available science. Natural resource researchers ideally participate in broader impacts activities to extend the reach of their best available research. However, there are many cultural, institutional, and practical barriers to participating in broader impact activities and to incorporating science...

Pacific Coast Groundfish Fishery Assessment and Management: Incorporating Nearshore Surveys into the Fishery Management Framework

Creator:: Haven, Katlyn M. M.
Abstract:: The Pacific coast groundfish fishery is a diverse, important and lucrative commercial and recreational fishery. Part of this fishery’s monitoring process includes regular fishery-independent surveys for stock assessment. Although these fishery-independent surveys are cost-effective, they are susceptible to scientific uncertainty, and they do not currently sample in nearshore (water depth...

Spatio-Temporal Analysis and Modeling in the Marine Environment : Humpback Whale Genetic Variability and Seabird Distributions in the Northeastern Pacific Ocean

Creator:: Dick, Dorothy Marie
Abstract:: The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...

Quantifying Sensitivity and Adaptive Capacity of Shellfish in the Northern California Current Ecosystem to Increasing Prevalence of Ocean Acidification and Hypoxia

Creator:: Gossner, Hannah M.
Abstract:: The severity of carbonate chemistry changes from ocean acidification is predicted to increase greatly in the coming decades, with serious consequences for marine species- especially those reliant on calcium carbonate for structure and function (Fabry et al. 2008). The Northern California Current Ecosystem off the coast of US West Coast...

The Spatial distribution of parks and crime in Seattle, Washington

Creator:: Weems, Candice Michelle
Abstract:: Parks help to build social cohesion within a community. Urban open spaces offer a sense of place, act as the focal points for public gatherings, and provide an opportunity for social networking (Francis, 2003; Hayward, 1989). While offering so much they are also known to be places of disgust and...
