Keeping Pace With Relative Sea Level Rise: Marsh Platform Monitoring Shows Minimal Sediment Deficit Along The Louisiana Coast, Kelly Marie Sanks Dec 2018

Keeping Pace With Relative Sea Level Rise: Marsh Platform Monitoring Shows Minimal Sediment Deficit Along The Louisiana Coast, Kelly Marie Sanks

Graduate Theses and Dissertations

Recent reports estimate that the marshes of the Mississippi Delta receive just 30% of the sediment necessary to sustain current land area1. An extensive monitoring campaign by the USGS and LCPRA provides direct measurements of sediment accumulation, subsidence rates, and deposit characteristics along the coast over the past 10 years2, allowing us to directly evaluate this sediment balance. By interpolating bulk density, organic fraction, and vertical accretion rates from 273 sites, a direct measurement of organic and inorganic sediment accumulation can be made. Results show that a total of 82 MT/year of sediment is delivered to the coast. Using a …


Sustainable Intensification Of Agriculture: Opportunities And Challenges For Food Security And Agrarian Adaptation To Environmental Change In Bangladesh, Aaron Michael Shew May 2018

Sustainable Intensification Of Agriculture: Opportunities And Challenges For Food Security And Agrarian Adaptation To Environmental Change In Bangladesh, Aaron Michael Shew

Graduate Theses and Dissertations

This dissertation investigates three unique aspects of sustainable agricultural intensification (SAI) in the context of Bangladeshi rice production. The first article presents a qualitative analysis of SAI and farmer surveys in the embanked polder region of coastal Bangladesh. The second article investigates the global food security and environmental impacts of already adopted High Yielding Variety (HYV) rice and double-cropped rice systems in Bangladesh using a spatial partial equilibrium trade model and a Life Cycle Assessment (LCA). The final article demonstrates a remote sensing methodology for monitoring dry season rice production at 30 m resolution in Bangladesh using a harmonic time …

A Naturalist’S Guide To The Great Plains, Paul A. Johnsgard

Zea E-Books Collection

This book documents nearly 500 US and Canadian locations where wildlife refuges, nature preserves, and similar properties protect natural sites that lie within the North American Great Plains, from Canada’s Prairie Provinces to the Texas-Mexico border. Information on site location, size, biological diversity, and the presence of especially rare or interesting flora and fauna are mentioned, as well as driving directions, mailing addresses, and phone numbers or internet addresses, as available. US federal sites include 11 national grasslands, 13 national parks, 16 national monuments, and more than 70 national wildlife refuges. State properties include nearly 100 state parks and wildlife …


President Trump Tweets Supreme Leader Kim Jong-Un On Nuclear Weapons: A Comparison With Climate Change, David E. Allen, Michael Mcaleer Jan 2018

President Trump Tweets Supreme Leader Kim Jong-Un On Nuclear Weapons: A Comparison With Climate Change, David E. Allen, Michael Mcaleer

Research outputs 2014 to 2021

A set of 125 tweets about North Korea's Supreme Leader Kim Jong-Un by President Trump from 2013 to 2018 are analysed by means of the data mining technique, sentiment analysis. The intention is to explore the contents and sentiments of the messages contained, the degree to which they differ, and their implications about President Trump's understanding and approach to international diplomacy. The results suggest a predominantly positive emotion in relation to tweets about North Korea, despite the use of questionable nicknames such as "Little Rocket Man". A comparison is made between the tweets on North Korea and climate change, madefrom …
