Policy And Science Of Geothermal Heat Use At Mcmurdo Station, Antarcrtica, Joe Alvine Dec 2010

Policy And Science Of Geothermal Heat Use At Mcmurdo Station, Antarcrtica, Joe Alvine

Department of Environmental Studies: Undergraduate Student Theses

My thesis research project deals with the use of geothermal heat in Antarctica. Currently it is not allowed due to article 7 of the 1991 Protocol on Environmental Protection that placed a 50 moratorium on the exploitation of mineral resources. The US main base in Antarctica, McMurdo Station is currently powered by diesel generators that are inefficient, cause environmental damage, and is expensive to run. By exploring alternative energy options, McMurdo Station can reduce its dependence on non-renewable energy sources. By determining the geothermal potential of McMurdo Station, this project explores the possibilities and benefits that would occur with the …


Does Socio/Economic Status Affect Environmental Awarness In Elementary School Children Interacting With School Gardens?, Grady C. Erickson Dec 2010

Does Socio/Economic Status Affect Environmental Awarness In Elementary School Children Interacting With School Gardens?, Grady C. Erickson

Department of Environmental Studies: Undergraduate Student Theses

This is a case study involving three elementary schools in the greater Lincoln, Nebraska area. These schools were chosen to provide insight to three different economic backgrounds. Saratoga and Randolph from Lincoln Public Schools, and Norris Elementary part of Norris Public Schools 160 was the third school involved in the study. This case study focused on seeing whether socio/economic background had any effect on environmental awareness. To do so, surveys were handed out to each school to help measure environmental awareness. These surveys also helped determine where the environmental literacy standards were in the elementary schools of Lincoln, Nebraska. The …

The Influence Of Sediment Bays On Reducing Incoming Sediment In Holmes Lake: Lincoln, Nebraska, Alex Fischer Dec 2010

The Influence Of Sediment Bays On Reducing Incoming Sediment In Holmes Lake: Lincoln, Nebraska, Alex Fischer

Department of Environmental Studies: Undergraduate Student Theses

Lakes in the urban environment are often challenged with issues of water quality. Holmes Lake, located in Lincoln, Nebraska, has experienced such problems. In an effort to improve water quality in Holmes Lake, the city installed several control devices. One of the devices installed were sediment bays. This study evaluated the effectiveness of those sediment bays by measuring turbidity and suspended sediment after rain events at different locations in and out of the bays. The study found that the bays helped to reduce sediment in some cases, but in other cases no reduction was shown.


Educators' Attitudes Toward Outdoor Classrooms And The Cognitive Benefits In Children, Carlie Speedlin Dec 2010

Educators' Attitudes Toward Outdoor Classrooms And The Cognitive Benefits In Children, Carlie Speedlin

Department of Environmental Studies: Undergraduate Student Theses

A case study was organized at a K-5 elementary school in Lincoln, Nebraksa. This school is Saratoga Elementary School and is a United States Title I Distinguished School1 under No Child Left Behind. It has a population of 266 students, with 47% being minority, 1% gifted, and 28% special education (LPS School Profile Brochure). 80% of the student population is eligible for free/reduced meals, implying that it’s a school with a lower socioeconomic status. At this school a garden space was constructed and an after school garden club was implemented for this case study. The club had been running since …


Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone Dec 2010

Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone

Department of Environmental Studies: Undergraduate Student Theses

The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …
