Tectonic Influences On The Preservation Of Marine Terraces: Old And New Evidence From Santa Catalina Island, California, R. Randall Schumann, Scott A. Minor, Daniel R. Muhs, Lindsey T. Groves, John P. Mcgeehan
Tectonic Influences On The Preservation Of Marine Terraces: Old And New Evidence From Santa Catalina Island, California, R. Randall Schumann, Scott A. Minor, Daniel R. Muhs, Lindsey T. Groves, John P. Mcgeehan

The California Channel Islands contain some of the best geologic records of past climate and sea-level changes, recorded in uplifted, fossil-bearing marine terrace deposits. Among the eight California Channel Islands and the nearby Palos Verdes Hills, only Santa Catalina Island does not exhibit prominent emergent marine terraces, though the same terrace-forming processes that acted on the other Channel Islands must also have occurred on Santa Catalina. We re-evaluated previous researchers' field evidence and examined new topographic, bathymetric, and stream-profile data in order to find possible explanations for the lack of obvious marine terrace landforms or deposits on the island today. …

Dr. Robert P. Alexander graduated from Marshall University in 1959. After graduating, Dr. Alexander was hired by Marshall University and traveled to the eastern panhandle of West Virginia to recruit prospective students. It was here he became interested in the town of Cass, WV. In 1969, Dr. Alexander completed his doctorate and became a professor of management and marketing. Dr. Alexander was also the Dean of Marshall University’s College of Business and also served sixteen years on Huntington, WV’s city council. In 1975 Dr. Alexander returned to Cass and created a living history of both the town and timbering industry …
Assessment Of Diver Impact During The Spiny Lobster Sport Season, Florida Keys, Usa, Mark Lewis Hartman
Assessment Of Diver Impact During The Spiny Lobster Sport Season, Florida Keys, Usa, Mark Lewis Hartman
USF Tampa Graduate Theses and Dissertations
The Spiny Lobster (Panulirus argus) fishery in Florida is closed during the spawning season (March-July) except for a two-day recreational `miniseason' for sport divers in July, several days prior to the opening of the commercial fishing season. In Monroe County, recreational fishers, who possess a valid Saltwater Fishing License with crawfish stamp, are allowed to harvest six lobsters per day, each with a minimum carapace length of 76.2 mm (3.0 inches). During these two days, approximately 50,000 people attempt to catch lobster, and the number of boats visiting the reef has been estimated to be up to 900 times higher …
Sustainable Livelihood Analysis Of An Irrigation Project In Ta Haen, Cambodia., Irene Rehberger Bescos
Sustainable Livelihood Analysis Of An Irrigation Project In Ta Haen, Cambodia., Irene Rehberger Bescos
USF Tampa Graduate Theses and Dissertations
This study examines potential livelihood outcomes from a recently established irrigation project in Ta Haen, Cambodia, in a sustainable livelihoods framework. The aim of this SAUCE irrigation project is to provide water for drinking and irrigation purposes with the goal of enhancing food by producing an extra rice harvest, the staple, per year. Field research conducted in December 2011 provided qualitative data from questionnaires, key informant interviews, and participant and direct observation, in addition to quantitative data from water quality analysis focusing on arsenic (a potential risk), pH, EC and temperature. Most of the people in the village did not …
Fire Suppression And Burnt Sediments: Effects On The Water Chemistry Of Fire-Affected Wetlands, David Blake, Hoa Lu, Pierre Horwitz, Mary Boyce
Fire Suppression And Burnt Sediments: Effects On The Water Chemistry Of Fire-Affected Wetlands, David Blake, Hoa Lu, Pierre Horwitz, Mary Boyce
Research outputs 2012
Preventing fire from entering wetland areas during seasonal or prolonged drought, or suppressing fire once it has entered a wetland, requires consideration of the consequences of the fire-management action on water quality. Two approaches can be taken to suppress such fires: chemical fire retardants or the flooding of sediments. We determine a lack of information relating to the effects of these approaches for water quality within fire-affected wetlands. The aim of this study was to gain a preliminary understanding of the effects of three treatments: two chemical treatments and saturation. Microcosms were established to test sediments from a wetland on …
Sustainability Education As A Framework For Enhancing Environmental Stewardship In Young Leaders: An Intervention At Tryon Creek Nature Day Camp, Andrea Nicole Lawrence
Sustainability Education As A Framework For Enhancing Environmental Stewardship In Young Leaders: An Intervention At Tryon Creek Nature Day Camp, Andrea Nicole Lawrence
Dissertations and Theses
UNESCO established Sustainability Education as a top priority when it declared 2005 - 2014 to be the global decade for sustainability. Sustainability education can be implemented in outdoor programs such as nature summer camps in order to build environmental stewardship and ecological literacy in counselors and campers. This study sought to determine the extent to which an ecology and leadership training given to assistant counselors at Tryon Creek State Natural Area day camp achieved the goals of sustainability education--for the assistant counselors to learn about ecology, develop stewardship attitudes and behaviors toward the environment, and become positive role models for …
