Testing the ArcGIS Marine Data Model : busing spatial information to examine habitat utilization patterns of reef fish along the west coast of Hawaii

Aaby, Alyssa Anne 06 March 2007 (has links)
In response to anthropogenic pressures that have degraded habitat and put marine resources at risk (Leslie et al., 2003; Mumby et al., 2001; Puniwai et al., 2003), there has been a growing interest in the use of marine protected areas (MPAs) as a management tool to help slow, prevent or reverse negative anthropogenic changes. Recent studies have shown that the most effective MPAs are those which represent a full range of habitat types (Leslie et al., 2003; Carr et al., 2003). Yet, available scientific research has not evaluated the near-shore marine habitat utilization along the West Coast of Hawaii at the large-scales utilized by resource managers. Thus, this study focused on identifying the regional habitat utilization patterns for selected Hawaiian reef fish species to determine the most effective combination of habitat types. In addition, the habitat utilization analysis was used as one of several case studies to test the ArcGIS Marine Data Model���s (MDM) (Wright et al., 2001) adaptability to work with real-world data and perform real-world analyses, as well as meet the five goals outlined by the MDM Working Group (Wright et al., 2001). Created in 2001, by researchers from Oregon State University, Duke University, NOAA, the Danish Hydrologic Institute and ESRI, the MDM is a geodatabase template tailored to meet the needs of the marine GIS user community. Ultimately, this analysis will aid marine managers as it establishes correlations between small and large-scale habitat information, which provides a regional look at habitat utilization. Also, by testing the functionality of the MDM, its strengths and weaknesses will be identified so that it can be improved to better serve the marine GIS user community. / Presentation date: 2004-06-08 / Graduation date: 2005

To Fish as Formerly: A Resurgent Journey back to the Saanich Reef Net Fishery

Claxton, Nicholas Xemtoltw 31 August 2015 (has links)
According to W̱SÁNEĆ oral history, the W̱SÁNEĆ people have lived on their territorial homelands back to the time of creation. The W̱SÁNEĆ way of life has been passed on to each succeeding generation through an educational way, centered in large part on the W̱SÁNEĆ Reef Net Fishery. This fishing practice formed the backbone of W̱SÁNEĆ culture and society. Despite being protected by the Douglas Treaty of 1852, over the next 163 years of colonization, the knowledge, ceremony, practice, and educational way of the SX̱OLE (Reef Net) was nearly lost. Using a framework for Indigenous Resurgence, this dissertātiō or path focuses on the revitalization and restoration of the SX̱OLE. This resurgent path described herein tells the story of how the “researcher” pulled together the disappearing knowledge of the SX̱OLE, reinvigorated cross border cooperation between the W̱SÁNEĆ and their Xwelemi relatives, and how after being named ȻWENÁLYEN, or the Reef Net Captain through ceremony was able to coordinate the community based creation and fishing of the first SX̱OLE on Canadian waters in 100 years. This resurgent path is just the beginning of a long and endless journey forward by looking backward, where the W̱SÁNEĆ people can be a proud people of the SX̱OLE once again. / Graduate

The effects of decling environmental pH on coral microstructure and morphology

Tibbits, Matthew A 01 December 2009 (has links)
Coral reefs are faced and will be faced with many challenges this century. One danger is the rapid decline of oceanic pH due to anthropogenic sources. The more acidic the environment becomes, the harder reefs and coral (order: scleractinia) in particular will be hit. Experiments to measure the effect on scleractinian coral were performed to glean a better understanding of the processes that will be affected by our acidifying oceans. Additionally, the search for and analysis of coral microstructure and micromorpholgy were carried out in an attempt to understand homology within an environmentally responsive taxa.

Capitol Reef: the Forgotten National Park

Thow, Jonathan Scott 01 May 1986 (has links)
The purpose of this study was to examine the changing relationship between the National Park Service and the residents of Wayne County, Utah. In 1937, Capitol Reef National Park was created as a result of the efforts made by local residents looking for a solution to their economic problems. Over the next five decades, the anticipated economic upturn spurred by the National Park did not develop. Instead, the relationship between the parties involved underwent a radical change because of conflicts over private landholdings, grazing and mineral rights, expansion, development, and road building. While this study does trace the growth of Capitol Reef into a national park, it is not an administrative history of the site. Its focus is on failure of the Park to live up to the expectations of its early supporters and the resulting deterioration of the relationship between local residents and the National Park Service.
