Diffuse Degassing And The Hydrothermal System At Masaya Volcano, Nicaragua, Sophie C. P Pearson
Diffuse Degassing And The Hydrothermal System At Masaya Volcano, Nicaragua, Sophie C. P Pearson
USF Tampa Graduate Theses and Dissertations
Hydrothermal systems change in response to volcanic activity, and in turn may be sensitive indicators of volcanic activity. Fumaroles are a surface manifestation of this interaction. We use time series of soil temperature data and numerical models of the hydrothermal system to investigate volcanic, hydrologic and geologic controls on this diffuse degassing.
Soil temperatures were measured in a low-temperature fumarole field located 3.5 km from the summit of Masaya volcano, Nicaragua. They respond rapidly, on a time scale of minutes, to changes in volcanic activity also manifested at the summit vent. The soil temperature response is repetitive and complex, and …
Analysis Of Mangrove Structure And Latitudinal Relationships On The Gulf Coast Of Peninsular Florida, Peter Novitzky
Analysis Of Mangrove Structure And Latitudinal Relationships On The Gulf Coast Of Peninsular Florida, Peter Novitzky
USF Tampa Graduate Theses and Dissertations
The coastline of Florida has been formed by geomorphic processes which have created suitable habitats for certain vegetation and organisms. One type of vegetation is the mangrove; this plant has a latitudinal range of 24° to 32° N latitude which is associated with local climatic changes (Mitsch 2000). There are three species of mangrove found in Florida: red (Rhizophora), black (Avicennia), and white (Languncularia) (USGS 2006). Mangroves have adapted overtime to live in different ecosystems which cause mangroves, along the Florida coast, of the same species not be the same.
Climatic variation causes individual mangrove trees have structural differences such …
