Evaluation Of Geophysical And Thermal Methods For Detecting Submarine Groundwater Discharge (Sgd) In The Suwannee River Estuary, Florida, Matthew Weiss
USF Tampa Graduate Theses and Dissertations
Submarine groundwater discharge (SGD) represents a significant portion of the total discharge from coastal aquifers through diffuse seepage and point source springs, but can be difficult to locate. SGD is important as it can be a source of nutrients to estuaries and other coastal ecosystems. In an effort to evaluate geophysical and thermal methods for detecting SGD on the Florida Gulf coast, a suite of water-borne surveys were run in conjunction with aerial thermal imagery over the lower Suwannee River and estuary in March and September 2005. Thermal imagery exploits temperature differences between discharging groundwater and surface water. Thermal images …
Taphonomic And Sedimentologic Study Of The Cretaceous Tepee Buttes Limestone, Hilary G. Close
Taphonomic And Sedimentologic Study Of The Cretaceous Tepee Buttes Limestone, Hilary G. Close
Honors Papers
The Tepee Buttes methane seep deposits exist today as topographically defined limestone features in the surrounding Pierre Shale of the Campanian Western Interior Seaway. The present sloping surface has previously been assumed to be indicative of original seep structure, and biofacies were interpreted as roughly ringing a central vent core. Contradictory field observations in this study have prompted a more detailed taphonomic approach to the Tepee Buttes limestone, and certain depositional features such as reworked horizontal shell beds were noted and examined in detail for the first time. The results of a taphonomic and sedimentologic analysis reveal a complex history …
