High-Resolution Investigation Of Event Driven Sedimentation: Response And Evolution Of The Deepwater Horizon Blowout In The Sedimentary System, Rebekka A. Larson

USF Tampa Graduate Theses and Dissertations

This Dissertation combines the investigation of the sedimentological impacts of the Deepwater Horizon (DwH) blowout event in the deep-sea benthos, with the refinement and advancement of methods and approaches for high-resolution investigations of events preserved in sedimentary records. An approach that combined, rapid collection of cores, a continued annual time series collection of cores, and high-resolution sampling and analyses, in particular short-lived Radioisotopes (SLRad), enabled the temporal resolution required to detect the sedimentary response to the short-duration DwH event, and evaluate post-event sedimentation patterns at a comparable time scale (months).

The collection of 179 sediment cores from 80 sites between …

Sedimentology And Biostratigraphy Of The Early-Middle Miocene Transition In Nw Transylvanian Basin (Pâglişa And Dej Sections), Claudia Beldean, Răzvan Bercea, Sorin Filipescu

Studia UBB Geologia

The Early - Middle Miocene transition can be studied in several sections from the north-western Transylvanian Basin, across the boundary between the Hida and Dej Formations. The Pâglişa and Râpa Dracului (Dej locally outcrop) sections offer a very good record of the changes in the sedimentary facies and micropaleontological content across the boundary. The lower parts of the sections display the upper Hida Formation with prodelta fine grained sediments covered by coarser grained sediments related to a delta front progradation. Four sedimentary facies associations have been separated based on grain size and associated sedimentary structures. Micropaleontological assemblages are moderately to …

Clastic Sediments In Caves - Imperfect Recorders Of Processes In Karst, Ira D. Sasowsky

KIP Articles

Clastic sediments have played an important role in deciphering geologic history and processes since the inception of the discipline. Early studies of caves applied stratigraphic principles to karst deposits. The majority of cave deposits are breakdown and alluvium. The alluvial materials have been successfully investigated to determine ages of caves, landscape evolution, paleoenvironmental conditions, and paleobiota. Rapid stage changes and the possibility of pipe-full flow make cave deposits different than surface deposits. This and other factors present difficulties with interpreting the cave record, but extended preservation is afforded by the “roofing” of deposits. Dating by magnetism or isotopes has been …

Morphodynamics Of Bunces Pass, Florida, Jack C. Wilhoit Ii

USF Tampa Graduate Theses and Dissertations

Bunces Pass is an unstructured tide-dominated inlet just north of the main entrance to Tampa Bay, Florida. The inlet has been stable for at least 130 years, as the size, shape, and orientation have remained unchanged. The morphological evolution of the Bunces Pass ebb-tidal delta is influenced by adjacent inlets. Historically, the ebb tidal delta was extremely large, due to the presence of the south channel of Pass-A-Grille Pass. As the tidal prism decreased through the south channel, the sheltering effect produced by the large ebb tidal delta diminished, and large volumes of sand began migrating shoreward. Sediment from the …

Radiochemistry And Sedimentology Of Surficial Mud-Dominated Deposits, Hillborough Bay, Florida, Gregg R. Brooks, Hepsi D. Zsoldos, Robert H. Byrne, Larry J. Doyle

Reports

Hillsborough Bay is the northeast lobe of Tampa Bay, the largest open water estuary on Florida's west coast. For a complete description of the setting and previous works, the reader is referred to Doyle, et al. (1989). The Phase I study of fine-grained sediments in Hillsborough Bay (Brooks and Doyle, 1989) established distribution patterns and average accumulation rates of mud-dominated sediments at selected sites within the Bay over the past several thousand years. Phase II of the study, the focus of this investigation concentrates on the uppermost 50-100 cm. of the sediment column, or those sediments believed to have been …
