Using Remote Sensing And Machine Learning To Locate Groundwater Discharge To Salmon-Bearing Streams, Mary E. Gerlach, Kai C. Rains, Edgar J. Guerrón-Orejuela, William J. Kleindl, Joni Downs, Shawn M. Landry, Mark C. Rains

School of Geosciences Faculty and Staff Publications

We hypothesized topographic features alone could be used to locate groundwater discharge, but only where diagnostic topographic signatures could first be identified through the use of limited field observations and geologic data. We built a geodatabase from geologic and topographic data, with the geologic data only covering ~40% of the study area and topographic data derived from airborne LiDAR covering the entire study area. We identified two types of groundwater discharge: shallow hillslope groundwater discharge, commonly manifested as diffuse seeps, and aquifer-outcrop groundwater discharge, commonly manifested as springs. We developed multistep manual procedures that allowed us to accurately predict the …

Impacts Of Experiential Learning On The Affective Domain: Gaining Insight Into How To Broaden Participation In The Geosciences, Meghan Lindsey Cook

USF Tampa Graduate Theses and Dissertations

Experiential learning exercises, such as field trips, are a common pedagogical practice in geoscience curriculums. Their purpose is to facilitate the transfer of knowledge gained in a classroom or lab setting into a field setting, but can be considered a barrier for entry into the geosciences for those with disabilities, caregiver/employment responsibilities, or financial constraints. Educators have begun turned to other modalities, such as virtual field experiences (VFEs), to create a more inclusive environment in the geosciences. However, the validity of VFEs as a replacement for, or augmentation to traditional field trips has yet to be established. The cognitive domain …

Caveats To Exogenous Organic Delivery From Ablation, Dilution, And Thermal Degradation, Chris Mehta, Anthony Perez, Glenn Thompson, Matthew A. Pasek

School of Geosciences Faculty and Staff Publications

A hypothesis in prebiotic chemistry argues that organics were delivered to the early Earth in abundance by meteoritic sources. This study tests that hypothesis by measuring how the transfer of organic matter to the surface of Earth is affected by energy-dissipation processes such as ablation and airbursts. Exogenous delivery has been relied upon as a source of primordial material, but it must stand to reason that other avenues (i.e., hydrothermal vents, electric discharge) played a bigger role in the formation of life as we know it on Earth if exogenous material was unable to deliver significant quantities of organics. For …

Evaluation Of Academic And Social Engagement In A Technology-Based Collaborative Approach To Inclusive Geoscience Field Learning, Anita Marie Stone Marshall

USF Tampa Graduate Theses and Dissertations

Field learning is an important aspect of geoscience education to teach or reinforce concepts and skills, and the highly social experience of field work can improve learning outcomes, create networks to support future academic success, and promote a sense of belonging in the geosciences. However, field learning presents significant barriers to participation for students with physical disabilities. The introduction of digital data collection and communication devices into traditional field work settings has created new opportunities to expand access to field learning experiences such as remote collaboration; a method of undertaking field work through collaborative teamwork and the use of digital …

Geochemical Modeling Of Fractional Magma Crystallization, Luke Varner

Undergraduate Journal of Mathematical Modeling: One + Two

Modern day geologists use many different modeling programs such as Geospatial Information Systems in addition to R (programming language) for a wide array of applications such as: projecting collected data for mapping, visualization, and trend prediction. Computational power for these modeling programs is derived from Calculus, Probability, and Statistics. The purpose of this paper is to provide a site-specific geochemical analysis of an igneous rock formation composed of two specific compositions allowing for the predictions of rock formation derived from the resultant geochemical model.

Evaporite Karst In Italy: A Review, Jo De Waele, Leonardo Piccini, Andrea Columbu, Giuliana Madonia, Marco Vattano, Chiara Calligaris, Ilenia D’Angeli, Mario Parise, Mauro Chiesi, Michele Sivelli, Bartolomeo Vigna, Luca Zini, Veronica Chiarini, Francesco Sauro, Russell Drysdale, Paolo Forti

International Journal of Speleology

Although outcropping rarely in Italy, evaporite (gypsum and anhydrite) karst has been described in detail since the early 20^th century. Gypsum caves are now known from almost all Italian regions, but are mainly localised along the northern border of the Apennine chain (Emilia Romagna and Marche), Calabria, and Sicily, where the major outcrops occur. Recently, important caves have also been discovered in the underground gypsum mines in Piedmont. During the late 80s and 90s several multidisciplinary studies were carried out in many gypsum areas, resulting in a comprehensive overview, promoting further research in these special karst regions. More recent …

Modeling Intrusive Geometries Of A Shallow Crustal Intrusion: New Evidence From Mount Ellsworth, Utah, Nathan Nushart

USF Tampa Graduate Theses and Dissertations

Surface displacements resulting from upper-crustal intrusion of melt are a paramount concern for communities and facilities located in or near active volcanic areas (e.g. Campi Flegrei, Yucca Mtn.). Study of active intrusions such as Campi Flegrei, Italy west of Mt. Vesuvius, is limited to remote observations through geophysical/geodetic procedures. While the surface displacement due to melt emplacement at depth can easily be determined, the geometries and depth of intrusions are often based on simplified assumptions (e.g. spheres and prolate or oblate ellipsoids). These models benefit from data constraining both the geometries of the individual intrusions, and the kinematics and mechanics …

New Insights Into Troglotella Incrustans Wernli & Fookes, 1992, A Fascinating Upper Jurassic-Upper Cretaceous Foraminifer, Felix Schlagintweit

Studia UBB Geologia

New data about the highly variable test morphology of the benthic foraminifer Troglotella incrustans WERNLI & FOOKES (Oxfordian-Lower Cenomanian) are presented, permitting an emended species/genus diagnosis. This concerns mainly the existence of a large final chamber with fistulose extensions that may follow the uniserial or the irregular-branching test part. The way of life of T. incrustans (cryptoendolithic vs. euendolithic) is discussed against the background of different existing models in the literature. The study is based on material (thin-sections and provided photographs) mainly from the Upper Jurassic of Austria, Italy, Romania, Ukraine, and also the type-locality of France.

Hydrologic And Microclimate Characterizations Of Thornton’S Cave, West-Central Florida (Usa), Dorien K. Mcgee

Studia UBB Geologia

A cave’s environment is controlled by a suite of factors unique to the environments in which they formed, including, but not limited to, regional geologic and climate settings. These factors collectively owe to wide variations in cave biology, geomorphology and overall speleogenesis. This report combines local climate, hydrologic, and CO₂ data collected over the course of a two-year study at Thornton’s Cave, a partially-flooded cave in the West-Central Florida karst belt, to characterize its current environment and yield insight regarding how changes in regional climate and hydrology impact its past and future speleogenesis. Data loggers continuously monitoring cave and …

Sedimentary Succesion Of The Lower Cretaceous Deposits From The North-Western Part Of Pădurea Craiului (Apuseni Mountains, Romania), Daniel F. Lazar, Ioan I. Bucur, Ioan Cociuba, Emanoil Sasaran

Studia UBB Geologia

Within the general succession of the Lower Cretaceous deposits from the Vârciorog-Dobreşti area (Pădurea Craiului Mountains), carbonate and terrigenous deposits were identified. The limestones were assigned to two distinctive lithostratigraphic units: the Valea Măgurii and Vârciorog formations. Based on the orbitolinids Palorbitolina lenticularis and Mesorbitolina texana their ages are assigned to the early Aptian, and respectively late Aptian–Albian. The terrigenous facies mainly include fine grained deposits (clays, siltites, marls) and, to a lesser extent, coarser ones (glauconitic sandstones and conglomerates), and they are attributed to the Ecleja and Vârciorog formations. The marls of the Ecleja Formation have been observed in …

Calcareous Nannofossils And Sedimentary Facies In The Upper Cretaceous Bozeş Formation (Southern Apuseni Mountains, Romania), Ramona Balc, Lóránd Silye, Luminita Zaharia

Studia UBB Geologia

The lithology, sedimentology and biostratigraphy of the Bozes Formation, which crop out in the SE Metaliferi Mountains (Apuseni Mts.) have been investigated in order to establish the age of the deposits and the depositional environment.

The sedimentary structures and facies are interpreted as indicating a deep-water depositional environment, representing part of a submarine fan lobe. Three facies assemblages have been identified and described. Calcareous nannofossils were used to determine the age of the investigated deposits. The presence of Lucianorhabdus cayeuxii and Calculites obscurus indicates the CC17 biozone, while UC13 Zone is pointed out by the continuous occurrence of Arkhangelskiella cymbiformis …

Agglutinated Foraminifera From The Northern Tarcău Nappe (Eastern Carpathians, Romania), Raluca Bindiu, Sorin Filipescu

Studia UBB Geologia

The Tarcău Nappe is the most important unit of the Carpathian flysch due to its size, stratigraphic, and tectonic complexity. Our purpose was to identify the major types of foraminifera assemblages in relation to the paleoenvironmental settings and their biostratigraphic potential. The identified assemblages are characteristic to the Cretaceous and Paleogene, consisting mostly of benthic agglutinated and, in lower proportions, benthic calcareous and planktonic species. Local abundances of Glomospira specimens allowed the correlation of the examined strata to the early Eocene “Glomospira event” described from the Carpathians in Poland, Morocco, and Labrador. Rzehakina fissistomata (Grzybowski) identified at Palma makes …

Morphological Specification Of Chinianella Scheympflugi Hofmann, 1994, A Late Jurassic (?Earliest Cretaceous) Dasycladalean Alga Of The Western Tethyan Domain, Felix Schlagintweit

Studia UBB Geologia

The dasycladalean alga Chinianella? scheympflugi was described by Hofmann (1994) from the Tithonian of the Ernstbrunn Limestone of Lower Austria. This alga, so far unreported besides its type-locality, is reported from the Late Jurassic of Poland, the Northern Calcareous Alps of Austria, Crimea (Ukraine), and Greece (Parnassos Zone). Facies are well-agitated outer platform habitats (peri-reefal and back-reefal facies). The cylindrical thallus consists of three parts: a sterile Salpingoporella-like basal part (stalk), a fertile Chinianella-type main portion and a short sterile top part. The transition from the stalk to the main thallus portion is well marked and abrupt. The stratigraphic range …

New Data On Facies Development And Micropaleontology Of The Eastern Margin Of The Getic Carbonate Platform (South Carpathians, Romania): Case Study Of Mateiaş Limestone, Ioan I. Bucur, Daniela Beles, Emanoil Sasaran, Constantin Balica

Studia UBB Geologia

Mateiaş Limestone represents a lithostratigraphic unit included in the Braşov Series, which is a component of the eastern end of the Getic Nappes’ cover (the Getic carbonate platform). The study of the Mateiaş Limestone in Hulei-Mateiaş-Măgura area has evidenced three main facies, and five microfacies types. The Kimmeridgian (possibly also Early Tithonian) age of the Mateiaş Limestone has been assigned based on a microfossil association identified in thin sections. The regional framework, as well as their sedimentological and micropaleontological features point to the deposition of these limestones on shelf margin and slope environments; the succession in the studied area corresponds …

Late Jurassic–Early Cretaceous Foraminifera From Štramberk-Type Limestones, Polish Outer Carpathians, Daria Ivanova, Boguslaw Kolodziej

Studia UBB Geologia

Foraminifera studies were carried out on the Štramberk-type limestones which occur as pebbles to small boulders (exotics) within the uppermost Jurassic–Palaeogene flysch deposits of the Polish Outer Carpathians. The studies were focused on foraminifera from (1) reef and peri-reef facies, and (2) lagoonal algal-foraminiferal facies. The paper deals with 34 species (including 8 in open nomenclature) representing 30 genera, 22 families, 14 superfamilies, 11 suborders, and 7 orders. A more precise age determination has been obtained for 30 exotics, representing a Tithonian (mostly) to Valanginian age. Foraminiferal assemblages from at least two exotics suggest a Valanginian age as indicated by …

Mammut Borsoni (Hays 1834) From The Early Pliocene Of Husnicioara (Mehedinţi District, Romania), Vlad Codrea, Florina Diaconu

Studia UBB Geologia

A mastodon tooth has been found at Husnicioara coal open pit, in Mehedinţi district (southwestern Romania). It originates from the Lower Pliocene (Dacian) gravel and sand deposits lying just above the coal bed IV, mined in this quarry. The tooth exposing zygodont features undoubtedly belongs to Mammut borsoni (“Borson’s mastodont”). Although this species is very common in the Pliocene vertebrate faunas from this part of Europe, until now it was missing from the Lower Pliocene (Dacian) assemblage’s lists in our country.

On The Cretaceous Occurrences Of Ammogloborotalia Zheng, 2001 (Foraminifera), Michael A. Kaminski, Claudia Cetean, Andrew Henderson, Sorin Filipescu

Studia UBB Geologia

Three species of agglutinated foraminifera from Cretaceous deep-water deposits that have been described as trochamminids are here transferred to the genus Ammogloborotalia ZHENG, 2001. These species are Trochammina abrupta GEROCH, 1959; Trochammina quinqueloba GEROCH, 1959, and Ammoanita globorotaliaeformis Gradstein and Kaminski, 1999. A fourth species, Ammogloborotalia sp.1, which is probably a new species from the Turonian of the southern East Carpathians of Romania is reported here for the first time. We hereby extend the known stratigraphic range of the genus Ammogloborotalia to the Late Jurassic (Tithonian).

Uppermost Jurassic-Lower Cretaceous Carbonate Deposits From Fara San Martino (Maiella, Italy): Biostratigraphic Remarks, Roberta Bruni, Ioan I. Bucur, Alain Preat

Studia UBB Geologia

The Uppermost Jurassic-Lower Cretaceous limestone succession in the Maiella region of Italy has been investigated in a profile covering more than 400 m stratigraphical thickness at Fara San Martino. The succession mainly consists of peritidal limestones, intertidal and supratidal sequences being dominant, together with subtidal lagoonal facies. As a consequence, the microfossil assemblages are generally poorly developed, Microfossils occur within the subtidal lagoonal facies of this suite of restricted sediments. This feature led us to recognise five informal biostratigraphic intervals, which are facies related – instead of biozones, each of the intervals being characterized by specific micropaleontological associations. The occurrence …

Biostratigraphy Of The Cretaceous Deposits In The Western Transylvanides From Ampoi Valley (Southern Apuseni Mountains, Romania), Ramona Balc, Erika Suciu-Krausz, Florin Borbei

Studia UBB Geologia

The present study is an approach of the issues related to the biostratigraphy of the Western Transylvanides. The research provided exact age data for the Feneş Formation, Valea lui Paul Formation, Bozeş Formation and Râmeţi Formation. The age of the formations was established based on the calcareous nannoplankton assemblages in Barremian-Campanian range. The lithological features together with the new age data allowed us to modify the boundaries between formations; accordingly the knowledge on the structure of South Apuseni Mountains required changes, too. The new data also imply the modification of the existent geological maps of the region. Based on the …
