Climate Change of the South Polar Region in response to topographic and cryospheric forcings during the Paleocene-Eocene thermal maximum
Brown, Mikaela; 0000-0001-6060-500X (2019-05-03)The Paleocene-Eocene thermal maximum (PETM) occurred approximately 56 Ma and is marked by an estimated global temperature increase of 5 °C, a large negative carbon and oxygen excursion, and deep-sea carbonate dissolution. ... -
The Effect Of Freshwater Input On δ18o Distribution At The Younger Dryas
Soni, Anand (Environmental & Earth Science, 2014-07-14)The Younger Dryas cooling event (~12.9-11.5 δ18O ka BP) is a recognized example of an abrupt decline of the Atlantic meridional overturning circulation and thus may serve as an analog for expected rapid future climate ... -
Effects Of Climate Change And Perturbation In Biogeochemical Cycles On Oxygen Distribution And Ocean Acidification
Beaty-Sykes, Teresa Marie (Environmental & Earth Science, 2014-12)Dissolved oxygen (DO) concentration in the ocean is an important component of the marine biogeochemical cycles. In this study a global oceanic carbon cycle model (HAMOCC 2.0) was used to address how oxygen minimum zones ... -
GEOSPATIAL ANALYSIS OF POTENTIAL FLOODING FROM STORM SURGE AND SEA-LEVEL CHANGE ON THE TEXAS COAST BY 2100
Prykhodko, Gennadii; 0000-0001-5587-6331 (2020-05-14)Tropical cyclones pose a major hazard to the State of Texas. Anthropogenic climate change and global warming have the potential to increase extreme weather events and lead to enhanced flood hazard zones. This study aims ... -
IMPROVING REGIONAL HYDROLOGY FORECASTING FOR THE NORTH CENTRAL TEXAS REGION UTILIZING CONDITIONAL ENSEMBLE STREAMFLOW AND HYDROMETEOROLOGICAL CONDITION PREDICTIONS WITH ARTIFICIAL NEURAL NETWORK MODELING
Fincannon, Tyler (2017-05-10)The predictive skill of hydrologic variables such as streamflow and soil moisture, in North Central Texas, has improved substantially in the recent decades. However, substantial model-data biases are still present during ... -
On The Sensitivity Of Ocean Circulation To Arctic Freshwater Pulses During The Paleocene/Eocene Thermal Maximum
Cope, Jesse Tiner (Environmental & Earth Science, 2010-03-03)The Paleocene/Eocene Thermal Maximum (PETM) corresponds to a period characterized by extreme global warming caused by a massive carbon input into the ocean and atmosphere. Approximately 55 Ma in the early Cenozoic, evidence ... -
SENSITIVITY OF OXYGEN MINIMUM ZONES DUE TO CARBON DIOXIDE RADIATIVE FORCING USING CESM 1.2
Wolfe, Kristina K.; 0000-0003-0865-2786 (2019-04-25)Anthropogenic-induced climate change is occurring at an unprecedented rapid rate, compared to the geologic past. In this study, CO2 stabilization scenarios (1x, 2x, and 4x preindustrial atmospheric pCO2 levels) utilizing ... -
Sensitivity Of The Late Permian Climate To Tectonic And Radiative Forcing Changes: Implications For The Mass Extinction
Osen, Angela (Environmental & Earth Science, 2014-12)The largest mass extinction occurred near the Permian-Triassic boundary (ca. 252 Ma). Significant carbon isotope shifts indicate that perturbations in the carbon cycle occurred during the Late Permian and persisted into ... -
Sensitivity of the Younger Dryas climate to changes in freshwater, orbital, and greenhouse gas forcing in comprehensive climate models
Hughlett, Taylor Michelle; 0000-0002-7973-954X (2016-05-11)The Younger Dryas cooling event (~12,900 years before present) was the most recent abrupt climate change in the geologic record where climate for the Northern Hemisphere returned to a near-glacial state. The cause of this ... -
Simulation Of Climate Across the Permian-Triassic Boundary with a Focus on Phytogeographical Data Analysis
Gautam, Mitali Dinesh; 0000-0001-5357-7506 (2018-12-06)The present study aims at reconstructing the paleoclimate across the Permian-Triassic Boundary (PTB, 251.9 ± 0.024 Ma) which encompasses one of the major mass extinction events of the Earth’s history. Results are analyzed ... -
Trends In Seasonal Climate Variance In The Subtropical Reservoir Joe Pool Lake, Texas: Implications Dissolved Oxygen And Nutrient Distribution
Ball, RebekahThe primary causes of seasonal variance in temperature, hydrological cycle, and nutrient distribution of lakes, and the processes explaining these changes including climate change and land use changes have been investigated ...
