Final deglaciation of the Scandinavian Ice Sheet and implications for the Holocene global sea-level budget

Creator:: Cuzzone, Joshua K., Clark, Peter U., Carlson, Anders E., Ullman, David J., Rinterknecht, Vincent R., Milne, Glenn A., Lunkka, Juha-Pekka, Wohlfarth, Barbara, Marcott, Shaun A., and Caffee, Marc
Abstract:: The last deglaciation of the Scandinavian Ice Sheet (SIS) from ∼21,000 to 13,000 yr ago is well-constrained by several hundred ¹⁰Be and ¹⁴C ages. The subsequent retreat history, however, is established primarily from minimum-limiting ¹⁴C ages and incomplete Baltic-Sea varve records, leaving a substantial fraction of final SIS retreat history...

Sex determination in Nile tilapia, Oreochromis niloticus: gene expression, masculinization methods, and environmental effects

Creator:: Sánchez, Wilfrido M. Contreras
Abstract:: Sex differentiation in fish is a labile process that allows sex inversion in several species. The inherent capacity of fish germ cells to differentiate into oocytes or spermatocytes constitutes a key factor allowing for functional sex inversion. This thesis set out to determine the mechanism involved in steroid-induced sex differentiation...

Nile tilapia (Oreochromis niloticus) production in tropical microcosms fertilized with rabbit excreta

Creator:: Franco, Luis
Abstract:: This investigation explored the use of microcosms as a tool for studying the dynamics of tropical aquaculture ponds. The potential use of rabbit excreta as a pond fertilizer in integrated farming systems was also investigated. Twelve insulated fiber glass tanks were utilized as microcosms to simulate earthen ponds. Seven hand-sexed...

The Heart Beat of the Megafloods

Creator:: Valdez Hernandez, Saray
Abstract:: Marine sediment core OC1706B-02J ( 46° 15.4178 N, 125° 42.4543 W, at water depth 2263m), was collected on the lower continental slope near the base of the Willapa Canyon. It is a rapidly accumulating site (~30cm/kyr) located near the thrust front of the Cascadia Subduction Zone. The site is also...

An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

Creator:: Cuzzone, Joshua K.
Abstract:: The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...

Analyzing large paleoclimate datasets : implications for past and future climate change

Creator:: Shakun, Jeremy D.
Abstract:: This dissertation presents the results of statistical analyses of large climate datasets from two time intervals – the 20th century instrumental record and the proxy record of the last deglaciation – in order to understand the forcings and mechanisms of past climate variability. A longstanding question in climate dynamics concerns...

Management alternatives for the yellowfin tuna fishery in the Mexican Exclusive Economic Zone

Creator:: Garcia-Martinez, Salvador
Abstract:: Tuna fishery is an important activity worldwide. In the eastern Pacific Ocean the effort applied by the Pacific Ocean fleet to catch tuna fish is considerable. The eastern Pacific tuna fleet harvests throughout the oceans and captures an important fraction of this resource. For instance, in 1980 the total catch...

North Atlantic Climate and Cryosphere Variability Over the Past 20,000 Years

Creator:: Sinclair, Gaylen
Abstract:: Reconstructing the sensitivity of past climate to forcings, and of ancient glaciers and ice sheets to this climate, can allow us to better understand the range of climate and cryosphere behavior we may see in the coming centuries. The Arctic is a region of particular importance due to its well-documented...

Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

Creator:: Mustafa, Nizar Ahmad
Abstract:: Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...
