Dissolved And Particulate Phosphorus Distributions And Elemental Stoichiometry Throughout The Chukchi Sea, Meryssa Piper
Dissolved And Particulate Phosphorus Distributions And Elemental Stoichiometry Throughout The Chukchi Sea, Meryssa Piper
Theses and Dissertations
As the only gateway of material, particularly nutrients, from the Pacific to the Arctic Ocean, the biological and chemical transformations that occur within the Chukchi Sea are critical for understanding Arctic ecosystems. This study examines the biogeochemical cycling of the macronutrient phosphorus (P) relative to carbon and nitrogen in the eastern Chukchi Sea during the ICESCAPE’s mission. Sea ice and water column dissolved and particulate phosphorus samples were collected during two summer expeditions in 2010 (n=593) and 2011 (n=989). Despite being a landlocked marginal sea, the P pool present within the Chukchi Sea was substantially modified by biological processes with …
Factors Contributing To Interannual Variability In The Abundance Of Bay Anchovy (Anchoa Mitchilli) Larvae, Steven B. Vega Jr.
Factors Contributing To Interannual Variability In The Abundance Of Bay Anchovy (Anchoa Mitchilli) Larvae, Steven B. Vega Jr.
Theses and Dissertations
Coastal ecosystems have been subject to increasing stressors over recent decades due to coastal development, human population growth, and climate change. Improving scientific understanding of the environmental factors which influence the productivity of fish populations in coastal ecosystems is vital to their prudent management, especially as the potential influence of anthropogenic climate change grows. Estuaries serve as critical habitats for many fishes of primary ecological, economic, and recreational importance. One such fish, the planktivorous Bay Anchovy (Anchoa mitchilli), is abundant along the Atlantic and Gulf coasts of the US and is a key prey resource for many estuarine and coastal …
Fate And Behavior Of Silver Nanoparticles To The Estuarine Organisms, Prorocentrum Minimum And Crassostrea Virginica, Shelby Victoria Butz
Fate And Behavior Of Silver Nanoparticles To The Estuarine Organisms, Prorocentrum Minimum And Crassostrea Virginica, Shelby Victoria Butz
Theses and Dissertations
Nanoparticles are known to be entering the environment and are shown to have adverse effects on aquatic organisms (Fabrega et.al. 2011, Lapresta-Fernandez et.al. 2012, Matranga and Corsi 2012, Moore 2006). The purpose of this study was to quantify the uptake of AgNPs by two estuarine organisms and determine the associated toxic effects of accumulation. There are multiple procedures for nanoparticle (NP) synthesis that involve various core and surface materials, which result in various characteristics such as size, shape, and surface coating. In this study silver nanoparticles (AgNPs) were synthesized by a chemical reduction of silver salts and characterized in stock …
