Growth And Reproduction In Gulf Of Mexico Black Corals (Antipatharians) In Field And Laboratory Studies, Victoria E. Salinas
Growth And Reproduction In Gulf Of Mexico Black Corals (Antipatharians) In Field And Laboratory Studies, Victoria E. Salinas
Theses and Dissertations
Black corals provide an important ecosystem of marine life and are found throughout all the oceans of the world at depths between 2 and 8,600 m. However, little is understood about their life history and the factors that control the distribution of black corals, particularly in the Gulf of Mexico (GoM). Given the impacts of the Deepwater Horizon oil spill on soft corals (e.g., black corals and octocorals) in the GoM, studies of their growth and reproductive biology in both natural and aquaculture environments are crucial for restoration efforts. The objectives of this study were to examine reproductive processes, compare …
Enabling High Quality Oxygen Measurements During Robotic Based Studies Of Ocean Ecological And Biogeochemical Processes, Brianna A. Alanis
Enabling High Quality Oxygen Measurements During Robotic Based Studies Of Ocean Ecological And Biogeochemical Processes, Brianna A. Alanis
Theses and Dissertations
Dissolved oxygen is an essential parameter necessary for understanding marine ecological and biogeochemical processes. New robotic vehicles and autonomous platforms are being applied to an even wider range of ecological and biogeochemical studies. Thus, arises the opportunity for matching the best possible oxygen sensing techniques and methods to these new platforms. In so doing, we can enable both more targeted and higher resolution oxygen measurements than previously possible and potentially use oxygen measurements for a wider range of applications, including in situ incubation experiments and primary productivity measurements. This thesis tested three different oxygen sensors in a trade study for …
Distributions Of Polychaetes As A Function Of Sediment Composition In A Subtropical Lagoon, Anthony William Cox
Distributions Of Polychaetes As A Function Of Sediment Composition In A Subtropical Lagoon, Anthony William Cox
Theses and Dissertations
Fine-grained organic-rich sediments (FGORS) in the Indian River Lagoon (IRL), Florida, the human activities and nutrient inputs and have a varied composition, including water content, silt-clay content, and organic matter. When these constituents reach, by weight, 75%, 60% dry, and 10% dry, respectively, this is sometimes referred to as IRL “muck”. Many polychaetes inhabit the benthic sediments of estuaries and must tolerate various degrees of FGORS. The Cox IRL Muck Index (CMI) is proposed as a mechanism for determining the organic sediment tolerances of infaunal species in a simple and direct manner. IRL muck will have a minimum CMI of …
