Transformation Of Nonlinear Waves In The Presence Of Wind, Current, And Vegetation, Haifei Chen
Transformation Of Nonlinear Waves In The Presence Of Wind, Current, And Vegetation, Haifei Chen
Electronic Theses and Dissertations
Accurate prediction of extreme wave events is crucial for the safe maritime activities and offshore operations. Improved knowledge of wave dissipation mechanisms due to breaking and vegetation leads to accurate wave forecast, protecting life and property along the coast. The scope of the thesis is to examine the wave transformations in the presence of wind, current, and vegetation, using a two-phase flow solver based on the open-source platform OpenFOAM. The Reynolds-Averaged Navier-Stokes (RANS) equations are coupled with a Volume of Fluid (VOF) surface capturing scheme and a turbulence closure model. This RANS-VOF model is adapted to develop a numerical wind-wave-current …

Oyster Aquaculture Site Selection Using Landsat 8-Derived Sea Surface Temperature, Turbidity, And Chlorophyll A., Jordan Snyder
Electronic Theses and Dissertations
Remote sensing data is useful for selection of aquaculture sites because it can provide water-quality products mapped with no cost to users. However, the spatial resolution of most ocean color satellites is too coarse to provide usable data within many estuaries. The more recently launched Landsat 8 satellite has both the spatial resolution and the necessary signal to noise ratio to provide temperature, as well as ocean color derived products along complex coastlines. The state of Maine (USA) has an abundance of estuarine indentations (~3,500 miles of tidal shoreline within 220 miles of coast), and an expanding aquaculture industry, which …
Revisiting Ocean Color Algorithms For Chlorophyll A And Particulate Organic Carbon In The Southern Ocean Using Biogeochemical Floats, Nils Haëntjens
Revisiting Ocean Color Algorithms For Chlorophyll A And Particulate Organic Carbon In The Southern Ocean Using Biogeochemical Floats, Nils Haëntjens
Electronic Theses and Dissertations
The Southern Ocean (SO, oceans south of 30 oS) ecosystem plays a key role in global carbon cycles by sinking a major part (43 %) of the anthropogenic CO2, and being an important source of nutrients for primary producers. However, undersampling of SO biogeochemical properties limits our understanding of the mechanisms taking place in this remote area. The Southern Ocean Carbon and Climate Observing and Modeling project (SOCCOM) has been deploying a large number of autonomous biogeochemical floats to study the SO (as of December 2016, 74 floats out of 200 have been deployed). SOCCOM floats measurements …
