Projecting Regions Of North Atlantic Right Whale, Eubalaena Glacialis, Habitat Suitability In The Gulf Of Maine In 2050, Camille Ross
Projecting Regions Of North Atlantic Right Whale, Eubalaena Glacialis, Habitat Suitability In The Gulf Of Maine In 2050, Camille Ross
Honors Theses
North Atlantic right whales (Eubalaena glacialis) are endangered. Understanding the role environmental conditions play in habitat suitability is key to determining the regions in need of protection for conservation of the species, particularly as climate change shifts suitable habitat. This thesis uses three species distribution modeling algorithms, together with historical data on whale abundance(1993 to 2009) and environmental covariates to build monthly ensemble models of past E. glacialis habitat suitability in the Gulf of Maine. Then, the models are projected onto the year 2050 for a range of climate scenarios. Specifically, the distribution of the species was modeled …
Mathematical Modeling Of Emiliania Huxleyi And A Host-Specific Virus, Julia Middleton
Mathematical Modeling Of Emiliania Huxleyi And A Host-Specific Virus, Julia Middleton
Honors Theses
The world’s oceans provide the basis for life on the planet. One microscopic algae, the coccolithophores, and Emiliania huxleyi in particular, is a major source of carbon drawdown in the context of the global carbon cycle and account for a significant amount of the primary production in oceanic ecosystems. We know that the oceans are packed with marine viruses and they have an important role in the rise and fall of plankton populations but current mathematical models do not accurately account for virus-host interactions when predicting plankton blooms. Therefore I am using model optimization and comparison techniques to evaluate current …
Development Of A Spectral 2-D Fast Fourier Transform Analysis For Sand Ripple Morphology Interpretation, Christopher M. Englert
Development Of A Spectral 2-D Fast Fourier Transform Analysis For Sand Ripple Morphology Interpretation, Christopher M. Englert
Honors Theses
A MATLAB-based 2-Dimensional Fast Fourier Transform spectral analysis is developed and tested for its applicability to bedform morphology and hydrodynamic data from a hydrodynamically complex field site. The aspects of the procedure tested are (1) the use of an 8 sub-region arrangement for analysis versus five other arrangements, (2) the procedure for averaging the wavelength-and-orientation outputs from each sub-region to produce a single representative value for each image, (3) methods for eliminating and/or filtering poor quality data, and (4) the procedural steps in the spectral analysis that can appropriately incorporate automation versus manual involvement and interpretation. The automated technique is …
