Salt Marsh Health And Biomass Responses To A Changing Environment, Gwen Joelle Miller
Salt Marsh Health And Biomass Responses To A Changing Environment, Gwen Joelle Miller
Theses and Dissertations
Coastal salt marshes are important ecosystems not only for their aesthetic beauty but also for their ecosystem services that they provide including improving water quality, providing protection from storm surges and hurricanes, and carbon sequestration. With climate change, including drought, warmer temperatures and sea-level rise, these systems are going to be impacted. Understanding how salt marshes will respond, or already have responded, to climate change will help us be better prepared for the future. By scripting a model to project how marshes may migrate with sea-level rise, I discover that salt marshes within Beaufort and Jasper counties, South Carolina will …
Larval Fish Mortality And Vertical Chlorophyll Structures: Reexamination Of The Stable Ocean Hypothesis In The Southern California Current, Brendan D. Turley
Larval Fish Mortality And Vertical Chlorophyll Structures: Reexamination Of The Stable Ocean Hypothesis In The Southern California Current, Brendan D. Turley
Theses and Dissertations
The natural mortality of fishes is an important component for understanding population dynamics. The larval stages of pelagic fishes living in the open ocean are particularly vulnerable to high rates of mortality, and fluctuations in these rates are thought to exert a large influence on the number of fish maturing into the spawning population. Early stage larval fishes are thought to undergo a critical period after hatching when they must find food or succumb to starvation. While the availability of suitable food for larval fishes is, on average, too low in the open ocean to support survival, patchy distributions of …
Energetic Consequences Of Human Impacts For Bioindicator Atlantic Ghost Crab (Ocypode Quadrata), Mustafa Remzi Gül
Energetic Consequences Of Human Impacts For Bioindicator Atlantic Ghost Crab (Ocypode Quadrata), Mustafa Remzi Gül
Theses and Dissertations
Human activities have caused notable changes in ecosystems globally over the past century, which cause substantial ecological issues. The degree of these ecological issues is often investigated using the responses of bioindicator species. Bioindicator species often reduce their population densities and individual sizes as a response to the human disturbance. Observing these variations in the demographics is often an effective way to measure the strength of the ecological changes. However, they do not provide any mechanistic reason (s) for the shifts in the demographics, which is important for making predictions about responses of the species to the future conditions. Therefore, …
The Impacts Of Episodic Floods, Droughts, Turbidites On Organic Carbon Burial Over The Past 2,000 Years In The Santa Barbara Basin, California, Caitlyn Sarno
Theses and Dissertations
Over the past several millennia, Southern California has experienced episodic climate that have influenced the magnitude and composition of terrestrial and marine material that ultimately reaches ocean sediments. Here, we analyze elemental concentrations, stable isotopes, and n-alkane lipids as tracers of terrestrial and marine sources in drought, turbidite, and flood horizons from a well-dated sediment core in the Santa Barbara Basin (SBB) that spans the last 2,000 years. Stable isotopes (δ13C and δ15N), indicate that more terrestrial organic carbon (OC) input occurred during floods relative to non-event periods, while bulk C/N ratios remained relatively constant (~10). Long chain n-alkanes, (C27, …
Upper Ocean Dynamics And Mixing In The Arabian Sea During Monsoons, Corinne Beverly Trott
Upper Ocean Dynamics And Mixing In The Arabian Sea During Monsoons, Corinne Beverly Trott
Theses and Dissertations
The Indian summer monsoon is a complex, nonlinear phenomenon involving atmospheric, oceanic, and land-based interactions from June through September. During this period, a strong low-level jet known as the Findlater Jet develops over the western Arabian Sea, advecting seasonally high quantities of warm, moist air to the Indian subcontinent, leading to the largest precipitation rates on the planet. The winds associated with the Findlater Jet seasonally strengthen the Arabian Sea eddy field, known for its intensity and variability. Comparison between the eddies in the western Arabian Sea during monsoon regimes of varying intensities revealed more high-amplitude eddies in strong (high-rainfall) …
