The Influence Of Bottom Type And Water Column Stratification On Reef Fish Community Structure At Gray’S Reef National Marine Sanctuary, Bridget Campbell
The Influence Of Bottom Type And Water Column Stratification On Reef Fish Community Structure At Gray’S Reef National Marine Sanctuary, Bridget Campbell
Honors Theses
Understanding the physical and oceanographic differences across reef habitats can help researchers assess how those differences influence fish distribution and community structure, which leads to a better understanding of what a healthy reef system looks like. The traditional methods used to assess fish communities on temperate reefs are limited and often focus solely on either the reef structure or water column conditions alone. An assessment of both data sets yields a more complete understanding of the ecosystem as a whole. In this study, Gray’s Reef National Marine Sanctuary (GRNMS) was surveyed both inside and outside a Marine Protected Area (MPA) …
The Effect Of Radium Partitioning On Hydrothermal Fluid Flow Determination Across Guaymas Basin, Charlotte R. Kollman
The Effect Of Radium Partitioning On Hydrothermal Fluid Flow Determination Across Guaymas Basin, Charlotte R. Kollman
Electronic Theses and Dissertations
Analysis of the distribution of radium through sedimentary porewater profiles is a promising method for constraining diffuse discharge/recharge flow rates in hydrothermal settings; these parameters are critical for evaluating hydrothermal circulation and its chemical and biological implications. The short-lived 224Ra (T1/2 = 3.54 days) is an effective tracer due to its behavior in marine environments and changes in activity due to ingrowth/decay. However, the distribution of radium may be influenced by its varying solid:aqueous partitioning coefficients (Kd) and is critical to understand for any study utilizing radium as a tracer. This project explores Kd across the hydrothermally active Guaymas Basin …
