Microbial Analysis Of Surfactant-Associated Bacteria In The Sea Surface Microlayer And Remote Sensing Of Associated Slicks, Georgia Parks
Microbial Analysis Of Surfactant-Associated Bacteria In The Sea Surface Microlayer And Remote Sensing Of Associated Slicks, Georgia Parks
HCNSO Student Theses and Dissertations
The sea-surface microlayer (SML) is the boundary layer at the air-sea interface where many biogeochemical processes occur. Many organisms (e.g., bacteria) produce surface active agents (surfactants) for life processes, which accumulate in the SML and dampen short gravity-capillary waves, resulting in sea surface slicks. Synthetic aperture radar (SAR) is capable of remotely sensing these features on the sea surface by measuring reflected backscatter from the ocean surface in microwaves. This study coordinates SAR overpasses with in situ SML and subsurface (SSW) microbial sample collection to guide subsequent analysis after 16s rRNA sequencing on the Illumina MiSeq. In April …
A Comparison Of Qualitative And Quantitative Data Collection Techniques To Assess Mapping Accuracy In The Florida Keys, Ian K. Rodericks
A Comparison Of Qualitative And Quantitative Data Collection Techniques To Assess Mapping Accuracy In The Florida Keys, Ian K. Rodericks
HCNSO Student Theses and Dissertations
Benthic habitat maps provide the spatial framework for many research science and management activities in coastal areas such as coral-reefs. Accuracy, the degree to which information on a map matches true or accepted values, of benthic habitat maps is important because often times the map will be used in decision-making processes about how we manage our marine resources. It is critical that some measure, such as the accuracy, of the map be known in order to give a sense of how the overall map portrays the seascape. This study compared the accuracy in the following map classes; major structure, major …
Coral Genotype Influence On Growth And Stress Resistance In Acropora Cervicornis: Investigating Potential Energy Tradeoffs, Peter T. Grasso
Coral Genotype Influence On Growth And Stress Resistance In Acropora Cervicornis: Investigating Potential Energy Tradeoffs, Peter T. Grasso
HCNSO Student Theses and Dissertations
Over the last few decades coral reefs have faced unprecedented declines in health due to natural and anthropogenic sources. Until recently few studies have examined genotypic variation of growth and thermal stress resistance in Acropora cervicornis. This study aims to assess the potential for energy trade-offs between growth and thermal stress resistance by following 120 coral fragments from 12 genotypes of Acropora cervicornis over the course of 15 months to determine average growth rates for each genotype. Following the completion of the growth observation a bleaching event occurred in the lower Florida Keys providing the opportunity for examining thermal …
