Signatures in the Subsurface - Big & Small Data Approaches for the Spatio-Temporal Analysis of Geologic Properties & Uncertainty Reduction

Creator:

Rose, Kelly Kathleen

Abstract:

Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....

Geomicrobiology of marine sediment containing methane

Creator:

Briggs, Brandon R.

Abstract:

Marine sediments contain an abundance of methane that is biologically produced and plays a significant role in the global carbon cycle. Microbes responsible for the carbon cycle in marine sediments, and the processes that they carry out, need to be characterized in order to fully understand the role of this...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:

Seabrook, Sarah

Abstract:

Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...
