The Impact of Surface Ocean Mixing on Phytoplankton Communities and Associated Carbon Pools

Creator:

VerWey, Brian J.

Abstract:

Deep mixing events in the ocean’s surface layer act as physical drivers of carbon export by detraining dissolved and particulate organic matter, including surface phytoplankton communities, to depth. Once removed from the sunlit surface ocean environment, phytoplankton accumulation rates are dependent on the relative contributions of loss processes, such as...

Analysis of Culturally Derived Speleothems by INAA and ICP-MS, a Multi-Analytical Approach

Creator:

Nation, Humberto E.

Abstract:

Over the last two decades, archaeologists have documented the widespread ancient Maya practice of collecting cave formations (speleothems) from ritually important caves and transporting them to their settlements. Little is known about their specific uses within settlements, but it is hypothesized that these objects convey a degree of sanctity from...

Quantifying Carbon Production in Marine Ecosystems Using Expressions of Phytoplankton Physiology

Creator:

Penta, William Bryce

Abstract:

Phytoplankton initiate the marine carbon cycle by fixing carbon dioxide into biologically available compounds. These abundant single celled organisms mediate carbon flux from the atmosphere to the deep ocean and are the base of the marine food web, supplying new carbon to higher trophic levels. Phytoplankton are highly diverse and...
