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...

Physiological characterization of the mixotrophic dinoflagellate Amphidinium carterae

Creator:

Tornberg, Emma C.

Abstract:

Marine primary production can be modeled and estimated using remotely-observable physiological signatures such as chlorophyll and carbon. Current models are based on strict physiological relationships based on photoautotrophic phytoplankton, and discrepancies between modeled and in situ data may stem from unaccounted-for physiological deviations from photoautotrophy. Mixotrophic phytoplankton can obtain energy...
