Abstract : This report describes the technical accomplishments of the subject grant. This work forms a part of a broader, ongoing effort to more completely describe the physiological responses of marine phytoplankton species to the time-course of natural solar radiation variation on time scales of minutes to days. The investigative approach involves in situ instrumentation, laboratory observations and computer models. Collaborators on this ongoing project include Daniel Kamykowski, Thomas Curtin, Gerald Janowitz and Hidekatsu Yamazaki. The objective of the work under the subject grant was to develop the capability to conduct simultaneous, in situ comparison studies of the photosynthetic responses within and between selected phytoplankton species under natural irradiance fluctuation utilizing the Self-contained Underwater Photosynthesis Apparatus (SUPA). This objective was met by fabricating a twin SUPA based on the existing design and incorporating the necessary modifications to hardware and software to permit simultaneous operation from existing support equipment.
