 | The tasks outlined in the ONR Grant entitled 'Marine Phytoplankton Culture Collection: Resources for Algal Biotechnology' have been completed. The Provasoli-Guillard National Center for culture of Marine Phytoplankton (CCMP) has provided both starter cultures and large volume batch cultures for ONR scientists working in the areas of algal biotechnology and nanofabrication. In addition, we provided culturing assistance via the telephone and e-mail for ONR ... |

|
| The long-term goals for my ONR project were to quantify the light scattering properties of suspended calcite particles in the sea; and to predict suspended calcite concentrations in space and time. Calcite is one of the most abundant minerals on earth, and much of it is biogenically formed by ubiquitous phytoplankton known as coccolithophores. These picoplankton produce micron-sized scales known as coccoliths which represent a major source of optical scattering ... |

|
| The objective of this research is to identify open ocean and coastal water features appearing within photographs taken during U.S. Space Shuttle missions (1981-1991) and to investigate their geographic and temporal occurrences. In addition to a comprehensive review of these data, to be submitted for publication in a peer-reviewed journal, this work will culminate in a database of coastal and ocean photographic data that may be accessed with standard desk-top ... |

|
| The optical properties of surface waters are strongly influenced by biogenic particles, hence by particle dynamics and by changes in cellular optical characteristics. Our principal objective was to describe spatial and temporal variability in water clarity, phytoplankton biomass and particle dynamics in terms of downwelling irradiance and upwelling radiance, measured at the surface in coastal and oceanic waters with newly-developed drifting and moored radiometers. Toward this end, extensive optical and ... |

|
| We have measured input values and coefficients for each interface and layer such that a simple implementation of the model can be tested at several wavelengths throughout the visible spectrum. We argue that with knowledge of the in-water optical properties, spectral reflectance and fluorescence signatures of benthic organisms, water leaving radiances from shallow coastal waters contain ecological information concerning benthic community biomass, primary production and diversity. In addition to the ... |

| Effects of Asphericity on Single-Particle Polarized Light Scattering |

|
| Polarized light scattering from individual particles has been analyzed to determine the effects of particle shape. Flow cytometric techniques were used on samples of spherical microspheres and naturally occurring marine algae. An analog of the depolarization ratio was obtained by using crossed polarizers in the source and detector of the flow cytometer. Results suggest that differences between the polarized light scattering of spheres and aspherical particles are not discernible unless ... |

|
 | The goal of this project was to understand the responses of phytoplankton to variations in irradiance so as to describe how physiological and optical characteristics of phytoplankton reflect physical forcing and particle dynamics. The application of this understanding is in using optical measurements to describe physical-biological coupling in the sea. The objectives of the program were to interpret measurements of fluorescence, beam attenuation, and photosynthesis versus irradiance (P-I) in terms ... |

|
| Using maps of respiratory electron transport activity in the coastal upwelling areas off Oregon, southern California, and northwest Africa, the author has been able to distinguish rising freshly upwelled waters from the waters of a relaxed upwelling event. Using measurements of ETS activity deep under the Peru Current, and oxygen and current measurements in the basins of the southeastern Pacific Ocean the author has calculated that the 2000 m water ... |

|
| The objective of this research as to develop an automated system to monitor microplankton respiration via analysis of ETS activity. This system would facilitate the processing of the large number of seawater samples that are characteristically taken on ocean survey cruises. Furthermore, it would permit the construction of maps of plankton metabolism. (Author) |
