Since then, my main responsibilities have expanded to include data analysis, web site design and maintenance, and the maintenance (hardware and software) of a direct broadcast receiving station. Details of these projects are given below. Previous experience My experience with optics and programming began almost twenty years ago when I was hired to assist an atmospheric scientist during the summers of my undergraduate degree. I spent three summers with this atmospheric team, where I learned the rudiments of data analysis, programming, instrument maintenance and calibration. In 1992 I completed my undergraduate degree: a B.Sc.Hons. in physics with first class honors, from the University of Canterbury in New Zealand. The following year I accepted a scholarship to undertake a Masters degree in oceanography, focused on ocean optics, at Dalhousie University in Canada, with Dr. Shubha Sathyendranath. During the course of this degree I gained further experience in data collection, instrument calibration, data analysis and programming. My thesis, "The Influence of Raman Scattering by Seawater and Fluorescence by Phytoplankton on Ocean Colour", involved theoretical modeling of the underwater light field as well as results from an experimental study. Two papers were published from this study. After completion of my masters degree in 1996, I was employed as a Research Assistant by Dr. John Cullen at Dalhousie University. During the year that I worked with his team, I collaborated closely with Richard Davis, helping with the analysis and processing of optical data. One of my responsibilities during this employment included the running, maintenance, and regular calibration of an irradiance instrument. By comparing the data I collected with a clear-sky irradiance model, I calculated the spectral effect that clouds have on downwelling irradiance. A paper describing the results from this study has been published. A further responsibility of mine included the processing of various types of optical data from oceanic measurements

3 MODIS experience Documentation of the NASA MODIS oceans code involved collaboration with the code programmers at the University of Miami, Florida, extensive study of the code, and planning of the documentation. Because of the large amount of documentation required, I initially decided to place it on the web, thereby making it easier for users to locate desired information. To achieve this goal, I familiarized myself with HTML and several programs available for the creation of web documents. Later I made the same document available in PDF form. I was solely responsible for updating the documentation as changes to the code were made, and also for providing the Japanese (and other interested parties) with current versions of the code. In early 2004 NASA implemented new MODIS processing code, so this documentation is now outdated. However, this project sparked my interest in website development and design. In late 2000 we acquired a satellite dish that enables us to receive data directly from MODIS as it passes overhead. I am responsible for installing, maintaining, and writing supporting scripts for the MODIS oceans code on our system, as well as helping to maintain and calibrate the satellite dish, and providing the data online in real-time by developing a database-based website: For this project, I work in close collaboration with Curt Vandetta, our computer systems manager. Web site design After designing and producing the web site for the MODIS oceans code documentation, I was asked to develop more web sites to make our optical data available to the scientific community. To ensure that the sites would be user-friendly and appealing, I studied a number of web site design books and online resources. The sites I create are continually updated with new data and information. New sites are also regularly added when new data sets become available. A list of sites that I designed and maintained follows below. Group website: Real-time Satellite Images website (aimed at the general public): MODIS direct broadcast station website: Recent satellite images over Hawaii/Chile/Alaska websites (for cruise support):

4 Optical data processing and analysis I am also responsible for the processing and analysis of optical data collected by a large number of in-situ oceanographic instruments. These instruments have included hand-deployed optical sensors both lowered into the water and allowed to sit at the sea surface, sensors attached to moorings, and sensors that drift with the ocean currents. I am responsible for processing these data as soon as they are collected, and making them available (with documentation) to interested colleagues. The analysis of these data includes the derivation of biological parameters from the optical data, as well as comparison of the data with each other and with data from other sources (such as ocean color satellite data), where applicable. I have made these data available, with documentation, to the scientific community on the web ( In January 1998, we were awarded a grant to provide processed optical data in a timely manner from measurements made monthly off the coast of Hawaii. As part of this study, I was given the opportunity to assist in the deployment of the instrument (a Profiling Reflectance Radiometer) during a research cruise. To ensure consistent deployments, I documented the deployment and instrument maintenance procedure for our colleagues in Hawaii. Upon receipt of the data from these deployments, it is my responsibility to process the data and format the data files for submission to the SeaWiFS Bio-Optical Archive and Storage System (SEABASS) of NASA. I have also provided documentation of these data and the instrument deployment procedure on the web, as well as access to the data for interested scientists. I was also involved with finding a solution to an optical problem that resulted from one of the optical data sets. Data are available from a sensor that was attached to a mooring that fluctuated with depth. The challenge was to determine a method to retrieve the characteristics of the water column from these measurements. To the best of my knowledge, this type of retrieval has not been undertaken before. I developed a semi-empirical model, based on equations describing oceanic optics, to perform this retrieval. This model was first presented at the Ocean Optics XIV conference in November In collaboration with Drs. Mark Abbott, Ricardo Letelier, and Scott Pegau, a manuscript describing the model and its accuracy has been published. Publications Abbott, M.R., R.M. Letelier, S. Laney, and J.S.
