Report on Primary Production Training CourseUniversity of Concepción, Chile
21 October - 1 November, 2002
by Dr. Trevor Platt
An advanced course on "Primary Production: Theory, Modelling and Estimation by Remote Sensing" was held from October 21 to 1 November, 2002 at the University of Concepción (UdeC), Chile. It was held under the auspices of IOC/UNESCO, the Chilean Ministry of Education (MECESUP), Minera Escondida, the DAAD, the UdeC's School of Graduate Studies and the Center for Oceanographic Research (COPAS), with additional funding from the International Ocean-Colour Coordinating Group (IOCCG) and from the Partnership for Observation of the Global Ocean (POGO) to facilitate participation by students from outside Chile. In all there were 26 students, of whom 8 were from Chile and 18 from elsewhere (7 other countries). See list of students attending the training course.
The additional funding from international committees also allowed the participation of more instructors than would otherwise have been the case. The list of instructors was: Dr. Trevor Platt (Bedford Institute of Oceanography, Canada); Dr. Shubha Sathyendranath, (Dalhousie University, Canada); Dr. Vivian Lutz (Instituto Nacional de Investigación y Desarrollo Pesquero, Argentina); Dr. Cesar Fuentes-Yaco (Bedford Institute of Oceanography, Canada); Dr. Mark Dowell (University of New Hampshire, USA); and Dr. Osvaldo Ulloa (University of Concepcion, Chile). In addition, Mr. Gabriel Yuras provided assistance in the practical demonstrations.

The course proceeded by lectures in the morning and by practical work in the computing laboratory in the afternoons. In addition students were encouraged to give short presentations on their own work, and most of them did so.
In the practical sessions, the students learned to use the software MATLAB, which is important in the image analysis field (and indeed in many other fields of science). Next, they learned to acquire and process ocean-colour data for regions of their interest. Then, they learned to apply MATLAB to the calculation of the submarine light field and of primary production. Finally, they processed an ocean-colour image from a region of their choice and used it to estimate primary production for the region concerned.
Many students took the course for credit, and an evaluation was therefore required. This took the form of a small research proposal. The students were required to state the objectives of the proposed research, the area of study, methods, and expected results. The context was an ocean-colour image that they had processed themselves and that they were required to interpret as part of the exercise. The proposal would illustrate an application of ocean-colour data according to the interests of the student.
The lectures covered the following material:
At the end of the course, the students were presented with a CD containing material from the course, including software, manuals and lecture notes in 30 chapters (some 234 pages). In addition, a website was established containing all this material and other logistic information relevant to the course. This website will continue to be available after the course is finished, for the benefit of the students. It will be protected by password and will include, for example, the projects submitted by them for the evaluation.
Various factors contributed to the undoubted success of this course. First was the selection of the participants: several really outstanding students were identified, and the average level of ability was very high. The extent of their motivation was most impressive. Second, the facilities provided by the university were excellent. A very fine computing laboratory, located adjacent to the lecture room, was provided for exclusive use every afternoon, and all day on weekends. This allowed the students to work individually or in pairs on their image analyses and facilitated practical demonstrations. Third, the magnificent support rendered by Mr. Gabriel Yuras ensured that the practical part of the course ran without difficulty.
Given all these favourable circumstances, the instructors were able to
achieve everything they had intended to do. The additional financial
support provided by the IOCCG and by POGO leveraged the Chilean funds to
the maximum and enabled students from outside Chile to attend, and
additional instructors to contribute, to the benefit of all concerned. The
contacts developed between students and instructors, and between the
students themselves, should be invaluable in the future. It is expected
that they will lead to development of a multilateral joint research
proposal in the subject area of the course.
