At the start of the new millennium, El Niño (EN) marine researchers are looking back at about twenty years of intense work. In these years there have been numerous symposia and workshops dealing with EN (and recently, also La Niña, LN) both in the areas of the Humboldt Current and the California Current, and knowledge on EN characteristics and impacts in each of these two large ecosystems has increased significantly. However, whereas scientists in the CPPS/ERFEN and CalCoFi context are cooperating very successfully, researchers from the Humboldt Current/California Current have only met on few occasions such as the RIBEN meetings. To date no serious attempt has been made to arrive at a comprehensive joint Eastern Boundary Current vision of the processes and effects involved during strong EN or extended LN periods, and of the overall role these processes play in the context of basin-scale climate changes. The Viña Symposium intends to strengthen research interactions between Humboldt Current and California Current scientists working on ENSO. Key note speakers have been invited to this Symposium to present "paired" talks that provide an integrated vision of EN/LN characteristics and impacts in the two current systems, elaborating upon their similarities and differences.

Fisheries research dealing with EN impacts has sometimes been confronted with the criticism that it is not sufficiently connected with the needs and problems of practical resource management. This problem should be tackled in a dialogue between fisheries researchers and managers, and guidelines might be developed to provide a perspective for more cooperative resource-directed fisheries science in the future. The idea is that experts will meet in the context of a workshop dealing with El Niño/La Niña and fisheries, as well as associated socio-economic problems.

This meeting has been planned within the context of the bilateral cooperation between Chile and Germany, represented by the Comisión Nacional de Investigación Científica y Tecnológica (CONICYT) and the International Bureau for North and South America of the German Ministry for Education and Research (BMBF), respectively. It is embedded in the framework of the Eastern Pacific Consortium for Research on Global Change, and is also supported by the Sociedad Chilena de Ciencias del Mar. Last but not least it is part of the celebrations of the 75th anniversary of the Universidad Católica de Valparaíso. The organisers are grateful to these organisations for their continued support.
