1997-1998 El Niņo Studies off the West Coast

Francisco Chavez

 Multivariate ENSO Index Comparison Graph


The 1997-98 El Niņo was one of  the strongest event of the century. The multivariate index is now tracking (as predicted) the development of the 1982-83 El Niņo. It will be debated which of these events will be considered stronger. Based on climatic repercussions along the coasts of Peru and California the 97-98 event has exceeded 82-83.

Acting on a request of the Research Advisory committee, a meeting was convened at MBARI on March 9, 1998 to discuss efforts to coordinate El Niņo research along the West Coast of North America.    Organizing a Scientific Workshop on 1997-98 El Niņo in 1999 was discussed.  Attending this meeting were: Tom Hayward (Scripps) ,Ken Smith (Scripps) , Francisco Chavez (MBARI), Curt Collins (NPS) ,Bob Smith (Oregon State),Jane Huyer (Oregon State), Dave Mackas (IOS, Canada), Frank Schwing (NMFS).

The Scientific Workshop took place at the Monterey Bay Aquarium Research Institute (MBARI) in early December 1999.  Abstracts from this meeting are available online.  An EOS note is being prepared for publication in addition to a special issue, scheduled for late 2000.

We have collated the research efforts on this web site, where one may view cruise schedules, hydrographic and mooring station maps, and links to project web pages.   We are currently working on an online atlas, which will be available in the summer 2000.
