The 50th Anniversary of the International Indian Ocean Expedition (IIOE-2)


The International Indian Ocean Expedition (IIOE) was one of the greatest international, interdisciplinary oceanographic research efforts. It involved forty-­six research vessels (under fourteen different flags) that carried out an unprecedented number of hydrographic surveys (and repeat surveys) of the entire Indian Ocean basin from 1960 – 1965.

In the 50 years since the IIOE, there have been two fundamental developments in ocean science. The first is the emergence of new components of the ocean observing system - most notably remote sensing and Argo floats. The second is the emergence of ocean modelling in all its facets - including short-­term forecasting, seasonal predictions and climate projections. These developments have revolutionised our understanding of the global oceans. Compared to the IIOE, we now have the capacity to provide a more integrated picture of the Indian Ocean, particularly if these technologies are combined with targeted and well-­coordinated in situ measurements.

A celebration of the 50th Anniversary of the IIOE is being organised by the Chairs of the GOOS/CLIVAR Indian Ocean Panel (IOP), the SIBER and IOGOOS programmes, and key representatives from the Indian Ocean rim countries and other international programmes. Relevant broader membership is encouraged.
