This international program of discovery will be guided by a rich set of contemporary science questions. It will provide new observational data that will be processed, curated, managed and used to underpin characterisation of key oceanic and related atmospheric processes at a wide spectrum of spatial and temporal scales. This will support improved modelling and predictability, and as an integrated body of new information, the transfer of knowledge for societal benefit with an emphasis on capacity development as a key vehicle to achieve this objective URL: http://www.iioe-2.incois.gov.in/

The RV Dr Fridtjof Nansen in the Western Indian Ocean: voyages of marine research and capacity development. [1975-2016]Marine scientists and oceanographers from many countries have cooperated on research in the Indian Ocean since the end of the 1950s. This collaboration stemmed from the International Indian Ocean Expedition (IIOE), which evolved into a major international venture, attracting roughly 40 research vessels from 20 countries, between 1959 and 1965. Partly as a consequence of this outcome, the second session of the FAO Committee on Fisheries (COFI), in 1968, recommended the establishment of an Indian Ocean Fishery Commission (IOFC). Experience gained from the first Norwegian fisheries cooperation with the Indian State of Kerala (1952– 1972) highlighted the need – and importance – of research and trial fishing in development cooperation in fisheries. This was an area in which Norway had expertise that could be shared. In 1970 Norad offered to build a research vessel for use by the FAO Fisheries Department, with operational costs to be shared between the two parties. The research vessel (RV) Dr Fridtjof Nansen was then built, and began operations in 1975. Nine of its first ten years (1975–1984) were spent in the Indian Ocean.

IIOE-2 Cruise No.EP1-1, 4 December, 2015 - 22 December 2015, Goa, India - Mauritius. ORV Sagar Nidhi Cruise 105 (04 – 22 December 2015) International Indian Ocean Expedition - 2, First Expedition.SN-105 is the first cruise conducted as a part of the Second International Indian Ocean Expedition (IIOE-2). IIOE-2 was launched as well as SN-105 was flagged off at Goa by the Minister of State for Science and Technology, Govt. of India on 4 December 2015. The major objective of this multidisciplinary observational expedition is to understand the structure of water masses in the western Indian Ocean along 67E and possibly assess the difference in their characteristics with respect to the measurements made during IIOE. The other objective of the cruise is to understand the physical-chemical-biological characteristics in the equatorial Indian Ocean and their interrelationships. The major observational objectives are to map the hydrography in the upper 1000m where the Red Sea, Persian Gulf and Arabian Sea High Salinity water are known to be present, collect water samples to determine chemical, biological and optical parameters.

IIOE-2 Cruise No.EP12-1, 15 April, 2017 - 03 May, 2017 Kochi, India - Goa, India. Dust induced Primary Productivity and N2 fixation experiments in the Arabian Sea.Oceans act as a major sink for anthropogenic CO2 through primary production. The Arabian Sea (area ~6.2 × 106 km2) covers only about 1% of the global ocean surface but contributes up to 5% of the global marine primary production, partly due to high influx of ‘new’ nitrogen via diazotrophic N2 fixation. Iron, whose main source in the ocean is atmospheric transport of dust, is an essential nutrient for sustaining N2 fixation. Despite being in the vicinity of the Thar desert on the east and the Arabia desert on the west, the Arabian Sea has been projected to be an HNLC (high nutrient low chlorophyll) region

Launch of the International Indian Ocean Expedition-2.POGO NewsletterBeginning in late 2015 and continuing through to 2020, the Second International Indian Ocean Expedition (IIOE-2) is a major global scientific initiative that seeks to build on the legacy of the first and one of the greatest oceanographic expeditions of all time, the IIOE (1957-65). The overarching goals of this ambitious international endeavour are to advance our understanding of the interactions between geological, ocean, and atmospheric processes that give rise to the complex physical dynamics of the Indian Ocean region and to determine how those dynamics affect the climate, extreme events, ecosystems, and human populations.

New era for Indian Ocean research: news article on WAMSI website.Western Australia Marine Science Institution (WAMSI), 2016The disappearance of flight MH370, the devastation caused by the 2004 Boxing Day Tsunami, the profound societal impact of monsoons which are so strongly linked to the Indian Ocean and the fact that so many island groups, states and territories rely on its little understood ways has helped to renew a global drive to find out more about the only ocean to be blocked by land to the north. Indian Ocean research came into focus in Goa, India, recently when researchers from around the world presented their findings ahead of a Second International Indian Ocean Expedition (IIOE2), launched 50 years after its predecessor. A group of researchers from WAMSI partner organisations (CSIRO; Murdoch University, Curtin University, The University of Western Australia, Bureau of Meteorology and IMOS) attended the ‘Dynamics of the Indian Ocean: Perspective and Retrospective’.
