The Second International Indian Ocean Expedition (IIOE-2) is a major new program under the auspices of UNESCO IOC, Indian Ocean Global Ocean Observing System (IOGOOS) and Scientific Committee on Oceanic Research (SCOR).
The five year IIOE-2 program (2015 - 2020) seeks to address the ongoing pattern of under sampling in the Indian Ocean through a renewed collaborative international research effort, a push to fully develop the Indian Ocean Global Ocean Observing System (IndOOS) and to transfer the outcomes of this new understanding to all nations. It follows on fifty years after the first International Indian Ocean Expedition (IIOE), which occurred between 1959-65 as the first international collaborative program of scientific cruises and observations undertaken at such a grand scale in the Indian Ocean. The baseline scientific information gathered under IIOE is still of significant societal and environmental relevance today.
IIOE-2 was officially launched in Goa, India on 4 December 2015. The launch represented the culmination of over 4 years of international planning work for which the IOC PPO led the IOC’s engagement. The IOC PPO on behalf of the IOC helped to develop an IIOE-2 Science Plan and an IIOE-2 Implementation Strategy as the two principle guiding frameworks for the program.
Since the launch, the IOC PPO has been designated as one of two Joint Project Offices (JPO) for IIOE-2, the other located in India (INCOIS, Hyderabad). The JPO’s are charged with working together to help oversee the successful implementation of IIOE-2 on behalf of the program’s co-sponsors and through assisting the IIOE-2 Steering Committee. The Head of the IOC PPO also has the added responsibility of being the IOC’s IIOE-2 Coordinator and therefore has a leading role in all aspects of the IOC’s engagement in and leadership of IIOE-2. Principally this involves providing Secretariat support to the IIOE-2 Steering Committee and associated IIOE-2 Science Theme and Working Group teams, as well as facilitating resourcing, sponsorship and outreach/communication. This responsibility is an important component of the IOC PPO’s overall international collaborative work program and aligns closely with the IOC PPO’s role in supporting IOGOOS.
The IIOE-2 has its own dedicated IIOE-2 website containing extensive documentation on the governance and implementation arrangements for IIOE-2, along with up to date information on research activities and proposed collaborative projects. We encourage you to visit the IIOE-2 website for up to date information.

Context to IIOE-2
|“to advance our understanding of the Indian Ocean and its role in the Earth System in order to enable informed decisions in support of sustainable development and the well-being of humankind.”|
IIOE-2 research activities will collect new data and undertake process studies on a range of physical, biogeochemical, biological and coupled climatic characteristics of the Indian Ocean from coastal environments out to the deep sea. Focused research on the Indian Ocean has a number of benefits for all nations. The Indian Ocean is complex and drives critical aspects of the region’s climate including extreme events (e.g. monsoons, droughts, waves and storm surges). It is the source of important socio-economic resources (e.g. fisheries, oil and gas exploration/extraction, eco-tourism) and is the background and focus of many of the region’s human populations around its margins. In this context, IIOE-2 research will be guided by the following six science themes as detailed in the IIOE-2 Science Plan:
1. Human impacts;
2. Boundary current dynamics, upwelling variability and ecosystem impacts;
3. Monsoon variability and ecosystem response;
4. Circulation, climate variability and change;
5. Extreme events and their impacts on ecosystems and human populations; and
6. Unique geological, physical, biogeochemical and ecological features of the Indian Ocean.
Research and observations supported through IIOE-2 will result in an improved understanding of the ocean’s physical and biological oceanography, and related air-ocean climate interactions (both in the short-term and long-term). The IIOE-2’s program will complement and harmonise with other regional programs underway and collectively the outcomes of IIOE-2 will be of huge benefit to individual and regional sustainable development as the new information will be a critical component of improved decision making in areas such as maritime services and safety, environmental management, climate monitoring and prediction, food and energy security. In this context, the collaborative oceanographic and atmospheric research undertaken during IIOE-2 will be fundamental for future sustainable development and expansion of the Indian Ocean’s blue economy.
IIOE-2 activities will also include a significant focus on building the capacity of all nations around the Indian Ocean to understand and apply observational data or research outputs for their own socio-economic requirements and decisions. IIOE-2 capacity building programs will therefore be focused on the translation of the science and information outputs for societal benefit and training of relevant individuals from surrounding nations in these areas.
The program is being overseen by a Steering Committee (SC) of voluntary stakeholders that collectively set the high-level policies for IIOE-2 and take responsibility for the delivery of the project over the 2015-2020 period.
The IIOE-2 Steering Committee structure is organised as follows:
Co-Chairs (IOGOOS, SCOR, UNESCO IOC)
Joint Project Office
Leading personnel represented on Steering Committee as x-officio
Strategic Executive Level
One representative (leader) per each of the six science themes from the SCOR SPDC IIOE-2 Science Plan
One representative (leader) per each of the seven operational divisions
One representative per each major IOC regional body/committee
Regional Coordination Level
One representative per each IIOE-2 ‘national committee’
Science Delivery Level
One representative (i.e. Principal Investigator) per each ‘major’ IIOE-2 scientific research initiative, including a representative of the Early Career Scientists Network from the Capacity Development Working Group
Most members of the Steering Committee are in place and working with their respective stakeholder groups to implement IIOE-2. For a full list of members please refer to the IIOE-2 website.
IIOE-2 is co-sponsored by IOC, IOGOOS and SCOR:
