IndOOS Decadal Review (2006 ~ 2016)

IndOOS-2: A Roadmap to Sustained Observations of the Indian Ocean for 2020-2030

To download the postcard


IndOOS is the sustainable ocean observation system for the Indian Ocean. The goal of IndOOS is to provide sustained high-quality oceanographic and marine meteorological measurements to support knowledge based decision making through improved scientific understanding, weather and climate forecasts, and environmental assessments. The current IndOOS design was established on the basis of the Implementation Plan drafted by the IORP in 2006.  Both Indian Ocean science priorities and measurement technologies have evolved since the original design was established. Also, we have learned some practical lessons in the implementation phase of IndOOS that can be usefully incorporated into recommendations for how to improve cost-effectiveness, operational efficiency and interdisciplinary synergies.  Finally, the Second International Indian Ocean Expeditions (IIOE-2, 2015-2020) was just kicked off, provide a unique opportunity for providing enhanced resources to IndOOS. 

The CLIVAR IORP co-chairs will hence lead the writing of a revised IndOOS implementation plan, with the help of a writing team comprised of selected IORP, SIBER, IO-GOOS members as well as invited experts. The writing team aims at providing a first draft by September, 2017. This draft will be open to scientific colleagues for comments and feedbacks, and will be formally reviewed by an ad hoc review board, independently nominated by the review sponsors, back to back with the next IORP face-to-face meeting in early 2018. This review of IndOOS is sponsored by CLIVAR (through IORP) , OOPCIMBeR (through its SIBER Indian Ocean project) and IO-GOOS.

IndOOS Mission Statement

The goal of IndOOS is to provide sustained high-quality oceanographic and marine meteorological measurements to support knowledge based decision-making through improved scientific understanding, weather and climate forecasts, and environmental assessments for the benefit of society.

Terms of Reference for IndOOS Review

1. Make actionable recommendations for priority observing system components going forward, including pilot studies with new technologies 
2. Provide justification for these recommendations by:
    a. Reviewing IndOOS current status and its past successes and failures;
    b. Articulating the scientific and operational drivers of IndOOS and their societal impacts; 
    c. Identifying the Essential Ocean Variables (EOVs) that address these drivers, their spatial coverage and temporal/spatial resolution.

Main activities

1. IndOOS Review Workshops

1.1 1st IndOOS Review Workshop (Jan. 30 - Feb. 1, 2017, Perth Australia)

The goals of the review workshop are:

• To learn the history of IndOOS, the successes and failures, and the big science achieved, so that we can identify issues and strategies related to designing and sustaining IndOOS.
• To get information and ideas about how to conduct a review, so that we can identify the best way to evaluate and evolve IndOOS
• To hear about important scientific advancements and broad-scale climate questions from across the Indian Ocean basin, so that we can identify the high impact science IndOOS will need to contribute to in the future.
• Finally, to frame the IndOOS review and identify steps forward to producing the white paper

1.2 2nd IndOOS Review Workshop (22-23, March 2018, Jakarta Indonesia)

The 2nd Indian Ocean Observing System (IndOOS) Review Workshop was organised on the 22-23 March 2018 in Jakarta, Indonesia. During the workshop, each of the chapter of the review will be presented orally to the review board, and the overall recommendations are expected to be agreed on.

1.3 3rd IndOOS Review Workshop (14 March 2019, Port Elizabeth, South Africa)

The thrid Indian Ocean Observing System (IndOOS Review Workshop was organised on 14 March 2019 in Port Elizabeth, South Africa. During this workshop, the final actionable recommendations have been communicated to science community and stakeholders, Constructive implmentation strategy for IndOOS has been discussed and agreed during the workshop.
