Steering Committee

IO 2021 committee

Introducing the US IIOE-2 Steering Committee

The launch of the Second International Indian Ocean Expedition (IIOE-2) has precipitated a renewed and growing interest in carrying out research in the Indian Ocean over the next 5 years and beyond. Many countries-including Australia, China, Germany, India, Indonesia, Japan, Norway, the United Kingdom, and the United States-are planning cruises and other activities in this time frame, and new regional research programs in the Indian Ocean are under development (Hood et al., 2016).

Because the funding for IIOE-2 research and societal applications is being generated within each participating country, the preferred model is for each country to have an IIOE-2 national committee with a chairperson who is the point of contact for the IIOE-2 Steering Committee and the IPO framework (IPC, 2015). National IIOE-2 committees have been established in India, Australia, Germany and the UK.A U.S. IIOE-2 Steering Committee was formed (fall 2015) in the United States to serve as a coordinating and implementing body for the U.S. contribution to the IIOE-2. This committee is composed of a highly interdisciplinary group of US scientists, all of whom have a strong interest in the Indian Ocean. The committee meets quarterly (via teleconference) and met in person at the 2016 Ocean Sciences Meeting in New Orleans.

The terms of reference for this committee establish the following goals:

  • Write a U.S. IIOE-2 Science Plan and Implementation Strategy based on the workshop.
  • Coordinate ongoing U.S. research in the Indian Ocean region and coordinate planning of new research.
  • Provide a forum for U.S. interagency discussions of Indian Ocean research and a liaison between the scientific community and these agencies.
  • Communicate U.S. research in the Indian Ocean region to national and international audiences through a Web site, newsletters, articles in the peer-reviewed and other literature, Twitter, and other approaches.
  • Represent the U.S. community on the international IIOE-2 Steering Committee.
  • Represent the U.S. community in international IIOE-2 meetings and discussions.
  • Liaise with U.S. SCOR and IOC committees.
Most of the committee’s initial activity has been aimed at convening town hall meetings and a workshop to inform the U.S. scientific community (including researchers and program managers) about the IIOE-2 and gather information to create a U.S. IIOE-2 research plan. Proposals to obtain financial support for the latter have been submitted and funded. The workshop was convened on September 11-13, 2017 at Scripps Institution of Oceanography. In addition, the committee has created a website (previously hosted by SCOR), it has been working to compile information on planned and proposed US-funded research in the Indian Ocean over the next 5 years and beyond, and it has developed a newsletter, the first issue of which came out in December 2016.
