Indian Ocean IODP Workshop

An Indian Ocean IODP Workshop is to be held in Goa on 17-18 October, and planning is well underway. The workshop will be hosted by India, and is jointly planned by India and ANZIC. The conference organisers dealing with foreign scientists are Neville Exon of the Australian National University, Dhananjai Pandey of NCAOR, Goa, and Stephen Gallagher of Melbourne University. Many key participants have agreed they will come, but we are now asking other scientists with ideas potential Indian Ocean scientific ocean drilling to consider applying to attend. Numbers will be limited. The aim is to further develop existing proposals and start work on new proposals, which could be considered for drilling from late 2013, assuming that JOIDES Resolution will go into the Indian Ocean at the beginning of the next phase of IODP. The latest plans have the JOIDES Resolution program for the present phase of IODP ending in the Sea of Japan in late 2013

 Because there has been no scientific ocean drilling in the Indian Ocean for nearly a decade, this workshop is vital in building the international scientific alliances that can lead to further strong proposals. Also, India itself has only joined IODP recently and such a workshop will provide wide exposure of the Indian science community to IODP science and IODP capability, leading to better understanding and new IODP proposals. The following four themes have been arranged for the workshop and planning sub-committees have been formed:

1. Cenozoic oceanography, climate change, gateways and reef development.

This is designed to cover both broad questions related to the Indian Ocean, and more narrow ones such as the causes and effects of the Indonesian Throughflow current and of sea level rise and fall and the origin of late Pleistocene reefs. Sub-committee Chairman is Stephen Gallagher of Melbourne University (sjgallの後に

2. The history of the monsoons.

This will cover tectonics, uplift, weathering and erosion, sediment deposition, and climate and oceanography. It will deal with all Indian Ocean areas affected by monsoons. This will allow discussions/nurturing of proposals emerged since the Detailed Planning Group (DPG) workshop on monsoon in 2008. Sub-Committee Chairman is S. Rajan (rajanの後に

3. Tectonics and volcanism.

There are many questions related to the tectonism of the Indian Ocean, such as plate tectonics, the evolution of the oceanic crust including mid-ocean ridge formation, and the formation of large igneous provinces; continental rifting and related deposition; subduction, arc volcanism and earthquakes. Sub-committee chairman is Mike Coffin (Mike.Coffinの後に

4. The deep biosphere.

Pioneering studies of the “extremophiles” of the deep biosphere in sediments and basalts have largely been concentrated in the Atlantic and Pacific Oceans. Given the different nature of the oceanography and inputs of organic matter into the Indian Ocean, the deep biota could be rather different there. Sub-committee Chairman is Steve D’Hondt (dhondtの後に

Note that the 7th International Conference on Asian Marine Geology, which has an IODP session, is taking place in Goa in the previous week, should you wish to attend that meeting.

Should you be interested in attending the workshop there are three steps to take:

1) Examine the draft program as set out below
2) Contact the conference organisers with an expression of interest setting out briefly what you will bring to the workshop:

3) Contact your funding agencies for necessary support. American scientists, for example, have a proposal for funding for eight scientists with Ocean Leadership (Application by Steven Clemens Steven_Clemensの後に IODP-MI is supporting a number of key participants from member countries and much of its funding has been already allocated. ANZIC is supporting Australian and New Zealand participants.

02.30-04.30  Thematic breakout session

Key scientific hypotheses that can be tested by drilling the Indian Ocean
Members of scientific community will give short presentations (10 to 20 mins each plus 10 mins questions) on possible proposals/ideas to test key scientific hypotheses by drilling the Indian Ocean. This session will also be used to identify potential proposals that can be nurtured in a later breakout session.

It is anticipated that the majority of the potential participants in this part of the workshop will have previously submitted a short (100 word summary) of possible drilling prospects/ideas.? These will be considered by the committee for inclusion in this session.
