Notification May 18, 2016

To all participants in the International Workshop for Large-Scale Research Cruises of JAMSTEC 2014

Thank you very much for participating in the workshop for Large-Scale Research Cruises of JAMSTEC that was held in November 2014. Please accept our sincere apology for our long silence after the workshop. After the workshop, budget situation and ship availability of JAMSTEC have drastically changed, and it took long time to decide the final direction for implementing the Large-Scale Research Cruise of JAMSTEC.

However, the framework of the Large-Scale Cruise was finally fixed at the discussion of JAMSTEC's internal screening committee held on April 14 of this year, and we would like to inform you about the current status of the eight cruise proposals completed during the workshop.

  • We will implement a Large-Scale Research Cruise in the fiscal year 2018. R/V Mirai, one of our oceanographic research vessels, will be used for this purpose, because all other ships were already reserved for other tasks. Based on the current budget situation, the maximum length of the cruise may not exceed 100 days.
  • The committee agreed four cruise proposals to go to the next step (see below), because of their feasibility of cruise under the above-mentioned conditions.
  • We asked the leaders of the four proposals to select a candidate for the Principal Investigator (PI). Then we asked these PI candidates to revise and resubmit a new cruise proposal that fits to the above-mentioned conditions, under discussion with the co-proponents of each proposal.
  • JAMSTEC's internal screening committee will conduct the final round of screening on May 30, 2016 after reviewing the resubmitted proposals and make the final decision which proposal should be implemented.

The reports prepared by the participants two years ago were all interdisciplinary and showed exceptionally high scientific merit. Our selection was made very much in the light of the proposed research vessel and length of cruise. We will inform you again of our final decision on the proposal to be implemented, as soon as it has been made.

We ask for your continued understanding and cooperation.

Sincerely yours,

Yoshihisa Shirayama
Executive Director for Science
Japan Agency for Marine-Earth Science and Technology (JAMSTEC)
