IODP 871-CPP: Lord Howe Rise Deep Stratigraphic Drilling

Report on Proposal Development Workshop
Tokyo, Japan, 25–28 August 2015
Background
Deep stratigraphic drilling on the Lord Howe Rise has been under discussion between Geoscience Australia(GA) and the Japan Agency for Marine Earth Science and Technology (JAMSTEC) since 2006. A significant
step towards realising this deep drilling program was made with the submission of a pre-proposal to theInternational Ocean Discovery Program (IODP) on 1 October 2014. This pre-proposal was positively
reviewed by the IODP Science Evaluation Panel (SEP) and recommended for development into a fullproposal. The SEP suggested some areas to be addressed in more detail in developing the full proposal:

Better define testable hypotheses that can be addressed by drilling;
Strengthen links to IODP proposal 832 (drilling of post-Cretaceous sediments on and around theLord Howe Rise); andInclude a plan for drilling.

The Chikyu IODP Board (CIB) subsequently endorsed the SEP review and agreed to provide funds to support
a workshop in Japan to further develop the full proposal.
In addition, an initial Science Workshop was held 8–9 April 2015 in Sydney, Australia. This workshop
attracted about 40 participants who reviewed the pre-proposal and commenced planning for the fullproposal. The workshop established three themes for the full proposal (Earth, Oceans/climate and Life) anddebated the relative global importance of these themes. In order to address the SEP review comments,discussion also focussed on the key scientific questions and hypotheses.
Following the Science Workshop, an initial draft of the full proposal was circulated to the proponents inearly August 2015. This draft was revised throughout August 2015 and formed the basis for discussions atthe CIB-funded Proposal Development Workshop held 25–28 August 2015 in Tokyo.

Purpose of Symposium and Workshop
Two events to progress the IODP proposal for deep stratigraphic drilling on the Lord Howe Rise took place
at JAMSTEC Headquarters in Tokyo (see Attachment 1 for Program):
1. 25 August 2015: A symposium to engage with and encourage further involvement from theJapanese scientific community; and2. 26–28 August 2015: A workshop to finalise a draft of the full proposal in preparation for submission
to IODP by 1 October 2015. The CIB provided funds (~US$30K) that allowed the coordinators ofeach proposal theme (Earth, Oceans/Climate and Life) and several other key proponents fromoutside Japan to participate in the workshop.

Outcomes
Symposium
The pre-workshop symposium was attended by 69 scientists from JAMSTEC and other Japanese institutions(see Attachment 2). For most of these scientists, the symposium was their first exposure to the project.
Several symposium attendees remained for the workshop and others committed to future involvement inthe project.
Dr Andrew Heap, Geoscience Australia, presented an overview of the LHR IODP project as a lead-in toseparate presentations, in Japanese, on each of the themes of the proposal:Earth, Dr Yasuhiro Yamada (JAMSTEC)
Oceans/Climate, Dr Jun’ichiro Kuroda (JAMSTEC)
Life, Dr Fumio Inagaki (JAMSTEC)Dr Suiichi Kodaira (JAMSTEC) also presented an overview of the deep-crustal and site surveys that areplanned prior to drilling.

Workshop
Eighteen scientists from Japan, Australia, the United Kingdom and the United States participated for the full
duration of the workshop (Attachment 3). Several other scientists and technicians contributed specificinput at various times (e.g. on planning for site surveys and drilling).
By the end of the workshop, a near-final draft of the full proposal was completed. This draft was refined
following the workshop and circulated to all proponents for feedback and further input three weeks prior
to the IODP submission deadline.
The revised objectives for each theme, as agreed at the workshop, were:

Earth: To define the role and importance of elongate strips of continental crustal ribbons in platetectonic cycles and continental evolution.
Oceans/Climate: To recover new high-latitude data to better constrain the timing and nature of
Cretaceous paleoclimate and linked changes in ocean biogeochemistry.
Life: To test fundamental evolutionary concepts of sub-seafloor microbial life over a 100 million
year timeframe.

Each of these objectives will be addressed by testing a number of hypotheses that were finalised during theworkshop and included in the draft full proposal.
The full proposal, entitled “First deep stratigraphic record for the Cretaceous eastern Gondwana margin:Tectonics, paleoclimate and deep life on the Lord Howe Rise high-latitude continental ribbon”, wassubmitted to IODP on 1 October 2015. The submitted full proposal includes 38 proponents from 20
different institutions in 7 different countries.

Other outcomes
The workshop also provided the opportunity to progress other aspects of the LHR IODP project. Theseincluded:


Determining a preliminary drilling plan for inclusion in the IODP proposal with JAMSTEC’s Centre for
Deep-Earth Exploration (CDEX, responsible for Chikyu drilling operations).
Planning for a pre-drilling deep-crustal geophysics and site survey (March–May 2016).

Benefits
A strong and ultimately successful IODP proposal that garners broad support from the international science
community is an important step in realising the goal to obtain deep Cretaceous rock samples from the SW
Pacific, arguably one of the last remaining geoscience frontiers on Earth. In this context, the CIB-supported
LHR IODP Symposium and Proposal Development Workshop was a success. The workshop facilitatedinteraction between a diverse team of Earth, ocean, climate and life scientists. This interaction led to thepreparation of a strong proposal to IODP. As an added benefit, the workshop generated additionalawareness of and interest in deep stratigraphic drilling on the Lord Howe Rise.
