Much has been achieved in 50 years of DSDP, ODP and IODP. However, to date deep riser drilling has played a relatively small role in IODP and its predecessors, albeit a role with considerable impact, especially in the understanding of subduction zone processes gained from CHIKYU drilling into the Japan forearc. More frequent deep riser scientific drilling is arguably a goal for the next 50 years of IODP. Geoscience Australia and JAMSTEC first discussed CHIKYU riser drilling on the remote Lord Howe Rise (LHR) continental ribbon, east of Australia, a decade ago. The resulting decade-long collaboration recognised the importance of the LHR in addressing globally-relevant scientific questions in Cretaceous tectonics and paleoclimate, as well as the limits to life on Earth. A proposal for deep riser drilling on the LHR was approved by IODP in early 2017. Subsequent planning for this ambitious expedition exemplifies the unique challenges faced by scientific riser drilling under IODP. These challenges include a need for comprehensive site surveys that allow a thorough assessment of geohazards, collection of baseline data to support environmental permitting, planning logistical support for remote, long-duration drilling operations, and securing funding for a high-cost expedition. This presentation will provide an overview of the efforts by JAMSTEC, Geoscience Australia and a diverse team of international proponents in delivering new data from the LHR extended continental ribbon that ultimately place IODP on the verge of ground-breaking scientific riser drilling in a remote part of northern Zealandia. Abstract submitted and presented at the 2018 Australian Geoscience Council Convention (AGCC) (https://www.agcc.org.au/)
