“…The two most recent JOIDES Resolution expeditions attempting to core deep holes into oceanic crust were Integrated Ocean Drilling Program Expedition 335, Superfast Spreading Rate Crust 4 (13 April-3 June 2011; Teagle, Ildefonse, Blum, and the Expedition 335 Scientists, 2012;see Expedition 335 Scientists [2012] for a detailed operational assessment), and International Ocean Discovery Program (IODP) Expedition 360, Southwest Indian Ridge Lower Crust and Moho (30 November 2015-30 January 2016MacLeod, Dick, Blum, and the Expedition 360 Scientists, 2017; see Dick et al [2016] for a detailed operational assessment). In May 2017, outcomes from these two expeditions motivated the JOIDES Resolution Facility Board (JRFB) to recommend that a Deep Crustal Drilling Engineering workshop be held (JOIDES Resolution Facility Board, 2017).…”

Expedition 384 is scheduled to begin in Kristiansand, Norway, on 20 July 2020 and end in Las Palmas, Spain, on 5 September and is dedicated to engineering testing as it relates to deep (>1 km) drilling and coring in igneous ocean crust. The Deep Crustal Drilling Engineering Working Group convened in 2017 to discuss recent issues with crustal drilling and recommended a number of technologies and tools for potential testing. The JOIDES Resolution Facility Board further prioritized the testing opportunities in 2018. The top priority of all recommendations was an evaluation of drilling and coring bits because coring bit wear, tear, and failure is the prevalent issue in deep crustal drilling attempts, requiring an excessive amount of fishing and hole cleaning time. The primary objective of Expedition 384 is to drill "pilot holes" using three types of drill bits: two tungsten carbide insert (TCI) tricone bits, a polycrystalline diamond compact (PDC) bit, and a TCI/PDC hybrid bit. Additional tests include the deployment of an underreamer as well as a PDC coring bit to obtain samples for engineering testing. The results may lead to an initiative toward developing a better performing coring bit for future use by the International Ocean Discovery Program (IODP).The site location for these tests has evolved with the multiple postponements of Expedition 384 for various reasons. The current primary site is Proposed Site REYK-13A (1520 m water depth) from postponed IODP Expedition 395; this site has ~210 m of recent to Pliocene clay or ooze overlaying basaltic basement that has not been drilled or cored to date. The plan is to drill 6 holes to ~100 m into the basement each. A second site was selected for operations should time and equipment remain to do so: Integrated Ocean Drilling Program Site U1309 (1653 m water depth), where basaltic and gabbroic rocks are exposed at the seafloor, has been cored to 102 m in Hole U1309B and 1415 m in Hole U1309D. The plan is drill one hole to ~200 m. Operations at Sites REYK-13A and U1309 are projected to take 22.4 days.Additional operating time became available for Expedition 384 as a result of the latest schedule changes. A secondary objective therefore includes the assessment and potential improvement of current procedures for advanced piston corer (APC) core orientation. A total of 4.6 days is allocated to triple-coring the top 70 m of sediment at Proposed Site REYK-6A (postponed Expedition 395), located 54 nm east of Proposed Site REYK-13A. Schedule for Expedition 384Expedition 384 is an engineering testing opportunity based on community requests, primarily those formulated in the Deep Crustal Drilling Engineering Working Group report (DCDEWG, 2017) and additional JOIDES Resolution Facility Board (JRFB) advice (JRFB, 2018). At the time of publication of this Scientific Prospectus, the expedition is scheduled to start in Kristiansand, Norway, on 20 July 2020 and to end in Las Palmas, Spain on 5 September. The plan currently calls for ~47 days of operations: ~2 days in port, ~18 days i...

“…洋壳在大洋中脊产生, 但是大洋中脊的扩张速率快慢不一, 快速的如太平洋每年 10~20 cm, 大西洋每年 2~4 cm, 而超慢速的西南印度洋每年扩张不足 2 cm, 那里的莫霍面不见得就是地壳和地幔的分界, 也有可能是地幔岩蛇纹岩化的下界. 因此, 大洋钻探一方面积极筹备, 在东太平洋选择洋壳最薄的地方实施原来意义上的莫霍钻; 另一方面又设立了"慢速莫霍计划(SloMo)", 探索西南印度洋的另类"莫霍面" [11] . [16] .…”
