  • Data report: high-resolution digital imaging of whole-round hard rocks collected during IODP Expeditions 390C, 395E, 390, and 393, South Atlantic Transect, using a DMT CoreScan3
Title: Data report: high-resolution digital imaging of whole-round hard rocks collected during IODP Expeditions 390C, 395E, 390, and 393, South Atlantic Transect, using a DMT CoreScan3
Hard rock cores recovered during International Ocean Discovery Program South Atlantic Transect (SAT) Expeditions 390C, 395E, 390, and 393 were digitally imaged using a DMT CoreScan3 line scanner aboard the R/V JOIDES Resolution during Expeditions 390 and 393. Methods outlined here involve modification of the CoreScan3 to scan >1 m long sections of hard rock at a 40 pixel/mm resolution, four times higher resolution than previously achieved during an ocean drilling campaign. This method is combined with a dedicated Python package (StitchIT) written to compile multiple 20 cm frames into high-resolution core section images. Accompanying this report are all compiled high-resolution section images from the SAT, both as high-resolution individual images of each section and as moderate-resolution visual core description–style images. The methods outline best practices for digitally imaging external core surfaces, and the data set is the first to be generated specifically for emerging machine learning and computer vision applications.  more » « less

    The South Atlantic Transect (SAT) is a multidisciplinary scientific ocean drilling project that will recover complete sedimentary sections and the upper ~250 m of the underlying oceanic crust along a slow/intermediate spreading rate Mid-Atlantic Ridge crustal flow line at ~31°S. These cores were originally scheduled to be collected during International Ocean Discovery Program (IODP) Expeditions 390 and 393 in October–December 2020 and April–June 2021, respectively. In 2020 and 2021, the global COVID-19 pandemic resulted in the postponement of several IODP expeditions, including Expeditions 390 and 393, chiefly because science parties were unable to travel to the R/V JOIDES Resolution. In response, the ship was used to conduct preparatory work for the postponed expeditions that did not require a science party aboard but could be carried out by the ship’s crew and a team of technicians from the JOIDES Resolution Science Operator. Two of these expeditions (390C and 395E) were in service of the SAT drilling project, to reduce the operational risks and expedite basement drilling during the rescheduled Expeditions 390 and 393. Expeditions 390C and 395E visited five of the six primary SAT sites and successfully cored a single advanced piston corer/extended core barrel hole penetrating the entire sediment section and <10 m into the underlying basalt before installing a reentry system in a second hole at each site visited. Given these accomplishments, the operations plans for the rescheduled Expeditions 390 and 393 have been revised.

    This report presents portable X-ray fluorescence (pXRF) geochemistry for lavas with mid-ocean-ridge to ocean-island basalt–like compositions recovered from the western flank of the Mid-Atlantic Ridge across the South Atlantic Transect (SAT) during International Ocean Discovery Program (IODP) Expeditions 390C, 395E, 390, and 393. The Bruker Tracer 5 pXRF spectrometer proved an effective tool for rapid, high downhole resolution determination of select major, minor (K, Ca, Ti, Mn, and Fe), and trace (V, Cr, Ni, Cu, Zn, Rb, Sr, Y, and Zr) elements on split core surfaces. Initial shipboard calibrations reported in the Expedition 390/393 Proceedings are improved upon and superseded here with an element-by-element refinement of secondary calibration curves and a thorough assessment of instrument drift and matrix effects between rock powders and sawed surfaces. Matrix corrections for Zr, Ti, and Y were necessary to align the pXRF data with shipboard inductively coupled plasma–atomic emission spectroscopy (ICP-AES) results for one of the pXRF analytical campaigns. Additional Zr drift corrections further improved the Expedition 390 data compared to shipboard ICP-AES. Replicate analyses of rock surface standards demonstrate precision of ≤11% RSD (relative standard deviation) for most analytes, with poorer precision only for V and Rb (≤25% RSD). Although less precise than ICP methods, demonstrable accuracy, differentiation of background and alteration halo analyses, and typical downcore spacing of 0.5–1 m make these data sets a useful tool for addressing SAT objectives related to volcanostratigraphy and hydrothermal exchange.

    International Ocean Discovery Program (IODP) Expedition 390C was implemented in response to the global COVID-19 pandemic and occupied sites proposed for the postponed Expeditions 390 and 393. The objectives for Expedition 390C were to core one hole at each site with the advanced piston corer/extended core barrel (APC/XCB) system to basement for gas safety monitoring and to install a reentry system with casing through the sediment to between ~5 m above basement and <5 m into basement in a second hole. These operations will expedite basement drilling during the rescheduled South Atlantic Transect Expeditions 390 and 393. The six primary sites for those expeditions form a transect perpendicular to the Mid-Atlantic Ridge on the South American plate, overlying crust ranging in age from 7 to 61 Ma. Basement coring will increase our understanding of how crustal alteration progresses over time across the flanks of a slow/intermediate spreading ridge and how microorganisms survive in deep subsurface environments. Sediment will be used in paleoceanographic and microbiological studies. Expedition 390C started in Kristiansand, Norway, and ended in Cape Town, South Africa, after 31 days of operations. We cored a single APC/XCB sediment hole to the contact with hard rock material at four of the six sites and successfully installed reentry systems with casing at three. Two failed attempts at drilling in casing and a reentry system into hard rock at Site U1558 indicate that the Dril-Quip reentry cones and running tools are incompatible with use in hard rock because the release mechanism does not work when the casing string weight cannot be fully removed from the running tool. Therefore, at Sites U1558 and U1559, casing was installed to ~10 m above basement. Site U1557 has a thick sediment cover (564 m) and will require multiple casing strings to reach basement; a single 16" casing string was installed to 60 meters below seafloor at this site, and later expeditions will extend casing.

    The South Atlantic Transect (SAT) is a multidisciplinary scientific ocean drilling project that comprises four International Ocean Discovery Program (IODP) expeditions: engineering Expeditions 390C and 395E as well as Expeditions 390 and 393. Altogether, the expeditions aim to recover complete sedimentary sections and the upper 100–350 m of the underlying oceanic crust along a slow/intermediate spreading rate Mid-Atlantic Ridge crustal flow line at ~31°S. The sediments along this transect were originally spot cored more than 50 y ago during Deep Sea Drilling Project Leg 3 (December 1968–January 1969) to help verify the theories of seafloor spreading and plate tectonics. Given dramatic advances in drilling technology and analytical capabilities since Leg 3, many high-priority scientific objectives can be addressed by revisiting the transect. The SAT expeditions target six primary sites on 7, 15, 31, 49, and 61 Ma ocean crust, which fill critical gaps in our sampling of intact in situ ocean crust with regards to crustal age, spreading rate, and sediment thickness. Drilling these sites is required to investigate the history of the low-temperature hydrothermal interactions between the aging ocean crust and the evolving South Atlantic Ocean and quantify past hydrothermal contributions to global biogeochemical cycles. Samples from the transect of the previously unexplored sediment- and basalt-hosted deep biosphere beneath the South Atlantic Gyre are essential to refining global biomass estimates and examining microbial ecosystems’ responses to variable conditions in a low-energy gyre and aging ocean crust. The transect is located near World Ocean Circulation Experiment Line A10, providing access to records of carbonate chemistry and deepwater mass properties across the western South Atlantic through key Cenozoic intervals of elevated atmospheric CO2 and rapid climate change. Reconstruction of the history of the deep western boundary current and deepwater formation in the Atlantic basins will yield crucial data to test hypotheses regarding the role of evolving thermohaline circulation patterns in climate change and the effects of tectonic gateways and climate on ocean acidification. Engineering Expeditions 390C and 395E cored a single hole through the sediment/basement interface with the advanced piston corer/extended core barrel system at five of the six primary proposed SAT sites and installed a reentry system with casing either into basement or within 10 m of basement at each of those five sites. Expedition 390 (7 April–7 June 2022) conducted operations at three of the SAT sites, recovering 700 m of core (77% recovery) over 30.3 days of on-site operations. Sediment coring, basement drilling, and logging were conducted at two sites on 61 Ma crust, and sediment coring was completed at the 7 Ma crust site. At Site U1557 on 61 Ma crust, the drill bit was deposited on the seafloor prior to downhole logging, leaving Hole U1557D available for future deepening and to establish a legacy borehole for basement hydrothermal and microbiological experiments. Expedition 390 scientists additionally described, and analyzed data from, 792 m of core collected during Expeditions 390C and 395E. Expedition 393 plans to operate at four sites, conducting basement drilling and downhole logging at the 7 Ma site, in addition to sediment coring, basement drilling, and logging at the sites intermediate in age.
