Physical properties (MSCL) of IODP Hole 389-M0104A
No full textMulti-Sensor Core Logger (MSCL) data (P-wave velocity, magnetic susceptibility, natural gamma radiation (NGR), noncontact resistivity (NCR), gamma ray attenuation (GRA) density) from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). These data were obtained from whole round core sections by means of a Geotek MSCL during the offshore phase of the expedition. The offshore phase of this expedition took place between 2023-08-31 and 2023-10-31 onboard multipurpose vessel MMA Valour sailing from and to Barbers Point Harbor, Hawai'i, USA. During expedition 389 offshore operations, the recovered cores were transferred from aluminum to plastic liners, thereby draining and to some extent further disturbing the core sections. Thus, partial fluid saturation and drilling-induced core damage on top of natural vugs and fractures common in carbonates and volcanic lava rocks negatively impacted the data quality. GRA density, P-wave velocity, NCR, and magnetic susceptibility were measured every 2 cm, and NGR measurements were obtained every 10 cm. Note, in contrast to standard IODP syntax in this data set the depth value at the end of the sample label identifier, gives the depth in core. For instance, a sample label like 389-M0101B-19-2,126 identifies a measurement from 126 cm depth in core 19 (corresponding to section 2) within hole M0101B of expedition 389.

Line scan images of IODP Hole 389-M0098A
No full textCollection of line scan images from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). The offshore phase of this expedition took place between 2023-08-31 and 2023-10-31 onboard multipurpose vessel MMA Valour sailing from and to Barbers Point Harbor, Hawai'i, USA, followed by the onshore phase from 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. Line scan images were obtained during the onshore phase from the cleaned fresh cut surfaces directly after longitudinal splitting of core sections into work and archive halves. Images were obtained using the line scan sensor of the Avaatech Superslit X-ray fluorescence (XRF) core scanner in operation at MARUM. The line scan program of this scanner uses the Stemmer Common Vision Blox platform to acquire and process color images. Image resolution is ~150 pixel/cm in the crosscore and downcore direction. All split cores were measured using aperture setting f/11+ (a fixed value between 11 and 16). When cores were darker (e.g., in lava), the aperture was increased to up to f/5.6, and for lighter rocks (e.g., some corals) the aperture was decreased to f/13. This dataset includes the curated cropped images of working and archive halves for the best fitting aperture, respectively. File naming follows standard IODP file naming convention: Exp-SiteHole-CoreCoretype-SectionHalf. For example, a file 389-M0109A-06R-1W.jpg identifies the image of the working half of section 1, core 6R (R indicating rotary coring method), from Hole M0109A from Expedition 389.

P-wave velocity of discrete samples (DPW) from IODP Hole 389-M0099B
No full textP-wave velocity data from discrete samples from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). Discrete samples for P-wave velocity measurements were taken during the onshore phase of expedition 389, which took place between 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. The measurements were performed on cylindrical core plugs drilled approx. every 1.5 meter perpendicular to the split surface of the working halves of the core sections. P-wave velocity was measured first wet straight after the initial sampling, again after the samples have been dried in a convection oven and a third time after being resaturated with tap water. All measurements were performed with a Geotek PWL-D velocimeter for discrete P-wave measurements.

No full textRaw data acquired by position sensors on board RV Elisabeth Mann Borgese during expedition EMB365 were processed to receive a validated master track which can be used as reference of further expedition data. During EMB365 data from the motion reference unit exail Phins Gen.3, the Trimble SPS356 GPS receiver, the Furuno GP-170 and the Furuno GP-150 GPS receiver were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (https://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track

Moisture and density (MAD) from IODP Hole 389-M0096D
No full textMoisture and density (MAD) data from discrete samples from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). MAD measurements were performed on the same samples as P-wave velocity (the same sample was used for both measurements). These discrete samples were taken during the onshore phase of expedition 389, which took place between 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. Where core quality allowed cylindrical plugs were drilled perpendicular to the split core surface at an interval of one sample per core (approx. every 1.5 meter). MAD properties (bulk density, dry density, grain density, water content, porosity, and void ratio) were determined from measurements of the wet and dry mass of the sampled core plugs as well as their dry volumes. Drying took place in a convection oven at 105°±5°C for 24 hours.
