Physical properties (MSCL) of IODP Hole 386-M0090D
No full textMulti-Sensor Core Logger (MSCL) data (P-wave velocity, gamma ray attenuation (GRA) density, magnetic susceptibility, natural gamma radiation (NGR), noncontact resistivity (NCR)) from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). 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 expedition 386 took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. As the aforementioned parameters are sensitive to temperature core sections were stored for at least 6 hours after arrival on deck before measurement to allow for temperature equilibration. The core physical properties were measured at predetermined optimal instrument-based spatial and temporal sampling intervals. GRA density, P-wave velocity, NCR, and magnetic susceptibility were measured every 2 cm, and NGR measurements were obtained every 10 cm.

Core-section summary for IODP Site 386-M0083
No full textList of recovered core sections from the above given site of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The offshore phase of this expedition took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. Cores have been acquired by the use of a Giant Piston Coring (GPC) System. Recovered cores were divided into approx. 1 m long sections that are numbered sequentially from the top, starting at 1. Following IODP convention, material recovered from the core catcher of a sedimentary core is treated as a separate section labelled CC for core catcher and placed below the last section recovered from the core barrel. Most core catcher sections were placed in a bag due to their consistency. The IODP standard naming of sections includes the following information: expedition number, hole, core, core type and section. For example, a section label (column "Sample label") "386-M0081D-1H-12" represents section 12, core 1H ("H" [for hydraulic piston corer] indicates GPC cores, and "P" [for push corer] indicates trigger corer cores; see core summaries of this expedition), from Hole M0081D during Expedition 386.

Viability, culturability and DNA loss rate obtained for collected bacteria after filter and impingement-based sampling
No full textViability, culturability and DNA loss rate were obtained for collected bacteria after filter and impingement-based sampling. The sample extracts were spread on TSA plates. The inoculated TSA plates were incubated at 37℃ for 1 day, and colony forming units (CFUs) were counted for culturable fungi. Dual-fluorescence method for accurate viability analysis of test samples was performed. With an appropriate mixture of AO/PI, total cells were stained with AO whereas damaged cells were stained with PI. An epifluorescence microscope was used to count the test sample's bacterial cells on the filter at a magnification of 400x. The culturability is determined by percentage of CCFU in CAO while percentage of (CAO-CPI) in CAO is for viability. The qPCR was performed on LightCycler 480 for DNA quantification with universal primers of DG74 (5'-AGGAGGTGATCCAACCGCA-3') and RW01 (5'-AACTGGAGGAAGGTGGGGAT-3') targeting on a conserved 370-bp region of 16S rRNA gene. The DNA loss rate was determined by the ratio of DNA concentrations in the supernatant sample to total DNA concentrations in the entire sample (supernatant sample + pellet sample)
Arctic PASSION - Polar Monthly Mean Ice Surface Temperature (AP-MMIST) for the time period 1982 to 2024
No full textThe Arctic PASSION Polar Monthly Mean IST data set (AP-MMIST) is a combined surface temperature product covering open ocean, marginal ice zone and closed sea ice areas, represented by Sea Surface Temperatures (SST), Marginal Ice Zone Temperatures (MIZT) and sea Ice Surface Temperatures (IST). Beside ocean and sea ice the data set also includes surface temperatures from the Greenland and Antarctic ice sheets. AP-MMIST has been jointly developed and produced by Arctic PASSION WP-1 and the Sea Ice Thematic Assembly Centre (Sea Ice TAC) under the Copernicus Climate Change Service (C3S - service contract: 2022/C3S2_312b_MOi_SC1). The AP-MMIST is a monthly averaged temperature product based on the C3S daily IST CDR and ICDR level 3 data. The daily mean C3S IST data set is a resampled and averaged daily mean IST product using Global Area Coverage - Advanced Very High-Resolution Radiometer (AVHRR) IST level 2 data as input. The level 2 and 3 CDR and ICDR data records are described in Algorithm Theoretical Baseline Document (Eastwood et al., 2023). The surface temperature retrieval algorithm used to produce the basic level 2 product is a traditional split window algorithm using two Thermal InfraRed (TIR) channels to compensate for atmosphere and angular emissivity dependency. This is described in the Algorithm Theoretical Baseline Document (Eastwood et al., 2023). The level 1 TIR input data set is the full data record from the AVHRR on-board NOAA satellite platforms since 1982, as well as AVHRR records on-board Metop satellites since 2006. The product output format is NetCDF with standard attributes, following CF convention to the degree possible. The monthly data are divided into 2 monthly files, one for each hemisphere, SH and NH
Color data (RGB) of IODP Hole 386-M0085A
No full textColor data obtained from split core sections from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology) during the onshore phase. The onshore phase of expedition 386 took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. After longitudinal splitting of the core sections, high-resolution (100 pixels/cm) images of archive half was captured using the Tri-Sensor Core Logger (TSCL; NS Design). The camera provides a 16-bit red-green-blue (RGB) color (48-bit) TIFF file from which the RGB data were derived in 1 mm down-core resolution. For each section: 1) the TIFF file (from line scanning) full resolution was opened and channels scaled to 0-255; 2) TIFF file cut at top (2475 px) and bottom (2470 px + length of the section x resolution); 3) for every line of pixel down section, R, G, B values were averaged over a width of 450 px across the centre of the section (\~4.5 cm width) and data placed into a table compiling all sections of a hole; 4) for every depth interval, where a piece of sponge was observed on the linescan, R, G, B data were deleted; 5) R, G, B data were also deleted to the top and bottom ~1 cm of each section, to account for possible gaps or pieces of liner.
