    3D multichannel seismic reflection processed data (P-Cable system with GI Gun) of RV POSEIDON during cruise POS515, Calabrian Arc, Mediterranean Sea (2024)
    PANGAEA
    Details
    Publication Date: 2024-06-01
    Description: The data are a processed and interpolated P-Cable 3D seismic data cube. The data were collected during expedition POS515 with the research vessel POSEIDON (Riedel et al., 2017) in the Mediterranean Sea, Calabrian Arc offshore southern Italy (map under further details). Seismic source was a Generator-Injector airgun fired in harmonic GI mode with generator and injector volume of 105 cubic inches. The source was towed at a nominal depth of 2 m beneath the sea surface. We deployed a P-Cable system made from 12 parallel streamers (each 12. 5 m in length). Details on the towed geometry are given in Figure 30 of the cruise report (Riedel et al., 2017). The P-Cable data were acquired over the course of 6 days during POS515 starting from 13:45 on July 5, 2017 until 12:06 on July11, 2017 (all CET). Processing included: 3D geometry application, trace editing, static time corrections, band-pass filtering, sorting to common midpoint gathers, normal moveout correction (1520 m/s velocity ), and stacking. The stacked 3D cube was then interpolated to fill any empty bins. Afterwards, Stolt time migration (1550 m/s) was performed, first inline, then crossline direction. The dataset has a horizontal resolution of 3.125 m (bin size) and a dominant frequency of ~100 Hz.

    2D multichannel seismic reflection processed data (GI Gun working area dataset) of RV POSEIDON during cruise POS515, Poseidon mud volcano chain, Calabrian Arc, Mediterranean Sea (2024)
    PANGAEA
    Details
    Publication Date: 2024-06-01
    Description: The data set contains 13 2D multichannel seismic lines acquired across Poseidon mud volcano chain, Caalbrian Arc, offshore southern Italy. Data were processed onboard during expedition POS515 with R/V POSEIDON. These lines were also recorded on 12 OBS. Details see cruise report (Riedel et al., 2017). Main processing steps include: Geometry definition, Common-Mid-(CMP) Point sorting (1.5625 m bin-space), Normal-Moveout-Corrention (NMO) using a constant velocity of 1500 m/s and Stacking Stolt-Migration (in time) with constant velocity of 1500 m/s. Data processing was completed onboard using the SU processing package. Seismic Surveying at Poseidon mudvlcano started with line P4001 on July 3, 2017 (08:22 am, CET) at 17°40.12'E, 38°21.58N. The last line acquired in this sequence is line P6010. Surveying ended on July 5, 2017 at 04:00 am (CET) at 17°43.12'E, 38°18.96'N.

    Loss on ignition, water content, and pH measurements in surface sediments (2022) within DynaCom experimental islands and saltmarsh enclosed plots at different elevation levels, Spiekeroog, Germany (2024)
    PANGAEA
    Details
    Publication Date: 2024-06-01
    Description: Data presented here were collected between January 2022 to November 2022 within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems) of the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were created in the back barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog. Sediment samples for the determination of pH, water content and loss on ignition were taken bi-/monthly in surface sediments (0-3 cm depth) from the experimental plots. Samples were stored dark and cool (8°C) until measurement. Samples were measured in the laboratory within two months after sampling. Water content (w, [-]) was determined by first weighing the fresh sample (mf; ~ 3-7 g) in pre-weighed aluminium trays and than placed in the drying chamber at 105 °C for 12 hours. After placing samples in the exsiccator for 60 min., samples were re-weight to determine dry weight (md). Water content was calculated using w = (mf - md) / md . Afterwards, samples were placed in the muffle furnace for 2 hours at 430 °C within their aluminium trays, and placed again in the exsiccator for 60 min. Samples were re-weighed to determine the new dry weight (mgl) to calculate loss on ignition (LOI, [%]) using LOI = ((md – mgl) / md ) * 100 . Values of pH were measured according to DIN ISO 10390. Therefore, soil samples were weighed in pre-weighed Falcon™ 50 mL conical centrifuge tubes. Sediment samples were homogenized using a pestle. Ultrapure water was used to measure pH directly within the tubes using a HQ40D digital two channel multi meter and an Intellical PHC101 field low maintenance gel filled pH electrode (Hach Lange GmbH, Germany). The pH electrode was calibrated before measurement using singlet pH buffer sets (pH 4.01, 7.00, 10.01) for single use (Hach Lange GmbH, Germany). Post-processing of measured values were done using MATLAB (R2018a). Quality control was performed by (a) visually checks, and hence (b) the classification into quality control flags using quality check algorithms.

    Bulk total organic carbon content and its isotope composition and biomarker data of sediment core YC22_MR_7 off Herschel island (Yukon Coast 2022) (2024)
    PANGAEA
    Details
    Publication Date: 2024-06-01
    Description: In July 2022 within the framework of an Alfred-Wegener-Institute-managed expedition and the Nunataryuk project, sediment core YC22_MR_7 was taken off the coast of Herschel Island, Canada, using a hand corer. Data sets were obtained to investigate carbon feedback from the sediments to the water column and atmosphere, using DIC concentrations and isotopic values. The local sediments are supplied primarily by organic carbon previously stored in adjacent permafrost soils (biomarker and bulk data), which erode and redeposit quickly (age model) on the ocean floor. The acquired data includes: 1) Sediment data: Bulk total organic carbon content (Lamping et al., 2021) and its isotopic values for 13C (Brodie et al., 2011; Werner & Brand, 2001) and 14C (Mollenhauer et al., 2021). 2) Biomarker data: Quantifying alkanes (CPI) , and fatty acids (TAR ratio) as described by Wei et al. (2020), Glycerol dialkyl glycerol tetraethers (GDGTs basis for BIT-Index) after Hopmans et al. (2016), Hopanes (fßß) following instructions by Meyer et al., (2019), and Sterols (Dinosterol) after Dauner et al. (2022).

    Description: This dataset presents user-defined tiepoints of the manual alignment of the benthic foraminiferal δ¹⁸O record at ODP Site 980 and 981 to the benthic foraminiferal LR04 δ¹⁸O stack of Lisiecki and Raymo (2005) obtained by Middleton et al. (2024). The benthic foraminiferal δ¹⁸O record at ODP 980 is based on Cibicidoides wuellerstorfi and Cibicides kullenbergi, and was previously published (McManus et al., 1999; Flower et al., 2000; Oppo et al., 1998). The ODP Site 981 data were measured on benthic foraminifera of the genus Cibicidoides (Raymo et al., 2004). The benthic foraminiferal δ¹⁸O records of ODP Site 980 and 981 were spliced together at ~860 ka (Raymo et al., 2004).
