title: Positioning and telemetry from ROV survey PS122/1_9-22 on 2019-11-26, survey 1

description: The horizontal position of the remotely operated vehicle (ROV) during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition between November 2019 and September 2020 was measured using an acoustic Long Base Line (LBL) positioning system (LinkQuest Pinpoint). The position was recorded in the SPOT.ON survey systems software (OceanModulesTM). The track was smoothed from initial acoustic fixes and cleaned for most obvious outliers. The position is in a floe-fixed, relative coordinate system (X, Y) with the origin (X=0 m, Y=0 m) at the ROV hole. A quality flag for the position is introduced based on the time to the closest fix with “1” indicating good positon (fix reached &lt;= 3s), “2” medium position (fix reached &gt; 3s & &lt;= 5s), and “3” bad position (fix reached &gt; 5s). Depending on the scientific aim, a position with quality flag “3” can still be useful. Vehicle depth was measured by the integrated pressure sensor and calibrated to 0 during pre-survey procedures, when the top side of the vehicle was at the same level as the water surface. Vehicle attitude (roll, pitch, heading) was measured with an onboard inertial measuring unit (IMU, Microstrain) with three axis accelerometer, magnetometer and gyroscope. Depth was measured by a pressure sensor (Keller A-21Y, Keller AG) included in the main electronics housing of the ROV.
description: Horizontal position (X,Y):• Leg 1: Scale factors and offsets to successfully improve positions for surveys PS122_1_5_62_20191102_1 and PS122_1_6_16_20191105_1 were obtained by comparing positions of markers from the ROV and a terrestrial laser scanner (RIEGL). Scale factors and offsets for surveys PS122_1_6_31_20191106_1, PS122_1_6_118_20191110_1, PS122_1_7_18_20191112_1, PS122_1_7_55_20191113_1 are based on estimates but will be improved also using markers.• Leg 4: Positions for surveys PS122_4_48_213_20200726_1 and PS122_4_49_105_20200728_1 are partly distorted probably due to usage of drifting transponder(s) or erroneous transponder position configuration. Retrieving suitable scale factors and offsets was not successful so far.• Leg 5: probably due to drifting transponder(s). Retrieving suitable scale factors and offsets was not successful so far.

title: Secchi disk observations in the coastal waters of the Northern Adriatic Sea aboard R/V Dallaporta in 2021

description: A white Secchi disk with a diameter of 30 cm with a lead weight at the bottom was used during the field campaign aboard the R/V Dallaporta between 14 and 27 March 2021. At selected station the Secchi disk depth was recorded as a relative measure of water clarity, detailed approach is presented in open-access (Garaba et al., 2015; Wernand, 2011). The Secchi disk is lowered until it is no longer visible and the depth at which it disappers is recorded from the surface. The measurements is then used to describe water clarity as clear or turbid using the Secchi disk depth in meters as an index. Stations were located in the Po Delta and coastal waters of the Northen Adriatic Sea.

title: Tellurium analyses of 12 samples of manganese oxide nodules from the Pacific and Indian Oceans

description: As a part of a continuing study of the distribution and abundance of tellurium in various materials of the earth's crust, analyses were made of 12 samples of manganese nodules from the Pacific and Indian Ocean. The quantitative determination of tellurium is based on the induced precipitation of elemental gold from a 6NHCl solution containing gold chloride, cupric chloride, and hypophosphorous acid; the amount of gold reduced is proportional to the amount of tellurium present. As little as 1 nanogram (1 × 10-9 g) of tellurium gives a measurable reaction with 1 mg of gold in 50 ml of solution.
description: From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.This dataset represents the digitized Table 1, pp. 1568 of the related publication. However, the authors have apparently transmitted to NOAA-NGDC more analysis results for some samples than in the published table of the report.

title: Benthic isotopes of ODP Hole 130-807A

description: This data file contains benthic foraminiferal oxygen isotope (δ¹⁸O) and carbon isotope (δ13C) records from ODP Site 807 A. Data from the depth intervals 0.17–8.37 mbsf and 26.27–42.37 mbsf were previously published in Zhang et al. (2007) and Du et al. (2016), respectively. Isotope measurements are based on the &gt;150µm fraction of C. wuellerstorfi where available. If C. wuellerstorfi was not available, specimens of U. peregrina and C. mundulus were used for analysis. All stable isotopic analyses were performed at the State Key Laboratory of Marine Geology, Tongji University on Finnigan MAT 252 or 253 mass spectrometers. External reproducibility based on replicate analyses of benthic foraminiferal samples is 0.07‰ and 0.04‰ for δ18O and δ13C.Various benthic foraminiferal species fractionate oxygen and carbon isotopes differently when forming tests, resulting in offsets in δ18O and δ13C. To account for this, we adopted such conventional correction factors of C. wuellerstorfi and C. mundulus/Uvigerina peregerina that 0.64 ‰ was subtracted from the δ18O and 0.9 ‰ was added to the δ13C of Uvigerina peregerina (Duplessy et al., 1984; Shackleton, 1974).
description: rmbsf: For Hole 807A, the high recovery exceeding 100% in the section cored with the APC (0–254.4 mbsf) results in overlapping depth (mbsf) between two adjacent cores. To avoid this, we adopted a new depth scale, the revised meter below sea floor (rmbsf) for the isotopic samples" (Feng et al., 2022).

title: Physical oceanography (CTD) during POSEIDON cruise POS466

description: Seabird 911plus systems equipped with dual temperature-conductivity-oxygen sensors were employed. All systems had a 24-bottle water sampling rosette with 10 l Niskin bottles. Water sampling, processing, and calibration followed GO-SHIP recommendations (Swift, 2010; McTaggart et al., 2010; Uchida et al., 2010) and included the recommended steps Data Conversion, Sensor Time-Alignment, Creation of Bottle Files, Outlier Removal, Pressure Sensor Filtering, Conductivity Cell Thermal Mass Correction, Ship Roll Correction and Deck Offset Correction by Loop Editing, as well as Derivation of Calculated Properties. After these steps, conductivity and oxygen readings were calibrated against values determined with salinometry and Winkler titration , respectively. Finally, the downcast data was averaged over 1 dbar wide intervals. An independent upcast calibration was used to obtain calibrated CTDO values coincident with the discrete water samples.

title: Magnetic susceptibility of the lower Pliensbachian Santiurde section (Basque-Cantabrian basin, northern Spain)

description: We present magnetic susceptibility dataset from the lowermost Pliensbachian organic-rich hemipelagic Santiurde section (Basque-Cantabrian basin, north Iberian palaeomargin, Spain). The Santiurde section studied herein is exposed at exit 144 of motorway A67 (UTM X411431.091 Y4769002.593), approximately 50 km south-west of Santander city. The 22.5 m-thick succession is characterized by an alternation of limy and marl/shale beds. In order to determine if sedimentation was orbitally forced, a cyclostratigraphic analysis of the hemipelagic rythmites was undertaken. To this end, a total of 373 hand samples were collected and analysed for magnetic susceptibility and rock powder colour. Sampling was mainly carried out in 2019. The mass normalized low-field magnetic susceptibility was measured using a Kappabridge KLY-3 instrument (Geophysika Brno) housed at the Geology department of the University of the Basque Country (UPV/EHU), Bilbao, Spain.

title: Calcium carbonate of the lower Pliensbachian Santiurde section (Basque-Cantabrian basin, northern Spain)

description: We present calcium carbonate dataset from the lowermost Pliensbachian organic-rich hemipelagic Santiurde section (Basque-Cantabrian basin, north Iberian palaeomargin, Spain). The Santiurde section studied herein is exposed at exit 144 of motorway A67 (UTM X411431.091 Y4769002.593), approximately 50 km south-west of Santander city. The expanded hemiplegic succession offered a potentially valuable orbitally paced stratigraphic record. An integrated multiproxy study was performed in the 19 beds found between 12.4 and 15.95 m of the lower Pliensbachian succession in order to disentangle what sedimentary processes and environmental factors influenced the formation of the hemipelagic rhytmites. Sampling was mainly carried out in 2019. Fifty-seven samples were collected in order to analyse their %CaCO3 and inorganic d13Ccarb and d18Ocarb content. The calcimetric analysis was carried out measuring the carbonate percentage in 1 g of powder of each sample, using a FOGL digital calcimeter (BD inventions; accuracy of 0.5%) housed at the University of the Basque Country (UPV/EHU), Bilbao, Spain.
