title: Magnetic data of profile MSM122_H11 over the Hayes transform fault, North Atlantic, of MARIA S. MERIAN cruise MSM122

description: During the cruise MSM122 of the German research vessel MARIA S. MERIAN, we recorded densely spaced magnetic field measurement over the Oceanographer and Hayes transform faults in the North Atlantic to the Southwest of the Azores and hence at segment boundries offseting the Mid-Atlantic Ridge. Additional data were recorded to the south of Hayes transform and on the transits to Halifax outside of any territorial water.The total magnetic field was measured using two SeaSpy magnetometers which were towed at 350 m and 450 m, respectively, behind the stern of the ship, sampling the data continuously every 2 seconds. The ships navigation was corrected to match the position of the first magnetic sensor at 350 m behind the vessel. Uncorrected total field magnetic data are available in text/ascii format.

title: (Table T1) In situ methane concentrations of ODP Site 201-1230

description: A method for quantifying in situ dissolved methane concentrations in sediment cores that have gas voids is described. The method relies on normalizing methane (CH4) in the gas voids to nitrogen (N2) and/or argon (Ar). The principles of the method are presented. The method was tested during Ocean Drilling Program Leg 201, and preliminary results indicate that it can be used to generate reproducible and accurate dissolved methane values if argon and nitrogen are both measured or if one is measured along with pressure of the gas void.
description: Uncertainty is ±33% from the calculated mean. Sediment depth is given in mbsf.

title: Micro-computed tomography analysis of marine sediment samples of two piston cores, GS10-163-02PC (Norwegian fjord) and 64PE391-04 (offshore UK)

description: Two sediment samples (B043_20160307_SLS_1127_A3 and B052_20160307_SLS_1127_A5), taken from piston core GS10-163-02PC (66°10'57.358''N, 13°47'46.681''E; Vanneste et al., 2011; L'Heureux et al., 2012) at 2.95 metres below seafloor (mbsf) and 3.04 mbsf, respectively, and two sediment samples (B019_20160303_SLS_1127_B04 and B026_20160307_SLS_1127_A4), taken from piston core 64PE391-04 (61°15′40.679″N, 02°23′42.899″W; Gatter et al., 2020) at 9.18 mbsf and 9.25 mbsf depth, respectively, were scanned at the TOMCAT Beamline of the Swiss Light Source (SLS), Paul Scherrer Institute, Switzerland. A beam energy of 21 keV and a propagation distance of 81 mm were used to scan the samples. Per sample, 1501 projections (over 180° sample rotation) were recorded with an exposure time of 200 ms. The resultant micro-computed tomography (µCT) image stacks have a 3D voxel resolution of 0.325 µm (x-/y-/z-direction). Each reconstructed 3D image stack consists of 2160 individual 2D images (2560 x 2560 pixel). Images were reconstructed using the phase reconstruction algorithm described by Paganin et al. (2002). The data were processed using Fiji ImageJ (Schindelin et al., 2012) and Avizo 3D (version 2022.1). Within Fiji, the blurry edges that resulted from insufficient information for image reconstruction, were deleted from the datasets; thereby, the 2D image size was reduced from 2560 x 2560 pixel to 1730 x 1730 pixel. A first segmentation of solids and pores was performed using the Trainable Weka Segmentation 2D algorithm (Arganda-Carreras et al., 2017) within Fiji. The resultant binary images were used as input information for a second, more detailed, segmentation. In Avizo 3D, particles and pore space were segmented using a marker-based watershed algorithm and visualised in 3D. Subsequently, the sediment components were quantified using the 'Label Analysis' module in Avizo 3D.

title: Dissolved neodymium (Nd) isotope compositions and rare earth element (REE) concentrations along with stable oxygen isotope compositions measured on water bottle samples collected during PU2014 to the Barents Sea in 2014

description: Nearly half the inflow of warm and saline Atlantic Water (AW) to the Arctic Ocean is substantially cooled and freshened in the Barents Sea, which is therefore considered a key region for water mass transformation in the Arctic Mediterranean. Numerous studies have focused on this transformation and the increasing influence of AW on Arctic climate and biodiversity, yet geochemical investigations of these processes have been scarce. Using the first comprehensive data set of the distributions of dissolved radiogenic neodymium (Nd) isotopes (expressed as ɛNd), rare earth elements (REE) and stable oxygen isotope (δ18O) compositions from this region we are able to constrain the transport and transformation of AW in the Barents Sea and to investigate which processes change the chemical composition of the water masses beyond what is expected from circulation and mixing.Inflowing AW and Norwegian Coastal Water (NCW) both exhibit distinctly unradiogenic ɛNd signatures of -12.4 and -14.5, respectively, whereas cold and dense Polar Water (PW) has considerably more radiogenic ɛNd signatures reaching up to -8.1. Locally formed Barents Sea Atlantic Water (BSAW) and Barents Sea Arctic Atlantic Water (BSAAW) are encountered in the northeastern Barents Sea and have intermediate ɛNd values resulting from admixture of PW containing small amounts of riverine freshwater from the Ob (&lt; ~1.1 %) to AW and NCW. Similar to the Laptev Sea, the dissolved Nd isotope composition in the Barents Sea seems to be mainly controlled by water mass advection and mixing despite its shallow water depth. Strikingly, the BSAW and BSAAW are marked by the lowest REE concentrations reaching 11 pmol/kg for Nd ([Nd]), which in contrast to the Nd isotopes, cannot be attributed to the admixture of REE-rich Ob freshwater to AW or NCW ([Nd] = 16.7, and 22 pmol/kg, respectively) and instead reflects REE removal from the dissolved phase with preferential removal of the light over the heavy REEs. The REE removal is, however, not explainable by estuarine REE behavior alone, suggesting that scavenging by (re)suspended (biogenic) particles occurs locally in the Barents Sea. Regardless of the exact cause of REE depletion, we show that AW transformation is accompanied by geochemical changes independent of water mass mixing.
