title: Isothermal Remanent Magnetization (IRM) acquisition curves for the unclassified IRD &gt; 1mm fractions of sediment core GeoB18530-1

description: IRM acquisition curves (and their derivatives) resolve the cumulative coercivity distribution (and spectrum) of a magnetic mineral assemblage. Here we present IRM data for all extracted unclassified IRD &gt; 1mm fractions. The IRM acquisition curves were acquired in logarithmically increasing pulse field steps from 10 mT to 2600 mT and measured by DC SQUIDS inside the 2G rock magnetometer without exposure to the external geomagnetic field. The varying magnetic peak field values shown here are based on real time peak field measurements by an integrated induction coil. Although samples were previously AF demagnetized, but some samples have hard initial remanent magnetizations, that could not be entirely removed.
description: Corresponds to Figure 5a.

title: Element ratio proxy records for dolomitic and granitic IRD content in sediment core GeoB18530-1

description: Because of its sensitivity for detrital dolomite, the Ca/Sr ratio of sediment core GeoB18530-1 was previously used to identify Heinrich Event layers (doi:10.1594/PANGAEA.943557 and doi:10.1594/PANGAEA.943556). As Ca/Sr is also influenced by marine sedimentation, the relative Ca/Si and Sr/Si variations given here allow assessing the detrital vs. marine carbonate mixing system. We newly introduce the K/Fe ratio as proxy for the volumetrically and magnetically very relevant granitic IRD deposition and support this interpretation by comparing K/Si and Fe/Si ratios. The element data presented here were acquired with the MARUM Aavatech XRF Scanner at acceleration voltages of 10 kV, 30 kV and 50 kV (Max et al., 2022). All six element ratios, which were initially scaled in peak area units, have been normalized to their interlayer means in order to facilitate the quantitative unmixing of HL-related and -unrelated sediment fractions. The magnetic susceptibility estimate derived by multiple regression from Ca/Sr and K/Fe ratios is contained in the model data set doi:10.1594/PANGAEA.971771.

title: Isothermal Remanent Magnetization (IRM) acquisition curves for petrologically representative IRD particles of sediment core GeoB18530-1

description: IRM acquisition curves (and their derivatives) resolve the cumulative coercivity distribution (and spectrum) of a magnetic mineral assemblage. Here we present data of larger, petrologically representative IRD particles of all observed lithologies. These IRM acquisition curves were acquired in logarithmically increasing pulse field steps from 10 mT to 2600 mT and measured by DC SQUIDS inside the 2G rock magnetometer without exposure to the external geomagnetic field. The varying magnetic peak field values shown here are based on real time peak field measurements by an integrated induction coil. Although samples were previously AF demagnetized, some samples have hard initial remanent magnetizations that were not entirely removed.

title: Bulk rock magnetic property records of sediment core GeoB18530-1

description: Standard remanence-based dry-bulk rock magnetic parameters were determined in 2.3 cm steps along core GeoB18530-1 using an automated 2G Enterprises 755R DC SQUID Magnetometer with built-in AF, DC and pulse coils. The 6.2 cm³ large cube samples were measured in water-saturated state and subsequently dried and weighed in order to convert their magnetic moments to dry-mass-specific remanent magnetization, thereby eliminating the magnetic impact of porosity variations. The herein published data for IRM_20mT, IRM_100mT, ARM_100mT, HIRM, SIRM/χ and S_0.3T are diagnostic for magnetic mineral composition and were selected from a much larger raw data series based on 28 pulse field steps from 10 mT to 2.7 T. The chosen core depth range from 4.88 m to 10.60 m includes six Heinrich Event Layers and their surrounding interlayers.

title: Grain-size distribution and grain-size dependent magnetic susceptibility of sediment core GeoB18530-1

description: Since the weight percentages of (classifiable) IRD particles &gt; 1 mm and (unclassifiable, but separable) IRD particles &gt; 125 µm both largely underestimate the total content and magnetic impact of IRD, it is important to quantify also the finer IRD fractions and their magnetic susceptibilities. From each of the IRD-rich sediment units H1, I1 and H2, six magnetic cube samples of 6.2 cm³ each were combined, dried, weighed and ultrasonically suspended in water. These three slurries were successively washed through 16 stacked sieves with mesh sizes in approximately 0.5 phi steps from 4000 µm to 5 µm using a Fritsch wet sieve shaker. The sieve fractions were carefully collected, dried, weighed and measured in a Kappabridge KLY2 susceptometer. The data and therefrom-derived partial susceptibilities and cumulative distributions clearly demonstrate that the magnetically most dominant and "volatile" sediment particles fall into the 40-125 µm range. Detrital particles of such sizes are too coarse to have been current-transported over long distances and were therefore probably at least partially ice-rafted.
description: Corresponds to Figure 6.

title: Six linear regression models for the magnetic susceptibility of sediment core GeoB18530-1

description: Six linear regression estimates of magnetic susceptibility were empirically tested for their ability to predict distinct HLs and ILs signal patterns. As predictors, we used MD magnetite content (IRM 20 mT), magnetic grain size (SIRM/X), dolomite and granite proxies (Ca/Sr and K/Fe), bulk porosity (%), dolomite and granite counts, and counts of the major 13 IRD species. As the obtained numbers and residues demonstrate, the rock magnetic proxies yield the best fits, followed by element ratios and porosity. The count-based predictors are incapable of estimating the older HLs 3-H5a and ILs 4-6 correctly; their regression coefficients also do not conform to the measured susceptibilities of the IRD species.
description: Corresponds to Figure 7.

title: Unclassified IRD susceptibility and content, porosity and grain density of sediment core GeoB18530-1

description: IRD content is commonly assessed by weighing the detrital particles of the &gt;125µm or &gt; 1mm sieve fractions or by counting the IRD particles of the latter. Here we present these three sedimentological records together with the correctly measured, but numerically rather erratic magnetic susceptibility record of the IRD &gt; 1mm fraction. The spiky character of sieved IRD susceptibility displays the stochastic nature of large IRD particle deposition. Systematic variations in IRD coarseness (calculated as ratio of IRD &gt; 1mm and IRD &gt;125µm) and bulk sediment porosity suggest considerable grain size variability of the glaciomarine Sediment fraction, while bulk particle density is almost constant at values of 2.7-2.8 g/cm³.

title: Phytoplankton pigment and phytoplankton group chlorophyll-a concentrations during POLARSTERN cruise PS126 from North Sea to Fram Strait in May to June 2021 from HPLC analysis of water samples

description: Phytoplankton pigments were determined in the water surface (from 0 to 11 m depth) of a transect from the North Sea to Fram Strait and back during RV Polarstern expedition PS126 from 24 May to 25 June 2021. Water samples were collected from CTD Niskin bottles at five to six different depths from the upper 100 m at CTD stations and from underway sampling. Between 0.4 to 3.5 L of each seawater sample was filtered through Whatman GF/F filters. The sample filters were then shock‐frozen in liquid N2 and kept at−80 °C until analysis. High Pressure Liquid Chromatography (HPLC) was performed to quantify various phytoplankton pigments (see Table 1 in Taylor et al. 2011) following the method of Barlow et al. (1997) that was adjusted to our temperature‐controlled instruments as detailed in Alvarez et al. (2022).
