Mineral composition of Heinrich events 8, 9, and 10 samples

Nine samples from Heinrich events 8, 9, and 10 were obtained from cores HU91020-074 and HU204024-042 which are located some 1900 km south of Hudson Strait in the area of the...

Gravel petrology of Hudson strait sediments

Sediments from channel samples were weighed and sieved through a 2 mm mesh. Granules >2 mm were visually identified with a binocular microscope and dolomite was separated...

Isothermal Remanent Magnetization (IRM) acquisition curves for the unclassifi...

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...

Unclassified IRD susceptibility and content, porosity and grain density of se...

IRD content is commonly assessed by weighing the detrital particles of the >125µm or > 1mm sieve fractions or by counting the IRD particles of the latter. Here we present...

Bulk rock magnetic property records of sediment core GeoB18530-1

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...

Grain-size distribution and grain-size dependent magnetic susceptibility of s...

Since the weight percentages of (classifiable) IRD particles > 1 mm and (unclassifiable, but separable) IRD particles > 125 µm both largely underestimate the total content...

Six linear regression models for the magnetic susceptibility of sediment core...

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...

Lithology-specific IRD counts of sediment core GeoB18530-1

Total and lithology-specific ice-rafted detritus (IRD) counts of sediment core GeoB18530-1 were determined by stereomicroscopically identifying, picking and counting all...

Extended age model of sediment core GeoB18530-1 by correlation of Ca/Sr recor...

The previously published 14C-AMS based chronology of GeoB18530-1 by Max et al. (2022; doi:10.1594/PANGAEA.943562), covering the upper 0 - 7.16 m core section down to Heinrich...

IRD composition and accumulation rates of Heinrich Event layers (H1-H6) and i...

The cumulative classified count record (in percentages) over ~2 cm resolution of each petrologically identified IRD lithologies within the stratigraphic units of Heinrich Layers...

Nonlinear Mapping (NLM) analysis of IRD content in Heinrich Event layers (H1-...

This 3D data set represents the result of a Sammon projection (Sammon, 1969; https://doi.org/10.1109/T-C.1969.222678), where the mean relative proportions of all classified IRD...

Principal Component Analysis (PCA) of IRD content in Heinrich Event layers (H...

The data matrix of 192 classified IRD count data from H1-H6 and I1-I5 (excluding I6 because of too low IRD counts) by 22 IRD lithologies...

Relative and absolute abundance records of three IRD particle groups and six ...

As detailed in Bukar et al. (2024), the 22 classifiable IRD lithologies can be group according to their preferred affiliation to Heinrich Layers (HL) and Interlayers (IL). Group...

Element ratio proxy records for dolomitic and granitic IRD content in sedimen...

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...

IRD flux and supporting data on two cores in the western North Atlantic

A series of catastrophic iceberg discharges termed Heinrich events punctuated the last ice age in the North Atlantic. During Heinrich events, coarse terrigenous debris released...
