Master tracks in different resolutions from POLAR 5 flight P5-258_PERMA-X_2025_2508081101
Dissolved REE concentrations in near-bottom water samples from RV Meteor cruise M147
All samples were obtained during RV Meteor cruise M147 (April–May 2018), conducted as the official process study GAPR11 within the framework of the international GEOTRACES program
Reference material for near-bottom water ansd sediment samples from RV Meteor cruise M147
Nd and Hf isotope compositions of secondary standard solution and reference materials for checking the external reproducibilit
Master tracks in different resolutions from POLAR 6 flight P6-259_IceBird_Summer_2025_2508181001
Annual stalagmite-derived SSTs for Bermuda (1449-2013)
Mean annual SSTs spanning the last ~564 years modelled from a calibration with a previously-published coral record. The confidence interval (95%) reflects purely the calibration uncertainty
Major element glass data of marine tephras from sediment core M141/1_1140-1
A total of 44 gravity cores were collected in the Azores region in 2017, during the R/V Meteor cruise M141/1. Based on their length, content in tephra layers, and spatial distribution around São Miguel, 22 cores have been carefully selected as the most representative to gain insights on the volcanic history and the depositional marine environment around the islands of the eastern group of the archipelago. In total, 454 samples from 350 ash- or pumice/scoria/lapilli- bearing horizons were examined. Here we present the major element glass data of the Pleistocene to Holocene marine tephra record around the eastern islands of the Azores. Marine lapilli samples were cleaned in an ultrasonic bath and then crushed. All ash samples and the previously crushed lapilli samples were wet-sieved into different grain size fractions. The 125-63 microns fraction was embedded with epoxy in pre-drilled acrylic mounts and polished for geochemical micro-analyses. Major and minor element compositions of glass shards were conducted using a JEOL JXA 8200 wavelength dispersive EMP at GEOMAR Helmholtz-Centre for Ocean Research, Kiel, Germany.
Every 60 individual glass shards analyses were bracketed by a set of four standard analyses. We analyzed 15–25 single glass shards per sample (~7,000 analyses in total). Outliers with totals below 92 wt.%, as well as accidental mineral analyses were removed from the dataset
