This data is part of the BMBF projects CUSCO (Coastal Upwelling Systems in a Changing Ocean) and BioTip subproject Humboldt Tipping. The file contains total dissolvable trace...

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.

This dataset includes geochemical measurements made on planktic foraminifers (Morozovella velascoensis) recovered from sediment cores spanning the Paleocene-Eocene Thermal...

Calcium isotope ratios (δ44Ca) and minor/trace elemental ratios (Mn, Sr, U, V, Cr, Fe /(Ca + Mg)) were measured from bulk carbonate powders in 2023 on samples collected in 2006...

The Bølling-Allerød deglacial event is marked by high diatom productivity and opal deposition throughout the subarctic Pacific. To investigate the cause of this event, we...

During the PS133/2 research cruise with the German research vessel RV Polarstern in the austral summer of November and December 2022 into the Southern Ocean, sediment samples...

We determined δ26Mg values in the dominant tree species and organic layer along the 127 year-old Hailuogou glacial retreat chronosequence (southwest China), which is...

This dataset contains dissolved oxygen (DO) concentrations, stable oxygen isotope ratios of DO (δ¹⁸ODO), particulate organic carbon (POC) concentrations, and...

Authigenic neodymium isotope (εNd) analyses were carried out on uncleaned mixed planktonic foraminifera. Around 60 mg of planktonic foraminifera shells were handpicked from the...

This dataset combines Mg/Ca ratios, sea surface temperatures, and stable isotope values (δ¹³C, δ¹⁸O) for planktic foraminifera from IODP Site 392-U1580, which is located at...

We collected water samples from the river surface in the center of the Olenekskaya Channel near Samoylov Island using a pre-rinsed HDPE 1 L bottle. During the open water period...

Boron isotope, stable isotope and trace elemental composition of fossilised Liostrea hisingeri oyster samples and sequentially leached paired bulk rock samples. Samples were...

This data set is an extension to the previously published data in a bundled publication (Stieg et al., 2024a) from the Russian Lake Khamra (59.99°N, 112.98°E, 340 m a.s.l.),...

Ten sea ice cores were drilled close to each other with a Kovacs 9 cm diameter corer (Kovacs Enterprise, Roseburg, USA) on April 8, 2020, near the main sampling site (MCS) for...

Seawater samples were collected from the MOSAiC Central Observatory, which consisted of sampling facilities positioned on the main sea-ice floe (including Ocean City) and on the...

This dataset includes seawater neodymium (Nd) concentrations and Nd isotope signatures (expressed as ε-Nd) obtained from a zonal deep-water (1500 – 5321 m water depth) transect...

In laboratory culture experiments, phytoplankton species were exposed to a range of nickel concentrations at GEOMAR Helmholtz Centre for Ocean Research Kiel. The experiments...
