Supporting metadata for multiple oceanographic cruises with RV SONNE (SO254, SO245, SO248) and RV POLARSTERN (PS79), Bermuda Atlantic Time-series Study and Hawaii Ocean Time-series

The data presented here include the metadata (cruise, station number, geographic coordinates, water depth, temperature, salinity and solid-phase extracted dissolved organic carbon concentrations (SPE-DOC)) for multiple oceanographic cruises in the Atlantic, Pacific and Southern oceans (HOTS, BATS, SO254, SO245, SO248, ANT 28-II, ANT 28-IV, and 28-V) between 2009 and 2017. These metadata were used in conjunction with the accompanying dataset to assess the role of deep ocean mixing in the molecular composition of dissolved organic matter was compiled from the CTD bottle data of multiple cruises, some of which are available on PANGAEA at the following links: SO248: https://doi.org/10.1594/PANGAEA.864673, SO245: https://doi.org/10.1594/PANGAEA.890394, SO254: https://doi.org/10.1594/PANGAEA.890453.

Experimental data on enhanced benthic weathering in Baltic Sea sediments from winter 2025

This data collection comprises sedimentary porewater, solid-phase, microprofile measurements, cell counts and microbial sulfate reduction rates, from a calcite amendment laboratory experiment. The sediment cores for the experiment were collected in Kiel Bight in February 2025 (cruise L25-02b). For that, six sediment cores were collected and kept in MUC core liner in the dark in the cool room at 8°C for the timespan of the experiment at GEOMAR, Kiel. Furthermore, water sample data from within the core liner were taken at regular timesteps. Three sediment cores were incubated with 7.86 g of grounded limestone (>99% calcium carbonate) distributed at the sediment surface; additional three unamended treatments were used as reference. All sediment cores were kept under controlled oxygen depletion and subsequent reoxidation cycles. Data includes organic carbon (COrg), calcium carbonate (CaCO3), sulfur (S, %) and data from sequential iron (Fe) extraction from solid-phase, calcium ions, Fe total, manganese (Mn) total (ICP-OES), sulfate (ion chromatography, IC), total alkalinity, hydrogen sulfide and nutrients from porewaters as well as sulfate reduction rates. Bottom water chemistry on top of the sediment core was monitored via optical oxygen sensors, alkalinity was titrated, calcium ion concentrations determined over time and dinitrogen was measured at the end of the experiments. High resolution electrochemical microprofiles resolved vertical gradients of sulfide, oxygen, pH and redox across the sediment-water interface. These datasets enable assessments of calcite dissolution, alkalinity generation and microbial responses to enhanced benthic weathering in seasonally hypoxic Baltic Sea sediments.

Kiel Bight sediment core liner water-column data from sediment core incubation experiment in 2025

This dataset consists of water chemistry from within three calcite amended and three reference sediment cores from Kiel Bight from February 2025. Dissolved oxygen was monitored non-invasively using optical sensor spots (OXSP5, PyroScience) at 5cm above the sediment. Total alkalinity and calcium ion concentration were measured at regular intervals over four weeks, covering sediment settlement, calcite amendment, deoxygenation and reoxygenated phases. Water exchanges with nitrogen (N2) deoxygenated seawater-maintained calcite dissolution and N2 was determined at the end of the experiment. The dataset enables reconstruction of alkalinity generation, calcium release and oxygen dynamics during enhanced benthic weathering. This is supporting the assessments of carbon dioxide removal (CDR) efficiency and benthic dynamics.

Dissolved rare earth elements, shale-normalized patterns, biogeochemical parameters, and indices from molecular analysis of dissolved organic matter across the land-ocean continuum in the German Bight

We analyzed concentrations of dissolved rare earth elements (REE) across the land-ocean continuum in the German Bight (southern North Sea) to identify key drivers for REE cycling in dynamic coastal environments. We identified the coastal transition zone as a critical interface for altering predominantly riverine-derived natural and anthropogenic REEs. We combined shale-normalized REE patterns, measured by quadrupole inductively coupled plasma-mass spectrometry (Q-ICP-MS), with biogeochemical bulk parameters and molecular analysis of dissolved organic matter (DOM) determined by ultrahigh-resolution mass spectrometry (FT-ICR-MS). Samples were acquired during RV Heincke cruise HE527. The dataset includes spatially resolved biogeochemical data (concentrations of chlorophyll-a, dissolved nitrogen, dissolved organic carbon, suspended particulate matter, dissolved iron, dissolved manganese and dissolved REE) in surface waters obtained along the major estuarine transects (Ems, Weser, and Elbe), coast-orthogonal transects and an offshore North Sea transect, with additional deep-water samples. Temporally resolved data were collected near the barrier islands Langeoog and Spiekeroog including the Otzumer Balje inlet. The dataset also contains molecular indices based on DOM composition (see Speidel et al., 2024) REE subgroups, ratios and concentrations of anthropogenic Samarium and Gadolinium (for details see Mori et al., 2025).
