The amount of Fe sequentially extracted from sediments of site S1, S2 and S3 over microbial incubation without or with the amendment of Na-molybdate.

We studied dissolved organic matter (DOM) dynamics in the sea surface microlayer (SML) during a multidisciplinary mesocosm study at the Sea sURface Facility (SURF) of the...

A spring bloom of algae in or underneath sea ice provides a concentrated food source for aquatic grazers and contributes significantly to marine primary production in many...

This datasheet includes radiocarbon and thermogravimetric analysis (TGA) results of permafrost leachate from samples collected in the Lena Delta. The leaching protocol followed...

Six mesocosm experiments with specimens of Fucales or Laminariales were conducted across six georegions (3 mesocosms with brown algae, 3 mesocosms without brown algae)....

The water sampling was performed using a CTD Rosette system, consisting of 12 L Niskin bottles. The samples were filtered using a 0.7 μm Whatman GF/F syringe filter (filter was...

The data were collected from an experiment using phytoplankton cultures (Apocalathium malmogiense and Rhodomonas marina). The aim of the experiment was to study carbon cycling...

In order to explore past vegetation and hydroclimatic changes in the eastern region of northeastern Brazil over the late Pleistocene, we present the long-chain n-alkanes...

This dataset comprises dissolved organic carbon (DOC) concentrations from axenic and xenic cultures of Thalassiosira gravida that were cultivated at the Alfred-Wegener-Institute...

Hydrographic, biogeochemical, and dissolved organic matter (DOM) molecular data were collected during the R/V SONNE expedition SO305/2 (16 July - 6 August 2024) along a transect...

In March 2024, sediment cores were collected along two land-ocean transects along the coast of the Baldwin Peninsula (Alaska). Undisturbed permafrost upland, thermokarst lake,...

In this dataset, we present the initial soil parameters of two cores from a palsa and a peatland in Lapland, as well as hydro-chemical parameters of thermokarst water used for...

The data set contains chamber measurements of methane (CH4) emissions from vegetation removal experiments consisting of three vegetation treatments (intact vegetation, vascular...

In August and September 2022, a sediment sampling and site investigation program was conducted near Ny-Ålesund on Svalbard. With the Bayelva Observatory having monitored...

The present dataset contains environmental variables: temperature, salinity, fluorescence, turbidity, nitrite, nitrate, phosphate, silicon dioxide, total alkalinity, dissolved...

This dataset includes elemental and isotopic data, environmental parameters, and fractional abundances of branched glycerol dialkyl glycerol tetraethers (brGDGTs) and branched...

The Baltic Sea has been affected by eutrophication for several decades with the result of a gradual increase of oxygen minimum zones at the sea floor and release of phosphate...

The data set contains measurements of methane (CH4) emissions and their δ13C values at vegetation removal experiments consisting of three vegetation treatments (intact...
