Diatom-bound nitrogen isotopes (d15N-db) from the trigger core PS69/899-2TC, located in the Indian sector of the Southern Ocean. This proxy reflects past variations in the...

Diatom-bound nitrogen isotopes (d15N-db) from sediment cores PS69/899-2, located in the Indian sector of the Southern Ocean, covering the past 150,000 years, based on the age...

This dataset includes dual nitrate stable isotope collected at 21 stations of the R/V Sonne cruise SO305 BIOCAT-IIOE2 (10 April – 22 May 2024). Samples were collected at 21...

Concentrations and stable isotopic composition of particulate organic carbon and nitrogen from CTD-rosette casts during the MOSAiC (PS122) drift expedition in the central Arctic...

For stable isotope baseline measurements, the primarily herbivorous copepod Nannocalanus minor was collected during the research cruise SO285 on RV Sonne in the northern (nBUS)...

Squids were collected during the research cruise SO285 on RV Sonne in the northern (nBUS) and southern (sBUS) Benguela Upwelling System between September 13 and October 9, 2021...

Here we examine the effects of CO2 concentrations on the biomass δ15N signatures of the diazotrophs Trichodesmium erythraeum and Crocosphaera watsonii, which utilize Mo‐Fe...

The data are from sediments collected during ODP Expedition 112, borehole 680A, at the Peruvian Margin. The dataset includes concentrations of Al (mg/g), Fe (mg/g), Mn (mg/g), P...

The data contains biogeochemical data, including total carbon and nitrogen concentrations, as well as stable carbon (δ13C) and nitrogen isotopes (δ15N) of 21 samples from the...

In Ischia, Italy, two species of Mediterranean scleractinian corals–the symbiotic Cladocora caespitosa and the asymbiotic Astroides calycularis–were collected from ambient pH...

We conducted a minicosm experiment with pre-acclimated cultures of the globally significant diazotroph Crocosphaera watsonii strain WH8501 ("Crocosphaera"). PH and temperature...

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.),...

We present sediment data from cores collected at bathyal and abyssal depths (1960–5337 m) along a 2400-km North–South transect in the Atlantic part of the Southern Ocean. During...

We measured N and O isotope effects during nitrate assimilation and physiological states of the marine diatom Thalassiosira weissflogii and Synechococcus under different pH (8.1...

Sediment cores and pore water cores were taken in the Skagerrak and North Sea with a multicorer on cruise AL557 (June 2021). The sediment cores were sliced onboard into 1 cm...

This data was collected as a part of a mesocosm study to investigate the ecosystem impacts of ocean alkalinity enhancement, within the EU H2020 OceanNETs project. Nine mesocosms...

Upwelling systems are significant sources of atmospheric nitrous oxide (N₂O). The Benguela Upwelling System is one of the most productive regions worldwide and a temporally...

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

This dataset results from two, month-long global change laboratory experiments conducted in Sitka, Alaska from February 12 to March 18, 2020 (winter experiment) and August 15 to...

The data originates from 23 drilling stations sampled in the Canadian Beaufort Sea in September and October 2021 as part of the PeCaBeau2021 (Permafrost Carbon on the Beaufort...
