This dataset presents data collected along a transect sampled on two dates (6th and 9th of July 2019) on the reef flat of Surprise Island in the D'entrecasteaux Reefs, from land...

This set of suspended matter (SPM) samples and water samples were collected in the South China Sea on the cruise of R/V SONNE 269 between August 5th and 31st 2019. The aim of...

Geographic information, surface mass balance (SMB) data, and sub-photic zone (>0.3 m) nitrate concentration and nitrogen isotopic composition (δ15NNO3) for 135 sites across...

In oceans, estuaries, and rivers, nitrification is an important nitrate source, and stable isotopes of nitrate are often used to investigate recycling processes (e.g....

The Amazon River is known as a region of intense biochemical reactivity. As a result of increased anthropogenic impacts in its catchment (e.g. population growth, agriculture,...

We investigated the microbial nitrogen cycle in the water column of the meromictic Lake Lugano North Basin, Switzerland, during 12 sampling campaigns between 2015 and 2018. At...

This dataset reports greenhouse gas production measurements from a laboratory incubation of sphagnum and peat sourced from a boreal peatland complex (Siikaneva Bog, Finland)....

The Time Series Station Spiekeroog (TSS) was set up in 2002 in the tidal inlet between the East Frisian islands of Langeoog and Spiekeroog in the southern German Bight at...

These water and pore water samples were collected in different oceanic areas between 2013 and 2016. The samples were compiled from previous studies and used for statistical...

Sediment pore water nutrient chemistry on surface sediments from the South Pacific Gyre. Pore waters were obtained by Rhizone sampling of sub-cores from box-cores retrieved...

The impurity and stable isotope in water records extracted from the Colle Gnieffti ice core (Swiss-Italian Alps, 45°55′50″N, 7°52′33″E, 4455 m asl) contain information on the...

A continuous ice core analytical system was used to analyze the ~410 m NEEM-2011-S1 ice core collected in summer 2011 near the NEEM deep drilling site in NW Greenland. The core...

The database for nitrate concentrations and nitrate δ15N includes new data and most of the measurements that have been published to date. This database also includes most of the...

15N nitrate uptake assays were conducted using tracer additions of highly enriched (98%) 15N-labeled nitrate for four Arctic-adapted strains of Thalassiosira gravida and three...

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...
