Here we present a fully quality controlled macro-nutrient data set from analyses carried out onboard the RV Polarstern during the expedition PS131 ATlantic WAter pathways to the...

This dataset supports the publication "Dry-to-flow mode: impacts on river carbon and nitrogen dynamics". In where we investigated how instant and gradual surface flow resumption...

The water column was profiled for nutrients (nitrate, nitrite, phosphate, ammonium, silicate), gases (hydrogen sulfide, dihydrogen, oxygen), and pH during pump-CTD casts aboard...

The discrete biogeochemical measurements from RV Akademik Tryoshnikov AT21 sampled for chlorophylla, delta 18O isotopes, dissolved organic matter and microbial cell abundances....

This data is part of the BMBF projects CUSCO (Coastal Upwelling Systems in a Changing Ocean) and BioTip subproject Humboldt Tipping. Data was collected during cruise number...

Pore water dissolved organic carbon (DOC) and inorganic nutrients were collected by Rhizon samplers from the water 2 cm above the sediment and the top 10 cm of the sediment...

The Guaymas Basin hydrothermal vents in the Gulf of California have been visited during RV Atlantis mission AT37-06 in December 2016. Aim of this mission was to understand...

Ocean acidity has increased by 30% since preindustrial times due to the uptake of anthropogenic CO2 and is projected to rise by another 120% before 2100 if CO2 emissions...

The response of the coccolithophore Emiliania huxleyi to rising CO2 concentrations is well documented for acclimated cultures where cells are exposed to the CO2 treatments for...

The surface ocean absorbs large quantities of the CO2 emitted to the atmosphere from human activities. As this CO2 dissolves in seawater, it reacts to form carbonic acid. While...

Diazotrophic (N2-fixing) cyanobacteria provide the biological source of new nitrogen for large parts of the ocean. However, little is known about their sensitivity to global...

Rewetting peatlands is an important measure to reduce greenhouse gas (GHG) emissions. However, after rewetting, the areas are highly heterogeneous in terms of GHG exchange,...

We investigated Polyphosphate (polyP) cycling in a cross-latitudinal section (15°N-39°N, 150°E) of the Northwest Pacific Ocean, covering a diverse nutrient gradient and varying...

Here, we report on both photic and aphotic primary productivity, dark carbon fixation and heterotrophic bacterial production rates from 6 cruises conducted in 2021-2023 at the...

Surface water samples of the river Elbe were taken in May 2021 with the vessel Zwergseeschwalbe between Geesthacht and Neu Darchau. Connecting cruises were performed from...

This dataset includes downcore measurements of dissolved inorganic carbon (DIC) and its stable carbon isotopic composition (δ13C-DIC) for sediment cores retrieved using...

The Guaymas Basin hydrothermal vents in the Gulf of California (Mexico) were visited with the research vessel RV Atlantis in November to December 2018 (mission AT 42-05). Due to...

Coastal ecosystems are heterogeneous environments with high turnover rates of carbon and nutrients that influence the distribution of greenhouse gases (GHG). They also represent...

To study how the biogeochemical Si cycle in large river estuary and coastal areas has responded to one of the largest river regulation projects in the world, we conducted four...

In addition to data collection by the logger units, nutrients are measured at 23 locations. Sampling occurs every 14 days at each site. Samples are taken from a water depth of...
