Dissolved methane concentration and diffusive flux near Sylt, North Sea in su...

In July 2023 a cruise with RV Mya_II took place to investigate if the dredging of sand off Sylt influences the atmospheric and dissolved methane concentrations. With the ship's...

Methane concentration and diffusive flux in the Northern Sea off Heligoland i...

As part of the MOSES Project, in April 2023 methane measurements were started in the north-western part of the island Heligoland in the German Bight (North Sea). The objective...

Greenhouse gases in the River Elbe, 2020-2024

Measurements of dissovled greenhouse gases (GHG) being CO2, CH4 and N2O were performed from 2020 until 2024. Water samples were taken from bridges at tow locations at the river...

Methane concentration and its isotopic composition in seawater during POLARST...

The methane concentration and stable carbon isotopic signature of methane were measured in different Arctic sea ice types as well as in seawater underneath the ice floe during...

Biogeochemical data during RV POLARSTERN cruise PS109

The concentration and carbon isotope delta (δ13C) of methane (CH4), the water mass tracer δ18O(H2O), and nutrient concentrations were measured in seawater during the Polarstern...

Dissolved concentrations of CH4, nutrients, and biological parameters in the ...

We sampled twice 12 reservoirs between July 2016 and August 2017 in southern Spain during the summer stratification and the winter mixing. We determined reservoir area,...

Sea surface trace gases during Maria S. Merian cruise MSM105

The high surface productivity triggered by nutrient-rich Benguela upwelled waters results in significant enrichment of organic carbon in the sub-surface waters due to enhanced...
