Moses Sternfahrt-9, Chemical transformation of chlorophyll-a and dissolved or...
As the previous cruises were mainly conducted in August / September, this cruise was set up to cover a late spring situation in the German Bight. The cruise track and positions... -
Simulation of greenhouse gas production during key transitions in a coastal t...
The dataset presents the greenhouse gas production (CO2 and CH4) from sediment of a terrestrial permafrost outcrop (Byk14-A-1; 71.85175°N, 129.350883°E), the thermokarst lake... -
Carbon compounds, methane concentration and nutritional composition of water ...
The "Sternfahrt 9" cruise was conducted from the 30th of May to the 2nd of June 2022, covering a late spring situation in the German Bight. The three participating vessels... -
Modeled timing of flooding for the Beringian shelf for the past 20,000 years
The paleo bathymetry grids (PaleoMIST 1.0 (Gowan et al. 2021) were used to calculate the timing of flooding in the Beringia study region. The resulting GeoTiff (Year of... -
Methane concentration and oxidation rate in the Yangtze River Estuary (July 2...
We investigated the dynamic of methane (CH4) concentration, saturation, and sea-to-air flux in the typical near-shore (Yangtze River Estuary) and outer shelf (East China Sea)... -
Methane dry air mole fractions measured during MOSAiC 2019/2020 (merged dataset)
This dataset contains hourly-averaged methane dry air mole fractions measured during the year-long Multidisciplinary drifting Observatory for the Study of Arctic Climate... -
Methane dry air mole fractions measured in the Swiss container during MOSAiC ...
This dataset contains minute-averaged methane dry air mole fractions measured during the year-long Multidisciplinary drifting Observatory for the Study of Arctic Climate... -
CH4 Aircraft Vertical Profiles Measurements at Four Amazonian Sites Between 2...
To improve diagnosis of Amazonia's carbon cycle, starting in 2010, we initiated regular observation of lower troposphere CH4 concentrations at four aircraft vertical profiling... -
Cumulative greenhouse gas production in thawed sediments underneath a Yedoma ...
This dataset describes two 17 m long sediment cores taken from beneath two thermokarst lakes in the Yukechi Alas, Central Yakutia, Russia. The first core was taken from below an... -
Dissolved-gas concentrations, physical and chemical properties of 41 ponds as...
Ponds emit more methane per area than larger lakes. However, methane concentrations in and methane emissions from ponds show more spatial variability than larger waterbodies. A... -
Column-averaged dry-air mole fractions of CO2, CH4 and CO recorded during an ...
In August 2018, we deployed five solar-tracking Fourier transform spectrometers (EM27/SUN) in the urban area of Munich to measure the column-averaged dry-air mole fraction of... -
Geochemical data from batch experiments simulating hydrothermal troctolite al...
Troctolites represent a close analogue to komatiites, a type of rock assumed to have been common on ancient earth and thus associated water-rock reactions likely have been... -
Stem and soil methane flux measurements and environmental observations in a d...
During the WETSCAPES Project (ESF/14-BM-A55-0034/16 and ESF/14-BM-A55-0030/16) stem and soil fluxes were measured at two temperate alder forests in north-eastern Germany.... -
CH4 concentrations in the culture system during long-term culture of Gigantid...
The seawater in the G. childressi culture system was enriched with methane by injection of methane-enriched air from an air-methane gas mixing device. methane concentrations... -
Valve gape activity of cultured Gigantidas childresse: mean data
Valve gape activity of cultured G. childressi mussels from different nutritional treatments (CH4: 'M', algae + CH4: 'MA', algae: 'A') at changing seawater CH4 concentrations.... -
Gas consumption of cultures Gigantidas childressi
Gas consumption of two batches (1 and 2) of cultured G. childressi. Batch 2 mussels were cultured under 3 different nutrition regimes (CH4, algae + CH4, only algae). Methane... -
Methane concentrations in seawater at different air CH4 levels in deep-sea mu...
Daily averages of measured CH4 concentrations in our recirculating aquarium system at six different CH4 levels (%) in the air used to equilibrate the seawater. -
Methane concentrations in deep-sea mussel culture: hand feed
During culture of deep-sea mussels Bathymodiolus azoricus in November 2013, the culture system (200 L) was repetitively enriched with methane by adding 5 L CH4-saturated sea... -
Methane concentrations in deep-sea mussel culture: continuous methane feeding
During culture of deep-sea mussels Gigantidas Childressi in September 2017, the culture system (200 L) was continuous enriched with methane by bubbling with methane-enriched air... -
