Sedimentation rates and mass accumulation rates of sediment and dust in Europe and China

Denis-Didier Rousseau, Pierre Antoine & Youbin Sun
Loess sequences are a particular record of paleoenvironments and paleoclimates and show regional peculiarities. Among those, European loess sequences show the occurrence of paleosols and other pedogenic units that have been demonstrated to correspond to the Greenland Interstadials (GIS) or Dansgaard-Oeschger events (DO), for the last climate cycle (Moine et al. 2017), of GIS-like for the penultimate climate cycle (Rousseau et al. 2020).During the last climate cycle, these paleosols developed synchronously over Europe along a...

Effect and fate study with blue mussels and microplastic in a laboratory experiment

Aurelia Laubscher, Thea Hamm & Mark Lenz
Adult blue mussels (Mytilus spp.) were exposed to microplastic particles in a controlled laboratory experiment. The study was conducted to investigate I) the effect of polystyrene particles (spherical PS beads, 40µm) on the filtration of mussels and II) the fate of PS beads within the experimental set up. The data was obtained in May and June 2019 with mussels collected from the Kiel Fjord, Germany. The mussels were exposed in a closed system to an...

Porewater geochemistry of two shallow-water hydrothermal vents off Dominica Island (Lesser Antilles), supplement to: Pop Ristova, Petra; Pichler, Thomas; Friedrich, Michael W; Bühring, Solveig I (2017): Bacterial diversity and biogeochemistry of two marine shallow-water hydrothermal systems off Dominica (Lesser Antilles). Frontiers in Microbiology, 8

Petra Pop Ristova, Thomas Pichler, Michael W Friedrich & Solveig I Bühring
Shallow-water hydrothermal systems represent extreme environments with unique biogeochemistry and high biological productivity, at which autotrophic microorganisms use both light and chemical energy for the production of biomass. Microbial communities of these ecosystems are metabolically diverse and possess the capacity to transform a large range of chemical compounds. Yet, little is known about their diversity or factors shaping their structure or how they compare to coastal sediments not impacted by hydrothermalism. To this end, we...

Vegetation surveys from the calcareous grassland of the nature reserve Garchinger Heide

Markus Bauer & Harald Albrecht
This dataset contains the vegetation surveys from a monitoring of the calcareous grassland of the nature reserve 'Garchinger Heide'. These surveys should discover species composition changes in the second-oldest nature reserve of Bavaria. Two different studies were resurveyed in 2018. The first dataset is based on plots of Briemle (1973), was first surveyed in 40 plots in 1984 (Pfadenhauer & Liebermann 1986) and resurveyed in 1993 (Höngdobler 1995). The second dataset of 42 different plots...

Meteorological data Weißseespitze/Austria, 2017 et seq

Martin Stocker-Waldhuber, Bernd Seiser & Andrea Fischer
The meteorological data were recorded at Weißseespitze (3500 m) in the Ötztal Alps/Austria during the FWF project Cold Ice, P 29256-N36. This is the raw data as recorded, without quality control and without error corrections. Please be aware that before using the data the quality control is a necessary step before using the data in a scientific context. For example, at this high elevation site the albedo values recorded together with the radiation components contain...

Phytoplankton species composition under Fe and Mn limitation in the Drake Passage

Jenna Balaguer, Florian Koch, Christel S Hassler & Scarlett Trimborn
This study highlights the importance of manganese (Mn) next to iron (Fe) for growth of specific Southern Ocean phytoplankton groups. Two Fe-Mn bottle amendment experiments with two natural phytoplankton communities were performed during Polarstern expedition PS97 in 2016 in the Drake Passage. At two locations, sea water was pumped (using trace metals clean techniques) from 25m depth and used to fill polycarbonate bottles after having passed through a cleaned 200 μm mesh (removing large grazers)....

Kirstin Hoffmann-Abdi, Francisco Fernandoy, Hanno Meyer, Johannes Freitag, Thomas Opel, Joseph R McConnell & Christoph Schneider
The firn core OH-12 was retrieved from Plateau Laclavere, a small ice cap on the northernmost end of the Antarctic Peninsula at about 1090 m above sea level in January 2016. The core was drilled down to 19.93 m depth. Subsamples for stable water isotope analysis were obtained from the core at 5 cm resolution. Stable water isotope measurements were performed in autumn 2016 using cavity ring-down spectrometers L2130-i and L2140-i (Picarro Inc.) coupled to...

Marwa Baloza, Susann Henkel, Walter Geibert, Sabine Kasten & Moritz Holtappels
During the PS118 research cruise with the German research vessel RV POLARSTERN (Feb 2019- April 2019), sediments were collected with a multicorer from 7 stations along a 400 mile transect from the eastern shelf of the Antarctic Peninsula to the West of the South Orkney Islands. A total of 69 high-resolution O2 profiles were measured in 23 cores in the upper sediment layer using optical microsensors (Optodes, Pyroscience) in order to determine oxygen penetration depths...

Mg/Ca temperature, d18O data, Sr/Ca ratio and radiocarbon ages from sediment core GeoB18530-1 in the western subpolar North Atlantic

Lars Max, Dirk Nürnberg, Cristiano Mazur Chiessi, Marlene M Lenz & Stefan Mulitza
Sediment core GeoB18530-1 was collected during MSM39 cruise in 2014 in the subpolar western North Atlantic. X-ray fluorescence (XRF) core-scanning measurements of GeoB18530-1 were performed with an Avaatech XRF Core Scanner at the MARUM - University of Bremen. For Mg/Ca analyses, ~100 individuals of the foraminiferal species N. pachyderma sin. were picked from sieved sediment samples of the size fraction >250 μm. Mg/Ca analyses were performed with an axial-viewing ICP-OES Varian 720 ES (Inductively Coupled...

Christoph Leitner, Franz Neubauer, Johann Genser & Manfred Bernroider
To test polyhalite age dating of the mineral polyhalite [K2Ca2Mg(SO4)4·2H2O], samples of the evaporitic Permian Haselgebirge Formation were collected in the Eastern Alps. Samples were taken from two salt bodies. The salt body of Altaussee (UTM 33T 405316 5278325) has a vertical thickness of >800 m. Samples were collected in the Altaussee mine (ALT). The salt body of Bad Dürrnberg-Berchtesgaden (UTM 33T 351091 5278007) is at least 1000 m thick. The salt body comprises two...
