Compilation of radionuclides, mercury contaminations, and ln(Zr/Rb) ratios, together with mean grain size and organic carbon data records, obtained from sediment sequences of the south-eastern North Sea region, supplement to: Bunzel, Dorothea; Milker, Yvonne; Müller-Navarra, Katharina; Arz, Helge Wolfgang; Friedrich, Jana; Lahajnar, Niko; Schmiedl, Gerhard (2020): Integrated stratigraphy of foreland salt-marsh sediments of the south-eastern North Sea region. Newsletters on Stratigraphy

Dorothea Bunzel, Yvonne Milker, Katharina Müller-Navarra, Helge Wolfgang Arz, Jana Friedrich, Niko Lahajnar & Gerhard Schmiedl
Depositional processes in coastal wetlands respond to a changing climate as documented in the sediment successions of salt marshes. In this context, robust chronologies are crucial for the reconstruction of salt-marsh depositional processes in the past. However, salt-marsh sediments from the highly dynamic North Sea coast often lack a reliable stratigraphy due to the combined influences of natural processes and human activities, causing a reworking and re-deposition of the sediments. Here, a combination of absolute...

Beach Profile Data for the Elwha River Delta, 2011-2018

Ian Miller
Data were collected using GNSS survey methods, with a differential GPS operating in Real Time Kinematic (RTK) mode. Data from prior to 2013 were typically collected with a Magellan ProMark 3 traditional RKT-DGPS system (i.e. local base station and rover), with the base station sited on survey control markers installed in 1996, with survey control coordinates referenced to NAD83(CORS91). Starting in 2013 survey data were typically collected with an AshTech ProMark 200 RTK-DGPS system connected...

Geophysical Research Letters

Bernhard Aichner, Zafar Makhmudov, Ilhomjon Rajabov, Qiong Zhang, Francesco S R Pausata, Martin Werner, Liv Heinecke, Marie L Kuessner, Sarah J Feakins, Dirk Sachse & Steffen Mischke
The Central Asian Pamir Mountains (Pamirs) are a high-altitude region sensitive to climatic change, with only few paleoclimatic records available. To examine glacial-interglacial hydrological changes in the region, we analysed geochemical parameters of a 31-kyrs record from Lake Karakul and performed a set of experiments with climate models to interpret the results. δD values of terrestrial biomarkers showed distinct insolation driven trends reflecting major shifts of water vapor sources. For aquatic biomarkers, positive δD shifts...

2600 years of stratospheric volcanism reconstruction through sulfate isotopes for Antarctic ice cores

Elsa Gautier, Joël Savarino & James Farquhar
We present a 2600 year chronology of stratospheric volcanic events using isotopic signatures (Δ33S and in some cases Δ17O) of ice core sulfate. Five closely-located ice cores from Dome C, Antarctica, are used to reconstruct a record that differs subtly from recent reconstructions calibrated using synchronous volcanic sulfate deposition in Greenland and Antarctica to identify eruptions with global-scale sulfate distribution. Comparing the Dome C stratospheric reconstruction shows good agreement with the recent parts of these...

Carbon, nitrogen, and fatty acid contents for the diatom Conticribra weissflogii and for the larvae of the polychaete Lanice conchilega, supplement to: Franco-Santos, Rita Melo; Auel, Holger; Boersma, Maarten; De Troch, Marleen; Graeve, Martin; Meunier, Cédric Léo; Niehoff, Barbara (2019): You are not always what you eat—Fatty acid bioconversion and lipid homeostasis in the larvae of the sand mason worm Lanice conchilega. PLoS ONE, 14(6), e0218015

Rita Melo Franco-Santos, Holger Auel, Maarten Boersma, Marleen De Troch, Martin Graeve, Cédric Léo Meunier & Barbara Niehoff
The larvae of the reef-building polychaete Lanice conchilega can make up to 15% of the summer zooplankton biomass in the North Sea. Despite their importance for reef maintenance (which positively affects the benthic community), little is known about the trophic ecology of this meroplanktonic larva. Qualitative and quantitative estimates of carbon (C) transfer between trophic levels and of fatty acid (FA)-specific assimilation, biosynthesis, and bioconversion can be obtained by compound-specific stable isotope analysis of FA....

In Situ Growth and Bioerosion Rates of Lophelia pertusa in a Norwegian Fjord and Open Shelf Cold-water Coral Habitat, supplement to: Büscher, Janina; Wisshak, Max; Form, Armin; Titschack, Jürgen; Nachtigall, Kerstin; Riebesell, Ulf (2019): In situ growth and bioerosion rates of Lophelia pertusa in a Norwegian fjord and open shelf cold-water coral habitat. PeerJ, 7, e7586

Janina Büscher, Max Wisshak, Armin Form, Jürgen Titschack, Kerstin Nachtigall & Ulf Riebesell
Coral reef resilience depends on the balance between carbonate precipitation, leading to reef growth, and carbonate degradation, e.g. through bioerosion. Changes in environmental conditions are likely to affect the two processes differently, thereby shifting the balance between reef growth and degradation. In cold-water corals estimates of accretion-erosion processes in their natural habitat are scarce and solely live coral growth rates were studied with regard to future environmental changes in the laboratory so far, limiting our...

Effects of elevated CO2 on a natural diatom community in the subtropical North East Atlantic, supplement to: Bach, Lennart Thomas; Hernández-Hernández, Nauzet; Taucher, Jan; Spisla, Carsten; Sforna, Claudia; Riebesell, Ulf; Arístegui, Javier (2019): Effects of Elevated CO2 on a Natural Diatom Community in the Subtropical NE Atlantic. Frontiers in Marine Science, 6

Lennart Thomas Bach, Nauzet Hernández-Hernández, Jan Taucher, Carsten Spisla, Claudia Sforna, Ulf Riebesell & Javier Arístegui
Diatoms are silicifying phytoplankton contributing about one quarter to primary 79production on Earth. Ocean acidification (OA) could alter the competitiveness of diatoms 80relative to other taxa and/or lead to shifts among diatom species. In spring 2016, we set 81up a plankton community experiment at the coast of Gran Canaria (Canary Islands, 82Spain) to investigate the response of subtropical diatom assemblages to elevated 83 84seawater pCO2.

UAV-based methane data from Barter Island, Northern Alaska, September 2017, supplement to: Oberle, Ferdinand K; Gibbs, Ann E; Richmond, Bruce M; Erikson, Li H; Waldrop, Mark P; Swarzenski, Peter W (2019): Towards determining spatial methane distribution on Arctic permafrost bluffs with an unmanned aerial system. SN Applied Sciences, 1(236)

Ferdinand K Oberle
Arctic permafrost stores vast amounts of methane (CH4) in subsurface reservoirs. Thawing permafrost creates areas for this potent greenhouse gas to be released to the atmosphere. Identifying 'hot spots' of methane flux on a local scale has been limited by the spatial scales of traditional ground-based or satellite-based methane-sampling methods. Here we present methane data from along the coast of Barter Island, Alaska that was produced with an Unmanned Aerial System and an off-the-shelf, cost-effective...

Reflectance measurements of different surface types from Arctic sea ice acquired during POLARSTERN cruise PS106, supplement to: König, Marcel; Hieronymi, Martin; Oppelt, Natascha (2019): Application of Sentinel-2 MSI in Arctic Research: Evaluating the Performance of Atmospheric Correction Approaches Over Arctic Sea Ice. Frontiers in Earth Science, 7

Marcel König, Martin Hieronymi & Natascha Oppelt
Some of the spectra have a timestamp, sometimes only the measurement has a timestamp. The locations of the measurements have been mapped with three different GPS devices. In some of the data sets, every measurements can be localized with a GPS position by joining the GPS data with the spectral data on the datetime of the measurement but for some data sets, GPS positions have been acquired after the spectral measurements. For these data sets,...

N2O, CH4 and CO2 fluxes from automated and manual chamber measurements at the Kaserstatt Alm subalpine site, Austria, supplement to: Harris, Eliza; Ladreiter-Knauss, Thomas; Butterbach-Bahl, Klaus; Wolf, Benjamin; Bahn, Michael (2018): Land-use and abandonment alters methane and nitrous oxide fluxes in mountain grasslands. Science of the Total Environment, 628-629, 997-1008

Eliza Harris, Thomas Ladreiter-Knauss, Klaus Butterbach-Bahl, Benjamin Wolf & Michael Bahn
Article abstract: Grasslands cover more than one fifth of total land area in Europe and contribute significantly to the total greenhouse gas budget. The impact of management and land use on the carbon cycle and carbon sequestration in grasslands has been well-studied, however effects on emissions of N2O and CH4 remain uncertain. Additionally, the majority of studies have focussed on management differences between intensively managed grasslands, with few results available for lightly managed grasslands and...
