Drainage basin delineation for outlet glaciers of Northeast Greenland based on Sentinel-1 ice velocities and TanDEM-X elevations, supplement to: Krieger, Lukas; Floricioiu, Dana; Neckel, Niklas (2020): Drainage basin delineation for outlet glaciers of Northeast Greenland based on Sentinel-1 ice velocities and TanDEM-X elevations. Remote Sensing of Environment, 237, 111483

Lukas Krieger, Dana Floricioiu & Niklas Neckel
The drainage divides of ice sheets separate the overall glaciated area into multiple sectors. These drainage basins are essential for partitioning mass changes of the ice sheet, as they specify the area over which basin specific measurements are integrated. The delineation of drainage basins on ice sheets is challenging due to their gentle slopes accompanied by local terrain disturbances and complex patterns of ice movement. Until now, in Greenland the basins have been mostly delineated...

Microscopic images and 2D-MALDI - images of the sponge Aplysina aerophoba in response to grazing and video recording of grazing behavior

Yu-Chen Wu, María García-Altares, Marta Ribes, Ute Hentschel & Lucía Pita
We aimed to investigate the cellular and chemical response of the chemically defended sponge Aplysina aerophoba (Phylum Porifera: Class Demospongiae) to grazing by its specialist Tylodina perversa (Phylum Mollusca: Class Opistobranchia). Three treatments were applied: control, grazing, and mechanical damage. Samples were collected 3 hours, 1 day, 3 days, and 6 days after treatment. The behavior of sea slugs after directly contact with sponge specimen was recorded by using a GoPro Hero 4 camera with...

Microsensor measurements of oxygen concentration profiles, and computer-simulated concentration profiles of oxygen, ammonium and nitrate oxygen in Trichodesmium colonies, supplement to: Klawonn, Isabell; Eichner, Meri; Wilson, Samuel T; Moradi, Nasrollah; Thamdrup, Bo; Kümmel, Steffen; Gehre, Matthias; Khalili, Arzhang; Grossart, Hans-Peter; Karl, Dave; Ploug, Helle (accepted): Distinct nitrogen cycling and steep chemical gradients in Trichodesmium colonies. The ISME Journal

Isabell Klawonn, Meri Eichner, Samuel T Wilson, Nasrollah Moradi, Bo Thamdrup, Steffen Kümmel, Matthias Gehre, Arzhang Khalili, Hans-Peter Grossart, Dave Karl & Helle Ploug
Trichodesmium is an important dinitrogen (N~2~)-fixing cyanobacterium in marine ecosystems. Recent nucleic acid analyses indicate that Trichodesmium colonies with their diverse epibionts support various nitrogen (N) transformations beyond N~2~-fixation. However, rates of these transformations and concentration gradients of N-compounds in Trichodesmium colonies remain largely unresolved. We combined isotope-tracer incubations, micro-profiling, and numeric modelling to explore carbon fixation, N-cycling processes, as well as oxygen, ammonium and nitrate concentration gradients in individual field-sampled Trichodesmium colonies. Colonies were...

Holocene storminess reconstruction based on aeolian sand Influx measured along core F-02, Filsø, Western Denmark, supplement to: Goslin, Jérôme; Gałka, Mariusz; Sander, Lasse; Mokenbusch, Johannes; Thibault, Nicolas; Clemmensen, Lars B (2019): Decadal variability of north-eastern Atlantic storminess at the mid-Holocene: New inferences from a record of wind-blown sand, western Denmark. Global and Planetary Change, 180, 16-32

Jérôme Goslin, Mariusz Gałka, Lasse Sander, Johannes Mokenbusch, Nicolas Thibault & Lars B Clemmensen
Disentangling the external and internal forcing responsible for the variability of the Earth's climate and associated extreme events over the Holocene is crucial for producing reliable scenarios of adaptation to the effects of ongoing climate change. At mid-latitudes, significant relationships between westerly storminess, solar activity and internal atmospheric and oceanic modes of variability have been repeatedly evidenced to exist over millennial and centennial time scales. However, at shorter (decadal) scale, it is still challenging to...

Reconstructing Late Holocene North Atlantic atmospheric circulation changes using functional paleoclimate networks, supplementary material, supplement to: Franke, Jasper G; Werner, Johannes P; Donner, Reik V (2017): Reconstructing Late Holocene North Atlantic atmospheric circulation changes using functional paleoclimate networks. Climate of the Past, 13(11), 1593-1608

Jasper G Franke, Johannes P Werner & Reik V Donner
Obtaining reliable reconstructions of long-term atmospheric circulation changes in the North Atlantic region presents a persistent challenge to contemporary paleoclimate research, which has been addressed by a multitude of recent studies. In order to contribute a novel methodological aspect to this active field, we apply here evolving functional network analysis, a recently developed tool for studying temporal changes of the spatial co-variability structure of the Earth's climate system, to a set of Late Holocene paleoclimate...

Multichannel reflection seismic data from the Lower Bengal Fan, Profile GeoB97-020-027, supplement to: Bergmann, Fenna; Schwenk, Tilmann; Spieß, Volkhard; France-Lanord, Christian (accepted): Middle to Late Pleistocene Architecture and Stratigraphy of the lower Bengal Fan – Integrating multichannel seismic data and IODP Expedition 354 result. Geochemistry, Geophysics, Geosystems

Fenna Bergmann, Tilmann Schwenk, Volkhard Spieß & Christian France-Lanord
Utilizing a novel dataset of integrated high‐resolution multichannel seismic data with IODP Expedition 354 drilling results, a Middle to Late Pleistocene stratigraphy for the lower Bengal Fan is developed. The study reveals a high lateral and temporal variability of deposition expressed by lateral shifts (often exceeding 100 km) between successive channel‐levee systems (CLSs), which occurred on average every ~15 kyrs independent from sea‐level changes. The CLSs are embedded in sheeted sediments deposited out of unchannelized...
