Carbon and nitrogen isotopic composition of Early Toarcian sediments, supplement to: Jenkyns, Hugh C; Gröcke, Darren R; Hesselbo, Stephen P (2001): Nitrogen isotope evidence for water mass denitrification during the Early Toarcian (Jurassic) oceanic anoxic event. Paleoceanography, 16(6), 593-603

Hugh C Jenkyns, Darren R Gröcke & Stephen P Hesselbo
Bulk sedimentary nitrogen isotope (d15Ntot) data have been generated from Lower Jurassic black, carbon-rich shales in the British Isles and northern Italy deposited during the early Toarcian oceanic anoxic event. A pronounced positive d15Ntot excursion through the exaratum Subzone of the falciferum Zone (defined by characteristic ammonites in the British Isles) broadly correlates with a relative maximum in weight percent total organic carbon and, in some sections, with a negative d13Corg excursion. Upwelling of a...

Snow melt monitoring near the Polish Polar Station in Hornsund, Svalbard, using Automatic Camera Systems

Bartłomiej Luks, Tomasz Wawrzyniak & Sebastian Westermann
On Svalbard, the long-lasting snow cover and the timing of the snowmelt is a crucial factor in the yearly cycle of all land ecosystems. To monitor the timing and patterns of snow melt, automatic camera systems have been set up at two locations overlooking key research areas near the Polish Polar Station in Hornsund, Svalbard. All images are provided in daily resolution, and the date coded in the filename as yyyy-MM-dd.This work was funded by...

Shipborne ocean color remote sensing, supplement to: Garaba, Shungudzemwoyo Pascal; Voß, Daniela; Wollschläger, Jochen; Zielinski, Oliver (2015): Modern approaches to shipborne ocean color remote sensing. Applied Optics, 54(12), 3602-3612

Shungudzemwoyo Pascal Garaba, Daniela Voß, Jochen Wollschläger & Oliver Zielinski
In this paper, modernized shipborne procedures are presented to collect and process above-water radiometry for remote sensing applications. A setup of five radiometers and a bidirectional camera system, which provides panoramic sea surface and sky images, is proposed for the collection of high-resolution radiometric quantities. Images from the camera system can be used to determine sky state and potential glint, whitecaps, or foam contamination. A peak in the observed remote sensing reflectance RRS spectra between...

Microcharcoal concentration and elongation, and age model of sediment core MD96-2098, supplement to: Daniau, Anne-Laure; Sanchez Goñi, Maria Fernanda; Martinez, Philippe; Urrego, Dunia H; Bout-Roumazeilles, Viviane; Desprat, Stéphanie; Marlon, Jennifer R (2013): Orbital-scale climate forcing of grassland burning in southern Africa. Proceedings of the National Academy of Sciences, 110(13), 5069-5073

Although grassland and savanna occupy only a quarter of the world's vegetation, burning in these ecosystems accounts for roughly half the global carbon emissions from fire. However, the processes that govern changes in grassland burning are poorly understood, particularly on time scales beyond satellite records. We analyzed microcharcoal, sediments, and geochemistry in a high-resolution marine sediment core off Namibia to identify the processes that have controlled biomass burning in southern African grassland ecosystems under large,...

Upper air soundings during POLARSTERN cruise ARK-XXIV/2

Gert König-Langlo
The upper air soundings are normally performed once a day to measure vertical profiles of air pressure, temperature, relative humidity and the wind vector. Helium filled balloons (TOTEX 600 g, 800 g) were used to carry Vaisala RS92-SGPW radiosondes. Whenever possible, the launches were performed about 10 UTC. Condensed measurements (TEMP Format FM-35) were transferred without delay into the Global Telecommunication System GTS were they contribute for the world wide weather forecasts. The profile data...

Chemical characterization of dissolved organic compounds from coastal sea surface microlayers (Baltic Sea, Germany), supplement to: van Pinxteren, Manuela; Müller, Conny; Iinuma, Yoshiteru; Stolle, Christian; Herrmann, Hartmut (2012): Chemical characterization of dissolved organic compounds from coastal sea surface microlayers (Baltic Sea, Germany). Environmental Science & Technology, 46(19), 10455-10462

Manuela van Pinxteren, Conny Müller, Yoshiteru Iinuma, Christian Stolle & Hartmut Herrmann
The physicochemical properties of the sea surface microlayer (SML), i.e. the boundary layer between the air and the sea, and its impact on air-sea exchange processes have been investigated for decades. However, a detailed description about these processes remains incomplete. In order to obtain a better chemical characterization of the SML, in a case study three pairs of SML and corresponding bulk water samples were taken in the southern Baltic Sea. The samples were analyzed...

Ichthyolith (tooth and denticle) counts from DSDP 386, 596, ODP 886, 1262, IODP U1403, and Gubbio K/Pg boundary sections, supplement to: Sibert, Elizabeth C; Norris, Richard D (2015): New Age of Fishes initiated by the Cretaceous-Paleogene mass extinction. Proceedings of the National Academy of Sciences, 112(28), 8537-8542

Elizabeth C Sibert & Richard D Norris
Ray-finned fishes (Actinopterygii) comprise nearly half of all modern vertebrate diversity, and are an ecologically and numerically dominant megafauna in most aquatic environments. Crown teleost fishes diversified relatively recently, during the Late Cretaceous and early Paleogene, although the exact timing and cause of their radiation and rise to ecological dominance is poorly constrained. Here we use microfossil teeth and shark dermal scales (ichthyoliths) preserved in deep-sea sediments to study the changes in pelagic fish community...

Deep Sea Research Part II: Topical Studies in Oceanography, 55(8-9), 1000-1014

Rainer Kiko, Jan Michels, Elke Mizdalski, Sigrid B Schnack-Schiel & Iris Werner
The surface and sub-ice layer habitats and their metazoan fauna were studied on a drifting pack-ice floe in the western Weddell Sea from 29 November 2004 to 1 January 2005 during the "Ice Station POLarstern" (ISPOL). Flooding of the floe occurred at some places, and the establishment of surface layers with a brownish colour due to growing algae was observed at several sampling sites. The average surface-layer temperature, brine salinity and brine volume were -1.4...

Foraminiferal assemblage and statistical analysis of surface sediment samples from the Golfe d'Arguin, Mauritania, supplement to: Reymond, Claire E; Mateu-Vicens, G; Westphal, Hildegard (2014): Foraminiferal assemblages from a transitional tropical upwelling zone in the Golfe d'Arguin, Mauritania. Estuarine, Coastal and Shelf Science, 148, 70-84

Claire E Reymond, G Mateu-Vicens & Hildegard Westphal
With the growing pressure of eutrophication in tropical regions, the Mauritian shelf provides a natural situation to understand the variability in mesotrophic assemblages. Site-specific dynamics occur throughout the 1200 m depth gradient. The shallow assemblages divide into three types of warm-water mesotrophic foraminiferal assemblages, which is not only a consequence of high primary productivity restricting light to the benthos but due to low pore water oxygenation, shelf geomorphology, and sediment partitioning. In the intermediate depth...
