Analysis of manganese nodules from Lake Baikal, supplement to: Bukharov, A A; Murashko, D N; Fialkov, V A (1993): Ferromanganese nodules on the underwater slopes of the Uskahan Islands, Lake Baykal. International Geology Review, 35(1), 89-100

A A Bukharov, D N Murashko & V A Fialkov
Although ferromanganese crusts from shallow depths in Lake Baykal have been described previously, the presence of nodules at depths of about 500 m are a new discovery made possible by exploration using manned submersibles. The nodules are comparable to oceanic nodules in composition, but have some significant differences, including a more rapid rate of growth. Sedimentary-diagenetic processes are mainly responsible for their formation, but there is reason to believe hydrothermal fluids play some role.

Stable isotope data (δ¹³C) from sediment core SO201-2-101KL (58°52' N, 170°41' E) and ODP Site 1240 (00°01' N, 82°27' W), supplement to: Max, Lars; Rippert, Nadine; Lembke-Jene, Lester; Mackensen, Andreas; Nürnberg, Dirk; Tiedemann, Ralf (2016): Evidence for enhanced convection of North Pacific Intermediate Water to the low-latitude Pacific under glacial conditions. Paleoceanography, 32, 15 pp

We provide high-resolution foraminiferal stable carbon isotope (d13C) records from the subarctic Pacific and Eastern Equatorial Pacific (EEP) to investigate circulation dynamics between the extra-tropical and tropical North Pacific during the past 60 kyr. We measured the d13C composition of the epibenthic foraminiferal species Cibicides lobatulus from a shallow sediment core recovered from the western Bering Sea (SO201-2-101KL; 58°52.52' N, 170°41.45' E; 630 m water depth) to reconstruct past ventilation changes close to the source...

Influence of snow depth and surface flooding on light transmission through Antarctic pack ice, supplementary data, supplement to: Arndt, Stefanie; Meiners, Klaus M; Ricker, Robert; Krumpen, Thomas; Katlein, Christian; Nicolaus, Marcel (2017): Influence of snow depth and surface flooding on light transmission through Antarctic pack ice. Journal of Geophysical Research: Oceans, 122(3), 2108-2119

Stefanie Arndt, Klaus M Meiners, Robert Ricker, Thomas Krumpen, Christian Katlein & Marcel Nicolaus
Snow on sea ice alters the properties of the underlying ice cover as well as associated physical and biological processes at the interfaces between atmosphere, sea ice, and ocean. The Antarctic snow cover persists during most of the year and contributes significantly to the sea-ice mass due to the widespread surface flooding and related snow-ice formation. Snow also enhances the sea-ice surface reflectivity of incoming shortwave radiation and determines therefore the amount of light being...

Meteorological observations from the automatic weather stations Drescher and Filchner, 1991-2002, supplement to: Brüne, Markus (2002): Interpretation of data from the automatic weather stations Drescher and Filchner and Comparison with European Centre for Medium-Range Weather Forecasts (ECMWF) analysis model results. Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, 44 pp

Markus Brüne & Gert König-Langlo
Automatic weather stations (AWS) are due to the extreme cold conditions an attractive option to get more dens climatic data from Antarctica. These data is needed for weather forecast models or other climatic models. Data sets of the European Centre for Medium-Range Weather Forecasts (ECMWF) analysis model are used for comparison with AWS in the Weddell Sea. This region if of particular interest for the BRIOS2 (Bremerhaven Regional Ice-Ocean Simulations) model which produce results related...

Fecundity and growth of threespine sticklebacks under ocean acidification, supplement to: Schade, Franziska M; Clemmesen, Catriona; Wegner, K Mathias (2014): Within- and transgenerational effects of ocean acidification on life history of marine three-spined stickleback (Gasterosteus aculeatus). Marine Biology, 161(7), 1667-1676

Franziska M Schade, Catriona Clemmesen & K Mathias Wegner
Some studies have demonstrated that elevated CO2 concentrations in ocean waters negatively impact metabolism and development of marine fish. Particularly,early developmental stages are probably more susceptible to ocean acidification due to insufficient regulations of their acid-base balance. Transgenerational acclimation can be an important mechanism to mediate impacts of increased CO2 on marine species, yet very little is known about the potential of parental effects in teleosts. Therefore, transgenerational effects were investigated on life history in...

Seasonal variation in parasite infection patterns of marine fish species from the Northern Wadden Sea in relation to interannual temperature fluctuations, supplement to: Schade, Franziska M; Raupach, Michael R; Wegner, K Mathias (2016): Seasonal variation in parasite infection patterns of marine fish species from the Northern Wadden Sea in relation to interannual temperature fluctuations. Journal of Sea Research, 113, 73-84

Franziska M Schade, Michael R Raupach & K Mathias Wegner
Marine environmental conditions are naturally changing throughout the year, affecting life cycles of hosts aswell as parasites. In particular,water temperature is positively correlatedwith the development ofmany parasites and pathogenic bacteria, increasing the risk of infection and diseases during summer. Interannual temperature fluctuations are likely to alter host?parasite interactions, which may result in profound impacts on sensitive ecosystems.In this context we investigated the parasite and bacterial Vibrionaceae communities of four common small fish species (three-spined stickleback...

Analysis of ferromanganese deposits from Mallorca, Spain, supplement to: Prescott, D M (1988): The geochemistry and palaeoenvironmental significance of iron pisoliths and ferromanganese crusts from the Jurassic of Mallorca, Spain. Eclogae Geologicae Helvetiae, 81(2), 387-414

D M Prescott
The geochemistry of ferromanganese crusts and iron pisoliths from the Jurassic of Mallorca is investigated. The deposits are associated with Toarcian condensed sequences and hardgrounds which overlie Lower Lias platform limestones. Goethite is the principal mineral in the crusts and the pisoliths. which are both rich in iron; ramsdellite is the manganese phase in the ferromanganese crusts which contain 3-5% Mn. Inter-element relationships established by electron microprobe analysis show that P, V and perhaps Cr...

Vegetation and ecology of peat bogs from Goeldenitzer Moor and Teufelsmoor near Horst, supplement to: Precker, Axel (1993): Das Große Göldenitzer Moor und das Teufelsmoor bei Horst (Ein Beitrag zur Entstehungs- und Nutzungsgeschichte Mecklenburger Regenmoore und zu ihrer gegenwärtigen ökologischen Situation). Berichte-Reports, Geologisch-Paläontologisches Institut der Universität Kiel, 61, 127 pp

Axel Precker
Der Schutz und die Erhaltung natürlicher und/oder naturnaher Moorökosysteme sowie die Umwandlung bewirtschafteter und entwässerter - ungenutzt gebliebener - Moorstandorte oder Moorteile in Feuchtgebiete mit Moorcharakter sind in den vergangenen 20 Jahren ein wichtiges Thema für den Naturschutz geworden, was mit dem allgemeinen Rückgang wüchsiger, torfbildender Vegetation an ihren originären Standorten und deren ökologischen Besonderheiten zusammenhängt. Mit einer Ausnahme, bezeichnenderweise den Verlandungsmooren, betrifft dieser Rückgang auch alle Moortypen in Mecklenburg-Vorpommern (SUCCOW 1988), Damit ist ein...

TERENO (Terrestrial Environmental Observatories) bird monitoring in six agriculturally dominated landscapes of Saxony-Anhalt (Germany), supplement to: Frenzel, Mark; Everaars, Jeroen; Schweiger, Oliver (2016): Bird communities in agricultural landscapes: What are the current drivers of temporal trends? Ecological Indicators, 65, 113-121

Mark Frenzel & René Höhne
In 2001 we started as part of the EU FP5 project Greenveins monitoring of bird communities in the normal landscape of Saxony-Anhalt (Germany) dominated by agricultural use. We selected four landscape sites of 4x4 km (Friedeburg (FBG), Schafstaedt (SST), Greifenhagen (GFH), Wanzleben (WAN)) and recorded birds according to the point count method (see Bibby, C.J. (2000) Bird census techniques. Academic Press, London). A central core area of 3 × 3 km within each sample site...

Living and dead planktonic foraminifera faunal data from NE Atlantic multinet hauls, supplement to: Rebotim, Andreia; Voelker, Antje H L; Jonkers, Lukas; Waniek, Joanna J; Meggers, Helge; Schiebel, Ralf; Fraile, I; Schulz, Michael; Kucera, Michal (2017): Factors controlling the depth habitat of planktonic foraminifera in the subtropical eastern North Atlantic. Biogeosciences, 14(4), 827-859

Planktonic foraminifera preserved in marine sediments archive the physical and chemical conditions under which they built their shells. To interpret the paleoceanographic information contained in fossil foraminifera, the proxy signals have to be attributed to the habitat of individual species. Much of our knowledge on habitat depth is based on indirect methods, which reconstruct the depth at which the largest portion of the shell has been calcified. However, habitat depth can be best studied by...

We present results of analyses on a sediment core from Lake Karakul, located in the eastern Pamir Mountains, Tajikistan. The core spans the last ~29 cal ka. We investigated and assessed processes internal and external to the lake to infer changes in past moisture availability. Among the variables used to infer lake-external processes, high values of grain-size end-member (EM) 3 (wide grain-size distribution that reflects fluvial input) and high Sr/Rb and Zr/Rb ratios (coinciding with...

Stickleback (Gasterosteus aculeatas) egg size and offspring size in four climate scenarios, supplement to: Shama, Lisa N S (2017): The mean and variance of climate change in the oceans: hidden evolutionary potential under stochastic environmental variability in marine sticklebacks. Scientific Reports, 7(1)

Lisa N S Shama
Increasing climate variability may pose an even greater risk to species than climate warming because temperature fluctuations can amplify adverse impacts of directional warming on fitness-related traits. Here, the influence of directional warming and increasing climate variability on marine stickleback fish (Gasterosteus aculeatus) offspring size variation was investigated by simulating changes to the mean and variance of ocean temperatures predicted under climate change. Reproductive traits of mothers and offspring size reaction norms across four climate...

Analysis of Mn-deposits from the Alps, supplement to: Krainer, Karl; Mostler, Helfried; Haditsch, Johann G (1994): Jurassische Bekkenbildung in den Nördlichen Kalkalpen bei Lofer (Salzburg) unter besonderer Berücksichtigung der Manganerz-Genese = Manganese deposit genesis in the Jurrasic formations of the Northern Kalkalpen near Lofer (Salzburg). Abhandlungen der Geologischen Bundesanstalt, 50, 257-293

Karl Krainer, Helfried Mostler & Johann G Haditsch
Near Weissbach - Diessbach southeast of Lofer (Salzburg, Austria), at the western rim of the Steinernes Meer (Northern Calcareous Alps), the sedimentary sequence of a local Jurassic strike slip basin (pull apart basin) is exposed. This basin formed during the Hettangian (Lias) along E-W directed sinistral strike slip faults showing the structure of a halfgraben with a complex basin fill and asymmetric facies distribution. Along the scarp faults, some of which are still well exposed,...

Latest Cretaceous/Paleocene deep-sea ostracode fauna at IODP Site 342-U1407, supplement to: Yamaguchi, Tatsuhiko; Bornemann, André; Matsui, Hiroki; Nishi, Hiroshi (2017): Latest Cretaceous/Paleocene deep-sea ostracode fauna at IODP Site U1407 (western North Atlantic) with special reference to the Cretaceous/Paleogene boundary and the Latest Danian Event. Marine Micropaleontology, 135, 32-44

Tatsuhiko Yamaguchi, André Bornemann, Hiroki Matsui & Hiroshi Nishi
During the Paleocene, the plankton community recovered its diversity after a severe diversity loss at the Cretaceous/Paleogene (K/Pg) boundary. In general, changes in Paleocene deep-sea ostracode fauna are poorly understood. It is still unclear how deep-sea ostracode fauna changed during compelling events such as the K/Pg boundary (66.04 Ma) and the Latest Danian Event (LDE: ~62.18 Ma), a transient Paleocene warming event. In this report, we describe a study on the latest Cretaceous-late Paleocene ostracodes...

Geochemical analysis of sulfides from Lake Tanganyika, supplement to: Seiffert, Gerhard (1995): Hydrothermalismus im Ostafrikanischen Riftsystem: Mineralogische und geochemische Charakterisierung und Genese von Massivsulfiden sublakustriner Geothermalfelder im nördlichen Tanganyika-See. Berichte-Reports, Geologisch-Paläontologisches Institut der Universität Kiel, 72, 116 pp

Gerhard Seiffert
Geothermal waters with maximum temperatures of 103°C emanate from two sublacustrine hot spring areas which are located in the northem part of Lake Tanganyika (East African Riftsystem). The hydrothermalism leads to the formation of crust- and stockwork-like massive sulfide bodies on the lake bottom to a maximum water depth of 46 m. These geothermal vent areas were investigated and sampled during the German-French TANGANYDRO-campaign in 1991. The aim of this work is to characterize the...
