Palynological analysis of eight profiles from Nepal, supplement to: Beug, Hans-Jürgen; Miehe, Georg (1999): Vegetation history and human impact in the eastern central Himalaya (Langtang and Helambu, Nepal). Dissertationes Botanicae, 318, 98 pp

Hans-Jürgen Beug & Georg Miehe
In the Eastern Central Himalaya (Langtang Valley) and its southern declivity (Helambu), palynological and phytosociological studies were carried out with the aim of reconstructing the natural vegetation pattern and elucidating the development of replacement communities between the upper cloud forest belt (2000-4000 m a.s.l.), and the alpine belt (ca. 4000-5100 m a.s.l.). According to palynological studies and historical information, the remote area under study was first influenced by man during the 15th century, presumably by...

Chemical composition of basalts from DSDP Hole 46-396B, supplement to: Böhlke, John Karl; Honnorez, Jose J; Honnorez-Guerstein, B-M (1980): Alteration of basalts from Site 396B, DSDP: Petrographic and mineralogic studies. Contributions to Mineralogy and Petrology, 73(4), 341-361

John Karl Böhlke, Jose J Honnorez & B-M Honnorez-Guerstein
Samples of crystalline basalt from Site 396 B are all more or less altered, usually in strongly zoned patterns. Evidence has been found for several related or independent alteration stages, including (1) minor localized deuteric (amphibole and mixed clay minerals in miarolitic voids); (2) minor widespread nonoxidizing (pyrite on walls of vugs and cracks); (3) localized diffusion-controlled rug filling ("glauconite" in black halos); (4) pervasive low level oxidizing (transformation of titanomagnetite to cation-deficient titanomaghemite); (5)...

Climatological observations from ship logbooks between 1750 and 1854 (release 2.1)

Philip D Jones, Dennis A Wheeler, Gunther P Können, Frits B Koek, Maria del Rosario Prieto & Ricardo García-Herrera
The Climatological Database for the World's Oceans: 1750-1854 (CLIWOC) project, which concluded in 2004, abstracted more than 280,000 daily weather observations from ships' logbooks from British, Dutch, French, and Spanish naval vessels engaged in imperial business in the eighteenth and nineteenth centuries. These data, now compiled into a database, provide valuable information for the reconstruction of oceanic wind field patterns for this key period that precedes the time in which anthropogenic influences on climate became...

The socio-economic impact of ENSO-related climate variability on rural households in Central Sulawesi, Indonesia

Alwin Keil
Data were collected in in the province of Central Sulawesi, Indonesia, in the villages of Maranata, Sidondo II, Pandere, Sintuwu, Berdikari, Nopu (Bulili), Bolapapu, and Tomado. They include information on El Nino-related drought periods experienced by 228 randomly selected farm households, and associated ex-ante mitigation and ex-post coping measures.

Recent ostracods in surface sediment samples from Admiralty Bay, King George Island, West Antarctica, supplement to: Majewski, Wojciech; Olempska, Ewa (2005): Recent ostracods from Admirality Bay, King George Island, West Antarctica. Polish Polar Research, 26(1), 13-36

Wojciech Majewski & Ewa Olempska
Ostracods from Admiralty Bay on King George Island (South Shetland Islands) represent 29 podocopid species, belonging to 19 genera, one cladocopid and six myodocopid species. They were recovered from Recent marine and/or glacio-marine sediment samples from water depths of up to 520 m. These ostracods constitute a variable assemblage, which is overall typical for the Antarctic environment. Shallow-water assemblages tend to be more variable in terms of frequencies and species richness than deep-water assemblages. The...

Composition of noble gases in sediments and metasediments, supplement to: Schwarz, Winfried H; Trieloff, Mario; Altherr, Rainer (2005): Subduction of solar-type noble gases from extraterrestrial dust: constraints from high-pressure low-temperature metamorphic deep-sea sediments. Contributions to Mineralogy and Petrology, 149, 675-684

Winfried H Schwarz, Mario Trieloff & Rainer Altherr
Solar-type helium (He) and neon (Ne) in the Earth's mantle were suggested to be the result of solarwind loaded extraterrestrial dust that accumulated in deep-sea sediments and was subducted into the Earth's mantle. To obtain additional constraints on this hypothesis, we analysed He, Ne and argon (Ar) in high pressure–low temperature metamorphic rocks representing equivalents of former pelagic clays and cherts from Andros (Cyclades, Greece) and Laytonville (California, USA). While the metasediments contain significant amounts...

Element and isotope composition of selected volcanics from the Bicol arc, Philippines, supplement to: McDermott, Frank; Delfin, Francisco G Jr; Defant, Marc J; Turner, Simon; Maury, R C (2005): The petrogenesis of volcanics from Mt. Bulusan and Mt. Mayon in the Bicol arc, the Philippines. Contributions to Mineralogy and Petrology, 150, 652-670

Frank McDermott, Francisco G Jr Delfin, Marc J Defant, Simon Turner & R C Maury
Pliocene to recent volcanic rocks from the Bulusan volcanic complex in the southern part of the Bicol arc (Philippines) exhibit a wide compositional range (medium- to high-K basaltic-andesites, andesites and a dacite/rhyolite suite), but are characterised by large ion lithophile element enrichments and HFS element depletions typical of subduction-related rocks. Field, petrographic and geochemical data indicate that the more silicic syn- and post-caldera magmas have been influenced by intracrustal processes such as magma mixing and...

Sm-Nd isotopic investigation for rocks of Prince Charles Mountains, East Antarctica, supplement to: Mikhalsky, Evgeny V; Laiba, Anatoly A; Beliatsky, Boris V (2006): Tectonic subdivision of the Prince Charles Mountains: A review of geologic and isotope data. In: Fütterer, D K, Damaske, D, Kleinschmidt, G, Miller, H & Tessensohn, F (eds.), Antarctica: contributions to global earth sciences, Springer, Berlin, Heidelberg, New York, 69-82

Evgeny V Mikhalsky, Anatoly A Laiba & Boris V Beliatsky
The Prince Charles Mountains have been subject to extensive geological and geophysical investigations by former Soviet, Russian and Australian scientists from the early 1970s. In this paper we summarise, and review available geological and isotopic data, and report results of new isotopic studies (Sm-Nd, Pb-Pb, and U-Pb SHRIMP analyses); field geological data obtained during the PCMEGA 2002/2003 are utilised. The structure of the region is described in terms of four tectonic terranes. Those include Archaean...

Data compiled within the IMPENSO project. The Impact of ENSO on Sustainable Water Management and the Decision-Making Community at a Rainforest Margin in Indonesia (IMPENSO), http://www.gwdg.de/~impenso, was a German-Indonesian research project (2003-2007) that has studied the impact of ENSO (El Nino-Southern Oscillation) on the water resources and the agricultural production in the PALU RIVER watershed in Central Sulawesi. ENSO is a climate variability that causes serious droughts in Indonesia and other countries of South-East Asia....

Daily mean surface meteorology and river discharge in Central Sulawesi for the period 2002-2005, supplement to: Leemhuis, Constanze (2006): The Impact of El Niño Southern Oscillation Events on Water Resource Availability in Central Sulawesi, Indonesia: A hydrological modelling approach. PhD Thesis, Georg-August-Universität zu Göttingen, Germany, 172 pp

Constanze Leemhuis
The El Niño/ Southern Oscillation (ENSO) phenomenon is the strongest known natural interannual climate fluctuation. The most recent two extreme ENSO events of 1982/83 and 1997/98 severley hit the socio-economy of main parts of Indonesia. As the climate variability is not homogeneous over the whole Archipelago of Indonesia, ENSO events cause negative precipitation anomalies of diverse magnitude and uration in different regions. Understanding the hydrology of humid tropical catchments is an essential prerequisite to investigate...

Palaeogeography, Palaeoclimatology, Palaeoecology, 187(3-4), 323-339

Antje Schwalb, Stephen J Burns, Gabriela Cusminsky, Kerry Kelts & Vera Markgraf
Ostracode species assemblages and stable oxygen and carbon isotope ratios of living and recent ostracodes, together with delta18O and delta13C_DIC values of host water samples, provide a first data set that characterizes a wide range of modern aquatic environments in the Laguna Cari-Laufquen (41°S, 68 - 69°W) and the Lago Cardiel area (48 - 49°S, 70 - 71°W) in Patagonia, Argentina. This data set will ultimately be used to interpret and calibrate data acquired from...

K-Ar age determination of Paleozoic rock samples from northern Victoria Land, Antarctica, supplement to: Adams, Christopher J (2006): Style of uplift of Paleozoic terranes in northern Victoria Land, Antarctica: Evidence from K-Ar age patterns. In: Fütterer, D K, Damaske, D, Kleinschmidt, G, Miller, H & Tessensohn, F (eds.), Antarctica: contributions to global earth sciences, Springer, Berlin, Heidelberg, New York, 205-214

Christopher J Adams
K-Ar ages of 82 slate and schist (white-mica-rich whole rock) samples are reported for Late Precambrian-Early Ordovician metamorphic rocks of the Wilson, Bowers and Robertson Bay terranes of northern Victoria Land. These are amalgamated in two vertical sections along composite NE-SW horizontal profiles across (1) Oates Coast in the north, and (2) Terra Nova Bay area in the south. The ages are in the range 328-517 Ma. Both profiles show some age variation with altitude,...

Palynological and stratigraphic record from Löddigsee in Mecklenburg-Vorpommern, Germany, supplement to: Jahns, Susanne (2006): Palynological investigations into the Late Pleistocene and Holocene history of vegetation and settlement at the Löddigsee, Mecklenburg, Germany. Vegetation History and Archaeobotany, 16, 157-169

Susanne Jahns
A Late Pleistocene and Holocene sediment core from the nowadays terrestrialised portion of the Löddigsee in Southern Mecklenburg, Germany was palynologically investigated. The lake is situated in the rarely investigated Young moraine area at the transition from the Weichselian to the Saalian glaciation. The high-resolution pollen diagram contributes to the establishment of the north-eastern German Late Pleistocene pollen stratigraphy. The vegetation distribution pattern after the end of the Weichselian is in good agreement with other...

European Leaf Physiognomic Approach ELPA, supplement to: Traiser, Christopher (2004): Blattphysiognomie als Indikator für Umweltparameter: Eine Analyse rezenter und fossiler Floren (Leaf physiognomy as environmental indicator : An analysis of extant and fossil floras). PhD Thesis, Geowissenschaftlichen Fakultät der Eberhard-Karls Universität Tübingen, Germany, 113 pp

Christopher Traiser & Volker Mosbrugger
Physiognomic traits of plant leaves such as size, shape or margin are decisively affected by the prevailing environmental conditions of the plant habitat. On the other hand, if a relationship between environment and leaf physiognomy can be shown to exist, vegetation represents a proxy for environmental conditions. This study investigates the relationship between physiognomic traits of leaves from European hardwood vegetation and environmental parameters in order to create a calibration dataset based on high resolution...

Rock magnetism and X-ray flourescence spectrometry analyses on sediment cores of the Lake Huguang Maar, Southeast China, supplement to: Yancheva, Gergana; Nowaczyk, Norbert R; Mingram, Jens; Dulski, Peter; Schettler, Georg; Negendank, Jörg F W; Liu, Jiaqi; Sigman, Daniel M; Peterson, Larry S; Haug, Gerald H (2007): Influence of the intertropical convergence zone on the East Asian monsoon. Nature, 445, 74-77

Gergana Yancheva, Norbert R Nowaczyk, Jens Mingram, Peter Dulski, Georg Schettler, Jörg F W Negendank, Jiaqi Liu, Daniel M Sigman, Larry S Peterson & Gerald H Haug
The Asian/Australian monsoon is an important component of the Earth's climate system that influences the societal and economic activity of roughly half the world's population. The past strength of the rain-bearing East Asian summer monsoon can be reconstructed with archives such as cave deposits, but the winter monsoon has no such signature in the hydrological cycle and has thus proved difficult to reconstruct. Here we present high-resolution records of the magnetic properties and the titanium...

Mineral analysis and geochemistry of Muehlig-Hofmannfjella granitoids, Central Drooning Maud Land, East Antarctica, supplement to: D'Souza, Mervin; Prasad, A V Keshava; Ravindra, Rasik (2006): Genesis of ferropotassic A-type granitoids of Mühlig-Hofmannfjella, Central Dronning Maud Land, East Antarctica. In: Fütterer, D K, Damaske, D, Kleinschmidt, G, Miller, H & Tessensohn, F (eds.), Antarctica: contributions to global earth sciences, Springer, Berlin, Heidelberg, New York, 45-54

Mervin D'Souza, A V Keshava Prasad & Rasik Ravindra
Ferrosilite-fayalite bearing charnockite and biotite-hornblende bearing granite are exposed in Mühling-Hofmannfjella, central Dronning Maud Land of East Antarctica. Both are interpreted as essentially parts of a single pluton in spite of their contrasting mineral assemblages. Based on petrologic and geochemical studies, it is proposed that H2O-undersaturated parent magma with igneous crustal component that fractionated under different oxygen fugacity conditions resulted in the Mühlig-Hofmannfjella granitoids.

Primary productivity and phytoplankton pigment measurements in the North Sea, supplement to: Gieskes, W W C; Kraay, Gijsbert W (1980): Primary productivity and phytoplankton pigment measurements in the northern North Sea during FLEX `76. Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe A Allgemeines, Physik und Chemie des Meeres, Gebrüder Bornträger, Berlin, Stuttgart, A22, 105-112

W W C Gieskes & Gijsbert W Kraay
During the culmination of the phytoplankton spring bloom in the Fladen Ground area in April-Mai 1976, gross primary production was between 1500 and 2000 mg particulate C m**-2 day**-1, at a crop density (mainly diatoms of the genus Chaetoceros) of about 1500-3500 mg C m**-2. Estimates of the C:chlorophyll a ratio in living cells were much lower than those reported in the literature, possibly because part of what is measured as "chlorophyll a" by the...

Observations on the propagation of internal tidal waves on the continental slope off Sierra Leone, supplement to: Fahrbach, Eberhard (1976): Einige Beobachtungen zur Erzeugung und Ausbreitung interner Gezeitenwellen am Kontinentalabhang vor Sierra Leone. Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe A Allgemeines, Physik und Chemie des Meeres, Gebrüder Bornträger, Berlin, Stuttgart, A18, 64-77

Eberhard Fahrbach
During R/V Meteor-cruise no. 30 4 moorings with 17 current meters were placed on the continental slope of Sierra Leone at depths between 81 and 1058 meters. The observation period started on March 8, 1973, 16.55 hours GMT and lasted 19 days for moorings M30_068MOOR, M30_069MOOR, M30_070MOOR on the slope and 9 days for M30_067MOOR on the shelf. One current meter recorded at location M30_067MOOR for 22 days. Hydrographic data were collected at 32 stations...

On the fine structure of oxygen distribution in surface water layers in the area between Iceland and Faroe Islands, supplement to: Grasshoff, Klaus; Johansen, J (1978): Untersuchung über die Feinstruktur der Sauerstoffverteilung in oberflächennahen Schichten im Seegebiet zwischen Island und Färöer. Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe A Allgemeines, Physik und Chemie des Meeres, Gebrüder Bornträger, Berlin, Stuttgart, A20, 109-120

Klaus Grasshoff & Jens Johannssen
During the international "Overflow-Expedition'' 1973 on R.V. "Meteor" oxygen concentrations in surface layers were measured in order to determine the oxygen gradients within the first two meters and to add some informations to the mechanisms of oxygen exchange at the air-sea interface. These investigations may be interesting also with regard to longterm- observations of the oxygen distribution in the Atlantic, especially the problem of the A.O.U. (apparent oxygen utilization) determination.To measure oxygen gradients a special...
