Processed seismic data of Cruise VA16 1977

The northwestern Australian continental margin can be considered as a passive continental margin of the rifted atlantic type (Whitworth 1969; Powell 1973, 1976; Falvey 1974; Veevers 1974; Willcox 1974, 1976; Exon et al. 1975) which are usually associated with heavy accumulation of sediments (Beck et al. 1974) and are therefore of interest for hydrocarbon exploration in the longer term. The Federal Institute for Geosciences and Natural Resources (BGR, Hannover, Germany) has conducted geoscientific surveys at various continental margins of the Atlantic Ocean in the past years (Seibold 1972; Hinz et al. 1973; Seibold, Hinz 1974/1976; Seibold et al. 1975; Roeser et al. 1971) and the marine research programme of the Bureau of Mineral Resources, Geology & Geophysics (BMR, Canberra, Australia) is putting the focal point as well on the survey of the continental margins. Hence in the frame of the Australian-German contract of scientific and technical cooperation, BGR has proposed joint geoscientific surveys of the continental margins with the German research vessel VALDIVIA. The Scott-Plateau (NW-Australia) has been chosen as investigation area because BMR has carried out geophysical overview measurements previously in that region. The survey has been planned with the main focus on the geological processes at the early rift stadium and the set of problems about the "transition of oceanic to continental crust". The following regional geological units are known: the archaic-proterozoic Kimberley shield is followed by the Browse Basin - a NE striking epicontinental basin filled with mesozoic and tertiary sediments showing a thickness of up to 10 km (Powell 1976). It is presumed that the Browse Basin is delimitated by the Scott Plateau. Presumably, the Scott Plateau consists of continental crust which thins out to the north in direction to the Argo Abyssal Plain. The development of the Browse Basin is ascribed to a series of rift processes in the late paleozoic and triassic age where gas condensates have been detected at the drill hole Scott Reef 1. The contemporary configuration of the NW-Australian basins and the NW-Australian continental margin has been formed by an important middle jurassic rift phase and a subsequent drift phase. The cruises VA16-2A from 6th to the 25th of February 1977 with geophysical measurements and VA16-2B from 25th of February to 9th of March 1977 with geological sample recovery should clarify these processes. The working area of cruise VA16-2C from 11th to 23rd of March 1977 has been the Timor Trough and the Savu Sea which separate the islands Timor, Roti, Savu and Sumba from the volcanic islands of the inner Banda island arc. The crustal structure of Sumba, of the Savu Sea and of the inner Banda island arc near Flores should be investigated with seismic methods (small explosive charges fired from the research vessel VALDIVIA in the Savu Sea and intended recording units of the Flinders University on the islands Savu, Sumba and Flores) as well as with sonobuoy stations of BGR. Newer investigations (Audley Charles 1975, Chamalaun 1974) suggest that the islands of the Banda island arc (Sumba, Savu, Roti, Timor etc.) represent the northern border of the Australian continent being underlain by the crust of the Australian continent as opposed to the assumption of other investigators (e.g. Beck and Lehner 1974) who presume the northern border of the Australian continent at the Timor Trough south of the Timor island and postulate a subduction zone between the outer Banda island arc and Australia. BMR has provided 9 tons of explosives (Nitramon) with accessories for refraction seismics. The Flinders University has prepared 7 on-shore recording units and sent to Indonesia together with operating staff. BGR conducted the marine seismic work with explosive charges and off-shore recordings with sonobuoys for refraction seismic as well as reflection seismic, gravimetric and magnetic measurements.

CASE Outcrop Data (WMS)

The web service of the dataset comprises the locations of outcrops with respective information on the lithology, stratigraphy, rock age and tectonic data collected during the CASE expeditions. The data attributes include stereographic projections and sketches of tectonic structures derived from the outcrop data. At the end of the 1980s, BGR initiated the research program Circum-Arctic Structural Events (CASE) to reconstruct the plate tectonic processes during the evolution of the Arctic Ocean using terrestrial data from the surrounding continental margins. One of the scientific questions of the CASE programme is as simple as it is complex: How did the Arctic Ocean, this large basin between the Eurasian and North American continental plates, develop? There are still no conclusive answers to this question in terms of plate tectonics. In contrast to the marine expeditions of geophysicists in the Arctic Ocean, geologists on land along the various coastal areas of the Arctic Ocean can directly touch, examine and map rocks, structures, folds and fault zones and determine the respective ages of the movements. This makes it possible to directly compare rock units and deformation zones on different continental plates and thus also to reconstruct when these plates collided, how long they remained next to each other and when and how they separated again. Since the inception of BGR’s Arctic research, the primary focus and research areas have been along the continental margins between Spitsbergen and the Canadian Arctic Archipelago via Greenland, to the Yukon North Slope on the border with Alaska. On the opposite side of the Arctic Ocean, there have been expeditions to Yakutia, the mainland areas near the Laptev Sea, the New Siberian Islands and to the Polar Ural with Russian partners. An important method for the interpretation of the geological evolution of the Arctic is the examination of tectonic structures (faults, folds, cleavage etc.), the determination of the kinematics and the age of the tectonic movements.

Total biomass

These data sets are based on approx. 1400 stations sampled in the German Baltic Sea by the Leibniz Institute for Baltic Sea Research (IOW) during the past 15 years (as part of the regular monitoring or within different research programmes). Benthic samples were taken with a 0.1 m² van Veen grab. Depending on sediment composition, grabs of different weights were used. As a standard three replicates of grab samples were taken at each station. Additionally a dredge haul (net mesh size 5 mm) was taken in order to obtain mobile or rare species. All samples were sieved through a 1 mm screen and animals were preserved in the field with 4% formaldehyde. For sorting in the laboratory, a stereomicroscope with 10–40 magnification was used, species were counted and weighted. Total ash free dry weight biomass was derived using random forests statistical analysis (Breiman, 2001) in R environment (Version 3.0.2, The R Foundation for Statistical Computing, 2013) and the package ‘random Forest’ (RF, Version 4.6–7, Liaw and Wiener, 2002). Total biomass shows AFDW biomass g per m².Environmental data used as predictors: Substrate (Tauber 2012), Depth (FEMA project), Salinity mean, temperature mean JJA, bottom velocity max (GETM, Klingbeil et al. 2013) Light penetration depth (mean over growth period), oxygen deficit zones (number of days / year smaller 2 ml / l) and detritus rate (mm / year) (ERGOM, Friedland et al. 2012).

For sorting in the laboratory, a stereomicroscope with 10–40 magnification was used, species were counted and weighted. Macrobenthic species richness was derived from stations based data by ordinary kriging of centered-point-data acquired via fishnet of 5 km x 5 km cell size. Macrobenthic species richness shows the number of species for 1 km grid.Environmental data used as predictors: Substrate (Tauber 2012), Depth (FEMA project), Salinity mean, temperature mean JJA, bottom velocity max (GETM, Klingbeil et al. 2013) Light penetration depth (mean over growth period), oxygen deficit zones (number of days / year smaller 2 ml / l) and detritus rate (mm / year) (ERGOM, Friedland et al. 2012).

Studie warnt vor den möglichen Einfluß steigender Temperaturen auf den Anbau von Arabica-Kaffee

Zunehmende Wärme und Trockenheit können den wild wachsenden Arabica-Kaffee gefährden. Zu diesem Schluss kommt eine Studie des internationalen Forschungsprogramms zu Klimawandel, Landwirtschaft und Nahrungsmittelsicherheit CCAFS, die am 14. April 2015 in der PLOS veröffentlicht wurde. Arabica-Kaffee reagiere sehr empfindlich auf Umweltfaktoren und gedeihe nur bei bestimmten Temperaturen und Niederschlagsmengen. Eine Temperaturerhöhung ab zwei Grad Celsius und Änderungen der Regenhäufigkeit und -menge könnten deshalb in den wichtigsten Erzeugerländern wie Brasilien, Vietnam, Indonesien und Kolumbien zu schweren Verlusten führen. Weil kommerzielle Kaffeesorten genetisch stark verarmt sind, benötigt man ständig Wildstämme als genetisches Reservoir, um den Kaffee vor neuen Schädlingen, Krankheiten oder auch Umweltveränderungen schützen zu können.

BMBF startet mit zehn EU-Staaten Forschungsprogramm zu Mikroplastik in marinen Systemen

Das Bundesministerium für Bildung und Forschung hat ein europaweites Forschungsprogramm zum Thema Mikroplastik initiiert. In Zusammenarbeit mit neun weiteren Mitgliedsstaaten (Belgien, Frankreich, Irland, Italien, Niederlande, Norwegen, Portugal, Schweden, Spanien), startete im Februar 2015 erstmalig eine gemeinsame Förderbekanntmachung über alle zehn Länder hinweg zu "Mikroplastik in marinen Systemen", mit einer Gesamtfördersumme von bis 7,5 Millionen Euro. ("Ecological aspects of marine microplastics" der Joint Programming Initiative on Healthy and Productive Seas and Oceans). Das BMBF unterstützt damit deutsche Forschungsorganisationen, sich an der Erforschung offener Fragen zum Thema Mikroplastik zu beteiligen. Mit der Pilotmaßnahme soll eine einheitliche Messmethodik entwickelt werden, um wissenschaftliche Untersuchungen besser vergleichen zu können. In einer globalen Studie wird dargestellt werden, auf welchem Wege das Plastik in die Meere gelangt, wie sich die Partikel in der marinen Umwelt verbreiten und welche toxikologischen Effekte sie auf marine Organismen haben und damit auf den Menschen am Ende der Nahrungskette. Geplant ist, dass die Ergebnisse aus den geförderten Projekten in einen gemeinsam formulierten Aktionsplan der G7-Wissenschaftsministerkonferenz zu Forschung und Innovation gegen Meeresvermüllung münden. Durch die Joint Programming Initiative "Productive and Healthy Seas and Oceans (JPI OCEANS)" werden zwischenstaatliche europäische Aktivitäten zum Thema Meere und Ozeane gebündelt, koordiniert und entwickelt.
