Starker Rückgang der Brillenpinguine

Vom 15. bis zum 18. Mai 2009 fand in Gansbaai, Westkap, Südafrika die zweite Internationale Afrikanische Pinguin Konferenz statt. Auf der Konferenz befassten sich regionale und internationale Naturschutzexperten, Wissenschaftler und Ölunfallexperten mit dem zunehmenden Rückgang des Bestands der Brillenpinguine. Laut Experten sank zwischen 1956 und 2008 die Zahl der Brutpaare von 147 000 auf 28 000 Paare am Westkap, Südafrika. Der Bestand südafrikanischer Brillenpinguine sei wegen Überfischung ihrer Nahrungsgründe und der Klimaerwärmung zurückgegangen. Weitere Faktoren könnten den Angaben zufolge Schadstoffe, Ölkatastrophen und zunehmend vorkommende Angriffe von Seehunden auf die Tiere sein.

Processed seismic data of Cruise BGR98 1998

From 24th November 1998 to 24th February 1999 BGR in cooperation with YPF (Yacimientos Petrolíferos Fiscales) and SHN (Servicio de Hidrografía Naval) conducted three seismic surveys along the passive continental margin of Argentine. The seismic vessel M/V Akademik Lazarev which is operated by SMNG (Sevmorneftegeofizika) was used for these cruises. Although the seafloor spreading history of the South Atlantic Ocean is very well defined, the development of the continental margins poses still great problems to a profound understanding. When break-up of Gondwana started in Middle Jurassic, South Africa and South America remained connected. Their break-up started in Early Cretaceous, possibly propagating from south to north. Before break-up, huge tholeiitic flood basalts were extruded near the future rift, namely the Paraná basalts in Brazil and the Etendeka basalts in Namibia. It is likely that these basalts are caused by a large mantle plume. As the flood basalts were predecessors to the break-up, often a causal relationship is assumed. The dipping reflector sequences along large parts of the continental margins of South America and South Africa are interpreted as indications of the plume influence. Investigations along many passive margins have meanwhile shown that dipping reflector sequences exist along most of them. These so-called volcanic margins are the normal ones, the non-volcanic margins are the exception. For many years, it had been assumed that the hydrocarbon potential of volcanic margins is very low. The discovery of the Kudu gas field has demonstrated that this assumption is not valid in general. This increases our interest in continuing the investigation of volcanic passive margins and the variability of their structure along strike. BGR has carried out already two marine geophysical cruises off Argentina, namely with M/V EXPLORA in 1985 and with FS SONNE in 1993. These surveys had shown locally the existence of threefold dipping reflector sequences (Hinz et al., 1999). Furthermore, it had turned out that not everywhere they are accompanied by the strong magnetic G anomaly (Rabinowitz & LaBrecque, 1979). The main objectives of the BGR98 cruise were: (1) Investigation and mapping of the zone of the seaward dipping reflectors (SDR) (reflection + refraction seismic) (2) Investigation of the sedimentary column within this zone (reflection seismic) (3) Setting up a seismostratigraphy based on the seismic records obtained during the cruise and the information from the previous cruises (BGR87, SO85) as well as on additional well information (4) Comparison of the argentine seismic data with seismic data of the conjugate volcanic margin off Namibia (BGR 87). The study area is located offshore Argentine, extending from about 37° 20' S to 45° 40' S and from about 61° 10' W to 52° 00' W. It comprises the Colorado Basin as well as the outermost shelf, slope and rise of the continental margin with water depths up to 5000 m.

Processed seismic data of Cruise BGR03 BOSA 2003

From 17th April to 6th June 2003 BGR conducted a marine geophysical cruise between 30°S and 38°S off the Atlantic coast of South Africa. The main research objective was to contribute to a better understanding of the initial breakup and the early opening of the South Atlantic. In continuation of our former work on the South Atlantic continental margins off Argentina, Brazil, Uruguay and Namibia marine geophysical research (multi-channel seismics, wide-angle refraction seismics, magnetics and gravity) was performed in cooperation with the Petroleum Agency South Africa (PASA). Multi-channel lines with a total lenght of 3,260 km, and additional 1,365km, with the other geophysical methods were acquired. Combined onshore/offshore refraction seismic work in cooperation with GeoForschungsZentrum Potsdam (Germany) and the Council for Geoscience (South Africa) was also part of the program.

Processed seismic data of Cruise BGR87

In the period from 22nd December, 1987 to 15th January, 1988 a geophysical reconnaissance survey has been carried out with S.V. EXPLORA on the Argentine Eastern continental margin. A total of 3,675 km of digital seismic reflection profiles in parallel with gravimetric and in part magnetic measurements, and 13 sonobuoy refraction profiles were recorded during this survey. The general aim of the survey was to search the Argentine eastern continental margin between 37°S and 47°S for evidence of continent-ocean boundary structures previously recognized by us off South Africa. The following preliminary results were obtained: (1) Five regional seismic markers/unconformities have been observed, named from bottom to top AR V to AR I. (2) Two units are recognizable on all reflection seismic records: A buried lower unit the top of which is marked by the distinct 'AR IV' unconformity of presumably Beriasian/Valangian age, and a tectonically undisturbed upper sedimentary unit. (3) The dominant feature of the lower unit is a 50 km to 100 km broad wedge-shaped body characterized by an internally divergent pattern of reflection horizons having seaward dip. The seismic characteristics and recent ODP drilling is consistent with the wedge being formed from extrusive basaltic rocks. (4) The more than 5000 m thick wedge is parallel with the shelf edge and can be traced continuously for 1200 km. Its landward pinchout coincides with the magnetic slope anomaly 'G'. (5) A giant contourite mound of Neogene age has been recognized in the southeastern part of the survey area. (6) Bottom simulating reflectors have been recognized. Their occurrence is associated with the contourite mound.

Okapi vom Aussterben bedroht

Die Weltnaturschutzunion (IUCN) veröffentlichte am 26. November 2013 in Gland/Schweiz eine aktualisierte Fassung der Roten Liste der bedrohten Arten. Danach sind 71.576 Tierarten gefährdet, 21.286 gelten schon jetzt als vom Aussterben bedroht. Die Bestände des Okapis (Okapia johnstoni), welches nur in den Regenwäldern der Demokratischen Republik Kongo vorkommt, sind stark eingebrochen. Es wird nun in die Kategorie "stark gefährdet" eingeordnet, welche nur eine Kategorie vor dem höchsten Aussterberisiko steht. Vor allem Lebensraumverlust und Wilderei sind für den Rückgang verantwortlich. Auch etwa 200 Vogelarten sind vom Aussterben bedroht. Dazu gehört die Spiegelralle (Sarothrura ayresi), welche in Äthiopien, Simbabwe und Südafrika vorkommt. Auch hier ist die Lebensraumzerstörung die Hauptursache für die Bedrohung.
