The International Geological Map of Europe and the Mediteranean Regions 1 : 1 500 000 ("Carte Géologique Internationale de l'Europe et des Régions Méditerranéennes 1 : 1 500 000") shows the geology of the European continent from the Ural mountains in the east up to Island in the west and the whole mediteranean region in the south. The geology is differenciated in stratigraphy, igneous and metamorphic rocks. In addition there are two legend sheets and a title sheet. The language of the series is French.

During the second leg of cruise BGR78 from 22th of February to 29th of March 1978 with R/V EXPLORA the following measurements have been carried out as presite- and postsite surveys of DSDP sites: (1) in the region of the eastern Walvis Ridge 4,350 km multichannel seismic reflection profiles, 4,540 km magnetic measurements, 5,000 km gravimetric measurements and sonobuoy refraction measurements on 11 stations (2) on the Guinea Plateau 740 km multichannel seismic reflection profiles in parallel with gravimetric and magnetic measurements (3) between Cape Verde islands and Mauretania 980 km multichannel seismic reflection profiles in parallel with magnetic measurements, 1,480 km gravimetric measurements and sonobuoy refraction measurements on 2 stations. The geophysical measurements show that the structure of the Walvis Ridge is determined by two main tectonic directions (WSW-ENE and SSW-NNE). Presumably the genesis of the fracture zone in the Walvis Ridge area can be traced back to the sea-floor spreading with overprinting effects due to an inhomogeneity in the mantle ("hot spot"). Both DSDP drilling projects in this part of the Walvis Ridge led to a fragmentary knowledge because site 362 got stuck at a depth of 1.100 m in the Oligocene. BGR's measurements indicate a gap of at least 1.000 m of sediments, especially from the cretaceous period, down to the (acoustic) basement. Site 363 at a submarine high has gaps in the depositional sequence and stops at a depth of 700 m shortly above the basement. So for a better understanding of the geologic development of the Walvis Ridge, further DSDP drillings with a recovery of the complete sedimentary sequence and the following basement cores are necessary. Therefore BGR's measurements of this cruise propose new DSDP sites.

With its Energy Data publication, the Federal Institute for Geosciences and Natural Resources (BGR) presents data and facts on the worldwide availability, production, import and export of energy sources. These include data on fossil and renewable energy sources. In the future, the BGR Energy Study will be published in text and table form every other year. The data tables, on the other hand, will continue to be published annually, and offered for download free of charge. The published data sets on the situation of renewable energy sources including deep geothermal energy and hydrogen, plus energy sources such as crude oil, natural gas, coal, nuclear fuels are a classified and evaluated extract of the BGR energy sources database. In addition to estimating the geological inventory of energy sources with reliable statements on reserves and resources, the energy markets are examined with regard to the global development of production, export, import and consumption. Our Energy Data are meant to advise the Federal Ministry of Economics and Climate Protection (BMWK), German industry and science, and the general public on aspects of natural resource management.
