INSPIRE: EMODnet-DE - Offshore Geology - Pre-Quaternary (EMODnet-DE Pre-Quaternary)

Compilation of the European Pre-Quaternary marine geology (section of Germany). Project partners are the national geological services of the participating countries. The map consists of data at highest available spatial resolution, map scale („multi-resolution“-concept) and data completeness vary depending on the project partner (as of 2016 September). According to the Data Specification on Geology (D2.8.II.4_v3.0) the content of the geological map is stored in a INSPIRE-compliant GML file: EMODnet-DE_Pre-Quaternary_GeologicUnit.gml contains the geologic units. The GML files together with a Readme.txt file are provided in ZIP format (EMODnet-DE_Pre-Quaternary-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML file content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements.

INSPIRE: Marine seismic survey profiles for the German EEZ (MSSP-EEZ)

During the period from 1996 to 2007 five cruises operated by BGR acquired seismic lines from the German EEZ. The aim of these expeditions was a detailed survey of the geological structure of the seabed from the North Sea and Baltic Sea. The five GML files (for each cruise one) together with a Readme.txt file are provided in ZIP format (MSSP-EEZ-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML files content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements.

Schwerpunktprogramm (SPP) 527: Bereich Infrastruktur - Integrated Ocean Drilling Program/Ocean Drilling Program (IODP/ODP), Schwerpunktprogramm (SPP) 527: Bereich Infrastruktur - Integrated Ocean Drilling Program/Ocean Drilling Program (IODP/ODP)

Das International Ocean Discovery Program (IODP) ist ein zehnjähriges globales Vorhaben zur Erkundung der Bereiche unter den Meeresböden durch Tiefbohrungen. Es hat im Oktober 2013 begonnen und baut auf früheren wissenschaftlichen Ozean-Bohrprogrammen, namentlich dem Deep Sea Drilling Project (DSDP, 1968 - 83), dem Ocean Drilling Program (ODP, 1983 - 2003) und dem Integrated Ocean Drilling Program (IODP, 2003 - 2013), auf. Die wissenschaftlichen Ziele des neuen Bohrprogramms sind im Wissenschaftsplan 'Illuminating Earth's Past Present and Future' zusammengefasst. Darin sind vier Forschungsschwerpunkte festgelegt, die ihrerseits in insgesamt 14 verschiedene wissenschaftliche 'Herausforderungen' unterteilt sind:1) 'Climate and Ocean Change': Eine der wichtigsten wissenschaftlichen Herausforderungen ist es unser Verständnis für Änderungsraten und Ursachen globaler Klimaereignisse sowie deren Folgen zu verbessern. Die Erbohrung und Untersuchung von hochauflösenden Paläoklima-Archiven aus der Tiefsee erlauben Klimaänderungen und deren Rahmenbedingungen besser zu fassen und als Analogmodelle für den aktuellen Klimawandel sowie als Grundlage für numerische Modelle zur Vorhersage zukünftige Kimaänderungen heranzuziehen.2) 'Biosphere Frontiers': Eine weitere Herausforderung ist die Erforschung von Leben tief unterhalb des Meeresbodens, wo Mikroben isoliert von der photosynthetischen Welt an den Grenzbereichen theoretisch möglicher Lebensräume existieren. Die Erforschung dieser extremen Lebensräume erlaubt unter anderem Rückschlüsse auf die Entstehung des Lebens auf der Erde, da zu dieser Zeit ähnlich extreme Bedingungen herrschten. Eine weitere wichtige Herausforderung im Rahmen dieses Schwerpunktes ist die Beziehung zwischen Biodiversität und schnellen Umweltveränderungen. Ihre Erforschung ermöglicht Vorhersagen, wie der derzeitige Umweltwandel die marine Biodiversität und die marinen Ökosysteme beeinflussen könnte.3) 'Earth Connections': In diesem Schwerpunkt wird auf die geochemischen Austauschprozesse zwischen der festen Erde, den Ozeanen und der Atmosphäre fokussiert. Eine wichtige Herausforderung sind Bohrungen in den Erdmantel. Dieses größte geochemische Reservoir der Erde ist immer noch weitgehend unerforscht. Weitere Herausforderungen sind unter anderem ein besseres Verständnis für die Produktion ozeanischer Kruste sowie die involvierten Alterationsprozesse voran zu treiben.4) 'Earth in Motion': Dieser Schwerpunkt fokussiert auf kurzfristige geodynamische Prozesse von unmittelbarer gesellschaftlicher Relevanz. Hierunter fallen z.B. Prozesse im Zusammenhang mit Erdbeben, Erdrutschen und Tsunamis. Ebenfalls unter diesen Schwerpunkt fallen Herausforderungen wie ein Verständnis für die Bildung und Stabilität von Gashydraten und das Potential für die Sequestierung großer Mengen Kohlendioxid in Gesteinen der Tiefsee sowie die Installation von Bohrlochobservatorien.

Surveillance du site d'immersion des dechets faiblement radioactifs en Atlantique Nord-Est (FRA)

Etude des processus de remobilisation des radionuclides sur le site d'immersion de l'Atlantique Nord-Est. Ce programme comporte des campagnes oceanographiques en mer realisees en collaboration avec des instituts de recherche Allemands, Anglais et Hollandais. Sont etudies: a) Des processus de resuspension des sediments. b) La composition chimique et mineralogique de ces sediments. c) La composition chimique des particules en suspension. Ce programme s'integre au programme general de surveillance coordonne par l'Agence de l'Energie Nucleaire de l'OCDE. Trois campagnes ont ete realisees en 1982 et 1983. Les donnees obtenues sont actuellement integrees a un modele de resuspension et de circulation a petite echelle, developpe a l'Universite de Harvard. (FRA)

OBS stations of the GEOSTOR project in the German Bight and in the German Baltic Sea (WMS)

The dataset includes the locations of OBS stations (Ocean Bottom Seismometers) operated in the German Bight during cruise MSM100 with R.V. Maria S. Merian. The time interval from 13.05.2021 to 15.05.2021 has been analysed in a phase without airgun operation for passive recording with 4.5 Hz geophones. Furthermore, the dataset contains locations of 3 broadband OBS systems which were operated during an experiment at the Darss ramp in the German Baltic Sea. The records were analysed in the time interval 23.01.2018 to 01.04.2018.

Processed seismic data of Cruise MSM97 GeoHifi 2020

Regarding the use of renewable energy and the reduction of greenhouse-gas emissions, the geological storage of fluids is of particular interest. Therefore, reservoir and barrier formations in the German North Sea come into focus. Due to the widespread distribution of storage and barrier rocks at suitable depths and in combination with a relatively low tectonic overprint, the West Schleswig Block region in the German North Sea shows a high prospectivity for CO2 storage. By means of this high-resolution 2D reflection seismic survey, we want to investigate the potential impairment of geological barriers at the top of geological storage formations (i.e. claystones/mudstones and salt of the Upper Buntsandstein, mudstone dominated formations of the Lower Cretaceous and of the Tertiary). The seismic acquisition setup with a 2400 m active streamer cable with 384 channels will allow a precise image of near-surface structures, such as Quaternary channels, seismic pipe structures, chimneys, polygonal fault systems and crestal faults. In the time period between Nov. 13th and Nov. 24th we acquired 32 lines 2D seismic reflection data (about 1500 km in total) in combination with gravity data, multibeam data and sediment echosounder data. The seismic data resolve the sediments from the seafloor down to the base of the Zechstein. With the acquired data, the sediments of the Mesozoic and Cenozoic up to the seafloor (2-3 seconds of twoway-traveltime) will be imaged in high-resolution for the first time. The imaged fault systems will be investigated regarding their ability to build seal bypass systems. In addition, we acquired seismic data across the Figge Maar blowout crater and we intend to compare these data with the seismic data from the West Schleswig Block.
