The Scientific staff and crew onboard CCGS Louis S. St. Laurent (LSL) returned September the 10th, 2001 from a scientific expedition to the Nares Strait, the northernmost waterway connecting the Arctic and Atlantic oceans. The data format is Society of Exploration Geophysicists SEG Y. The ice conditions in the strait required the support of Canada's largest ice breaker. The ship was a versatile platform for 34 scientists to accomplish their marine investigation. The LSL has a history of supporting international scientific expeditions including an oceanographic transect of the Arctic Ocean in 1994 and a biological study of the Canadian Arctic Islands in 1999. Germany (Bundesanstalt für Geowissenschaften und Rohstoffe, BGR) and Canada (Geological Survey of Canada) undertook a 5-week scientific cruise to study and explore the geological structure and evolution of the Nares Strait. The primary objective was the study of structural features relating to the formation of the Arctic Ocean and, in particular, the study of the Wegener Fault. This fault is a linear boundary between Greenland and Ellesmere Island which was noted by the German scientist Alfred Wegener in 1915 and later became the subject of a major scientific controversy. The co-operative cruise, which was planned over a period of 2 years, provided the basis for a wide range of scientific investigations, from marine seismic work and climate change studies through airborne magnetic investigations to geodetic survey measurements and geological sampling onshore. Systematic geophysical offshore studies in this key area had not been undertaken before. Where towing of seismic equipment was not possible because of ice coverage, magnetic maps were made using a helicopter-borne magnetic sensor system. Sediment and water samples taken during the cruise provide information on changes in climate and sea ice cover from the last ice-age to the present. An 11 m-long sediment core from outer Jones Sound is the longest core ever taken in the Canadian Arctic channels and holds clues to the detailed climate history of northern Baffin Bay.
The cruise AL278 started on May, 10th 2006 in Kiel and ended in Kiel on May, 19th 2006. The previous BGR-cruises with RV AURELIA in 2003 and 2004 were designed to collect a grid of seismic MCS-data which should enable us to get a high-resolution overview over the upper 1 s TWT of the sediments of the German North Sea sector. During October/November 2005 a subsequent cruises with RV HEINCKE and FK SENCKENBERG was designed to tackle several special aims: - The detailed mapping of glacio-tectonic features North of Heligoland. - The shallow seismic mapping of the Holocene/Pleistocene-Boundary and topography of the Pleistocene sub-glacial valley system offshore of the East Friesian Islands. - High-resolution surveying of two areas designated for offshore wind farms in the southwestern German sector. - Detailed mapping of a wide and deep sub-glacial valley. One additional aim was to acquire a dense grid of seismic line in the area North of Weisse Bank where on several from previous cruises indications for shallow gas accumulations (e.g. “bright spots”) were found. Unfortunately, due to very bad weather conditions this aim could not be reached. Therefore this short cruise with RV ALKOR was used to acquire twelve MCS lines over this area. During the cruise a total ca. 1400 km of high quality MCS lines were surveyed and simultaneously measured by a sediment echosounder system that enabled additional profiles during transits with speeds 5 kn. Together with the previously acquired data these new data should help to extend our knowledge of the Late Tertiary and Quaternary evolution of the German North Sea Sector. The BGR high-resolution multichannel seismic reflection system consisting of a GI-Gun (0.8 l) and a 300 m streamer with 24 channels and a sediment echosounder type SES 2000 standard by Innomar, Rostock. While the BGR-seismic system was used to observe the shallow subsurface down to 2 s TWT penetration depth, the sediment echosounder with a penetration depth of several meters was primarily intended to identify sampling positions for the deployment of the BGR vibration corer during the succeeding Leg 2. Additionally, the echosounder system enables the relationship to the highest-resolution multichannel seismic measurements of the group of the University of Bremen on FK SENCKENBERG. All seismic records were processed onboard for the quality control and for a first interpretation.
The PANORAMA-2 research cruise was carried out between August 15th and September 20th 2015 aboard the Italian research vessel OGS Explora, like the PANORAMA-1 cruise in 2013. The intended survey area was the European sector of the Arctic east and southeast of the Svalbard archipelago in the area of the northern Barents Sea. Main target of the PANORAMA-2 cruise was the acquisition of new geophysical data and the probing of surficial sediments in the underexplored area of the Sørkapp Basin and Olga Basin. In the course of the 20 day lasting Leg1 of the PANORAMA-2 cruise geophysical data acquisition was carried out. About 1750 km of 2D multi-channel seismic data were acquired and about 350 km of wide angle seismic data by means of sonobuoys. Sediment echosounder data, multi-beam data, gravity data and geomagnetic data were acquired during the entire cruise in a 24/7 mode within the survey area. After a 1-day stopover in Longyearbyen for a crew change of a part of the scientific crew, the research vessel OGS Explora returned to the survey area for another 11 days. During Leg-2 of the PANORAMA-2 cruise the surficial sediments were sampled by means of gravity corer, multi corer and dredge at 34 stations all together. Sediment sampling was carried out during day-light times only. Night times were used for acquisition of geomagnetic data, gravity data, sediment echosounder data and multi-beam data.
The initial study area of the cruise MSM14/2 GeoNORM (Geophysik im noerdlichen Roten Meer) was the northern Red Sea. However, because of not given research permissions from Egypt and Saudi Arabia, the study area had to be changed to the alternative study area Eratosthenes Seamount (ESM), south of Cyprus. The ESM is supposed to represent a continental fragment of the former African-Arabian Plate that is entering the subduction zone south of Cyprus i.e. the subduction turns into collision in the area of the ESM. This changed the entire tectonic setting in the Eastern Mediterranean. Therefore, the tectonic evolution of the area is rather complex with phases of extension, subduction, compression, salt tectonics and gravitational processes and not comprehensively understood. Because of the isolation of the ESM as a continental fragment this region is an ideal spot to investigate the transition from regular subduction to continental collision and its associated tectonic processes i.e. faults were activated or reactivated, transform motion has to be compensated, the overriding plate has been elevated. This impacts the ongoing geological and tectonic processes in this region but also influences the social and economic life in the Eastern Mediterranean as earthquakes and submarine landslides are possible geohazards and the entering of the ESM to the subduction trench alters the thermal history of the adjacent sedimentary basins significantly what should have an influence on the maturity processes within the source rock sediments and new faults open new migration paths for hydrocarbon fluids or gases.
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.
Reconnaissance surveys were carried out in 1974 within the framework of the BGR program "Geoscientific studies in the North Atlantic". The areas covered were the continental margin of Spitsbergen, the Barents Sea and the Norwegian continental margin. On the R/V LONGVA (10th August, 1974 - 10th September, 1974) multichannel seismic measurements were carried out on 40 lines with a total length of 8,091 km. The data format is Society of Exploration Geophysicists SEG Y.
A geophysical reconnaissance survey was carried out in the Labrador Sea and Davis Strait between July and September 1977 by BGR. The data format is Society of Exploration Geophysicists SEG Y. The survey was executed on the research vessel MS Explora. The seismic, magnetic and gravity data from 5931 line-kilometers on 21 lines were recorded on magnetic tape. A 24-fold coverage technique was used with 48 seismic channels (traces), with a 2400m streamer cable, and 23.45 l airgun array. A full integrated computerized satellite navigation system (INDAS III) served as positioning system. Based on a preliminary interpretation of the seismograms, the Labrador Sea was devided into an eastern (Greenland) and western (Canadian) area, seperated by the Mid Labrador Ridge. Within the eastern part of the Labrador Sea the Pre-Cenozoic sediments show three distinct layers, traceable over the entire Greenland area of the sea. In the Cenozoic layer olisthostromes occur. The highest apparent velocity determined from sonobuoy data was 9.26 km/sec. The calculated refractor lies at a depth of approximately 13 km. The seismic section from the sediments on the Canadian side of the Labrador Sea show a uniform series of thick sediments below the Cenozoic cover. The highly disturbed basement is often masked by the multiple reflections from the seafloor. Statements about the nature and structure of the basement can only be made after processing data.
