Unlocking the Societal Potential for Change

As humanity navigates the complexities of human-environment interactions, interdisciplinary approaches that integrate psychological insights within the broader environmental discourse are essential for fostering meaningful engagement with sustainability and addressing global environmental concerns. In this publication the authors, who were participants of the “4th Summer School on Environmental Psychology” on Vilm Island in May/June 2023, explore distinct yet interconnected research topics, ranging from climate justice and emotional responses to sustainability strategies, incentives for pro-environmental behavior and the social implications of emerging technologies. In conclusion, these papers show how environmental psychology offers a multifaceted lens through which to examine and address pressing environmental challenges. These insights therefore offer valuable tools on how to further proceed on the United Nations Goal of living in harmony with nature on the global and local level.

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.

Internationale Geologische Karte von Europa und den Mittelmeerregionen 1:1.500.000 (WMS)

"Carte Géologique Internationale de l'Europe et des Régions Méditerranéennes 1 : 1 500 000" - Anlässlich des 2. Internationalen Geologen-Kongresses in Bologna 1881 wurde von der neu gegründeten "Kommission für die geologische Karte von Europa" der Beschluss zur Herausgabe einer Internationalen Geologischen Karte von Europa im Maßstab 1 : 1 500 000 (IGK 1500) gefasst. In den Händen der Kommission lag die Kompilierung und Herausgabe des Kartenwerkes; Redaktion und Druck oblag der Preußischen Geologischen Landesanstalt und ihrer Nachfolger, sprich dem Reichsamt für Bodenforschung und der Bundesanstalt für Geowissenschaften und Rohstoffe. 1913 - 32 Jahre nach dem Beschluss zur Erstellung des Kartenwerks - wurde die 1. Auflage mit 49 Blättern fertig gestellt. Für eine 2. Auflage entschied man sich bereits 1910. Doch bedingt durch die beiden Weltkriege wurden zwischen 1933 und 1959 nur 12 Blätter gedruckt. 1960 fiel der Vorschlag für eine kombinierte 2. und 3. Auflage der Karte. Im Zuge dieser Neukonzeption erschien 1962 eine neue Legende, 1970 deren Erweiterung. 1964 wurden die ersten Blätter der Neuauflage gedruckt. Ende 1999 lagen alle 45 Kartenblätter der Neuauflage vor, wobei das letzte Blatt "AMMAN" bereits digital mit Freehand 8 erstellt ist. Titelblatt und Generallegende, die auf zwei Blättern des Kartenwerks platziert sind, wurden im Frühjahr 2000 - 87 Jahre nach Abschluss der 1. Auflage - gedruckt. Das vollständige Gesamtwerk der Internationalen Geologischen Karte von Europa im Maßstab 1 : 1 500 000 (IGK 1500) wurde auf dem Internationalen Geologen-Kongress in Rio de Janeiro im August 2000 vorgestellt. Die IGK 1500 zeigt auf 55 Blättern die Geologie des europäischen Kontinents vom Osten des Uralgebirges bis Island sowie der gesamten Mittelmeerregion. Die Geologie wird unterschieden nach Stratigraphie, magmatischen und metamorphen Gesteinen. Zusätzlich gibt es zwei Legendenblätter und ein Titelblatt. Die Sprache des Kartenwerks ist Französisch.

Processed seismic data of Cruise SO186 SeaCause II 2006

SeaCause cruise SO186-2, aboard the RV Sonne, was carried out off northern Sumatra between 21st January and 24th February 2006, with mobilisation and demobilisation in Singapore and Penang, Malaysia, respectively. The geophysical survey acquired multichannel seismic data (MCS) using a 240 channel, 3 km Sercel streamer, and a tuned airgun array comprising 16 airguns with a total capacity of 50.8 litres. Bathymetry data, using the 12 kHz Simrad swath system, subseabed data using the hull mounted high resolution Parasound profiler together with gravity and magnetic data were also acquired. The main scientific objective of the survey was to investigate the southern part of the rupture zone of the 26th December 2004 9.3 magnitude earthquake, that caused the catastrophic tsunami of that date, and the rupture zone of the 8.7 magnitude earthquake of March 28th 2005. Specifically, to identify the segment boundary between the two earthquakes, as recognised by the distribution of their aftershocks. This was to be achieved by mapping the structure of the subduction zone including the dip angle of the subducted plate, the architecture of the accretionary prism and the structure of the forearc basins, particularly their strike-slip fault systems. Also to be investigated was whether there was a contribution to the 2004 tsunami from major submarine failures. During the survey a total of 5358 line kilometres of MCS data were acquired, mainly on lines oriented orthogonal to the subduction zone and extending from the ocean basin across the trench and accretionary prism to the forearc basins offshore Sumatra. The orthogonal survey lines were located on average approximately 40 km apart. The survey was planned using the bathymetry from the HMS Scott, RV Natsushima and RV Sonne cruises carried out in 2004. The morphology of the trench and sediment thickness varies from north to south. In the north the trench is poorly defined with shallow seabed dip but with sediment thickness of ~3.5 secs (TWT). The seafloor dips increase southwards, but sediment thickness decreases to ~2.5 secs (TWT) off Nias. Both the ocean basin and trench sediments are dissected by numerous normal faults, oriented subparallel to the plate boundary, with many that penetrate the oceanic crust. In the south Fracture Zones were identified. The structure of the deformation front on the seaward margin of the accretionary prism is highly variable. While the younges main thrust are predominantly landward vergent there are examples for seaward verging thrusts. The frontal fold develops in some cases already in the french while in most cases the frontal fold is at the beginning of the accretionary wedge. At some locations there are large sediment slumps on the frontal thrusts, the slope angle of the prism varies between 6 to 15 degrees, an angle that explains the large scale slumping. The width of the accretionary prism is widest in the north of the area at 140 km and narrows southwards until in the vicinity of the islands it is 40 km. In the north and central parts of the survey area the passage from the deformation front landwards into the older prism is rapid and the seabed gradients steep. The dip of the oceanic crust remains low and there is an obvious twofold increase (6-7 seconds TWT) in the sediment thickness. The basal decollement of the thrusts at the deformation front is in the lower sediment layer overlying oceanic basement. This is traced northeastward. A possible explanation for the increase in thickness of the prism is therefore considered to be the formation of a thrust duplex. Perhaps this is due to the subducted sediment thickness. In this region the prism forms a plateau and the internal pattern of the uppermost sediments shows striking similarities to the trench fill. Offshore of Simeulue Island the prism structure changes and it forms the more usually seen taper. The offscraped sediment forms a thinner section, the thrusts are more steeply dipping. The dip of the subducted plate here is greater than in the north. Three forearc basins were surveyed. In the north the western margin of the Aceh Basin lies along the West Andaman Fault. Within the main basin the sediments are internally undeformed. Farther south in the Simeulue Basin the northern and central parts there are numerous, active steeply dipping faults. In southern part of the basin there is a transpressional fault similarly to the Mentawi Fault off southern Sumatra. There are notable ‘bright spots’ in the upper section that may indicate the presence of hydrocarbon gas. There are also widespread Bottom Simulating Reflectors indication the presence of gashydrates and there may be also one double BSR. At the southern end of the surveyed area the Nias Basin may be subdivided along its length into two parts by a northnorthwest to southsoutheast trending carbonate platform development. The basin has had a varying subsidence history, in the south the subsidence was completed before the northern part started.

Processed seismic data of Cruise AL278 2006

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.

Processed seismic data of Cruise SO161 SPOC 2001

Within the frame of the comprehensive SPOC project (Subduction Processes off Chile) the SONNE cruises SO161 Leg 2 and 3 have been conducted between October 16th and November 29th, 2001, off central Chile between 28° and 44° S. In that period some 5,300 km were surveyed with multichannel seismic (MCS) reflection, magnetic, gravity, high-resolution bathymetric and echographic methods. In addition, approximately 3,900 km were surveyed with the same spectrum of methods but without MCS. The total number of 2D profiles was 48. Target was the variation of the subduction properties between the convergent oceanic Nazca and continental Southamerica plates and the different conditions that might influence the subduction process as there are: (1) age of the oceanic crust, (2) its structure and composition, (3) its sedimentary cover, (4) its thermal state, (5) the subduction angle and obliquity, and (6) the terrigenous sediment afflux from the continent. Furthermore, special focus was given to the subduction front, the subduction interface, the structure of the slope as well as to the forearc basin structure and history, and the general distribution of gas hydrate indicating bottom simulating reflectors (BSR's). The results are to be compared with previous studies of the Chilean active margin, e.g. CONDOR (SO 101 and 103) and CINCA (SO 104). The SPOC target area was subdivided into three sub-areas A,B and C. One area was chosen for a detailed survey by aid of a narrowly spaced grid and for a close link with a lot of partners. This area is characterized by a distinctly different margin type south of it is assumed. Moreover, the subducting portion of the aseismic Juan Fernandez Ridge is located in that area representing another important target of the survey. Advantageous conditions enabled the survey of an east-west profile south of Chiloé Island, providing a section through the submerged coastal Cordillera into the flooded longitudinal valley. Some results of Leg 2 and 3 are: In all areas A, B and C no subduction bulge (outer high) in the oceanic crust was visible perhaps due to the shortness of the profiles. The sedimentary cover of the oceanic crust is exceptionally thin, and the crustal thickness is generally quite "normal" with around 7 km derived from relatively weak Moho reflections. In area B a so far magnetically unmapped region was filled providing reliable ages of the oceanic crust, and suggesting that the Challenger Fracture Zone abruptly terminates west of the area of investigation. The survey in area C yielded valuable information on the trench morphology. The so far unique MCS profile south of Chiloé island shows a very wide trench and allows to extrapolate the general conditions encountered an area A southward to approximately 44° S. It can be stated that the situation is in sharp contrast to the basin structures detected by industry profiles further north in the Golfo de Corcovado.

Processed seismic data of Cruise SO189 SUMATRA 2006

The SUMATRA cruise SO189 Leg 1, aboard the RV SONNE, was carried out off Sumatra between 3rd August and 3rd September 2006, with mobilisation in Penang, Malaysia and demobilisation in Jakarta, Indonesia, respectively. The survey was dedicated to marine geophysical measurements and acquired multichannel seismic data (MCS) using a 240 channel streamer, and a tuned airgun array comprising 16 airguns with a total capacity of 50.8 litres. Bathymetry data, using the 12 kHz Simrad swath system, sub-seabed data using the hull mounted high resolution PARASOUND profiler together with gravity (G) and magnetic (M) data were also acquired. Along two lines with a total length of ~ 390 km refraction/wide-angle seismic experiments were carried out. During the survey a total of 4,375 line kilometres of MCS, M and G data were acquired and an additional 990 km with M and G alone. The 41 MCS lines cover as close grid three fore-arc basins. Five lines extend nearly orthogonal to the subduction front and, thus, cover the whole subduction system from the adjacent oceanic plate, the trench and accretionary prism over the Outer Arc High to the forearm basins offshore Sumatra. The survey was planned using the bathymetry from the HMS SCOTT, RV NATSUSHIMA, RV MARION DUFRESNE and RV SONNE cruises carried out in 2004, 2005 and 2006. The main scientific objective of the project SUMATRA is to determine or estimate the hydrocarbon (HC) system (source rocks, HC generation, HC migration and reservoir rocks) of the Sumatra fore-arc region (mainly the fore-arc basins). Cruise SO189 Leg 1 was designed to investigate the architecture, sedimentary thickness, sedimentary evolution and subsidence history of the fore-arc basins Siberut, Nias and Simeulue off Sumatra. In the Simeulue Basin it was possible to connect the seismic lines to three industry wells and to correlate the seismic horizons to the results from the wells. The Simeulue Basin is divided into a northern and southern sub-basin. Carbonate build-ups were found in the northern sub-basin only on the very shallow shelf in the north-east. The maximum thickness was determined to be ~ 3 s TWT. In the southern sub-basin carbonate build-ups (which were already identified on some lines of the SEACAUSE project), bright spots and Bottom Simulating Reflectors (BSRs) are wide spread. The narrowest basin surveyed was the Nias Basin. As the Simeulue Basin the Nias Basin is divided into two sub-basins which are separated by a structural high. Although the basin has a maximum width of only 55 km the maximum sediment thickness exceeds 5 s TWT. The largest fore-arc basin is the Siberut Basin. It extends from the equator to ~ 5°S over 550 km and has a maximum width of 140 km between the island of Siberut and Sumatra. The maximum sediment thickness in this basin is 4.8 s TWT. The basin geometry is uniform along its axis. At the basins termination on the western side to the Outer Arc High the Mentawai Fault Zone could be traced. The geometry of this major fault changes significantly along strike. In some areas it is traceable as one single fold whereas in other areas it spreads in up to three different branches indicating splay faults originating from a main fault. In the Siberut Basin BSRs are very wide spread and very good recognizable over the Mentawai Fault Zone. Along the Mentawai Fault and along the eastern rim of the basin the seismic data show strong indications for active venting. The morphology of the Sunda Trench and its sedimentary cover varies from north to south. In the north the trench is poorly defined with shallow seabed dip but with sediment thickness of ~ 3.5 s TWT. The seafloor dips increase southwards, but sediment thickness decreases to ~ 2.5 s TWT off Nias. Both the ocean basin and trench sediments are dissected by numerous normal faults with a maximum displacement of 0.6 s TWT. Along strike the deformation front between Nias and Siberut displays several incipient folds. As offshore northern Sumatra, both landward (BGR06-228) and seaward verging folds (BGR06-227) are developed at the deformation front. For the first time landward verging folds have now been imaged in this domain of the Sunda subduction zone. In contrary to first thoughts during the expedition SO186-2 SEACAUSE, landward verging folds are not limited to the area off Aceh. Two refraction lines were acquired parallel to the subduction front at 2°30'N and 1°30'S approximately 40 - 50 km seaward of Simeulue and Siberut Island, respectively. The lines were designed to identify the segment boundaries in the subduction system as well as to detect and decipher the subducted aseismic Investigator Ridge. The gravity data set consists now of over 38,000 line km (combining the GINCO, SEACAUSE I and II and the SUMATRA data). With this it was possible to compile a map of the free-air gravity from the northern tip of Sumatra (~ 6°30'N/95°E) to Mid Java( ~8°30'S/110°E). Gravity modelling in parallel with refraction seismic data interpretation was carried along two lines during the cruise. The preliminary results show that the incoming oceanic plate is unusual thin both in the north off Simeulue (6 km) and in the south off Nias (5 km).
