Atlantic continental margin Transect, Iberian Peninsula, offshore Spain
Transect across the Galicia Bank region off the Iberian Peninsula. Transect shows details of deep ocean floor (oceanic crust) structures, the ocean-continent transition zone, thinned continental crust and Iberian continental crust.

DEKORP 9 Transect, Germany
Transect crosses the Upper Rhine Graben, and obliquely intersects both the Saxothuringian and Moldanubian regions. These regions are separated by the SW-NE striking Lalaye-Lubine-Baden Baden shear zone. The Rhine Graben is a currently-active rift system.

BASIN '96 Transect, North Germany
Transect crosses the NE German Basin, a region that extends from the Palaeozoic Tornquist Suture Zone to the Harz Mountains, and from the North Sea to Poland. The basin shows a complex image reflecting different tectonic regimes and fault systems.

East European Craton – Southern margin – Stephenson
Transect across south-eastern Sarmatia, the southernmost East European Craton. The Transect crosses the Archaean-Palaeoproterozoic Ukrainian Shield, the Voronezh Massif and the intervening Late Palaeozoic Donbas Foldbelt and Dniepr-Donets Basin. Results image an inverted intracratonic rift basin and subjacent crust and upper mantle.

Etude Continentale et Océanique par Réflexion et réfraction Sismiques (ECORS) – (French language site), or
Etude Continentale et Océanique par Réflexion et réfraction Sismiques (ECORS) – (English language site)
The objective of the ECORS program is contained intirely within it's name: Continental and Oceanic study by Seismic Reflexion and Refraction (Etude Continentale et Océanique par Réflexion et réfraction Sismiques).

Centre d'Archivage et de Traitement Sismique (CATS)
The Seismic Processing and Archiving Centre is in charge of archiving and distributing ECORS and Marine Geosciences data. It also maintains for the French earth science community the tools necessary for reflection seismic processing. (French and English language site)

DEKORP(Deutsches Kontinentales Reflexionsseismisches Programm)
DEKORP (Deutsches Kontinentales Reflexionsseismisches Programm) was carried out between 1984 - 1997 as the German national reflection seismic program funded by the Federal Ministry of Education, Science and Technology (BMFT), now Federal Ministry of Education and Science (BMBF).

Pyrenees Transect, Spain
Transect that runs from the Aquitanian Basin, France, across the central Pyrenees Range to the Ebro Basin, Spain. The Pyrenees is an asymmetric double sided orogen that resulted from collision of the Iberian plate with the European continent during Alpine times.

The Causasus Transect images the geodynamics of Collision-Related Basins. The transect focuses on the Cenozoic collision-related foredeep sedimentary basins along the northern slopes of the Great Caucasus, seeking to decipher their evolution and the relationships in time and space between the basin structures and basement deformation.

The Eurobridge Transect crosses paleoproterozoic accretion of Sarmatia and Fennoscandia. The Transect is a broad transect that crosses the south-western part of the craton, extending from the Palaeoproterozoic crust of the Fennoscandian Shield to the Archaean of the Ukraine, spanning the boundary between Sarmatia and Fennoscandia.

The SW IBERIAN Transect crosses a transpressional Orogeny in the Variscides. This Variscan orogen in southwestern Iberia offers a unique opportunity to image and study a transpressional orogen and to examine the partitioning of deformation in 3-dimensional space and time.

The Geodrift Transect images geodynamics processes associated with Intracratonic Rifting within the East-European Craton. The Transect addresses the mechanisms of rifting by means of regional studies of the Late Proterozoic-Palaeozoic sedimentary basins of the EEP as well as by detailed analysis of the exceptionally well documented Pripyat-Dniepr-Donets (PDD) Basin, the largest and deepest Late Palaeozoic rift in Europe.

PANCARDI (Pannonian Basin, Carpathian arc, Dinaride ) EUOPROBE Transect
The Pancardi Transect provides information on the dynamics of ongoing Orogeny. The transect offers an outstanding opportunity to study the interaction of asthenospheric and lithospheric processes and their mutual dependencies during volcanic arc and related fore- and back-arc basin development.

Trans-European Suture Zone (TESZ) EUOPROBE Transect
The Tesz Transect provides information on phanerozoic accretion processes and the evolution of contrasting continental lithospheres. The Transect TESZ is a key enigmatic element in the evolution of the Palaeozoic orogens; together with EUROPROBE’S URALIDES project, TESZ will provide new insights into pre-Mesozoic plate tectonics and the assembly of Pangaea.

SVEKALAPKO (SVEcofennian-KArelia-LAPland-KOla) EUOPROBE Transect
The Svekalapko Transect provides information on the evolution of Palaeoproterozoic and Archaean Lithosphere beneath the Fennoscandian Shield. The transect focuses on establishing the character of the deep lithosphere (lower crust and upper mantle) and its relationship to the asthenosphere below the different parts (Lapland-Kola, Karelia and Svecofennia) of the Fennoscandian Shield.

The Timpebar Transect images basement control on Basin Evolution. The transect focuses on the evolution of Europe’s north-eastern Arctic shelf, comprising the Pechora, Eastern Barents Sea and North Kara Sea basins and their fringing terranes, which outcrop in the Timan Range (northeastern margin of the East-European Craton), Polar Urals, Novaya Zemlya, Taimyr and Severnaya Zemlya.

The Uralides Transect provides a key to understanding Collisional Orogeny. The transect across the Uralides includes a 2500-km-long suture zone that juxta-poses a collage of accreted oceanic, island arc and microcontinental terranes against a west-vergent thrust stack of foreland basin and continental margin rocks.

The Kimberlite Transect provides information on the structure and evolution of Cratonic Lithospheric Roots. The project was aimed to clarify the origin and evolution of the deep cratonic lithosphere and combine geochemical and petrological investigation of xenoliths from kimberlites and basalts with geophysical studies for definition and characterization of deep structures.
