Marine gravimetric and magnetic investigations within the area of the southeastern Mediterranean Sea and the northern section of Egypt
(Univ. Hamburg, 2004)The southeastern Mediterranean Sea and the northern section of Egypt constitutes one of the most complex tectonic areas in the Mediterranean. This study is an attempt to achieve a better understanding of tectonics, and ... -
Near-surface sediment structures at cold seeps and their physical control on seepage - a geophysical and geological study in the southern Gulf of Mexico and at the frontal Makran Accretionary prism, Pakistan
(Univ. Bremen, 2009)The major objective of the study is to investigate how near-surface sediment structures and other geological aspects control the nature and occurrence of cold fluid seepage. Mainly high resolution multichannel seismic data ... -
Quaternary tectonics and seismic stratigraphy of the western Black Sea shelf
(Univ. Hamburg, 2009)Interpretation of high and very high resolution reflection seismic data from the western Black Sea shelf yielded a seismic stratigraphic model of the Late Quaternary deposits on the southwestern Black Sea shelf. This model ... -
Reconstruction of oceanic currents and climate change in the Transkei Basin, South African gateway
(Univ. Bremen, 2007)Reflection seismics, sediment drifts, bottom currents. - The region south of South Africa has been a crucial gateway for large scale Thermohaline Circulations since late Eocene times. Here, three of the most important ... -
