Atmospheric and Oceanic Circulation Patterns off Northwest Africa During the Past 25 Million Years

The sediments of the eastern Atlantic contain excellent historical records of the patterns of oceanic and atmospheric circulation in the subtropics. This is particularly the case at the low relief northwest African continental margin which favors unrestrained interaction of the land- sea climatic system and which forms a schematic, vertical cross section through the ocean from the equator to Mediterranean latitudes. Our synthesis of the Neogene and Quaternary evolution of paleoenvironments along this margin tries to show that oceans and land respond in a complementary way to global climatic events and mechanisms.

Geological investigation of nearshore sand-transport—examples of methods and problems from the baltic and north seas

Abstract Many methods are available for geological investigation of sand-transport in nearshore marine waters. This paper describes morphological, petrofabric, and petrological methods (see Contents) as they are presently used in Germany. Results are given for the North and Baltic seas. Largely the report is more a description of investigations still in progress than a final and round representation of the topic, to show present trends in such studies.

Marine Geosciences: A Short, Eclectic, and Weighted Historic Account

Marine geosciences are covering all phenomena and processes related to the formations of shallow shelf seas and of the deep ocean. They draw on modern dynamics of seafloor and sediment formation, marine geophysics and tectonics, volcanology, geochemistry, microbiology, biology, and paleontology of marine organisms. They are of great economic importance because of the wealth of nonliving marine resources.
