There is a need to automate terrain feature mapping so that to make the process more objective and less time consuming by using proper feature extraction techniques. The objective of this study was the use of object-oriented image analysis methods for the automatic extraction of physiographic regions and alluvial fan landform units. The study area was located in Nevada, USA. The data used inclu...

The common bottlenose dolphin (Tursiops truncatus) is a cosmopolitan delphinid, regularly present in the Mediterranean Sea. According to previous studies, this tends form resident geographical units scattered on continental shelf. We investigated how physiographic characteristics of area residence, with special reference size and shape shelf, affect home range group local units. analysed compar...

Incidences of non-deposition or erosion at the modern seabed and hiatuses within the pelagic caps of guyots and seamounts are evaluated along with paleo-temperature and physiographic information to speculate on the character of Late Cenozoic internal tidal
