In this paper, the physiography, geomorphological features, and sedimentary bedforms of offshore Egadi Islands (Italy) have been illustrated mapped through an integrated analysis high-resolution bathymetric, seismo-acoustic, sedimentological data. The study area is characterized by a wide, up to 25 km, continental shelf which separated NNW-trending linear incision, Marettimo Channel, along seve...

Around the North Sea, how have port cities and in hinterlands of influenced one another past? What possible links are there between population trends various urban areas time periods? Is it to identify origin urbanization patterns around Sea? To understand current era urbanization, we need analyze historical long term. By mapping figures for eight moments history combining this with data on pol...

dust storms are destructive climate phenomenon which damage farm, installations,roads,traffic and etc indemnifiable. this phenomena at dry and pertaining regions of the country as environmental perils, is effected by particular atmospheric condition.if the origin and extention of this phenomenon be recognized the damages can be decreased or counteracted.the studied about dust storm show thirtee...

Steller sea lion, Eumetipias jubatus, counts made on rookeries in the Gulf of Alaska, Aleutian Islands, and the Bering Sea from 1976 to 1991 were compared to annual estimates of walleye pollock, Theragra Chalcogramma, harvest to examine possible relationships between Steller sea lion abundance and commercial pollock fishing. Comparisons were made between Steller sea lion counts and pollock fish...

The unexpected high species richness of deep-sea sediments gives rise to the questions, which processes produce and maintain diversity in the deep sea, and at what spatial scales do these processes operate? The idea of a small-scale habitat structure at the deep-sea floor provides the background for this study. At small scales biogenic structures create a heterogeneous environment that influenc...

Abundance and distribution of fish biomass were surveyed around a Steller sea lion (Eumetopias jubatus) haulout (nonbreeding) and rookery (breeding) site in the Gulf of Alaska to test the hypothesis that seasonal occupation of either site was related to the availability of prey. The haulout and rookery are located 30 nmi (55.56 km) apart at Long Island and Marmot Island in the Central Gulf of A...

It has been known since Rhodes Fairbridge’s first attempt to establish a global pattern of Holocene sealevel change by combining evidence from Western Australia and from sites in the northern hemisphere that the details of sea-level history since the Last Glacial Maximum vary considerably across the globe. The Australian region is relatively stable tectonically and is situated in the ‘far-field...
