SEDIMENTOLOGICAL, GEOCHEMICAL AND ISOTOPIC EVIDENCE FOR THE ESTABLISHMENT OF MODERN CIRCULATION THROUGH THE BERING STRAIT AND DEPOSITIONAL ENVIRONMENT HISTORY OF THE BERING AND CHUKCHI SEAS DURING THE LAST DEGLACIATION Sea level regression during the Last Glacial Maximum exposed the Bering Land Bridge, and cut off the connection between the North Pacific and Arctic Ocean, ending the exchange of...

The Bohai Basin was transformed to an inner shelf sea hundreds of thousands years ago. This youngest land-sea transition participated in the significant modification of the distribution of fresh water, sediment fluxes and climate in East Asia, and played an important role in the origin of the Asian marginal seas. Here we present the results of a magnetostratigraphic investigation and propose a ...

TAKEUCHI (1959) has studied on red and white muscle fibres of fresh water fish teleost (snake fish) and observed that (1) there was no difference between the membrane potential of the red muscle and that of white one (60-70mV) , (2) the red muscle did not generate the spike but did only junction potential, (3) the white muscle generated the spike but usually did not overshoot the resting potent...

Characterized as rich mineral substances, low temperature, few bacteria, and stability with numerous implementation aspects on aquaculture, food, drinking, and leisure, the deep sea water (DSW) development has become a new industry in the world. It has been report that marine algae contain various biologically active compounds. This research focued on the affections in cultivating Sagrassum cri...

MacLeod et al. (1954) noted that a number of strains of bacteria from the marine environment which can not grow on fresh water media are dependent upon Na+, K+, and Mg++, whereas several similar isolates capable of growth on fresh water media have no Na+ dependence. A subsequent investigation of the effect of these metal ions on the viability in storage and the activity of oxidative systems of ...

The present report deals with the measurement of fall-out radioactivity in Denmark in 1974. Strontium-90 was determined in samples from all over the country of precipitation, soil, ground water, sea water, grass, dried milk, fresh milk, grain, bread, potatoes, vegetables, fruit, total diet, drinking water, and human bone. Furthermore, 90Sr was determined in local samples of air, rain water, gra...

In order to evaluate the tuber fresh weight and some physiological attributes of Agria potato cultivar in response to water deficit stress and mycorrhiza inoculation, a field trial was conducted as a split plot scheme based on randomized complete block design with three replications at the research site of Islamic Azad University, Tabriz Branch in 2012. Four water levels including: irrigation a...

We examined the effects of seawater adaptation and extirpation of the Stannius corpuscles on branchial Ca(2+) flows, gill plasma membrane Ca(2+) transporters and drinking rate of European eels, Anguilla anguilla. Transepithelial Ca(2+) inflow in the gills increased 2 weeks after transfer of the eels from fresh water to sea water and after stanniectomy. Neither of these treatments changed the me...

playas are low-lands which is considered to be the locations of accumulation of superficial and ground waters fromhigher elevations and these waters have different types of salts and various salinity level. therefore, because of lack ofrainfall and fresh-water both for human and animal useage or even for plants, it is needed to apply proper methods toharvest fresh water from these saline-waters...
