In order to make any sea level dive table usable during high altitude diving, a new conversion factor is created. We introduce the standardized equivalent sea depth (SESD), which allows conversion of the actual lake diving depth (ALDD) to an equivalent sea dive depth. SESD is defined as the sea depth in meters or feet for a standardized sea dive, equivalent to a mountain lake dive at any altitu...

The ocean algorithm is based on the physical Radiative Transfer Model (RTM) described in Wentz and Meissner [2000]. The RTM consists of an atmospheric absorption model for water vapor, oxygen and liquid cloud water and a sea surface emissivity model that parameterizes the emissivity as function of sea surface temperature, sea surface salinity, sea surface wind speed and direction. The details o...

The Solomon Sea is a key region of the southwest Pacific Ocean, connecting the thermocline subtropics to the equator via western boundary currents (WBCs).Modifications to watermasses are thought to occur in this region because of the significant mixing induced by internal tides, eddies, and the WBCs. Despite their potential influence on the equatorial Pacific thermocline temperature and salinit...

abstract   background : natural uranium exists in earth crust and seawater. the concentration of uranium might increase by human manipulation or geological changes. the aim of this study was to verify susceptibility of laser flourimetry method to determine the uranium concentration in caspian sea and persian gulf water.   materials and methods : laser flourimetric method was used to determine t...

The present paper explores the result of hygrothermic aging of polymethacrylimide (PMI) foam core sandwich composites immersed in different temperature deionized (DI) and sea waters. The prepared specimens were tested for moisture up-take behavior and the resulting property degradation in terms of flexural and flat wise compressive strength. The results indicate that the saturated hygroscopic t...

Micropuncture techniques have been used to investigate kidney function in lampreys adapted to hyperosmotic media. Plasma electrolyte concentrations were maintained well below corresponding concentrations in the external environment. Urine composition was variable, but generally showed high concentrations of magnesium, sulphate and chloride ions. Lampreys in 50% sea water produced urine which wa...

Salinity tolerance to Thai silver barb, Barbodes gonionotus was investigated under laboratory conditions using common salt (NaCl) and sea water. With a view to determine the median lethal concentrations (LC50 values), the fish were exposed to various concentrations of the salt and sea water for a period of 96. Common salt up to a concentration of 12 ppt and sea water up to a concentration of 10...

The functional gene amoA was used to compare the diversity of ammonia-oxidizing bacteria (AOB) in the water column and sediment-water interface of the two freshwater lakes Plusssee and Schöhsee and the Baltic Sea. Nested amplifications were used to increase the sensitivity of amoA detection, and to amplify a 789-bp fragment from which clone libraries were prepared. The larger part of the sequen...
