Caspian Sea with an average depth of 27m is the largest enclosed water body in the world. Despite its enormity and valuable biotic and economic resources, investigations on the biota and seawater properties are mosaic at best. In previous studies, the monitoring of the chlorophyll-a concentrations in the Southern Caspian Sea was organized based on satellite data sets however, vertical dis...

It has become increasingly clear that air-sea coupling is important to the earth's weather and climate [e.g., Grotzner et al. 1998, Xu et al. 1998]. The oceanic surface mixed layer is the link by which the air and sea are coupled. Further, the form and strength of the mixing motion are important to important concerns such as the fluxes of gases and nutrients and the growth and health of marine ...

Nutrient cycling in Lake Tanganyika is influenced by the tilting of the thermocline (Coulter 1991). Prevailing southeast winds during the four month dry season (May through September) cause the thermocline to rise in the south bringing nutrient rich waters from depth to the surface at the southern end of the lake (Coulter 1991). However, related upwelling events also occur in the north, bringin...

Temperature is often an important variable influencing the vertical position of fish larvae in water column. The same species may show different distributions areas with a strong near-surface seasonal thermocline compared to isothermal regions. In surface thermocline, tuna significant preference for warmer layers. Little known regarding larval distribution waters and on associated assemblages. ...

The study addresses the distribution and diversity of mesozooplankton near the active volcano-Barren Island (Andaman Sea) in the context of persistent volcanic signature and warm air pool existing for the last few months. Sampling was done from the stations along the west and east side of the volcano up to a depth of 1,000 m during the inter monsoon (April) of 2006. Existence of feeble warm air...

Cold nutrient-rich water from below the shallow seasonal thermocline is sometimes injected into the surface layer when a storm passes in a warm season. Decrease in sea surface temperature (SST) and increase in chlorophyll-a concentration (Chl-a) in a short period due to storm passages have been clearly captured by satellite observations [1]. Understanding the short-term Chl-a increase phenomena...
