Seasonal variations of the seawater properties (e.g. temperature, salinity, density and chlorophyll-a) in western part of the southern coastal waters of the Caspian Sea near the Iranian coast were studied. A portable CTD probe was applied for profiling from sea surface to bottom at 23 stations. Maximum depth of the profiling stations was more than 470 m in the study area. Vertical structure of ...

From the early 1970's to the mid-1980's, the main thermocline of the subarctic gyre of the North Paci c Ocean shoaled with temperatures at 200-400m depth cooling by 1-4 C over the region. The gyre-scale structure of the shoaling is quasi-stationary and intensi ed in the western part of the basin north of 30N, suggesting concurrent changes in gyre-scale transport. A similar quasi-stationary cool...

A stationary SST mode is proposed to understand the physical mechanisms responsible for the phase transition of the El Niño–Southern Oscillation. This stationary SST mode differs from the original delayed oscillator mode and the slow SST mode in the sense that it considers both balanced and unbalanced thermocline depth variations and does not take into account the zonal propagation of SST. With...

A cyclonic gyre within the eastern tropical South Atlantic is resolved by an extensive oceanographic station array obtained in 1983 and 19&4. The gyre is centered near nos and SOE with a sea surface relief relative to 1500 decibars (db) of8 dyn em. The 500 db surface relative to 1500 db reveals a much diminished cyclonic circulation, shifted slightly to the south. The weak baroclinic expression...
