Description:
The study investigates salinity, depth and thickness of the isopycnals long term changes in the north northern tropical Atlantic through the density range 1026.8:1027.3 kg m-3, where oxygen minimum zone is situated. The salinity front is situated at around l8° N in the chosen density range and hydrographic property evolution is found being different to the north and south domains of the salinity front. Higher salinities during 70s than 2000-2009 period are estimated in the northern domain for all isoclines, but lower in the southern domain. Strong increase in density layer depths is observed in the southern domain intermediate water masses, i.e. Antarctic Intermediate water masses. The strongest correlation between depth and salinity anomalies is found to be -0.5 for the Antarctic Intermediate water masses, being about twice !arger than the estimates for any other water mass. In the end, the salinity front parameters such as width, gradient and variability are described over entire north tropical Atlantic.
