Can salinity-induced mortality explain larval vertical distribution with respect to a halocline? Biol.
The halocline (contour maps) obtained with the salinity data, roughly follows the isobaths, leaving most of the reefs with salinity values of ~32.
However, the salinity record stabilized at 32.50 between 10 and 30 m depth, and the halocline was located at 50 m (Fig.
It's in the deepest cenotes where the halocline effects are the most glorious.
The Black Sea water (low salinity: 18) and the Mediterranean water (high salinity: 38) do not mix with each other due to different densities of salinity, but form a salinity intermediate water (halocline) at 25 m depth of the Sea of Marmara (2).
(2008), Crassostrea virginica larvae orient toward the bottom in the absence of a halocline but tend to swim upward in the presence of a halocline.
Localised precipitation of transported metals, such as Al, can also occur during periods of stratification when high concentrations are mobilised due to pH buffering at the halocline (Pope 2006).
To maintain the halocline layer, the weakness of the turbulent mixing of the water masses is crucial (Fer, 2009).
Imagine hitting the lukewarm water-then your world suddenly blurs, and the water becomes warm enough for a hot compress as you enter a saline-dense halocline.
This equilibrium stability of offshore waters shows the thorough mixing of water and no halocline and thermocline observed in the near shore waters of Karachi [18].
Possible consequences of this relocation range from major variations in the halocline depth in the Baltic Sea (Vali et al., 2013) over jumps in the water temperature in certain characteristic layers (Mohrholz et al., 2006) and changes in the course of coastal processes (Viska and Soomere, 2012) down to subtle changes in the transition time from winter to summer circulation type (Keevallik and Soomere, 2008, 2009).
