Editing Halocline (section)

== Global and regional halocline depths ==
[[File:Halocline cenote Chac Mool.jpg|thumb|Halocline visible at the cenote Chac Mool, [[Mexico]]. The freshwater lies above the denser saltwater. In this photo, the visible water distortion from the halocline can be seen below the diver. Note how the appearance of the safety line below the diver becomes extremely blurred by the increase in salinity|left]]
Global and regional differences in salinity, circulation, and temperature result in halocline depth variations of the different oceans. In the Arctic Ocean, the halocline is between {{cvt|50 and 250|m|ft}} deep. This can vary depending on whether the source water comes from the Atlantic or Pacific.<ref name="Vertical Stability">{{cite book |last1=Metzner |first1=E.P.|title=Determining Arctic Ocean Halocline and Cold Halostad Depths Based on Vertical Stability |date=2023 |publisher=Ocean Science |doi=10.5194/os-19-1453-2023 |page=1453-1464 |doi-access=free |url=https://os.copernicus.org/articles/19/1453/2023/}}</ref> On a global scale, haloclines are common in areas with low surface salinity, such as the tropics and subpolar regions.<ref name="Distribution">{{cite journal |last1=Ueno |first1=H.|title=Global Distribution and Interannual Variation in the Winter Halocline |date=2022 |journal=Journal of Physical Oceanography |volume=52 |issue=4 |doi=10.1175/jpo-d-21-0056.1 |page=665-680 |url=https://journals.ametsoc.org/view/journals/phoc/52/4/JPO-D-21-0056.1.xml|hdl=2115/87781 |hdl-access=free }}</ref> In shallow seas (like the Baltic) halocline depths range from {{cvt|60 to 80|m|ft}}, but they exhibit significant variability due to annul changes in wind forcing and river discharge.<ref name="Variability">{{cite journal |last1=Väli |first1=G. |title=Simulated Halocline Variability in the Baltic Sea and Its Impact on Hypoxia During 1961–2007 |journal=Journal of Geophysical Research: Oceans |date=2013 |volume=118 |issue=12 |publisher=Journal of Geophysical Research |doi=10.1002/2013JC009192|page=118 |url=https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2013JC009192}}</ref>
