    13/10/2018  Using the newly available 13-year Argo float data for the period 2004–2016, a three-dimensional temperature–salinity (T–S) correlation field is constructed for the global upper ocean. It is revealed that the layer-averaged correlation between T and S time series has a significant peak (~ 0.7) at a depth of approximately 300 m, suggesting that the density-compensated thermohaline ...

  • Mirror patterns of physical variables in the ocean

    Temperature and salinity are independent thermodynamic variables of seawater. However, it was determined from monthly Argo data that the correlation coefficient between layer-averaged temperature and salinity (T–S) time series peaks at a depth of approximately 300 m. Meanwhile, T–S patterns around that depth are consistent. Therefore, this layer is named “T–S mirror layer”.

  • How does the temperature of ocean water vary? :

    The temperature of ocean water also varies with depth. In the ocean, solar energy is reflected in the upper surface or rapidly absorbed with depth, meaning that the deeper into the ocean you descend, the less sunlight there is. This results in less warming of the water. Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold ...

    The physical temperature of the ocean helps regulate the amount of carbon dioxide is released or absorbed into the water. Cold water can dissolve more carbon dioxide than warm water. Temperature of ocean is also impacted the biological pump. Penetrative solar radiation warms the ocean surface causing more carbon dioxide to be released into the atmosphere. Oceanic
