temperature layer appears between 50 and 100 meters. The 

 temperatures both above and below this layer are from 1 to 

 2 degrees C. warmer than in the cold layer (referred to 

 earlier as type S-l thermal structure). At stations C-2, 

 C-3, and C-4, the warming of the upper layer is especially 

 well-marked. An explanation of the processes leading to 

 this type of temperature distribution has been discussed in 

 the section: "Thermal Structure of the Surface Layers in the 

 Antarctic Ocean."
