✦ Synopsis

Multifractal characteristics of the upper layer thermal structure in the southwestern Greenland Sea, Iceland Sea, and Norwegian Sea (GIN Sea) are analyzed using high-resolution, digital thermistor chain data. The energy spectrum at 20 m depth (cold sublayer) shows the existence of a spike at the scale of approximate 3 km representing the chimney scale. The graph dimension varies from higher values such as 1.89 at the surface to 1.44-1.50 in the warm intermediate layer.

The stationarity decreases from the ocean surface to the warm intermediate layer. However, the information dimension varies slightly (0.92 to 0.90) that indicates low singularity.
