Transcribed Image Text:#### Temperature vs. Depth Profile in the Ocean The figure below illustrates a temperature vs. depth profile in the ocean. The x-axis represents temperature in degrees Celsius (°C), ranging from 0°C to 24°C. The y-axis shows depth in meters (m), extending from 0 m to 4500 m. The graph includes: - A red line depicting the temperature changes with increasing ocean depth. - The temperature profile shows a rapid decrease from the surface (0 m) down to approximately 500 m, where temperatures start around 24°C and drop to about 20°C. - From 500 m to roughly 1500 m, temperature drops more steeply, from around 20°C down to about 5°C, indicating the thermocline layer. - Beyond 1500 m, the temperature remains relatively constant and low, around 4°C. **Wind-Mixed Layer:** - The wind-mixed layer, which is the surface layer of the ocean mixed by wind, extends to a depth of around 500 m in this profile. This layer is characterized by a relatively uniform temperature, which is evident from the slight temperature gradient in this region. **Key Points:** - The thermocline, a region with a steep temperature gradient, spans from approximately 500 m to 1500 m. - The deeper ocean beyond the thermocline remains at a consistently low temperature around 4°C.
