Very little information is availabe on the temperature differences in the first several centimetres of air above the sea surface and the first few centimetres of water below the sea surface. Data of this kind are important in helping to understand heat exchange between the sea and the atmosphere. They may also be a significant factor in the phenomena of sonar surface-reverberation. A series of measurements is now underway to determine the magnitude and fluctuations of these temperature gradients during hourly, daily and seasonal intervals. These are being made in the open sea off the Ligurian Coast of Italy. The gradients are measured with respect to the actual undulating surface of the sea. The instrumentation being used is described.
