2. Make detailed studies of the thermocline and its associated 

 internal waves by use of the chain. Include studies of the effects 

 on the thermocline of islands, shoals, coastal configurations, 

 tides, currents, upwelling, river runoff, water-mass boundaries, 

 storms, and seasons. Particularly, acquire more data on the di- 

 rection and speed of internal waves. 



3. Investigate the use of other sensors, in conjunction with 

 temperature on the thermistor chain, for current, sound velocity, 

 and salinity.
