Abstract :
The Inverted Echo Sounder (IES) is now being widely used to study the temporal variability in large-scale features of the temperature field of the oceans. The latest generation of instruments is microprocessor controlled for functional flexibility. Optional additional measurements of bottom pressure, temperature and ambient noise are now available. The latest system incorporates new echo detection electronics and a simplified anchor release mechanism. The instruments are small, easily manageable, and may be moored in water depths up to 6700 m for 18 months.
