These will operate at approx. 1200 m depth. Thus they can be built of 6061 alloy which is cheaper than the 7075 alloy of the abyssal Shearmeters.

They will be acoustically tracked, as before. They will have several new features: active buoyancy control so they can remain at the density of an injected chemical tracer; a precision CTD at one end; a precision thermometer at the other end to provide data to be used for computing gradient Richardson number (Ri) (with the aid of TS relation obtained because water will heave past the float); rapid sampling to resolve internal wave strain and Ri and Iridium capability to upload the large data set.

Mechanical float systems are being built bu Webb Research Corp. The electronics systems are being built by the WHOI AOPE Department.
