The later SPURVS were utilized on 1-2 cruises per year by Terry Ewart and the
Applied Physics Lab's Ocean Physics Department Engineers and Research Scientists, conducting about 20 month-long cruises in total to study small scale ocean variability including internal wave and fine-structure data, point

In a few operations, two SPURVs were run at once in lock-step, 1 above the other or one beside the other at constant spacings. This was to study spatial coherences of the small scale ocean structure. Most of the SPURVs operated with a vertical rake of temperature and conductivity sensors using what

for about 4 hours. A propulsion battery consisting of 2 sets of 16 silver zinc cells connected in a parallel through diodes was the primary power source for SPURV. The battery provided a 24-volt, 200 ampere-hour supply. Secondary power came from 4 solid-state converters.

later became the
Seabird sensors. In all cases, they could be tracked from the ship—usually with the capability of using a bottom or other reference system, and pitch, roll, and heading corrections for the ship.

Acoustic signals from the accompanying research vessel guided SPURV in moving below the surface of the water. SPURV then generated models of underwater physical properties such as ocean currents and temperature.

The last operation of SPURV was in 1979 in the submarine wake study experiment. APL still has all 5 hulls, but they have not been used since then.
