An expendable oceanographic probe includes a body having a weighted nose section and an after body having a tail for stabilization. A spool of wire is paid out through the tail of the after body for coupling to a data acquisition system. The expendable oceanographic probe also includes a sensor exposed to the seawater for measuring a seawater property and for providing a signal representing the measured property to the data acquisition system over the wire. A pressure sensor of the probe is exposed to the seawater for determining the depth of the probe as the probe descends into the seawater with respect to the measured seawater property by perturbing the measured parameter signal at a predetermined pressure.
