This report describes a multiple CZ acoustic telemetry experiment conducted off the coast of California 1/28/90-2/2/90. The goal
was to design a maximally robust high speed underwater modem suitable for data telemetry for submerged platforms and moorings.
Six modulation methods were used to transmit data at rates from 1 to 1000 baud corresponding to bit rates up to 3kbit/sec.
In addition, a large number of channel probe sequences was transmitted in order to estimate channel multipath, fluctuation
dynamics and spatial diversity characteristics relevant to acoustic data telemetry.
The data was transmitted from a 1 kHz source suspended from the R/V McGaw, and received on a multichannel vertical array
tended by the RV Point Sur. The multichannel data was digitally recorded using floating-point digitizers and stored on optical disk for further processing. Approximate transmission ranges were 70, 140, 200 and 250km. Approximtely 8 hrs of transmission were recorded at each data range.
