An electrochemical study of lead-borate complexation in 0.7 M NaClO4 at I = 0.7 M and 25°C

Borate complexation of lead was found to be much weaker than suggested by data in the literature. Assuming a complex PbB(OH)₄⁺ we estimate log β < 3.5. Borate complexation of lead in seawater is calculated to be negligible (<0.5%)     

Acoustic telemetry system for underwater control

Underwater acoustic communication in the multipath environment encountered in shallow water is restricted mostly by signal fading. It degrades the signal detection and time synchronization required for reliable acoustic communication. An approach to time synchronization and to the frequency diversity method is presented. A communication algorithm for obtaining a reliable acoustic underwater link, and offering an easy-to-implement decoding scheme is introduced, and system realization is described
