For the past three decades, the VACM has been a standard for ocean current measurements. A VACM is a true vector-averaging instrument that computes north and east current vectors and averages temperature continuously over a specified interval. It keeps a running total of rotor counts, and records one-shot samples of compass, vane position and time. Adding peripheral sensors to the data stream was easy. In today's economy, it seems imperative that operational centers concentrate on upgrading present inventory rather than purchasing newer instruments that often fall short of the flexible measurement platforms with high data capacities required by most researchers today. PCMCIA cards are rapidly becoming an industry standard with a wide range of storage capacities. By upgrading the VACM to a PCMCIA storage system with a flexible microprocessor, the VACM should continue to be a viable instrument into the next century. > |
