AB: The snowballing effort to establish environmental observing systems will (is already?) overwhelming our ability to maintain accurate instrument metadata from acquisition through archiving and delivery to end users. Traditionally this issue has been addressed by labor intensive and sometimes relatively ad hoc approaches typified by custom, proprietary, poorly documented data systems based on simple asynchronous point to point protocols such as RS-232. While there is a broad range of "standards", many of which have demonstrated effective use such as the Serial Ascii Instrumentation Loop (SAIL), NMEA0183, and SDI-12 to name a few, but none that have been widely implemented across disciplnes due to a not well characterized collection of barriers. Currently evolving efforts including IEEE-1451 and the MBARI-led PUCK effort show signficant promise. In the context enhancing the reliability of an evolving shipboard data acquistion system a number of options are being explored in order to clarify these barriers with the intent of removing at least some.
