Definition of Rank

  • Rank 1 is a one-dimensional parameter
  • Rank 2 is a two-dimensional parameter
  • Rank 0 is a one-dimensional parameter describing the second dimension of a two-dimensional parameter (e.g. bin depths for moored ADCP data)

Narrative Documents

AML Conductivity Temperature Depth profiler CTD-12

A self-contained CTD with platinized 4-electrode glass conductivity cell, pressure-protected thermistor temperature sensor and a semiconductor strain gauge pressure sensor plus integral data logger. The instrument package was superseded by the AML CTD-12 plus.
