"Variable-depth profile collection"@en . . "SDN:C10::VPRFCOLL" . "The series has a set of measurements along a trajectory (variable times and locations) at multiple depths that can possibly vary from measurement to measurement. Each measurement constitutes a spectrum with a non-spatial variable (generally bin number) on the secondary (rank 0) dimension. The primary (rank 1) dimension includes position and time variables. The z co-ordinate (depth or height) is carried with the data variables as 2D (rank 2) arrays."@en . .
