Ring parameters: The first column is the ring number, D is the diameter in km, Observed is
the date when the ring was first observed in the dynamic height field, Speed is the translation
speed of the ring, Volume is the volume of the ring, Transport is the volume transport,
TQ is the temperature transport. The last row, Mean, is the mean value of the parameter.
NBCR1,2,and 4 are the NBCR cruise numbers. 1 Sv = 106 m3/sec
