a Selected isopycnal densities are listed in the first column, and the second, third, and fourth columns list the mean isopycnal depth, potential temperature, and salinity. The fifth and six columns list the RMS errors in isopycnal density and depth tracking (see text for discussion). The seventh, eight, and ninth columns list the RMS spicy sound-speed variations along the selected isopycnals for temperature, salinity, and sound speed. These last three statistics only include contributions from frequencies between the Coriolis frequency, f, and a typical value of buoyancy frequency, N. For brevity, only every other isopycnal is displayed here.
