Isotherms of north-south CTD transects. Selected stations
of CTD transect labeled (NS14, NS6, NS3, and NS0) and the location of the
thermistor chain (T). Reference temperature of 26.7 °C is labeled
and plotted as dashed isotherm.
As the upper figure, for the east-west CTD transects.
Drogue measurements near the boat were done from 1800-1840 h 25 April and
1100-1135 h 26 April are illustrated with both direction (º from N)
and velocity (cm s-1).
