were made with a towed temperature probe located 100 feet below the surface. Hourly in- 

 jection temperatures were also recorded. A flight was made along the ship's track on 26 

 January. After overtaking the CASCO, the aircraft flew at various altitudes over the ship 

 while simultaneous measurements were made from the ship with a Barnes model IT-1 in- 

 frared thermometer (IRT). The meteorological and oceanographic conditions during these 

 flights are shown in table 1. The temperature-distance profiles for probe and ART meas- 

 urements are shown in Figure 4.
