infr;irzd line bCiiililing system (Line Scanner. Model DEI-I200, made by
Daeduls Co. Ltd., USA.) was installed on the airplane, a Cessna 207. The
system was free from undesirable movement of the plane within & 5' by the
aid of a gyroscope. The main characteristics of the system are shown in
Table I.
Close attention was paid in order to keep the plane on its right course
with a prescheduled constant velocity. A series of flights at an altitude of
loo0 m above sea level was stirrted at about 1O:OO JST, August 19. 1972.
After some processing, the data were displayed like an aerial photograph of
different coloration according to the energy intensity of the radiation.
namely. the temperature of the sea surface.

Alter comparison with an cxisting precise map. some correction w a s made
of the picture which was a little distorted due to unavoidable swing and
spced change of the plane. The surface temperature distribution is depicted
in Fig. 1.
For reference. meteorological data near the site at the time of the Right
were as follows: weather: clear; wind: 7.2 m s - ' SW, temperature: 30.1 'C.
As shown in Fig. I, the . x axis is taken on the sea surface along the center
line of the plume of thermal pollution. with they axis perpendicular to the .Y
axis. The lalerol spread of the plume is then obtained every 100 m from the
soiircc along the center line. Readings are tabulated in Table 11. lo the right
and left separately.
