Fig. 6. Aerial infrared image,
(2125-2305 IMT) 26 August
1968, of Kverkf jöll area showing
thermal features of Hveradalur,
Kverkfjöll couloir and glacial
outlet tongue as well as thermal
melt-water drainage from Kverk-
jökull, as in 1966 image. Note
bright thermal pattern from
north rim of ice cauldron, part-
ly obscured by electronic defects
of the image. Emission from
cauldron appears somewhat di-
minished since 1966. Differences
in linear distortion between
1966 image (Fig. 4) and this
view result from slightly differ-
ent aircraft flightlines and mis-
match between apparent ground
speed of aircraft and film trans-
port mechanism. Bright bands
across image are also electronic
defects.
