eter) and 0.4000.700 m (total photosynthetically active radiation). These
radiometers operated automatically and recorded data in one-minute averages
continuously throughout the cruise.
The second component consisted of the shipboard satellite tracking facil-
ity, the TeraScan system manufactured by the SeaSpace Corporation. In addi-
tion to providing weather and ice navigation for the expedition, the satellite
tracking enabled this project to measure energy reflected and emitted to space
at the same time that the shipboard instruments were measuring solar and
terrestrial radiation impinging on the Arctic Ocean surface. The TeraScan sys-
tem was used to track NOAA polar-orbiting satellites, obtaining 1.1-km spatial
resolution images from the advanced very high resolution radiometers
