Cornillon, P. REPORT ON THE USEFULNESS OF AVHRR AND CZCS SENSORS FOR DELINEATING POTENTIAL DISPOSAL OPERATIONS AT THE 106-MILE SITE. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/3-87/009 (NTIS PB87168829), 1987.
Description:
In this work data from the AVHRR sensor for 18 TIROS-N series satellite passes were examined for signs of ocean dumping at Deepwater Dumpsite 106. The passes selected occurred within five days following the actual dump although in most cases they occurred on the same day or that following the day of the dump. All spectral channels were analyzed. In addition the difference and the ratio of channels 1 and 2 were used. No dumping is evident in any of the images. If dumping is actually visible the signal must be very weak at the 1 km resolution of the AVHRR sensor. Because of this the images would have to be absolutely clear. Small scattered clouds or thick haze add too much variability to detect a weak signal. This renders AVHRR data of marginal value (if of value at all) for such work. Because the exact location of the dumps was not known it is possible that the signal is detectable.
