Bioluminescent Patch Detected By Radar

June 20, 1977. m.v. Gambada. The Gambada was sailing from Santos to Buenos Aires. Unusual echoes were observed on the radar screen. What was thought to be a patch of rain on the radarscope moved toward the vessel against the wind. The radar echo of the patch had a distinct edge to it unlike those of the other rain areas. Yet, when the ship was at the center of the patch there was no precipitation. Throughout the watch, however, the sea was strongly luminescent.

Reference. Several other radar observations of bioluminescent areas are catalogued in Section GLW in our Catalog: Lightning, Auroras, Nocturnal Lights. For more information on this book, visit: here.
