| Abstract: | Submarine canyons on the northern margin of the Bay of Biscay have been viewed with side-scan sonar at slant ranges carying from 1 km to 22 km. First results indicate the importance of secondary gullying, and that while published charts may show the correct number of canyons the trends are sometimes more oblique to the regional slope than shown (probably fault-controlled). In general the similarity to subaerial fluvial drainage patterns is striking. |
