Abstract
Published analyses of 61 piston cores, bottom photographs, and dredge samples provide ground truth for 6.5 kHz GLORIA side-scan sonar records of the Mississippi and De Soto fans. GLORIA sound appears to have penetrated through up to 4 m of foraminiferal ooze and terrigenous mud to reach sandy sediments. Possible primary geological causes of high backscatter include slump structures at various scales (1->1,000 cm), possible debris flow fabrics (roughness 1–100 cm) in sandy (5–21%) sediments, and thin ironstone crusts with a roughness of tens of centimeters.
