- W14655930 abstract "Fluctuation of late Quaternary sea level has been an important factor controlling erosional and depositional patterns on portions of the outer shelf and slope seaward of the lower-most Florida Keys. Studies in this area using high-resolution seismic, side scan sonar, bottom grab sampling, and submersible dives document a Holocene succession of lowstand wedge, transgressive, and highstand systems tract facies which have formed in response to sea level flooding the margin. The last lowstand of sea level is recorded by widespread scallop-like erosion along the slope front, occurring as deep as 150 m. Upslope from the erosional cuts, the transgressive systems tract includes a series of drowned shoreline (and reef) accumulations in the depth range 60--110 meters. Rocks recovered form paleoshorelines near 100 m water depth were submarine-cemented grainstones composed of early Holocene shallow-water carbonates. This transgressive section is partially buried by weakly laminated to reflection free fined-grained deposits of the highstand systems tract. These recent muddy silts reflect a sediment source initiated by flooding of the inner shelf platform and subsequent alongslope transport of fines exported offbank. Two very continuous, linear, and thin (< 5 m thick) paleoshorelines at 60--62 m and 66--68 m reflect a response to a changemore » in rate of sea-level rise across a low gradient surface. The deeper shoreline deposits, ranging from 75--110 m below sea level are isolated features and occur on steeper slopes. The character of preserved transgressive deposits suggests the Holocene rate of rise is punctuated. The lowest stand of sea level produced distinctive erosional features. Accretional transgressive deposits formed during the sea-level rise. Interactions between antecedent topography, bottom currents, and changes in sediment supply, slope gradients, and rate of sea-level rise are key factors controlling facies patterns, accumulation rates, and depositional geometries.« less" @default.
