The ridge and trough province is an eroded and dissected foreset sequence that occurs along a 5 to 9 km wide-zone on the upper slope off southwest Florida. Observations from the submarine NR-1 show a series of three parallel ridges and intervening troughs within a water depth range of 384 to 436 m. Ridges consist of a series of vertical (or nearly vertical) sedimentary outcrops, each capped with what appears to be a manganese/phosphorite and/or limestone layer, and separated from one another by terraces of various widths. Contrary to previous speculation, no evidence of faulting was found. While the absence of rock samples precludes determination of age or composition of the sedimentary strata, it appears possible that these outcrops represent a continuation of the mid-Tertiary phosphoritic sequences found on the Pourtales Terrace and Blake Plateau.
