Isle of Wight shoals used vibracore data collected in 1992 & 1997, volumes were calculated in 2000 (Conkwright, Williams and Christiansen, 2000). Borrow Area 2 has been virtually exhausted by dredging. Between 1988-1992, ~2.9 million m^3 was dredged from Borrow Area 2, ~4.2 million m^3 dredged from Borrow Area 3, and ~3.2 million m^3 dredged from Borrow Area 9 (Wells, 1994). Revised volumentric estimations for Shoals B, C, D, Little Gull Bank & Great Gull Bank (1996) \"In the 1993 sand resources study (Conkwright and Gast, 1994b) the seismically defined ravinement surface was used as the lower structural boundary for volume calculations. However, the purpose of the current study is to estimate only the volume of sand with measured physical parameters. Therefore, the lower boundary for volumetric calculations was determined primarily by the grain size parameters of vibracore samples. The lower boundary surface was set at the depth where the sampled sand became too fine or too poorly sorted for use as beach fill. In those cases where the entire length of core contained usable sand, the boundary surface was set at the depth of maximum vibracore penetration. Because vibracore penetrations on Little and Great Gull Banks were generally within a meter of the ravinement surface, that surface was used as the lower boundary for those shoals, unless vibracore samples indicated otherwise.\" (Conkwright and Williams, 1996).

study area in order to determine their potential use as a source of sand for beach nourishment. Studies conducted by MGS of Fenwick, Weaver, and Isle of Wight Shoals show four general patterns of substrate conditions: 1) Shoal crest - generally is restricted to the undisturbed shoal crest at depths less than 35 it (11.2 m) and, has no discernable bedforms; Shoal crests consist of sand with almost no shell material; Coarser gravels are concentrated in areas of greatest wave and current energies, such as along the shoal crest. 2) Flank- bottom class associated With the shoal crest; primarily found along the shoal flanks between -35 ft and -40 ft, representing transitional bottom, from shoal crest to intershoal bottom type; sand, the texture of which may or may not be significantly different than that of the shoal crest; occasional ripples; sand with some shell and other biogenic materials. 3) Intershoal-associated with the deeper sea bottom (> 40 feet), both disturbed (dredged) and undisturbed intershoal areas or troughs; sandy bottom dominated by small ripples (< 0.40 meter widths); sand with richer but not abundant benthos. 4) Patch \u2014 occurring in the deeper sea bottom (> 40 feet) in trough or intershoal areas; large patches, ~l00 it in diameter, associated with rippled bottom within the dredged area; interpreted to be soft, finer-grained sediment based on low backscatter intensity return; Patch-mat regions occur between shoals that have muddy substrates, abundant patches/mats of worm tube colonies, and shell beds.
