Qualitative data was processed using a multiproxy geophysical and sedimentological approach, creating detailed seabed maps using bathymetric data supported by ground truthing sedimentsamples. Surficial sediment deposits display a close fit to industry standard aggregates but considerable temporal variance at depth from vibrocore analysis shows variable marine reworking over time. Marine processes off the south coast diminish the aggregate quality of reworked fluvio-glacial deposits as evidence of increased marine reworking causes the replacement of favorable coarse-grained deposits with shell fragments.
