  3. How accurate are the heights or depths?

    Water depth determination technique not noted in report. Water depths given in meters.

  4. Where are the gaps in the data? What is missing?

    All available textural, statistical, and compositional information are included in usSEABED. . The Holmes compilation may also include metal and organic contaminant values requested by or performed by the EPA, USGS, USACE, and others for these samples that are not included in usSEABED.

  5. How consistent are the relationships among the observations, including topology?

    Data fall within normal ranges for the given parameters.
