Appendix 2 - Sediment Texture

Sediment texture analyses for all samples obtained in this study are presented in a summary table below and in a downloadable Excel spreadsheet (table A2.1 Excel format). The location of these samples and the texture data are also available in the Geographic Information System (see Appendix 1) where they can be viewed with other geologic data. See Map Sheet 5 (PDF format) for sediment texture superimposed on backscatter intensity. Photographs of the sea floor obtained at these stations are available in Appendix 3.

See Poppe and others (2000) for a description of the procedures for sediment texture analysis. Hastings and others (2000) provide a data dictionary describing the column headings in the Excel spreadsheet.
