The analysis of sediment texture for 98 sediment samples collected in this study is presented in a summary table in comma-separated value (*.csv) format (CCB_SedSamples.csv), which can be accessed with any text reader. These data are also available in appendix 1 (Geospatial Data) as an ESRI shapefile. See Poppe and others (2005) for a full description of the procedures used for the analysis.
