Data description

Vibracores were collected from offshore locations: Kailua only in 1997, Kailua, North Coast, Leeward coast and South Coast in 2000. In April, 1998 beach samples were collected from beaches around the island of Oahu at approximately three locations along survey lines. The Grainsize, Cumulative Grainsize, Insoluble Residue, Composition, and Abrasion data on this CDROM are presented in Microsoft EXCEL 97/98 & 5.0/95 Workbook (.xls) format, comma separated value (.csv) format and HTML(.htm) format.

Files are separated by location; Kailua, leeward (west) coast, north coast, and south coast (Waikiki). The beach data has been separated from the offshore data.

Description of Excel and HTML Sediment Properties files

Grainsize files are organized in columns representing half phi sizes from -1.0 phi to 8.5 phi and whole phi sizes from 9.0 to 12 phi. The next five columns show the percent gravel, sand, silt, clay and mud. Then six columns represent gravel/sand, sand/silt, silt/clay, sand/mud and gravel/mud ratios. the last four columns display the data First Moment, Variance, Standard Deviation and Fourth Moment. The first column represents the name of the sample.

Cumulative grain sizes are displayed in columns representing half phi sizes from -1.0 phi to 8.5 phi and whole phi sizes from 9.0 to 12 phi. The first column represents the name of the sample.

Composition data is displayed in columns representing percent forams, coral, mollusk, halimeda, bryozoan, echinoderm, coralline algae, shellfrags, and other. The first column represents the name of the sample.

Abrasion data is described in percent reduction in the second column. The first column represents the name of the sample.

Insoluble residue files describe each sample in percent organics and percent residue.

Description of Excel GIS files

Latitude and longitude data is provided in columns aligned with data attributes to allow mapping of the data.
