Percentage of sand content provided in 10 cm intervals down the length of 186 sediment cores collected in San Francisco Bay, California in 1990-91, 2000, 2006, and 2016. Sediment data were obtained from a combination of gravity, box, and push cores ranging in length from 14 to 360 cm. Sand content percentages were obtained from a compilation of visual analyses, descriptive and graphical core logs, and grain size measurements. For the purposes of modeling variability in sand content with depth beneath the ...
