Why are values of grain size only given to 1 decimal place whereas percent sand and other data are only given as integers?
Work in the dbSEABED project has established the typical accuracies on measurements of these parameters. Those accuracies, even for careful work, are of the order of 2 to 5 percent of half the total range of the parameter. The table outputs are designed to be brief to restrict data volumes and make mapping faster and easier and to carry the data at a precision that is appropriate to measurement accuracies.
