Depthppm reduces the complexity of the depth data by assigning one color to a range of depths. The relationship between depth ranges and colors is given in the source code file depthppm.c. Included in the data set is a table enumerating the days for which sea-surface temperature data were available in the source material. In general, images were available every week during the time period from 811001 through 891231. Included in the data set are the UNIX shell scripts and makefiles that were used to derive the averages and create the tables and images.
