IOOS Convention for observation data encoding in CSV/TSV

CSV means that the data are expressed as a sequence of multiple data values or metadata attributes separated by commas on a single line of text. Each line of text represents a single point in time and space. Multiple lines are used for additional times or locations. CSV data can be thought of as an array of rows (one per line) and columns (one per value in each line). TSV means that the data are expressed as a sequence of multiple data values or metadata attributes separated by tabs (ASCII character 0x09) on a single line of text.
