There are four record types: 1)station; 2)analysis; 3)statistics and 4)comments. For each sample there is a station record followed by a variable number of analysis records, followed by a statistics record and possibly followed by a comment record (there may or may not be a comment record for each sample). Each physical record on the tape contains 2000 bytes and consists of 25 logical records as described. Surficial sediment record type 1 station/sample: Field name Col. Len.
