EPA-IAG-DS-E693-EO Analytical methods: clay mineralogy. Bottom sediment - grab samples. particulate matter - Niskin Bottle and 0.45 micron millipore filters. Oriented & random specimen, X-ray diffraction. Relative peak areas & weighing factors. There are two record types: 1)station and 2)sample For each station there is one station record followed by a variable number of sample records. Each physical record on the tape contains 2000 bytes and consists of 25 logical records as described. Clay mineralogy record type 1 station: Field name Col. Len.
