  Comments: Row 1 x 108, y 4, y 17. Sparse slide. Only 13 diatoms found along a whole transect. A full count would not be reached by time limit. Continued count: Row 2 x 109, y 17, y 2, Row 3 x 108, y 2, y 17, Row 4 x 107, y 17, y 2, Row 5 x 105, y 2, y 17, Row 6 x 104, y 17, y 2, Row 7 x 103, y 2, y 17. Sparse sample.
