For d326: 1980-1987 was sampled at 0.5 m depth, afterwards was sampled at 2 m depth. This is not quite the same breakdown of the four separate data tables, where the first table ran 1980-1984 and 2-4 ran the rest of the dates. I check a book for reference, and it said 0-2 m was considered shallow for a lake, so I think it's ok to combine these different sampling methods. Please confirm.
Additionally, 1980-1981 was sampled at a smaller volume (6 L rather than 10) so I can scrap those years.
