Electronic Supplementary Material
Digital Raman spectra and images of the sediment grains are provided for the data
shown in Figures 4, 6 and 8. The Raman spectra are grouped by lake and the
spectrum numbers in the digital file are the same as those used in the figures.
Figure S1 (filename = Bishop et al LFR-1 sediment grains)
This view of several grains from sediment 1 from Lake Fryxell (sample JB 651)
illustrates the variety of grain shapes, sizes and colors. The yellow dishes are ~0.5
cm in diameter. All spectra shown were collected on grains from position 1 (yellow
dish marked by 1).
Figure S2 (filename = Bishop et al LVA-9 sediment grains)
This view of several grains from sediment 9 from Lake Vanda (sample JB 669)
illustrates the variety of grain shapes, sizes and colors. The yellow dishes are ~0.5
cm in diameter. Spectra 1 and 2 were collected on grains in position 10, while
spectra 3 and 4 were collected on dark grains in position 3.
Figure S3 (filename = Bishop et al LBR-2 sediment grains)
This view of several grains from sediment 2 from Lake Brownworth (sample JB 671)
illustrates the variety of grain shapes, sizes and colors. The yellow dishes are ~0.5
cm in diameter. Spectra 1 and 2 were collected on different locations of the same
particle in position 2, while spectrum 3 was collected on a dark grain in position 3,
and spectrum 4 was collected on a light grain at position 11.
