Ice algae abundant below the snow line. moves with the line

P released = Mississippi = 400,000tons p/yr

solute conc cryoconite holes = respiration autumn, photosynthesis summer

Glacier bed: aerobes o2 from o2 rich basal melt of supraglacial melt

Warming up, microbes up

Darkening of ice reduces albedo and increases melt

Volcanisms releases water full of microbes into the glacier. volcanoes under greeland and Lake Vostok (Antarctica)

Pigment Study: carotenoid pigment increased resistence to freeze thaw and solar radiation. Antarctic bacteria have increased resistance.

subglacial lake = low nutrient, low microbial diversity

3 macro environments: in vien, on grain surface, in ice crystal

more algae, higher altitudes, flushed at lower
