more algae, higher altitudes, flushed at lower

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

Darkening of ice reduces albedo and increases melt

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

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

solute conc cryoconite holes = respiration autumn, photosynthesis summer

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

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

subglacial lake = low nutrient, low microbial diversity

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

Warming up, microbes up
