One of the particularities of being in Qikiqtarjuaq, and evidently of being beyond the polar circle, is the time and more precisely: the timing.
Ice coring, a central activity at the Ice Camp
One of the major habitats GreenEdge researchers are studying is the sea-ice. We are interested in its optical, physical and chemical features, as well as the life it supports. As such, one of the essential activities at the ice camp is the ice coring. We actually spend the full morning coring the entire ice thickness (which currently varies from 1.15 m to 1.50 m at the study site) with different cores (14.5 and 9 cm diameters) for different purposes, i.e. measurement of temperature and salinity gradients, nutrient content, chlorophyll a biomass, spectral properties, microbial genetic diversity, etc.
Prokaryotic heterotrophs play a key role in marine global carbon fluxes by way of their consumption of dissolved organic matter, respiratory CO2 production and nutrient recycling activities.
