Our calculations indicate that heat fluxes of up to 1MWm2 may be obtained when the bulk vapor in the cavity is in free convection. This is considerably smaller than heat fluxes inferred from ice penetration rates in recent subglacial eruptions. Forcing of the convection by momentum transfer from...
Layer prominence provides a qualitative proxy for the degree to which the melt layer may present a bulk, macroscopic (>20 m horizontal scale) impediment to vertical percolation of meltwater by reducing the number of high permeability drainage pathways through the firn21. Further, the quantitative...

Greenland's ice melt is of particular concern, as the ancient ice sheet holds enough water to raise sea levels by at least 20 feet (6 meters) if it were to melt away entirely. The study adds to evidence that Greenland's icy bulk is melting more quickly than anticipate...
The growth rates for bulk sea ice were found to be of the order of 10~(-7)m s~(-1),an order of magnitude less than the rates for the individual platelet ice crystal. The residual of the energy balance suggested that a negative oceanic heat flux (i.e., heat transport down into ...
Stibal et al.134found very different bulk and active bacterial communities. By comparing the bulk DNA with the potentially active RNA community, Stibal et al.134provided evidence that, although the gene pool in cryoconites is more diverse at the margins, reflecting the contribution of organisms fr...

Evidence for the presence of sedimentary OM beneath ice sheets is found in the preservation of ancient paleosols in basal sediments and bulk meltwaters of the Greenland Ice Sheet98,99 and the presence of marine sediments and their geochemical influences beneath the West Antarctic Ice Sheet and ...
For high-latitude oceans, sea ice effects must be considered since the sea-ice-derived meltwater is an additional surface buoyancy source, and the presence of pack ice largely hinders direct wind influence on the mixed layer. To quantify the roles of wind mixing, atmospheric buoyancy input, and...
