Figure 6

Inflow of subglacial meltwater containing solid-phase materials and dissolved nutrients, including silica, relic carbon, and nitrogen. Schematic models of (a) past lake setting after glacial erosion (i.e., the initiation of sedimentation processes during the marine phase) and (b) present lake setting (lacustrine stage). The relative sea level is controlled by glacio-isostatic uplift. For the present sea ice conditions during the summer season (December 2005; photograph taken from a helicopter), please see the description of the landscape of Rundvågshetta (Additional file 1).
