Table 1 Properties and expected characteristics of five Antarctic subglacial lakes.

The last column is the predicted maximum diameter of particulates maintained in suspension in the mixed bulk by the large-scale circulation of vertical convection (see Discussion section). Geophysical characteristics are obtained from (2, 9, 10, 16, 57, 58), while flow conditions are derived from scaling laws discussed in the Results section of the main text and described in detail in the sections, “Scaling laws for nonrotating vertical convection” and “Scaling laws for rotating horizontal convection,” in the Materials and Methods. Ice drop refers to the difference in ice thickness above the lake due to the mean slope of the ice-water interface.
