Geosonnet 44



Antarctica’s a frozen realm of ice
Yet troglodytic hydrospheres remain
Radar reflectors, frozen lakes entice
Ice fishermen to see what they contain
Before the ice age, glacial domes were seas
Below sea sediments can still be found.
The lake is mostly glac’ers which unfreeze
Trapped ocean water seeps up from the ground.
The surface sediments are oxidized.
The sulfate in the brine is unreduced.
Lest oxygen at depth leave us surprised
Dissolved O2 in meltwater’s deduced.
   Alas, no fish were sampled by the drill
   Just microbes that an ice age couldn’t kill
