Geoland
| The Walcott Bay area has a complex geology with basement rocks, small volcanic cones and an extensive drift mantle which include a wide range of rocks; the |
| area was previously covered by the Koetlitz Glacier which has retreated; lower altitude surfaces are late Ross Glaciation in age |
Descr
| Walcott Bay, at the eastern edge of the Walcott Glacier; approximately 200m from the southern margin of Walcott Glacier and 4km from the Koetlitz Glacier; a |
| low lying depression forming a salty hollow; the samples are a 4 points on the floor of the depression to see if there are microbiological differences associated |
| with site wetness and salinity |
