“…The general summary of key soil properties in the Ross Sea region indicated that the material is predominantly gravelly sands with a singlegrained structure (Affleck et al 2017;Balks et al 2013). The predominant geologic features of the ice-free surface of McMurdo Station are characterized as basaltic and pyroclastic flows interbedded with widespread tills (Cole et al 1971). In general, the fractured rocks and boulders are classified as (olivine-augite) basalts (Cole et al 1971) at Fortress Rock, Arrival Heights, and Crater Hill, including trachytes rocks at Observation Hill (Figure 1).…”

In general, the fractured rocks and boulders are classified as (olivine-augite) basalts (Cole et al 1971) at Fortress Rock, Arrival Heights, and Crater Hill, including trachytes rocks at Observation Hill (Figure 1). Because Fortress Rock, Arrival Heights, Crater Hill, and Observation Hill are within 1 km of each other, the general description of the surface geology of McMurdo Station is varying amounts of scoria and basalt fragments in ice matrix and fractured basalt bedrock.…”

The plan to modernize McMurdo Station involves constructing large buildings for more efficient facilities and infrastructure. Foundation design for these large buildings will require understanding of the mechanical properties of the native soil. This study is the first that we are aware of to conduct uniaxial compression tests on materials from McMurdo Station in their frozen state. The testing used in this study emulates specific ground conditions measured on-site. Reconstituted specimens of well-graded gravel basalt were compacted at 4% and 20% by weight moisture contents and frozen at temperatures of −7°C and −20°C. Test results determined that higher moisture content combined with lower ambient temperatures resulted in increased strengths compared to optimum moisture and compaction testing results. If new building foundations will be in direct contact with the ground and allow heat transfer to take place, then the base material should be placed and compacted at the optimum moisture content. This will reduce the potential effects of thaw degradation under the foundation, especially on icerich ground.

“…The ice-free ground at Cape Crozier is of volcanic origin, with numerous small cones and craters evident among gentle slopes of scoria and fine-grained basalt lava. Phonolite cones at Post Office Hill and The Knoll are 1.4 million years old, while other volcanic rocks in the area are less than 1 million years old (Cole et al 1971;Wright & Kyle 1999). Several of these hills, including Post Office Hill, shelter the penguin colonies from southwesterly winds.…”

The bryoflora of Larsemann Hills oasis (Princess Elizabeth Land, Antarctica) was investigated. Six moss species and one liverwort, Cephaloziella varians, were recorded during field studies over the period 2009–2014. Bryum archangelicum Bruch et Schimp. is new for Princess Elizabeth Land and three species [B. archangelicum, Bryoerythrophyllum antarcticum (L. I. Saviz et Smirnova) P. Sollman and Syntrichia sarconeurum Ochyra et R. H. Zander] are new for Larsemann Hills. Representative specimens are listed and data on habitats and associated species provided. The most common mosses in the area are Bryum pseudotriquetrum and Coscinodon lawianus. Bryum pseudotriquetrum was found for the first time in Larsemann Hills at the bottom of lakes.
