description:

reason:
  Long Term Ecological Research (nematode experimental area) site investigation of soil properties; this site (LTER 10) was chosen for daily repeat sampling to see if there were measurable changes in soil moisture over the length of the sampling period

description:
  Elevational transect A Plot, on the south side of Lake Hoare, approximately 100m south of Lake Hoare, and 150m east of the LTM Datalogger Plot; on the upper part of a shallow sloping gravelly basin surface; the sampling site was on the south and upslope side of the Elevational Transect A Plot; the area comprises shallow northward sloping, somewhat bouldery ridges separated by depressions with fine gravelly surfaces; this sampling site is immediately adjacent to LTER 10b and is designated LTER 10c

geological_setting:
  The deposit is unweathered Ross I till, possibly derived from the Canada Glacier but almost certainly with an up-valley influence because of the presence of marble clasts from basement rocks; the tills may be fluvio-glacial owing to complex depositional ice-marginal processes as the sand % generally increases downwards while there are noticeably more coarse clasts at the surface; some weak sedimentary bedding

soil_parent_matterial:
  Sandy pebble gravel to sand; predominantly granite (40%) gneiss, dyke rock, dolerite and volcanic (scoria)

biological_activity:
[cell repeats an earlier one in this file: 116 characters]

surface_weathering:
  Nil surface staining, pitting and exfoliation; some clasts slightly oxidised, probably from pre-weathering; weak ventiforms and a well developed pebble pavement; moderate rounding; many carbonate coatings on undersides of surface clasts

description:
  Approximately 1.2k south of Lake Hoare and 2.1km ESE of Suess Glacier; on a sloping ridge surface; a broad undulating ridge surface with minor knolls; the site is several metres below a small knoll

geological_setting:
  Bedrock (granite, schist/gneiss, dolerite) outcrops on the ridge in places but the ridge is mostly covered with till; the till appears older than Ross I, perhaps equivalent to weathering stage III; the presence of basalt clasts indicates an age younger than the basalt outcrops in Taylor Valley; some very large granite erratics occur further to the west

soil_parent_matterial:
  Mixed lithology sandy stony gravel till (granite 40% up to 1.2m, gneiss 25% up to 45cm, dolerite 20% up to 30cm, basalt 5%)

surface_weathering:
  Weak to moderate surface staining; some pitting and moderte to strong exfoliation; moderate to strong ventiforms and ssome weaak polish; many clasts angular to subangular but some subrounded; weak carbonate coating but distinctive salt accumulations beneath surface stones

previous_disturbance:
  Some old footprinting and soil pit examination sites in the general vicinity but nil observed at the site

geological_setting:
  The deposit is unweathered Ross I till, possibly derived from the Canada Glacier but almost certainly with an up-valley influence because of the presence of marble clasts from basement rocks; the tills may be fluvio-glacial owing to complex depositional ice-marginal processes as the sand % generally increases downwards while there are noticeably more coarse clasts at the surface; depressions typically have sandy pebble deposits

soil_moisture_status:
  Xerous to subxerous; the soils in the depression are moist to the surface; the increased moisture content may partly be a function on higher salinity

description:
  The southern end of Arena Valley, about half way between Taylor Glacier and Alter Mountain, on low hummocky moraine near the foot of a short low snow covered slope; the site area is gently undulating with scattered fragmented large (1-2m) dolerite boulders; the surface has a patchy appearance with variable amounts pale sandstone or dark dolerite at the surface

geological_setting:
  Arena Valley is a very old valley with Miocene aged tills on the valley floor; the tills generally become younger to the north having been derived through advances from Taylor Valley; the local rocks are Beacon Sandstone and Ferrar Dolerite; these are present in the till which appears to be locally derived as there is no sign of any erratics

soil_parent_matterial:
  bouldery sandy till from dolerite and sandstone with the fine fraction mainly derived from sandstone

surface_weathering:
  A cobble boulder pavement with some upstanding (75cm) fragmented dolerite; strong staining on dolerite with some pitting and exfoliation on corse grained clasts; strongly developed ventiforms; well developed polish and some rounding due to abrasion; thick salt accumulations beneath many surface clasts

description:
  A bouldery surface, nearly all dolerite with some up to 2m but most >75cm; part of a gently northwards sloping, broad till plain valley floor; the surface is intermediate in age with younger till surfaces closer to the Taylor Glacier and older till surfaces at higher levels on the valley side; the ground surface is uneven with slight bouldery hummocks or rises separated by small flattish smoother patches; accumulations of pebble and granules in the lea of some boulders

geological_setting:
  Beacon Valley is a very old valley with Miocene aged tills at higher levels in the valley; close to the glacier there is a series of well marked younger recessional moraines with granitic erratics indicative of earlier ice advances up valley from Taylor Glacier; granite erratics also occur in the old tills at higher elevations; the locally outcropping rocks are Beacon Sandstone and Ferrar Dolerite; these are present in the till which appears to be locally derived at this site as there is no sign of any erratics

soil_parent_matterial:
  Sandy till from predominantly dolerite (70%) and sandstone, with dolerite boulders appearing to occur mainly on the surface and covering 20-30% of the surface

surface_weathering:
  Dolerite clasts strongly stained; some pitting on fine grained dolerite and moderate exfoliation on coarse grained dolerite; moderate to weak ventiforms; some polish on sheltered rock faces; moderate rounding from surface exfoliation; a few salt patches under some clasts
