Abstract: Metadata record for data from ASAC Project 36
See the link below for public details on this project.
From the abstract of one of the referenced papers - &Environmental conditions and microbiological properties from soils and lichens from Antarctica (Casey Station, Wilkes Land)&:
Microbial habitats of an Antarctic coastal terrestrial environment are described. Emphasis was laid on soil with ... different contents of organic matter and some representative lichen species. Parameters for this description were microclimatic conditions, organic and inorganic matter, epifluorescence microscopy, and parameters describing microbial and enzymatic activity. The data of direct measurements of bacterial standing stock (number and biomass) and of exoenzymatic activity via FDA-hydrolysis were found to be the most valuable parameters for microbiological properties. The data show significant differences with regard to nutrients and microbial activity. Scales of patches are only a few square decimetres with wide ranges of environmental and microbiological properties within short distances.

From one of the referenced papers - &Environmental conditions and microbiological properties...&:
Emphasis was laid on environmental conditions (temperature profiles, humidity and light) of two different soil environments and corresponding microbiological properties: ... Soils with relative high and low amounts of organic matter and four different lichens which were chosen as representative plants of this area. Sampling and data recording was carried out within an area of 20 x 20 m.
Temperature, relative humidity (rH), and light (photsynthetic active radiation (PAR) were recorded with &Squirrel& data logger. Temperatures were measured with microthermistor probes, humidity as measured with &Humicap& probes and light with &GaAsP& photodiodes equipped with filters for PAR.
