Summary
Abstract: Metadata record for data from ASAC Project 115
See the link below for public details on this project.

From the abstract of the referenced paper:

Umbilicaria decussata, Usnea sphacelata, Ceratodon purpureus and surface soil samples were collected at 10 m intervals for 90 m downwind of a concrete batching site at Casey Station, East Antarctica. Comparable samples were collected from a similar uncontaminated remote site (SSSI 16 - now known as ASPA 135). Surface soil was alkaline in the immediate vicinity of the batching site (max pH 8.8) and tended to decrease with distance. In the SSSI control site, surface soil was acidic (pH 4.7). Lichens growing downwind of the batching site were more susceptible to damage from airborne alkaline pollution than the mosses and were moderately to severly bleached. This chapter describes the relation between mean total cholorphyll concentration, chlorophyll a/b ratio, distance from the batching site and soil pH. Low temperature (77 K) fluorescence of healthy plants from the SSSI and polluted plants 40 m downwind of the batching plant were compared. Variable fluorescence, indicative of photosynthetic electron transport was observed in all cases, from which we dedice that even severly bleached lichens contain live algal cells. The results presented provide quantitative baseline data against which further change (recovery or further deterioration) can be measured.
