This indicator records the amount rock extracted and crushed for infrastructure needs at Casey, Davis and Mawson stations. Included are some details of the blast burden and pattern.
TYPE OF INDICATOR
There are three types of indicators used in this report:
1.Describes the CONDITION of important elements of a system;
2.Show the extent of the major PRESSURES exerted on a ... system;
3.Determine RESPONSES to either condition or changes in the condition of a system.
This indicator is one of: PRESSURE
RATIONALE FOR INDICATOR SELECTION
oncerns have been raised over time by a number of station personnel about environmental impacts of quarry operations at Australian Antarctic Stations as well as impacts on local breeding populations of snow and wilson's storm petrels. Documenting quarry operations is therefore of interest to ensure that agreed quarry boundaries are adhered to along with regulatory non-blast
periods to avoid disturbance to petrels during their incubation period.
DESIGN AND STRATEGY FOR INDICATOR MONITORING PROGRAM
Spatial Scale: Australian Antarctic stations: Casey, Davis and Mawson.
Measurement Technique: Visual
Previously, documentation has rarely been kept and communication of responsibility has been patchy. Anecdotal reports of deficiencies in past management of quarries and non-conformance to the AAD's policies stated in 'Quarrying in Antarctica, an environmental policy statement' (1996) has prompted a new effort to gather data to ensure the AAD is meeting environmental and legislative obligations and is satisfying public expectations for sound environmental management of Australian activities in
