Quarry Operations at Davis and Casey Stations, 2004-2013

This dataset was originally set up as a "State of the Environment" indicator - however, that application no longer functions at the Australian Antarctic Data Centre, so the data have been extracted and attached to this original metadata record for the indicator.INDICATOR DEFINITIONThis 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.RATIONALE FOR INDICATOR SELECTIONConcerns 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 PROGRAMSpatial Scale: Australian Antarctic stations: Casey, Davis and Mawson.Frequency: YearlyMeasurement Technique: VisualRESEARCH ISSUESPreviously, 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 inAntarctica.The fields for this dataset are:DateLocationBlastUncrushed rock removed (cubic metres)Hours of crusher operation

本数据集最初设立为环境状况指标（State of the Environment indicator），但该应用目前已无法在澳大利亚南极数据中心（Australian Antarctic Data Centre）运行，因此数据已被提取并附加至该指标的原始元数据（metadata）记录中。

指标定义
本指标记录了凯西站（Casey）、戴维斯站（Davis）与莫森站（Mawson）为满足基础设施建设需求所开采和破碎的岩石总量，内容涵盖爆破装药量与爆破模式的相关细节。

指标选择依据
长期以来，多名站点工作人员陆续对澳大利亚南极站点采石作业带来的环境影响，以及对当地雪海燕与威尔逊风暴海燕（snow and wilson's storm petrels）的本地繁殖种群造成的干扰提出了担忧。因此，记录采石作业情况有助于确保各方严格遵守约定的采石边界，并落实监管机构规定的非爆破时段要求，避免在海燕孵化期对其造成惊扰。

指标监测方案的设计与策略
空间范围：澳大利亚南极站点：凯西、戴维斯与莫森站。
监测频率：年度
测量技术：目视观测

研究议题
此前，采石作业的相关记录极少留存，责任划分与沟通也较为零散。有传闻指出，过往采石管理存在诸多缺陷，且未遵守澳大利亚南极数据中心1996年发布的《南极采石作业：环境政策声明》（"Quarrying in Antarctica, an environmental policy statement"）中的相关规定。这一情况推动我们重新开展数据收集工作，以确保澳大利亚南极数据中心能够履行环境与法律义务，并满足公众对澳大利亚在南极活动实施合理环境管理的合理期待。
