QICS控制释放实验表明，可以通过监测特定海洋系统内的声学、地球化学和生物参数来检测二氧化碳气体的泄漏。然而，海洋系统对（人为）渗漏的反应的自然复杂性和多变性强烈表明，没有绝对的渗漏或影响指标可以明确和普遍地用于所有潜在的未来储存地点。我们提出了一个多元的，分层的方法来监测，升级从异常检测到归属，量化，然后影响评估，根据需要。鉴于许多海洋生态系统的空间异质性，环境监测方案必须得到时间（潮汐、季节和年度）和空间分辨的数据基线的支持，从而可以准确地确定变化。在本文中，我们概述并讨论了监测方法的选择，并确定了适当的基线调查的组成部分。
The QICS controlled release experiment demonstrates that leaks of carbon dioxide (CO2) gas can be detected by monitoring acoustic, geochemical and biological parameters within a given marine system. However the natural complexity and variability of marine system responses to (artificial) leakage strongly suggests that there are no absolute indicators of leakage or impact that can unequivocally and universally be used for all potential future storage sites. We suggest a multivariate, hierarchical approach to monitoring, escalating from anomaly detection to attribution, quantification and then impact assessment, as required. Given the spatial heterogeneity of many marine ecosystems it is essential that environmental monitoring programmes are supported by a temporally (tidal, seasonal and annual) and spatially resolved baseline of data from which changes can be accurately identified. In this paper we outline and discuss the options for monitoring methodologies and identify the components of an appropriate baseline survey.
