Abstract

By exhaustively reviewing the literature related to marine geohazards, this paper reports on their uncertainties. Examples of marine geohazards include submarine landslides, fluid flows in the underground, scour events, and seabed gouging by ice. Key uncertain variables of interest to marine geohazard assessments are identified and structured by relating a framework defining the main generic components of any risk description to the task of describing risk in the marine geohazards field. Furthermore, issues related to the sources of uncertainty are scrutinised and some recommendations on how to address the identified large uncertainties in geohazard risk assessments are made. Specific considerations are proposed for analysing geohazards in the Arctic, where exploration and development activities are currently regaining momentum. Ultimately, based on the large uncertainties identified, we also strive to identify knowledge gaps to orientate scientific research efforts in the field of marine geohazards.

海洋地质灾害暴露:涉及不确定性

摘要

通过详尽回顾与海洋地质灾害相关的文献,本文报告了它们的不确定性。海洋地质灾害的例子包括海底滑坡、地下流体流动、冲刷事件和海底冰刨。通过将定义任何风险描述的主要通用组件的框架与描述海洋地质灾害领域风险的任务联系起来,识别和构建海洋地质灾害评估感兴趣的关键不确定变量。此外,对与不确定性来源相关的问题进行了审查,并就如何解决地质灾害风险评估中已确定的较大不确定性提出了一些建议。为分析北极的地质灾害提出了具体考虑,目前北极的勘探和开发活动正在恢复势头。最终,
