海底电缆系统（OBCS）是监测孕震带构造活动的最佳方案。然而，由于成本高昂，现有OBCS的地震仪数量不足以进行高分辨率的发震带观测。为了降低OBCS的成本，作者与各领域的工程师共同深入研究了现有OBCS的成本分析，明确了降低系统成本的关键因素，并对新OBCS的成本进行了估算。在此基础上，作者设计了两种新型的高性价比obcs。
An ocean bottom cable system (OBCS) is the best solution for monitor the tectonic activities in a seismogenic zone. However the number of seismometers of the existing OBCS is insufficient for high resolution observation of the seismogenic zone, because the cost has been very expensive. In order to lower the cost of OBCS, authors have studied cost analysis of existing OBCS in depth jointly with engineers of various fields, and specified the key factors for lowering the cost in system, and estimated the cost of new OBCS. Authors have designed two types of new cost effective OBCSs based on this study.
