WAVE ENERGY RESOURCES ASSESSMENT FOR THE CHINA SEA BASED ON REMOTE SENSING DATA

摘要

Wave energy is a type of significant renewable energy of ocean. In order to exploit this promising energy, it is necessary to have a full apprehension of its distribution. Remote sensing is a novel method for ocean wave observations. In this paper, based on 2009-2013 AVISO multi-satellites merged altimeter data by CNES&CLS and ESA ENVISAT ASAR observed wave field, assessment of wave energy resources were carried out. We select the South China Sea and the sea area around the Yangtze Estuary in the East China Sea as examples. Some factors about wave energy were calculated to assess the distribution of wave energy in these areas. The results show that it is effective and feasible to evaluate wave energy resources by altimeter and SAR (Synthetic Aperture Radar) data. We can carry out wave observations and wave energy assessment better by the combination of remote sensing data and wave model simulation.
