Broadband Crust/Upper Mantle Studies Around New Zealand

PASSCAL BB instruments were deployed on S Island, in conjunction withthe S. Alpine Passive Experiment. In order to cover the entire region of interest, coverage was extended to Macquarie Island and Riverview in Austrialia, to Chatham Island and N. Island of NZ. Although surface wave tomography and its interpretation are the primary objectives, SKS polarization and several other body wave studies are anticipated. The data will be analyzed with the addition of data from a temp Australian National Univ. array in N.S.W and GSN, Geoscope, and other stations in SW Pacific.

PASSCAL宽频带地震仪（PASSCAL BB instruments）与南阿尔卑斯被动实验（S. Alpine Passive Experiment）一同部署于S岛。为覆盖全部感兴趣区域，观测范围拓展至澳大利亚的麦夸里岛（Macquarie Island）、里弗维尤（Riverview），以及新西兰的查塔姆岛（Chatham Island）与北岛。尽管本次研究的核心目标为面波层析成像（surface wave tomography）及其解译工作，但同时也计划开展SKS波偏振（SKS polarization）分析及其他多种体波研究。本数据集将结合澳大利亚国立大学（Australian National Univ.）位于新南威尔士州（N.S.W）的临时台阵数据，以及全球地震台网（GSN, Geoscope）与西南太平洋其他地震台站的数据进行联合分析。
