IRIS Community Wavefield Experiment in Oklahoma

This experiment made use of cutting-edge three-component nodal-type sensors in conjunction with more conventional broadband sensors and infrasound transducers. The concept for this experiment resulted from an IRIS call for ideas on how to incorporate these nodes into a full wavefield observing system. Concept contributors included: Heather DeShon, Brian Stump, Chris Hayward, M. Beatrice Magnani (Southern Methodist University); Michael Brudzinski (University of Miami-Ohio); Susan Bilek (New Mexico Tech); and Chuck Langston (University of Memphis). In addition, community members contributed their own nodes to this effort (Marianne Karplus - University of Texas, El Paso and FanChi Lin - University of Utah). The deployment was conducted in mid June, 2016 and included over 50 staff, students and faculty from across the IRIS community with one of our goal being to expand the experience in deploying nodes. The study area was chose to be in north central Oklahoma to allow for recording of expected local seismicity along with array designs to allow for enhance detection of regional and teleseismic signals. The experiment was done in collaboration with a separate experiment in the same area, led by Katie Keranen (Cornell University).

本实验采用了尖端的三分量节点式传感器（three-component nodal-type sensors），并结合了更为传统的宽频带传感器与次声换能器（infrasound transducers）。本实验的设计理念源自IRIS发起的一项创意征集活动，主题为如何将此类节点集成至全波场观测系统（full wavefield observing system）。参与该理念构思的人员包括：Heather DeShon、Brian Stump、Chris Hayward、M. Beatrice Magnani（南卫理公会大学）；Michael Brudzinski（迈阿密大学-俄亥俄分校）；Susan Bilek（新墨西哥理工大学）以及Chuck Langston（孟菲斯大学）。此外，社区成员也为本次工作提供了自有节点设备，包括Marianne Karplus（德克萨斯大学埃尔帕索分校）与FanChi Lin（犹他大学）。本次部署工作于2016年6月中旬开展，共有来自IRIS各合作机构的50余名科研人员、学生与教职员工参与，其中一项核心目标为拓展节点部署相关的实践经验。本次研究选定俄克拉荷马州中北部作为实验区域，以便记录预期的本地地震活动，同时通过台阵设计强化对区域及远震信号的探测能力。本实验与由Katie Keranen（康奈尔大学）主导的同区域另一项实验开展了合作。
