Archive of Digital Boomer Seismic Reflection Data Collected During USGS Field Activity 02LCA02 in Lakes Ada, Crystal, Jennie, Mary, Rice, and Sylvan, Central Florida, July 2002

In July of 2002, the U.S. Geological Survey and St. Johns River Water Management District (SJRWMD) conducted geophysical surveys in Lakes Ada, Crystal, Jennie, Mary, Rice, and Sylvan, Florida. This report serves as an archive of unprocessed digital boomer seismic reflection data, trackline maps, navigation files, GIS information, FACS logs, and formal FGDC metadata. Filtered and gained digital images of the seismic profiles are also provided. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG-Y format (Barry and others, 1975) and may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU). Example SU processing scripts and USGS software for viewing the SEG-Y files (Zihlman, 1992) are also provided. For more information on the seismic surveys see http://walrus.wr.usgs.gov/infobank/b/b402fl/html/b-4-02-fl.meta.html These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.2002年7月，美国地质调查局（U.S. Geological Survey）与圣约翰斯河水域管理区（St. Johns River Water Management District, SJRWMD）在佛罗里达州的阿达湖、水晶湖、珍妮湖、玛丽湖、赖斯湖与西尔万湖开展了地球物理勘探工作。本报告作为未处理的数字鸣震地震反射数据、测线地图、导航文件、地理信息系统（Geographic Information System, GIS）信息、FACS测井记录以及正式联邦地理数据委员会（Federal Geographic Data Committee, FGDC）元数据的存档文件，同时还提供了经滤波与增益处理的地震剖面数字图像。 存档的地震道数据采用标准勘探地球物理学家协会（Society of Exploration Geophysicists, SEG）SEG-Y格式（Barry等人，1975）存储，可通过商业或公有领域软件（如地震Unix（Seismic Unix, SU））进行下载与处理。此外还附带了示例SU处理脚本，以及用于查看SEG-Y文件的美国地质调查局软件（Zihlman, 1992）。 如需了解此次地震勘探的更多详情，请访问：http://walrus.wr.usgs.gov/infobank/b/b402fl/html/b-4-02-fl.meta.html 本数据集亦可通过GeoMapApp与Virtual Ocean这两款地球科学勘探与可视化应用获取，对应网址分别为http://www.geomapapp.org/ 与http://www.virtualocean.org/。
