Archive of Digital Boomer and Chirp Seismic Reflection Data Collected During USGS Cruise 06FSH03 Offshore of Fort Lauderdale, Florida, September 2006

In September of 2006, the U.S. Geological Survey conducted geophysical surveys offshore of Fort Lauderdale, FL. This report serves as an archive of unprocessed digital boomer and Chirp seismic reflection data, trackline maps, navigation files, GIS information, Field Activity Collection System (FACS) logs, observer's logbook, 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/c/c106fl/html/c-1-06-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

2006年9月，美国地质调查局（U.S. Geological Survey）在佛罗里达州劳德代尔堡近海开展了地球物理勘探作业。本报告作为未处理的数字电火花震源（boomer）与Chirp地震反射数据、测线分布图、导航文件、地理信息系统（Geographic Information System, GIS）资料、野外活动采集系统（Field Activity Collection System, FACS）日志、观测员日志以及正式的联邦地理数据委员会（Federal Geographic Data Committee, FGDC）元数据的存档文件。此外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）制定的SEG-Y格式（Barry等，1975）存储，可通过商业软件或开源公有领域软件（如地震Unix（Seismic Unix, SU））进行下载与处理。本次存档还附带了示例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）。

如需了解本次地震勘探的更多详情，请访问http://walrus.wr.usgs.gov/infobank/c/c106fl/html/c-1-06-fl.meta.html

本数据集还可通过GeoMapApp（http://www.geomapapp.org/）与Virtual Ocean（http://www.virtualocean.org/）这两款地球科学勘探与可视化应用程序获取。
