Recent District Training

OGW BG provides formal and informal training to USGS offices and staff.  Many districts ask, "What would a district training look like?"  This page provides an overview of a recent district training to give you an idea of what OGW BG staff can do for USGS WRD districts across the country.  Please keep in mind that each training is customized to address the particular needs of a district or office, so each training will look different: contact the Branch to discuss your particular training needs.


Swept-Frequency Marine Seismic Training
Kansas District, October 15 to 18, 2001


 [Photo: Training participant processing seismic data.] Eric White of the OGW, Branch of Geophysics provided training in swept-frequency marine seismic data acquisition, processing, and interpretation for five staff from the USGS Kansas District from October 15 to October 18, 2001. A member of the Nebraska District was also present for the first three days of training. The training was conducted in the Kansas District office and on-site at Lake Olathe and Cedar Lake.

The following summarizes the tasks accomplished each day:
Monday: Overview of marine seismic fundamentals, survey planning, and GPS fundamentals. Class exercises consisted of navigation message design and system setup and breakdown.
Tuesday: Data collection on Lake Olathe
Wednesday: Data collection on Cedar Lake
Thursday: Data management, data processing and interpretation exercises were conducted. A round-table discussion on the advantages and limitations of the swept-frequency marine seismic method and associated training was also conducted.

  • Guidance in preparation and set-up of field equipment and continuous seismic profiling survey design.
  • Field-based practical experience running swept-frequency marine seismic profiling survey lines transverse to the long axis of the lakes.
  • Use of the OGW BG continuous seismic profiling equipment, including a swept-frequency tow-fish with pulse bandwidth of 2 to 15 kHz; acquisition console; tow-fish control unit; plotter for real-time printing of data; and related data viewing and processing software.
  • Step-by-step instruction on data analysis and interpretation, including real-time data viewing as well as post-processing and interpretation.
  • Sample integration of seismic data with additional geophysical data from previous studies: shallow seismic reflections were correlated to gravity cores previously collected from Lake Olathe.
  • Data was backed up and copies left with district participants.
  • Access to OGW BG staff for post-training follow-up and support via phone and e-mail.
