USGS Groundwater Information: Branch of Geophysics
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:

Marine Seismic Training
Kansas District, October 15 to 18, 2001
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.
following summarizes the tasks accomplished each day:
of marine seismic fundamentals, survey planning, and GPS fundamentals.
Class exercises consisted of navigation message design and system
setup and breakdown.

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.
data acquisition, processing, and interpretation training for the
Kansas District included:
- 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
- Step-by-step instruction on data analysis and interpretation,
including real-time data viewing as well as post-processing and
- 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.
