Geosciences
Measurement Facility (GMF)
The
field and laboratory work is supported by GMF, a DOE supported facility
designed
to develop and maintain a variety of geophysical and geoscience
measurement
equipment. For example, research on piezoelectric sources and borehole
sensor arrays, as well as high frequency seismic recording, has
been supported
by GMF for over 10 years. GMF is the focal point for an extensive
inventory
of complex scientific equipment used for LBNL projects, with responsibility
for the maintenance, upgrading, training and field operations of
this hardware. GMF will allow for management of the full complement
of sophisticated
field instrumentation and associated support vehicles necessary
to
test and develop a piezoelectric multi-source phased array. GMF
maintains a
state-of-the-art multidisciplinary field instrumentation facility
in support of
various environmental, geophysical and hydrogeological research
programs at Berkeley
Lab. GMF assists in development of new instrumentation and field
methods for investigating the subsurface and its processes by providing
professional in-field technical support for scientific staff, and
management of the complex and varied field studies required in scientific
research programs.
LBNL's
GMF includes electronic and mechanical technicians and shop facilities,
field
support vehicles (including wireline and recording trucks) and a
three borehole
test facility. A list of the relevant facilities and equipment at
GMF for
