4D-Earth Initiative:
A Community Geologic Model and New Scientific Initiative
for Illuminating the Evolution of the North American Continent
A new initiative and a successor to the EarthScope Program
Mike Williams, Steve Whitmeyer, Laura Webb,
Terry Pavlis, John Hole, Becky Flowers, and others
1.
Expand the primarily 3-D geophysical focus that captured a snapshot of
present day North America into the 4th dimension of time
Geochronology
1.
Illuminate the crustal component that was below the resolution of much
of the USArray image
Active-source seismology
1.
Develop a Community Geologic Model to build a 4-dimensional image
of the continent
Cyberinfrastructure
Idea Paper
4D-Earth Initiative:
A Community Geologic Model and New Scientific Initiative
for Illuminating the Evolution of the North American Continent
Starting Point:
Build a set of time slices where each
time slice is a digital model in itself,
incorporating data sets, hypotheses,
simulations, models of structure,
stratigraphy, geochronology, geomorphology, petrology, lithospheric and crustal
dynamics, and high-resolution geophysics
and environmental sensing enabled by
observational networks such as those
built by EarthScope.

Next Steps:
Fall, 2016 - 2017
• Workshops to synthesize what we have learned from
EarthScope and other projects on the structure and evolution of
Laurentia / North America through time. Details to follow…
• Identify one or two pilot time slices in which to begin to develop
the community model and explore the necessary
cyberinfrastructure
