  Determining the physical mechanisms that extract energy from turbulent
fluctuations in weakly collisional magnetized plasmas is necessary for a more
complete characterization of the behavior of a variety of space and
astrophysical plasmas. Such a determination is complicated by the complex
nature of the turbulence as well as observational constraints, chiefly that in
situ measurements of such plasmas are typically only available at a single
point in space. Recent work has shown that correlations between electric fields
and particle velocity distributions constructed from single-point measurements
produce a velocity-dependent signature of the collisionless damping mechanism.
We extend this work by constructing field-particle correlations using data sets
drawn from single points in strongly driven, turbulent, electromagnetic
gyrokinetic simulations to demonstrate that this technique can identify the
collisionless mechanisms operating in such systems. The correlation's
velocity-space structure agrees with expectations of resonant mechanisms
transferring energy collisionlessly in turbulent systems. This work motivates
the eventual application of field-particle correlations to spacecraft
measurements in the solar wind, with the ultimate goal to determine the
physical mechanisms that dissipate magnetized plasma turbulence.
