We have discovered a state of superfluid turbulence in convecting dilute solutions of /sup 3/He in superfluid /sup 4/He which has many features of superfluid turbulence in straight channels. The characteristics of this state, determined by precise measurement of heat flow, are noisy temperature fluctuations and decreased thermal heat-transport efficiency relative to a ''quiet'' convecting state. There exists a ''critical flow field'' analogous to a critical velocity in pipe-flow superfluid turbulence, below which the noisy state is absent.
