We present wide-field , high-resolution imaging observations in ^ { 12 } CO 3 \rightarrow 2 and H _ { 2 } 1–0 S ( 1 ) towards a \sim 1 square degree region of NGC 2264 .
We identify 46 H _ { 2 } emission objects , of which 35 are new discoveries .
We characterize several cores as protostellar , reducing the previously observed ratio of prestellar/protostellar cores in the NGC 2264 clusters .
The length of H _ { 2 } jets increases the previously reported spatial extent of the clusters .
In each cluster , < 0.5 % of cloud material has been perturbed by outflow activity .
A principal component analysis of the ^ { 12 } CO data suggests that turbulence is driven on scales > 2.6Â pc , which is larger than the extent of the outflows .
We obtain an exponent \alpha =0.74 for the size-linewidth relation , possibly due to the high surface density of NGC 2264 .
In this very active , mixed-mass star forming region , our observations suggest that protostellar outflow activity is not injecting energy and momentum on a large enough scale to be the dominant source of turbulence .
