We present ALMA CO(2-1) observations toward a massive infrared dark cloudG28.37+0.07. The ALMA data reveal numerous molecular (CO) outflows with a widerange of sizes throughout the cloud. Sixty-two 1.3 mm continuum cores wereidentified to be driving molecular outflows. We have determined the positionangle in the plane-of-sky of 120 CO outflow lobes and studied theirdistribution. We find that the distribution of the plane-of-sky outflowposition angles peaks at about 100 degree, corresponding to a concentration ofoutflows with an approximately east-west direction. For most outflows, we havebeen able to estimate the plane-of-sky angle between the outflow axis and thefilament that harbors the protostar that powers the outflow. Statistical testsstrongly indicate that the distribution of outflow-filament orientations isconsistent with most outflow axes being mostly orthogonal to their parentfilament in 3D. Such alignment may result from filament fragmentation orcontinuous mass transportation from filament to the embedded protostellar core.The latter is suggested by recent numerical studies with moderately strongmagnetic fields.
