  Using the ASTE 10 m submillimeter telescope and the 1.4 m Infrared Survey
Facility (IRSF), we performed an extensive outflow survey in the Orion
Molecular Cloud -2 and -3 region. Our survey, which includes 41 potential
star-forming sites, has been newly compiled using multi-wavelength data based
on millimeter- and submillimeter-continuum observations as well as radio
continuum observations. From the CO (3-2) observations performed with the ASTE
10 m telescope, we detected 14 CO molecular outflows, seven of which were newly
identified. This higher detection rate, as compared to previous CO (1-0)
results in the same region, suggests that CO (3-2) may be a better outflow
tracer. Physical properties of these outflows and their possible driving
sources were derived. Derived parameters were compared with those of CO
outflows in low- and high-mass starforming regions. We show that the CO outflow
momentum correlates with the bolometric luminosity of the driving source and
with the envelope mass, regardless of the mass of the driving sources. In
addition to these CO outflows, seven sources having NIR features suggestive of
outflows were also identified.
