The results of measurement of temperature and salinity at 18 obeservation stasions of Ekspedisi Teluk Weda in March 2013 were used to study the mixing of water masses in Weda Bay in March 2013. This water masses mixing analysis was processed using OMP method, assuming the source water masses was from Pacific Ocean, specifically PSW (Pacific Surface Water), SPSW (South Pacific Subtropical Water), NPSW (North Pacific Subtropical Water), NPIW (North Pacific Intermediate Water), AAIW (Antarctic Intermediate Water) Seram Sea, specifically SSW (Seram Surface Water), STW (Seram Thermocline Water), and SIW (Seram Intermediate Water) I & II, and Banda Sea, specifically BSW (Banda Surface Water), BTW (Banda Thermocline Water), and BIW (Banda Intermediate Water) I & II. <br /> <br /> <br /> The result of this research indicates PSW, NPSW, SPSW, and SIW II affecting the mixing of water masses in all of Weda Bay region. Mixed layer is dominated by PSW, contributing around 80%. Thermocline layer occurs water masses mixing among SPSW, contributing around 50% &#8722; 70%, NPSW, contributing around 10% &#8722; 20%, and SIW II, contributing around 20% &#8722; 40%. Intermediate layer occurs water mass mixing between SIW II, contributing around 80%, and SPSW, contributing around 20%. The presence of BSW is less then 5% in the east of the mouth of Weda Bay and it do not affect the mixing of water masses in the Weda Bay. Residual values of mass conservation is approximately 1% &#8722; 11% at &#963;t = 20,7 kg/m3 &#8722; 21,5 kg/m3 in mixed layer (&#8804; 91 m) which indicate there is another water mass or local water mass in the Weda Bay. Water masses mixing in all region of Teluk Weda are dominated by PSW in the mixed layer, SPSW in the thermocline layer, and SIW II in the intermediate layer.
