Australasian Mediterranean Water
From Glossary of Meteorology
(Abbreviated AAMW.) A Mediterranean Water mass formed in the Indonesian Seas (the Australasian Mediterranean Sea), also known as Banda Sea Water.
Of Pacific origin, it undergoes strong freshening as a result of heavy rainfall. AAMW is characterized by uniform salinity of 34.7 psu from the surface to depths of at least 1000 m, indicating strong mixing in the formation region. It can be followed in the Indian Ocean as a band of low- salinity water along 10°S as far west as Madagascar.
