Abstract

Abstract

Using the climatology data of temperature and salinity from the World Ocean Atlas 2013 (WOA2013) and the ocean current data of the Simple Ocean Data Assimilation version 3.3.1 (SODA v3.3.1), the vertical distribution and water mass sources of the Indonesian Throughflow (ITF) in its east pathway are analyzed, especially the sub-surface, intermediate and deep waters in the Molukka Sea and Halmahera Sea. The results show that the warmer and saltier subsurface waters around 24.5σ_θ(about 150 m) in the Molukka Sea come from the North Pacific (NP), with characteristics close to those of the NP Tropic Water (NPTW), while the subsurface water in the Halmahera Sea is closely related to the South Pacific Tropical Water (SPTW). For the intermediate water around 26.8σ_θ (about 480 m), which is characterized by low temperature and low salinity, the South Pacific (SP) water intrudes into the Molukka Sea, and further enters the Halmahera Sea from the southwest straits. In the transition layer between the subsurface and intermediate waters, the waters in the Molukka Sea and Halmahera Sea are mixed waters from the NP and the SP. There is water exchange between the two seas. In the deep layer around 27.2σ_θ (about 850 m), the water in the Molukka Sea is inclined to being from the northern Banda Sea and the Selan Sea. The deep water in the Halmahera Sea is isolated without direct exchange with the Pacific water due to topographic barrier.
