Temperature-Salinity stratification in the Eastern Indian Ocean using argo float

The spatial and temporal of Temperature and Salinity in the Eastern Indian Ocean (EIO) are studied by using Argos data. EIO consisting of Pacific seawater mass which passing through Indonesian seas and mix with Indian Ocean itself that form complex formation. It reveals link among ITF, SEC, Leeuwin Current, and SJC and routes into global circulation. The purpose of this study is to describe the main physical properties variability based on Argo Floats data. The dataset is used from 80 Argo Floats during 1999-2016 within area south of Java to west of Australia with depth range 0-2000 meters. The result shows that vertical temperature and salinity profile quite homogeny near Sunda Island-West Australia. Monthly spatial distribution of temperature is founded 15-30° C, and varying in lesser Sunda. Vertical profile in 4 sections is shallow at near Java, but shows differences in 25 horizontal. Salinity profile is having range 25-34 psu. ITF is contributing to EIO mixing. Finally, salinity is a parameter that affects the EIO dynamics especially in near Australia basin. The SEC variability showed clear in between 10°S to 15°S.
