| Summary: | This study aims to examine the seasonal variation of sea surface salinity (SSS) in Indonesian
waters based on combination of Aquarius satellite imagery data for 2012-2014 and SMAP
(Soil Moisture Active-Passive) satellites in 2015-2016 with statistical approach. The
validation results between sea surface salinity data of Aquarius satellite imagery with field
data buoy array of RAMA during 2012-2014 and TRITON 2012-2016 showed a low error
value of 0.0028 PSU and 0.0051 PSU respectively. The average surface salinity in
Indonesian waters from 2012-2016 is worth 33.52 PSU, spatially the maximum value occurs
in the Sulawesi Sea with a value of 34.18 PSU and a minimum value of 32.7 PSU in the Java
Sea, whereas the maximum temporal value occurs in September with a value of 33.85 PSU
and a minimum value of 33.20 PSU in April. From 2012-2016, salinity value in Indonesian
waters generally experiences a minimum increase of 0.004 PSU per year, while the
downward trend occurs only in the West Sumatra region of -0.078 PSU per year. Positive
Iods in 2012 and 2015 do not have a significant impact on surface salinity changes when
compared to EL-Nino 2015 which increases the value of surface salinity to a maximum of
1.5 PSU. |
