Analisa sebaran suhu permukaan laut dari Data Citra Satelit NOAA/AVHRR dan hubungannya dengan penaikan massa air di Perairan Selat Makasar

Abstract

The objective of sea observations is to know the distribution of oceanography parameters. These parameters can describe water condition, for example upwelling process, water mass circulation, and other phenomenas. One of the important oceanography parameter is the sea surface temperature. The sea surface temperature data can be measured directly or be estimated by using NOAA/AVHRR(National Oceanic and Atmospheric Administration/Advanced Very High Resolution Radiometer) satellite. This paper aim is to discuss the utilization of satellite NOAA/AVHRR data to estimate the sea surface temperature on Macassar Strait. The results show that the sea surface temperature on Macassar Strait vary between 27.5°C-31.0°C. This temperature is 1°C higher than in situ data measurement. In middle of Macassar Strait the thermal front can be seen. Mean while the upwelling is not seen on image of NOAA/AVHRR data.
