Preliminary Study of Ocean Acidification: Relationship of pH, Temperature, and Salinity in Ohoililir, Southeast Maluku

Abstract Changes in pH, temperature, and salinity in seawater can indicate the occurrence of ocean acidification. The purpose of this research was to study changes in acidity that occur in Ohoililir waters, Southeast Maluku, which is part of the Banda Sea. This research was conducted in March 2019 as a study of the prefix of oceanic equities in the Southeast Maluku region which is part of the Banda Sea which is currently one of the priority researches in Indonesia, and sampling at 10 points. The results obtained were pH average of 8.69, temperature average of 29.74°C, and salinity of 33.23. The correlation between pH and temperature is -0.097 and the correlation between pH and salinity is in the range of -0.054 which indicates a very weak relationship between pH and temperature and salinity. Besides, pH has a negative correlation to temperature and salinity. This shows the need for further research on the relationship between these three or more parameters to see the effect on the ocean.
