Kondisi Suhu, Salinitas, pH dan Oksigen Terlarut di Perairan Terumbu Karang Ternate, Tidore dan Sekitarnya

Abstract

Observation of water temperature, salinity, pH and dissolved oxygen in coral reef of Ternate, Tidore and surrounding areas has been carried out in July 2018. The results of statistical analysis using the t-test indicate that the water temperature and dissolved oxygen in the surface layer and the bottom layer is significantly different, while Salinity and pH weren’t differ significantly between both layers. The correlation between sea water depth variations with temperature, salinity, pH and oxygen levels showed relatively small differences but were still within the threshold of marine biota life. On the surface layer, 85.71% positive AOU value were obtained and a negative AOU of 14.29%, illustrates the presence of sites with higher oxygen consumption compared to oxygen production. The value of sea water temperature, salinity, pH and dissolved oxygen of coral reef areas in Ternate, Tidore and the surrounding areas has not shown negative impacts on the aquatic environment and is still adequate for coral reef growth
