The Ocean Heat Content of Lombok Strait Water Masses in 2011 – 2015
Abstract The Lombok Strait that located between the island of Bali and Lombok is one of the seas in Indonesia that connects the Pacific Ocean and the Indian Ocean. Therefore, the characteristics of the Lombok Strait waters get influence from those oceans. In this research, the analysis of water mass...
