Therefore, the characteristics of the Lombok Strait waters get influence from those oceans. In this research, the analysis of water masses in the Lombok Strait waters are investigated and analysed by using T-S diagram. The main data used are temperature and salinity from the HYbrid Coordinate Ocean Model (HYCOM) model in 2011 – 2015 with 1/12° × 1/12° horizontal resolution and vertical resolution up to 1500 m. The T-S diagram was used to identify the water masses contribution in the Lombok Strait and the ocean heat content (OHC) was calculated for each water mass. The Timor Sea Water (TSW) and Australasian Mediterranean Water (AAMW) contributed maximally in thermocline layer with 65.85% of the total heat content (1.12 × 1013 J/m2) and 24.46% (4.16 × 1012 J/m2). Then, The Antartic Intermediate Water (AAIW) and Banda Intermediate Water (BIW) contributed maximally in intermediate layer (500 – 1500 m) with 8.17% of total heat content (1.39 × 1012 J/m2) and 1.52% (2.59 × 1011 J/m2). In addition, the ocean heat content of each water mass was influenced by El-Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD). The ocean heat content of TSW and BIW increased when El-Nino and positive of IOD appeared and decreased during La-Nina and negative of IOD. Conversely, the ocean heat content of AAMW and AAIW decreased when El-Nino and positive of IOD appeared and increased during La-Nina and negative of IOD.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antartic intermediate waters,El Nino southern oscillation,Horizontal resolution,Hybrid coordinate ocean models,Indian ocean dipoles,Intermediate waters,Mediterranean waters,Vertical resolution[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]and Lombok Strait,El-Niño Southern Oscillation (ENSO),Indian Ocean Dipole (IOD),Ocean Heat Content,TS diagram,Water Masses[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research is fully funded by the Ministry of Research, Technology, and Higher Education Republic of Indonesia for the PDUPT scheme.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1755-1315/618/1/012014[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
