Simulated area is located in 1°0’0» N – 4°30’0» N and 104°0’15»E – 110°30’0»E with a horizontal resolution 0.5′ (approximately 0.94 km). The average of root mean square error of current velocity between model and observation are 0.17 for zonal (v) and 0.20 for meridional (v) components. The results of signal analysis showed that the volume and heat transport is strongly influenced by the seasonal period. There was also weak and medium phase of El Niño and La Niña during 2010 – 2014 that affected volume transport. The average volume (heat) transport during 2010-2014 through Karimata Strait is -2.75 Sv (-0.031 PW), meanwhile the average volume (heat) transport during boreal winter and boreal summer are -0.66 Sv (-0.06 PW) and -0.38 Sv (-0.03 PW), respectively (1 Sv = 106 m3/s; 1 PW=1015 W). Southward total transport indicates that there are parts of South Chinese Sea-Indonesia seas flow through Karimata Strait.[/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]Current velocity,Hamburg shelf ocean models (HAMSOM),Horizontal resolution,Model and observation,Model experiments,Root mean square errors,Three-dimensional numerical modeling,Volume transport[/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][/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]1 Department of Earth Science, Faculty of Earth Sciences and Technology, Bandung Institute of Technology, Jalan Ganesha 10, Bandung 40132, Indonesia 2 Marine Research Centre, Agency for Marine & Fisheries Research & Human Resources, Ministry of Marine Affairs & Fisheries, Jalan Pasir Putih 1, Ancol Timur, Jakarta Utara 14430, Indonesia[/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/10.1088/1755-1315/162/1/012001[/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]
