Discovering the Indonesian Throughflow

IODP Expedition 356: Indonesian Throughflow

Week 6 of Expedition 356 (Indonesian Throughflow) consisted of completing operations at Site U1462 (including another successful downhole logging deployment in Hole U1462C) and the start of operations at Site U1463 (proposed site NWS-2A). The science party was able to finalize all outstanding reports from Site U1461, particularly downhole logging and stratigraphic correlation, and begin finaliz...

South China Sea throughflow impact on the Indonesian throughflow

[1] In 2008–2009 the Makassar throughflow profile changed dramatically: the characteristic thermocline velocity maximum increased from 0.7 to 0.9 m/sec and shifted from 140 m to 70 m, amounting to a 47% increase in the transport of warmer water between 50 and 150 m during the boreal summer. HYCOM output indicates that ENSO induced change of the South China Sea (SCS) throughflow into the Indones...

Pathways of Intraseasonal Variability in the Indonesian Throughflow Region

The recent INSTANT measurements in the Indonesian archipelago revealed a broad spectrum of time scales that influence Throughflow variability, from intraseasonal (20-90 days) to interannual. The different time scales are visible in all transport and property fluxes and are the result of remote forcing by both the Pacific and Indian Ocean winds, and local forcing generated within the regional In...

The Indonesian throughflow, its variability and centennial change

The Indonesian Throughflow (ITF) is an important component of the upper cell of the global overturning circulation that provides a low-latitude pathway for warm, fresh waters from the Pacific to enter the Indian Ocean. Variability and changes of the ITF have significant impacts on Indo-Pacific oceanography and global climate. In this paper, the observed features of the ITF and its interannual t...
