1차 PACSWIN 해저케이블 워크샵

Abstract

The western Pacific is an important region because of strong western boundary currents, closely-coupled atmosphere and ocean, and the upper-limb return flow of the global overturning circulation through the marginal seas of Indonesia. The ITF is complex and passes through many straits. Only recently were simultaneous mooring measurements (the INSTANT project, 2004-2006) carried out in this region to measure the ITF velocity and transport. It is very costly to maintain a set of moorings for timescales longer than a few years, however, and submarine cables allow long-term measurements to be continued on a sustainable basis. Several submarine cables cross straits through which the ITF flows (Figure 2). In particular, two cables cross Makassar Strait, which contains the majority (estimated at 70-80%) of the ITF transport. PACSWIN has set the submarine cable as one of its priority monitoring components along with ADCP and XBT using commercial ships, satellite, moorings and floats. The cable routes in the Indonesian seas avoid the magnetic equator, which lies to the north near Mindanao.
