“…In addition to ENSO, other forcings may infl uence chlorophyll a concentrations in the Indonesian seas, such as tides (Ffi eld and Gordon, 1996;Susanto et al, 2000), the Madden-Julian Oscillation (MJO) (Madden and Julian, 1994), Kelvin and Rossby waves (Arief and Murray, 1996;Sprintall et al, 2000), monsoons (Asanuma et al, 2003;Moore et al, 2003;Susanto et al, submitted), and the Indian Ocean Dipole (IOD) (Saji et al, 1999;Webster et al, 1999). Because of its longitudinal extent (90° to 141°E), the Indonesian seas contain a signifi cant part of the tropical ocean productivity.…”

“…The Susanto et al (2000) study of the intraseasonal variability in the Makassar Strait, using a 1.5 year (1996 -1998) time series of currents at 300 m and 450 m, showed two significant ISV peaks: 35-60 and 70 -100 days. They suspected that the 35-60 day oscillations are associated with the Sulawesi Sea ISV (Qiu et al, 1999;Kashino et al, 1999) while the 70 -100 day oscillations are related to a Kelvin wave from the Indian Ocean (Qiu et al, 1999;Sprintall et al, 2000).…”

Intraseasonal variability [ISV] in the Makassar Strait thermocline is examined through the analysis of along-channel flow, regional sea level anomaly and wind fields from January 2004 through November 2006. The dominant variability of 45-90 day in the Makassar Strait along-channel flow is horizontally and vertically coherent and exhibits vertical energy propagation. The majority of the Makassar ISV is uncoupled to the energy exerted by the local atmospheric ISV: instead the Makassar ISV is due to the combination of a remotely forced baroclinic wave radiating from Lombok Strait and deep reaching ISV originating in the Sulawesi Sea. Thermocline depth changes associated with ENSO influence the ISV characteristics in the Makassar Strait lower thermocline, with intensified ISV during El Niño when the thermocline shallows and weakened ISV during La Niña.

“…When the outflow rate equals the accumulation rate of water mass or bottom pressure, the interface ceases to rise and a steady state is achieved. Volume fluxes of such outflows are useful measurements of interbasin water exchange, which are of fundamental interest to physical oceanography [Whitehead, 1989[Whitehead, , 1998Godfrey, 1996;Susanto et al, 2000;Susanto and Gordon, 2005] and ocean climate considerations [Dickson et al, 1999;Hansen et al, 2001;Gordon et al, 2003].…”

Estimation of interbasin transport using ocean bottom pressure: Theory and model for Asian marginal seas

The Asian Marginal Seas are interconnected by a number of narrow straits, such as the Makassar Strait connecting the Pacific Ocean with the Indian Ocean, the Luzon Strait connecting the South China Sea with the Pacific Ocean, and the Korea/Tsushima Strait connecting the East China Sea with the Japan/East Sea. Here we propose a method, the combination of the “geostrophic control” formula of Garrett and Toulany (1982) and the “hydraulic control” theory of Whitehead et al. (1974), allowing the use of satellite‐observed sea‐surface‐height (SSH) and ocean‐bottom‐pressure (OBP) data for estimating interbasin transport. The new method also allows separating the interbasin transport into surface and bottom fluxes that play an important role in maintaining the mass balance of the regional oceans. Comparison with model results demonstrates that the combined method can estimate the seasonal variability of the strait transports and is significantly better than the method of using SSH or OBP alone.
