Sea levels at the Papua New-Guinea (PNG) coast responded to the 1986-87 ENSO event much as would be expected for points on the inshore edge of a western boundary current, driven by remote sea level disturbances. The first EOF of sea level in the region accounts for 60% of the variance, and shows a clear western boundary current signal. Sea level estimates from tide gauges and adjacent XBT's are in good agreement, so XBT data are used to supplement sea level results; specifically, we obtain an estimate of the western boundary current as a function of depth. The anomalous transport varied by about 15 Sverdrups during the event. The boundary current followed the Tobriand Island ridge, rather than the main PNG coastline, and appears to bifurcate along southern New Britain. A maximum response to the ENSO occured south of New Ireland, where steric sea level appeared to vary about 45 cm due to the ENSO event. (Résumé d'auteur)
