Seawater (34.94 ‰) sampled in July 1997, south-east trade wind season and El Niño period, when riverine inputs from New Guinea were very low. 187Os/188Os of 0.844, below the open-ocean value (1.06): the authors see a share of unradiogenic Os supplied by rivers and weathering of New Guinea ultramafic rocks.
