Abstract

A WET Labs SAFire multi-spectral and absorption meter was used to identify dissolved poly-aromatic hydrocarbons and anomalous biological activity in near surface waters. Over 6000 km of data were collected southwest of Noumea. No obvious hydrocarbon anomalies were detected but blue-green algal blooms (Trichodesmium ?), identified also by satellite and biological analysis (Dupouy et al, 2000), were commonly encountered in the survey area. An extremely high absorption anomaly centred at 162.7 deg E and 22.7 deg S, with a strong algal fluorescence signature at 440 nm excitation, is also likely to be from the same source.
