Tracing the source of sediment and phosphorus into the Great Barrier Reef lagoon

McCulloch, Malcolm; Pailles, Christine; Moody, Philip; Martin, Candace


Neodymium and strontium isotopic systematics show that terrestrial phosphorus (P) entering the inner Great Barrier Reef (GBR) is dominated by the transport and dispersal of fine-grained basaltic soils. Soils derived from alkali basalts have high total P (3000-4000 mg/kg) and distinctive143Nd/144Nd isotopic signatures (εNd ∼+3 to +5), while the more common Palaeozoic granitic/metamorphic soils have much lower total P (300-600 mg/kg) and143Nd isotopic signatures ( εNd ∼-8). The nearshore...[Show more]
