Fly River estuary (salinity gradient, Gulf of Papua)
Gulf of Papua, Fly River estuary, Papouasie-Nouvelle-Guinée
Rivers and surface water
- Type
- River or surface water
Fly River salinity transect sampled from 10 to 16 January 1999 (TROPICS Leg 7, monsoon), from fresh water (0.1 ‰) to 33 ‰. 187Os/188Os rises with salinity from 0.6165 to 0.913, below the open-ocean value (1.06); Os stays low (4.6 to 5.7 pg/kg), below the oceanic range (Martin et al., 2001). Coordinates: river end-member (7-10).
