This record describes the trace metal dataset from the MNF RV Franklin survey FR 07/1997, titled "TROPICS97 Tropical River-Ocean Processes in Coastal Settings." The survey departed Madang (Papua New Guinea) on August 4, 1997 and arrived in Townsville (QLD) on August 22, 1997.
Samples were collected from the Sepik river and from each end of the N-S transects (~ 150 km long) off the coast of PNG. These stations were upstream of the plume (145 E), off the Sepik and downstream, or in, the plume (144 E and 143 E). Samples were also collected along the equator 143 E, 147 E, 149 E and 152 E. Samples were generally collected from surface to ~ 300m except equator station at 152 E where samples were collected to 2000m.
Parameters: Concentrations of unfiltered (total dissolvable) cadmium, copper, iron, manganese and nickel. Four inshore stations and a Sepik river station (18 samples) included filtered (total dissolved) cadmium, copper, iron, manganese and nickel.
