RV Investigator Voyage IN2015_E04 In-Line Aerosol Sampling for Trace Metals Data

This record describes the End of Voyage archive from the Marine National Facility RV Investigator trial voyage IN2015_E04. This is a trace metals and micronutrients trial voyage for the RV Investigator departing Hobart on the 26th April and returning to Hobart on the 28th April, 2015.
This record describes the data collected by In-line aerosol sampling for trace metal analysis. Marine aerosols were collected on acid cleaned Whatman 41 47 mm filters housed inside an all PFA in line filtration system (Curtin University) in the aerosol lab. Duplicate samples were taken using 1) all PFA tubing from the aerosol in intake and 2) stainless tubing from the aerosol intake to the manifold and PFA tubing from the manifold to the filter. Flow meters and pumps (CSIRO, O&A, Aspendale). Sampling only occurred when the wind direction came from the "clean air" sector. Samples are stored frozen.
