Abstract

Water collected with 30-1. Niskin bottles on rusty hydrographic wire at three stations contained five times as much particulate iron as water collected with the same samplers on new, aluminized wire. Two samples of particulate matter filtered from the air in a laboratory on the oceanographic R.V. Trident had iron concentrations from 20 to 30 times that in similar samples of uncontaminated marine air. Observations of particulate iron in seawater in which rusty hydrographic wire was used may be affected by contamination. Although samples filtered on board ship may be contaminated by particles in the air, the collection of water samples in metal or even in plastic bottles attached to corroded wire seems the most likely source of the high concentrations of particulate iron that have been reported in the literature. © 1975.
