P02_2004_aerosol

This dataset consists of atmospheric aerosol measurements collected during the CLIVAR/GO‑SHIP repeat hydrography section P02 from 15 June to 27 August 2004, a zonal transect in the North Pacific from roughly 134°E to 121°W. Station metadata, hydrographic data, and cruise documentation are provided by the CLIVAR & Carbon Hydrographic Data Office (CCHDO) under expocode 318M200406. Atmospheric aerosol samples were collected on replicate filters using an automatic sector-controlled aerosol sampling system mounted on the bow of the ship. Samples were analyzed for total trace elements (Fe, Al, Si, Ti, V, Mn, Pb) and subjected to seawater and DI water leach protocols to quantify soluble Fe(II), non-sea-salt sulfate, nitrate, oxalate, and Na, and to assess the fractional solubility of trace elements (Fe, Al, Si, Ti, V, Mn). The timestamp is in UTC. For a full description of sampling protocols and analytical methods see: Buck, C.S., W.M. Landing, J.A.Resing, and G.T.
