| Dissolved aluminum (Al) and manganese (Mn) and total dissolvable Al and Mn from surface water samples collected during three cruises in 2010 in the northern Gulf of Alaska | Surface waters were sampled by underway pumping of seawater through Teflon-lined tubing using a technique adapted from that of Vink et al. [2000], with the intake positioned a few centimeters forward from, and mounted to, a PVC towfish towed ~2 meters (m) below the surface. The towfish was suspended by a polyester line from a boom extending ~10 m from the starboard side of the ship to minimize contamination. Seawater was pumped using a shipboard air-operated Teflon-lined diaphragm pump to a shipboard clean lab, where both filtered and unfiltered samples were collected. Acropore cartridges (0.45 micrometers (μm)) were used to filter the surface water samples inline under N2 pressure, without requiring any intermediate collection vessel, after flushing 10 liters (L) through each cartridge before first use. Surface water salinity, temperature, and sampling depth were logged once per minute using a YSI Sonde attached to the towfish.
