attribute NC_GLOBAL summary String We collected and analyzed water samples for dissolved and total dissolvable trace metal concentration on Hawaii Ocean Time-series (HOT) cruises between December 2020 and November 2023. All samples were collected at Station ALOHA. Samples were collected using a trace metal rosette. Approx. 12 depth samples were collected for each cruise within the upper 350 m of the water column. 
 
Dissolved metal measurements reflect samples filtered through a 0.2 micron filter. Total dissolvable metal measurements represent unfiltered samples. Both sample types were acidified for > 2 months after collection and metals were extracted via chelating resin (Nobias PA-1) and analyzed by inductively coupled plasma mass spectrometry at the University of Hawaii at Manoa using a Thermo Scientific iCAP-TQ mass spectrometer. 
 
This dataset is part of a larger study focused on the cycling of trace metals in the North Pacific Subtropical Gyre, and is embedded within the HOT program.
