All deployments were initiated at Station ALOHA. Sinking particulate metals were collected in Particle Interceptor Traps (PITs) with ~100 ppt trace-metal clean brine derived from seawater over a period of approximately 2.5 days. Following recovery, triplicate PIT traps were filtered onto 0.2 micron polyethersulfone (PES) filters. Filters were subject to a 2-stage digestion: 1) a \"Berger\" leach consisting of hydroxylamine and acetic acid, to dissolve labile trace metals, and 2) a digestion with nitric acid and hydrofluoric acid to dissolve recalcitrant metals. Dissolved metals for each leach were 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.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nTime_deployment (unitless)\nTime_recovery (unitless)\ntime (Time_deployment_utc, seconds since 1970-01-01T00:00:00Z)\nTime_recovery_UTC (seconds since 1970-01-01T00:00:00Z)\ndepth (m)\nlongitude (degrees_east)\nlatitude (degrees_north)\nReplicate (unitless)\nFlux_Al_labile (micromoles per square meter per day (umol/m2/day))\nFlux_Al_labile_qc (unitless)\nFlux_Ti_labile (micromoles per square meter per day (umol/m2/day))\nFlux_Ti_labile_qc (unitless)\nFlux_Mn_labile (micromoles per square meter per day (umol/m2/day))\nFlux_Mn_labile_qc (unitless)\nFlux_Fe_labile (micromoles per square meter per day (umol/m2/day))\n...
