Size fractionated particulate trace element concentrations from in-situ filtration near Station ALOHA during four R/V Kilo Moana cruises between September 2022 and August 2023

Size-fractionated particles were collected via in-situ filtration aboard the R/V Kilo Moana on four separate cruises (KM2210, KM2305, KM2306, and KM2311) at the Hawaii Ocean Time-Series study site, Station ALOHA, between 2022-08-30 to 2023-08-14. Marine particulate trace element concentrations were assessed via magnetic sector inductively coupled plasma mass spectrometry (ICP-MS). Many of these trace elements are required by marine organisms and can act as tracers of oceanographic processes. These data were used as part of the Hawaii Aerosol Time-Series (HATS) project to observe how seasonally variable atmospheric deposition of aerosol trace elements to the ocean impacts the compositional inventories of size-fractionated upper water column particulate trace elements.
