This paper compares measurements of organic amine using two complementary techniques, High Resolution Time-of-Flight Aerosol Mass Spectrometry (HR-ToF-AMS) and Fourier Transform Infrared Radiation (FTIR) Spectroscopy. Non-refractory (NR) amine fragments characterized by CxHyNp fragments measured by the AMS in the North Atlantic were found to have a continental source due to consistent correlations with tracers for oxidation indicating long-range transport and anthropogenic tracers including black carbon, nitrate, radon, and non-sea-salt potassium. Non-volatile (NV) amine groups characterized by N-H bonds measured by FTIR were found to have a marine source due to moderate-strong correlations with marine-derived tracers including chlorophyll a, chloride, sea salt, seawater DMS, and wind speed.
