These measurements are useful in characterizing marine sources of CH\u2084 in the Arctic.\r\n\r\nMeasurements were made using an Aerodyne Research direct absorption interband cascade laser spectrometer onboard the Swedish icebreaker Oden during the SWERUS-C3 expedition to the Arctic Ocean.","citations":"Berchet A, Pison I, Crill PM, Thornton B, Bousquet P, Thonat T, Hocking T, Thanwerdas J, Paris J-D, Saunois M (2020).
