LOCATION: Arctic Ocean
CAMPAIGN: PS122/4 (MOSAiC20192020)
BASIS: Polarstern
METHOD/DEVICE: Cavity ring-down spectroscopy (CRDS)
COMMENT: "For Leg 4 this device is located in dry lab 4 and connected to outside air. The outisde air is obtained at P-deck, tubed down and then shared with the halo-carbon analyser. This device is switched to outside air while no other air samples are analysed, so this is an interupted time series; Rec started right after leaving 12NM zone of Svalbard "
