Gas inlets were installed at the bow, on the top deck and in the mast of RV Poseidon. Atmospheric gas concentrations of CH4 and CO2 were measured continuously with a Picarro G2301-f analyzer. Concentrations are given as \"ppmV in dry air\".海神号（RV Poseidon）科考船的船首、主甲板及桅杆处均安装了气体进气口。 采用皮卡拉罗G2301-f型分析仪（Picarro G2301-f）对大气中的甲烷（CH4）与二氧化碳（CO2）浓度开展连续监测。 浓度以"干燥空气中的体积百万分浓度（ppmV）"标注。
