Entry Title High-resolution measurements of CH4 and CO2 in the surface seawater
Abstract Surface ocean methane was monitored from August 31 to September 19 using a CRDS CH4/CO2 analyzing system along the cruise track of R/V Araon from Barrow, U.S.A., to Nome, U.S.A., while conducting an expedition in The Chukchi Sea and East Siberian Sea. The air inlet to the instrument was located at 29 m asl and the sea water inlet was located at 7m depth.
Purpose To investigate ocean emissions of CH4 and CO2 in the Arctic Ocean
