NOAA/CDML atomospheric methane data for the period 1983-1990 from shipboard flask sampling. Technical report
The memorandum presents atmospheric methane data obtained through the shipboard sampling component of the NOAA/CMDL global cooperative flask sampling program. A significant part of the program has involved flask sampling from a commercial container ship, the Southland Star, on regular crossings of the Pacific Ocean between the U.S. west coast and New Zealand. Shipboard flask sampling has also been carried out on a variety of oceanographic research expeditions. Tabulations are provided for individual flask measurements and annual mean methane mixing ratios for 14 sites spaced every five degrees of latitude across the Pacific Ocean between 30 deg N and 35 deg S. The methane data from the Southland Star are also shown as time series plots. The locations of flask sampling on the oceanographic research expeditions are shown in a series of maps. The flask methane data from these expeditions are shown as a series of plots of methane versus latitude. A brief history of the development of the sampling program is included. Flask sampling methods, and analytical and calibration procedures are documented.
