Abstract:

Atmospheric methane data were collected by NRL personnel in the Arctic and subarctic regions from 1971 to 1979. These data show an average increase of approximately 0.5 to 0.6 per year increase. The data do not support the increase of 2 per year obtained by extrapolating methane measurements obtained from 1979 to 1981. No information is available from the NRL data to determine if the increase will continue at its present rate 2yr, decreases or become cyclic.
