Abstract Methane concentrations are currently rising at a rate
of about 1% per year. Because methane plays an important role in the atmosphere
as a greenhouse gas, it is extremely important that we identify possible
methane sources and quantify their contribution to the Global Methane Budget.
This research determined the fate of methane produces on the ocean floor
in the Beaufort Sea of Alaska. Radiolabled carbon (C14) was used as a tracer
to determine the amount of methane consumed by
bacteria. The data from this experiment suggest that this area of the
Beaufort Sea may be a seasonal source of methane to the atmosphere as the
ice recedes during warmer months and the trapped methane is released. The
data also suggest that there may be a clathrate in the area which is releasing
methane into the water column.
