Evaluation of carbon uptake and emissions by forests in Korea during the last thirty years (1973-2002)
The apparent diapycnal diffusivity below the wind-driven surface mixed layer of the ocean was determined in an anticyclonic eddy in the eastern North Atlantic using sulfur hexafluoride (SF6) tracer data collected in June 1998. In this tracer experiment the downward penetration of SF6 was measured fo...
