Res. Lett., 34, L22603, doi:10.1029/2007GL031344. Introduction Auxiliary material consists of one figure. 1. 2007gl031344-fs01.eps Wind speed versus methane air-sea flux of the 280 km2 study area. W92-Wanninkhof [1992], N00-Nightingale et al. [2000], M01-McGillis et al. [2001], H06-Ho et al. [2006] curves illustrate relationship of wind speed and methane air-sea flux. The black dot represents the calculated methane flux and the error bars show the difference in wind speed derived from the five recording stations (Fig. 1a). 1
