Lakes are important sources of atmospheric methane (CHANTON et al. 1989; THEBRATH1 991; MICHMERHUIZE&N STRIEGL1 996; SEMILETOV et al., 1996; PHELPS et al. 1998; DUCHEMIN et al. 1999; MAKHOV et al. 1999; HUTTUNEN et al. 2001). Permafrost landscapes of the Lena-Delta are often covered by polygonal tundra and patterned ground lakes, respectively. Up to now little is known about the contribution of those small but widespread lakes regarding their function as sources of atmospheric methane. Thus, surveying patterned ground lakes is a necessary part of investigations for estimating both global and local methane fluxes.
