Abstract. The intermittent turbulent transport in the Scrape-Off Layers of Alcator C-Mod, DIII-D, and NSTX is studied experimentally. In C-Mod and NSTX the turbulence is imaged with a very high density of spatial measurements. The 2D structure and dynamics of emission from a localized gas puff are observed, and intermittent features (also sometimes called ``blobs'') are typically seen. The intermittent features are often born near the separatrix and propagate predominately outward and poloidally. Qualitatively similar features (but with a larger size-scale) are also seen in the NSTX SOL. On DIII-D the edge turbulence is imaged using BES, and similar intermittent features are seen. Also the fluctuating components of density, temperature and poloidal electric field are simultaneously measured using a reciprocating Langmuir probe array. The density and temperature fluctuations have strongly non-Gaussian statistics, and events with amplitudes above 10 times the mean level are responsible for large fractions of the net particle and heat transport. The experimental observations from C-Mod are compared with numerical simulations of electromagnetic turbulence in a 3D flux tube at the plasma edge.
