N2  - Surface wave data acquisition by landstreamer with flat baseplates produces nearly identical dispersion curves to that from planted geophones. Dependence on geophone frequency and good coupling is negligible and repeatability is fair. `Pseudo' 2D profiling using 1D inversion at high shot density produces accurate subsurface images. However, `pushing' a spread over the termination of a soft-layer pinchout can lead to overestimation of its lateral extent by up to 20% of the spread length. Shorter spreads show less lateral scattering but large shot-geometry dependence, and the response is dominated by the material under the shot / nearer-offset channels.
