A method of seismic surveying A method of seismic surveying comprises the step of acquiring imaging seismic data relating to an underlying geological structure at a survey location and simultaneously, or substantially simultaneously, acquiring statics seismic data relating to the near-surface at the survey location. The controller, the fluid source, the negative pressure source, and the canister are carried by the housing. Coating compositions may also be tailored to provide a balanced combination of abrasion resistance, impact resistance, and weatherability. Lastly, the present invention is also drawn to methods and compositions for increasing the efficacy of the macrocyclic lactone compounds against resistant nematode or resistant arthropod pests which comprise administering to a mammal or applying to crops and the like a pesticidal enhancing effective amount of a multidrug resistance reversing agent. The ball stoppers are characterized as having a maximum cross-sectional size that is equal to or less than the size of the maximum cross-section of the balls of the chain.
