We present the detection of 107 pulsars with interstellar scintillation arcsat 856--1712\,MHz, observed with the MeerKAT Thousand Pulsar Array Programme.Scintillation arcs appear to be ubiquitous in clean, high S/N observations,their detection mainly limited by short observing durations and coarsefrequency channel resolution. This led the survey to be sensitive to nearby,lightly scattered pulsars with high effective velocity -- from a large propermotion, a screen nearby the pulsar, or a screen near the Earth. We measure thearc curvatures in all of our sources, which can be used to give an estimate ofscreen distances in pulsars with known proper motion, or an estimate of theproper motion. The short scintillation timescale in J1731$-$4744 implies ascattering screen within 12\,pc of the source, strongly suggesting theassociation between this pulsar and the supernova remnant RCW 114. We measuremultiple parabolic arcs of 5 pulsars, all of which are weakly scintillatingwith high proper motion. Additionally, several sources show hints of invertedarclets suggesting scattering from anisotropic screens. Building on this work,further targeted MeerKAT observations of many of these pulsars will improveunderstanding of our local scattering environment and the origins ofscintillation; annual scintillation curves would lead to robust screen distancemeasurements, and the evolution of arclets in time and frequency can constrainmodels of scintillation.
