  We have conducted a search for new strong gravitational lensing systems in
the Dark Energy Spectroscopic Instrument Legacy Imaging Surveys' Data Release
8. We use deep residual neural networks, building on previous work presented in
Huang et al. (2020). These surveys together cover approximately one third of
the sky visible from the northern hemisphere, reaching a z band AB magnitude of
~22.5. We compile a training sample that consists of known lensing systems as
well as non-lenses in the Legacy Surveys and the Dark Energy Survey. After
applying our trained neural networks to the survey data, we visually inspect
and rank images with probabilities above a threshold. Here we present 1210 new
strong lens candidates.
