	abstract = {Widespread gas venting along the Cascadia margin is investigated from acoustic water column data and reveals a nonuniform regional distribution of over 1100 mapped acoustic flares. The highest number of flares occurs on the shelf, and the highest flare density is seen around the nutrition-rich outflow of the Juan de Fuca Strait. We determine \~{}430 flow-rates at \~{}340 individual flare locations along the margin with instantaneous in situ values ranging from \~{}6 mL min-1 to \~{}18 L min-1. Applying a tidal-modulation model, a depth-dependent methane density, and extrapolating these results across the margin using two normalization techniques yields a combined average in situ flow-rate of \~{}88 {\texttimes} 106 kg y-1. The average methane flux-rate for the Cascadia margin is thus estimated to \~{}0.9 g y-1m-2. Combined uncertainties result in a range of these values between 4.5 and 1800\% of the estimated mean values.},
