Distributed natural gas venting offshore along the Cascadia margin

Methane venting is a widespread phenomenon at the Cascadia margin, however a comprehensive database of methane vents at this margin is lacking. Here the authors show that the margin-wide average methane flow-rate ranges from ~4 × 106 to ~1590 × 106 kg y−1 and is on average around 88 ± 6 × 106 kg y−1...
