Ebullition Regulated by Pressure Variations in a Boreal Pit Lake

Methane ebullition from lakes is an important contributor to atmospheric greenhouse gases. However, typically sampled at intervals greater than the duration of events, limiting our understanding factors controlling this flux. Here, we present high-frequency data a single site in boreal pit lake during open-water season between June 24 and 21 October 2018. We record every 30 min for first 2 months, then minute next months. During 4-month period, events were recorded. These generally lasted 2–4 days response low pressure systems. The peaks corresponded troughs pressure. provide empirical equations that incorporate threshold model time-series events. Minor gradual variations mud temperature had no apparent effect on observed
