Gas Pressure Dynamics in Small and Mid-Size Lakes

Dissolved gases produce a gas pressure. This pressure is the appropriate physical quantity for judging possibility of bubble formation and hence it central understanding exchange climate-relevant between (limnic) water atmosphere. The contribution ebullition has widely been neglected in numerical simulations. We present measurements from six lacustrine waterbodies Central Germany: including natural lake, drinking reservoir, mine pit sand excavation flooded quarry, small lignite opencast, which heavily polluted. Seasonal changes oxygen temperature are complemented by simulations nitrogen calculations vapor to quantify contributions their dynamics waters. In addition, accumulation monimolimnetic waters demonstrated. sum partial pressures yield quantitative value total reason processes can force at locations. conclusion, only number contribute decisively be crucial formation.
